Pearl's mod/build LT rear/DK +3.5 LT/Custom Baja Bumper/Thorley Headers/Manual T-case

Also readdressing the FJ tank. I had moved the rear strap to accommodate the shorter tank, and didn't really leave a solid mounting point for that strap.

So I found a tab on the upper link cross member with an 8mm nut welded on there, then used some old bed frame and fabbed up bracket. Now I'll have a double shear on a Grade 8 bolt, with a support brace in the middle of the bolt. A little paint and it should be good to go.

The pursuit of more travel for the rear suspension continues. I still want to stuff those 14" bypasses in there, but each time I go to cut some metal, I get skeered. So the current set up will have to do.

During the process of rebuilding/valving the shocks, I remembered when I ordered these Tacoma spec smoothies, DSM and King were concerned about the 4Runner application. The longer shock would supposedly bring the drivers upper link in contact with the tank. So they put a billet 1/2" top out spacer in there to eliminate some ext length. The Califab upper links open up a little more droop and with the shorter FJ tank, I'm not even close to contact now.

Well I decided to remove the spacers and install some Limiting Straps.
McKenzie's for the win.

I also decided upon cycling the axle, that I could gain some more up travel. So I did about a 3/4" chop on my Metal Tech bump spacers. Now, in theory, I should gain about 1" of travel up and down, once the limit straps do their stretch. Hopefully this will help it keep up with the front now.

I did an initial drive on the street last night and I didn't realize how much the lack of valving in the smoothies were affecting the handling. It's much more stable at hwy speeds now with the new shims. Reservoir adjusters are wide open, so I have a lot more compression if I need it.

Awesome progress man ! More travel is always exciting. What all are you looking at having to chop out to fit the bypasses ? Regardless, I say go for it ! What’s the worst the can happen ? :) nothing that can’t be undone with a little metal and welding

Thanks, I think it may work a little better than it did with that little bit of travel. At least maybe improve the pogo stick syndrome. Hate that crap.
Now I'm going to be looking into weight distribution again to get my ride height where it should be.

I've got one of those new offroad jacks coming in this week I can put back there. Thinking about building a box for the jack and recovery gear, then the spare will live on top. I don't think a tire carrier/bumper would be happy with the violent abuse it will see in the whoops and I don't want that much weight, so I will stick with keeping it in the cab.

As far as the bypass? I learned my lesson with the LC rack. I suffer from monkey see-monkey do, and jump headlong into these projects I'm really not qualified to do. Both of these 4Runner builds have been an experiment in how far I can stretch my limited abilities and tool complement.
In the past seven years, I've spent a good amount of money just on tools alone.

From what I can tell with the bypasses, I don't have the down or the up to fully utilize 14" of travel, even if I could find a way to stuff them in there. Now that I have the FJ tank clearing the upper link and spring, the limiting factor is the lower links bottom out on the axle before the full droop of the 14" bypass can be attained. Then on the up travel, the custom track bar mount that came with this axle, tops out on the cross member. I might be able to cut it down an inch, and not upset tracking too much, but it's a gamble. I guess the cross member could be moved like DocME did on his FJ.

Instead of cutting into the cab, some guys have built hoops in the fender well to mount them, but most of them have longer axles (Tundra, Dana), so the lower mounts can go further outboard on the axle. Then you keep a good A-frame set up with the right angles and geometry.

The idea of cutting into the cab doesn't appeal to me for obvious reasons, but I will consider it if I can seal it up properly from exhaust and some of the noise.

One advantage of cutting into the cab that I do like, would be to mount a brace between the two towers. Then one between the two front towers and that would reduce some of the twist this frame sees in rough conditions.

All of this will hinge on figuring out a link system that will allow for that much travel. The lower link will not work in it's current configuration. But, that's why you do the mock up/cycle thing until your blue if the face. The other thing is making the coil springs work with that much travel. You have to capture them like CaliFab has done on his 3-Link.

CaliFabs 3 link might be the ticket, or the Dirt Designs that DocME has on his FJ.

The only other option I see with my current set up would be to capture the springs, reposition the lower link mounts on the axle to allow more droop, move the cross member to allow the track bar mount to clear on up travel, then cut the upper shock mounts into the cab and make it work, but most of this stuff is out of my skill set. I will have to work on getting better at using the online 4-link calculator for sure.
 
I certain suffer (probably even worse case than you ) from the monkey-see-monkey-do syndrome and diving head first, completely blind, into just about every project I've undertaken with the T4r, so I certainly feel you on that...

A couple of pricey/time consuming lessons I've had the misfortune of learning were:
-RCV Axles
-LC200 rack swap
-poor man's long travel rear setup

At the same time though, I definitely have learned a lot in the process.. just wish it wasn't at the expense of time and money involved :)


I see your predicament with using the factory axle.. that definitely is quite a limiting factor for sure... I'm assuming you're currently NOT looking to do a rear axle swap to something wider? Surely you're all fully setup to rear gear axles, set lash, etc at home right ?? ;)

But on a serious note though, I have seen a couple of cutting-into-the-cab projects and it depends on how intrusive you're getting. A lot of them were left pretty much wide open... which always baffled me... the noise, smell and debris while running offroad have to be insane.. I did see a couple of other that had the shock towers frenched into the frame and cut into the cabin that didn't take much effort at all to close up with some sheetmetal and a little weld time/seam sealer.

For me a route like that is a no-go since I use every inch of my interior space.. but for your build it could be quite a possibility.. just a little grinder time and some non-structural welds to button everything back up.
 
This came in today. Fit and finish is pretty good, we'll see how it holds up.

Whatever change Harbor Freight made internally over the past couple of years has really been working from them. Their product offerings have been pretty damn solid, and with these jacks in particular I know they knocked it out of the park with initial release... they have been selling like damn hot cakes with no stock anywhere around me (not that I necessarily need one... but it could be pretty handy vs my current standard jack for 4runner work).

did you order in store and have shipped to you?
The price point vs the pro-eagle is in line with what something like this should cost... I can't imagine spending $600 on a damn 3ton jack..
 
My old Daytona (23.5 " lift height) gave up last month, so I bought another one of those at 25% off and bought the Badland (preorder) the next day for the same 25% discount. So I got both of those Jack's for less than the pro eagle.
Even if built in America, $600 is freaking outrageous.

So I went and picked it up yesterday. Took a little over 2 weeks.

man.. that is a killer deal at 25% with the year-end coupon for sure! I'll probably do the same later this year as they become (hopefully) more available.

I think pro-eagle had a great strategy with being the only "off road jack" being marketed to overland/offroad folks who already drop outrages amounts of money on shtuff they rarely use (me, me, me! I'm one of those guys!) lol so they had a bunch of people buying them up. As you said, even made 100% in the US at $600 that's quite a healthy margin to be making on a floor jack.
 
Picked up a clunk in the right front I've been chasing for a couple of days. SMH.....out of patience so I'm gonna park this thing for awhile.
 
I feel your pain on that one man... you know my experience with clunks and how I feel about some of my noises....

Yea I thought about some of the diagnosis you've been through. So I've been trying to go down the list. Greased and retorqued several fasteners the other day and I took the caliper and rotor off today. I had forgotten the rattle springs, but the noise is still there. I'm almost certain it's the R1 pads causing the clunk. Hell the rotors are a little sloppy also.
I can kick the tire and make them rattle.
The suspension acts as a tuning fork, so it gets pretty noticeable in the cab


I also have a cyclical vibration up front when doing over 75. Seems a little less when in 4hi. Gonna have to disconnect the front drive shaft for the next step. Wondering about the mm spacers I installed for 200 rack, thinking I might have a pinion vibration. Could be the D-shaft out of balance a tad. Hoping it ain't the diff.....

The one encouraging thing is the suspension is gradually getting better. I beat it pretty good the other day and noticed the improvements. Still bottoming all four corners though lol.
 
my "clunk" was obviously traced down to something different (being the transfer case under load in 2hi) but I will say this... I still have suspicion that something with the FJ t-case is causing some extra vibrations that you typically wouldn't have...

in my case, the fact that I did the twin stick modification (by removing the block-out "pill" that allows independent fork movement between the hi/lo & 4wd/2wd isn't helping I don't think... I constantly feel the case "grabbing" at the front drive shaft even though theoretically it shouldn't be in 2wd.. you should be able to freely spin the front Driveshaft (with the wheels in the air) when in 2wd... and I definitely can't. I have confirmed a direct connection (albeit probably not a very secure on) between the front and rear drivesahft while in 2wd which means there is something shifting in the case causing the synchro to start meshing.


I am still planning to source a 100% stock FJ t-case that has the factory J-pattern shifter to swap in favor of my twin-stick setup.. this should put me back to "factory" spec on the t-case operation.


one thing that still would remain fundamentally different than in the stock fj setup is the fact that I'm not running an ADD front diff.

This obviously mean that I am constantly using the ring gear to back-drive the pinion gear... I'm no gear expert here.. but this is obviously different than the factory setup where the passenger side wheel is disconnected from the diff..which in theory obviously shouldn't back-drive the pinion gear but rather have all the rotation go into the spider gearset instead. I don't know if in reality there is still enough force to get the ring gear turning, and with it the driveshaft, but I bet if we stuck a camera under an FJ with a manual t-case in 2wd we wouldn't see the driveshaft spinning..

The fact that the driveshaft in mine constantly spins the front half of the t-case though it's in 2wd isn't really a concern except for maybe slightly expedited wear ..but I'm thinking this, along with the amount of backlash that is normal for the front diff to have, could potentially be the cause of some weird vibration/feel I have coming out of the front... I mean I was thinking I had grenaded my front diff until I opened it and was proven otherwise with some VERY good condition gears.. so who knows....

One thing I'll say is that pulling the front driveshaft alone may not prove anything since the vibration could be coming from the front diff spinning up and maybe loading/unloading the backlash on the pinion. When I was in TRUE 2wd with no front diff it felt significantly more agile and smooth while turning and driving around town.


This could also explain that it get better in 4hi since you are then back to driving the front diff with the t-case instead of the other way around. I would be curious to know if your front driveshaft couples up to the rear one when in 2wd under certain driving conditions.. but that would require you to pull both axles unfortunately.

That's why I haven't gotten overly concerned, because I remember your thought process regarding the diff.

Mine is also spinning all the time, and the centrifugal force of the spinning assembly would almost certainly create it's own varying harmonic.

The LT A-arms most likely amplify this vibration, so it's got a nice little path back and forth between the cv, a-arms, frame, diff, front DS and T-case.

This is why I was wondering about the front DS balancing. And although a long shot, I was also considering the slight pinion angle change with the MM spacers in there. But, the front rotating assembly with no load on it is most likely the culprit.
 
Cargo Box cont

As most of you know, securely fastening down the menagerie of crap we drag around can be daunting. Safety first, rattling noise second.
Here is my solution for the Badlands handle. I added a small block bored with a 1 3/8" hole saw for each piece and of course a bungee at the other end. This should work to keep the rattling at a minimum:

Cargo Box - One more

Well I think this thing will serve it's purpose. I elected to pass on a drawer for the open cargo space on the left. I don't really camp out of this thing much at all, so I don't need a galley.

To fully enclose that end and make it with easy access, I built a lid with some inserts to help secure it, along with some link and latches. I think the 3/8 eye bolts might over kill, but it's gonna take a beating.

I was able to cram a duffle w recovery ropes and straps and stuff it in the front of the box. I then discovered 3 pelicans/apache cases fit nicely for shackles and snatch block, hand tools and a few other things. The Jack is pretty snug in there as well.

I can still see out the back window, even with that big ass hunk of rubber back there.

Passenger side clunk

Trying to isolate a clunk on the front passenger side. The first clunk/thud is the one in question. In the cab the sound transmits through the control arms, so it's hard to know where the problem is. In the video it sounds like it's coming from the wheel, so maybe it's a loose fit on the retaining pins for the aftermarket brake pads? The rotors aren't the tightest fit either, but you would think with six lugs torqued at 85 ft lbs, they would be secure. Any opinions are welcome. The second rattle is from the rear suspension heims which is something that happens occasionally when it loads and unloads through the travel. Nature of the beast when using heims.

Hideous Roof Rack has been deleted and cheapest amazon headlights (w gobs of 3M 5200 goobers slopped all over the seams) installed. That and I got the ADV glass fitted pretty well and a couple coats of epoxy primer on them.

Never sprayed with air before and quickly realized a 1.4 spray tip is too small for this epoxy with out reducer to thin the mix. Came out a lot like bed liner if your looking for the secret sauce mix lol.
