Thanks, I really appreciate that.
Funny you should ask about the brakes. See post #18 in this thread.
Lol, that's awesome, many thanks!

Granted this is a pretty easy job but I always appreciate having a how-to with pics and others may as well. Note: anyone preferring to buy these instead of DIY them can't go wrong with Rad Rubber Designs' 4th Gen product. I was tempted but I don't mind DIY stuff and really don't mind saving $40 over the cost of that product + shipping.
I found lots of great info including these two threads. Special thanks to [MENTION=104572]Slowgoat[/MENTION] for the original templates and [MENTION=113703]46runner[/MENTION] for the version that can be printed on letter-sized paper.
PDFs for 4th Gen Fender Liners
Plastic "Splash Guards" Missing...
These are installed in the front wheel wells only, and there are 4 total. Each side has a large one and a small one. Important: the two large ones are the same pattern while the smaller ones are side-specific, hence the markings "FL" and "FR."
The old ones were brittle, had some holes, and there was also a huge crack that happened when I removed the top fastener to get to the engine block coolant drain a few weeks ago. Can't really complain though, they've been hanging out in the wheel wells since the truck rolled off the line in September 2006 so they had a good run. ;-)
I had already removed the top right fastener when I remembered to take this pic.

I bought some pry tools I can use on other stuff ($4.99 at Northern Tool) and a set of hollow punch bits to do the holes ($7.19 after 20% off coupon at Harbor Freight). Neither are mandatory, just helpful in removing the fasteners and having clean holes.

Here are the paper templates after cutting and taping. The sheet at left shows what they should look like. I used a standard office-type punch to do the holes. It wouldn't work on the rubber though.

I used this 1/16th inch material from Amazon (thanks [MENTION=145671]BagiMT[/MENTION]). Using a sharpie to outline them works as you can see the shiny lines against the matte material.

One 2'x2' sheet was more than enough to make all 4 shields. I lined up the straight sides against each edge so there were two less cuts to make. It's hard to make out but the other large one is outlined in the empty area.

A good pair of scissors easily cuts the rubber material. Here are the shields before making the fastener holes...

...and after. The 1/4" hollow punch bit was perfect for the job. Use a wood block under the rubber. A brief squeeze on the drill trigger was all it took for each hole.

It was definitely time to replace these. They're the same size; the new one looks a little larger but it's the perspective.

I used the old fasteners and all but one cooperated. The last one broke on removal but fortunately I had some extras in my miscellaneous parts bin. These are the new ones installed on the passenger side. Installation tip: poke the fasteners through all the holes in the shields before placing the shields and pushing the fasteners into the corresponding holes in the wheel well.

That's it. Happy to answer any questions.
X-REAS Delete + New Suspension Install
I finally got the X-REAS swapped out and the difference in ride quality is night and day. Again, I thought it was still working as designed b/c the truck handled well and nothing was leaking, but the ride was pretty harsh. Much, much smoother now and it handles better too. Bonus: the new front springs added about 1.5" of height at the fenders and 2" at the front lower skid plate (right under the bumper) that leveled out the rake nicely even with the .25" the rear springs added.
Here's the new setup:
Bilstein 4600 shocks and front springs from a '15 Tacoma TRD Offroad ($130 from local Craigslist)
2007 FJ rear springs ($70 shipped from a FJ Cruiser forum)
Energy Suspension rear shock bushings (Model 9.8108G)
![]()
Parts are plug and play except for the rear shock bushings. Here's a thread about ways to change the bushings and my post showing how I did it.
Also needed a 22mm wrench to disconnect the X-REAS fittings at the appropriate place (not at the shock!) so that was $7 at Home Depot.
I bought new top mount nuts and lower bolts, washers, and nuts from Toyota for $42 including tax but returned it all as my original hardware all worked with the new gear.
Scrapped the old springs and shocks at a local yard and they gave me $4.20 for them. Woo!

Happy to answer any questions, and I also put together a set of PDFs from the Factory Service Manual that provide a lot of useful info including torque specs, directions for removal of the entire system or shocks only, and so on. As with anything, this is for reference only and it's your responsibility to use whatever is helpful to you in a safe manner. Here's what is included:

Disconnecting X-REAS
I couldn't get the 22mm wrench on the fitting and turn it without bending the wheel well wall in a bit. Just tighten down a crescent wrench all the way and gently bend it toward you, then slide the wrench down a bit and do the next little section until you have enough room. About a half-inch in was enough. When you're done, just gently bend it back. I had some black spray paint handy to cover any spots where the coating got scraped.

It's slow going to disconnect the fittings b/c you can only move the wrench a fraction of a turn each time. Here's one of the rear fittings with the wheel well bent out of the way and the fitting partially loosened. The pic is a bit deceiving as it looks like way more room than it is. Bracket at left is where the rear sway bar link attaches. It has to be removed to get to the fitting.

This one's off and I'm ready to remove the shock.

The bottom spring mount is designed such that you rotate the spring until the end runs up against a stop as shown. This is the old spring before removal.

After installing the new shock and wrangling the spring for a while, success!

The front X-REAS fitting is tougher to reach and is easier to confuse with the brake lines. Be sure to follow the tube from the shock to the fitting and be sure you have the right one.
![]()
The FSM disposal instructions say to remove the banjo bolt and drain the shocks. That was only possible for the rears b/c it took 5-6 extension/compression cycles to empty them and I couldn't budge the fronts with the old spring on them. The fluid was amber and remarkably clear. It's just a trickle in this pic since I didn't have enough hands to compress the shock and take the pic.

Old rear spring vs. new-to-me 2007 FJ spring. They're sitting upside down; when installed, the rounded end is on bottom and the flattened end is on top.

On to the next project!
I had my flaps in a corner for months. I was gonna try to use a Dremel and cut off wheel. Found my tin snips and was like what the hell. Worked perfect.Today I replaced the front & rear stock bump stops with SuperBumps. I’ll review the difference at some point and will also post on my ordering experience with Wheeler’s, which wasn’t good.

I also cut down my mud flaps and discovered two things: I like the look much better:

And I was overthinking the difficulty level of the mudflap delete mod. I traced the edge of the body with a Sharpie, removed the flaps, then got out my jigsaw, which didn’t work well. That’s when I remembered that trying the simplest option first is always smart. Turns out these snips will cut the plastic easily.

I saw you've got the z36 brake kit. I also clicked on the link to take me to your post about your 1 year 15k Mike review. So it's a little over a year since that post and I'm looking to order that kit this week. Got any sort of an update for me? As well as, did you do stainless steel brake lines?
A timely inquiry as I just replaced my Z36 pads a couple of weeks ago at 44K miles. See this post for an update.
Nice. Did you replace with the same parts or different? Also did you do the 319mm sized rotors or go with the bigger rotors? 2 years and 44k miles until the caliper seized again? Are you happy with that? Or is the 5th gen swap in your mind?
1. The only thing replaced this time were the brake pads, and yes, they were the same PowerStop Z36 pads.
2. My truck is a Sport Edition so it already has the larger 338mm rotors.
3. The calipers were fine when the brakes were done 44K miles ago. This was the first time I’ve had a caliper problem since buying the truck in 2014 with 96K on the odo.
4. I haven’t considered the 5th Gen swap because I’m happy with the 4th Gen Z36 kit on my truck.




Swapped in LCAs and coilovers from a 2020 Tacoma TRD Offroad to complete my latest suspension setup (installed 4Runner 4600s on the rear a couple of weeks ago).
![]()
Notes:
- Installing coilovers is (obviously) much easier with the LCA removed.
- Tacoma LCAs are plug and play on 4th Gen 4Runners.
- Steering is noticeably tighter with much less drift.
- Battery removal is not necessary to install the driver's side LCA. The clearance issue when sliding the long bolt forward comes down to fractions of an inch and involves 1) the bracket holding the cabling to the positive side of the battery and 2) the tray itself. Just remove the 10mm bolt holding the bracket and swing it out of the way as shown in the pic below. Then undo the battery hold-downs and lift the battery & tray just a smidge and it will clear.
- The FSM calls for a new castle nut and clip to attach the LCA to the knuckle. I debated this, figuring the old ones would almost certainly be fine. Found out I could get new nuts & clips for $6 at Cobb County Toyota and decided it was a good investment considering the consequences of a failure, however unlikely it might be.
- These LED lights are very handy. Note it hanging from the fender in the wheel well shot above. There's a magnet in the swingout hook so it can be attached in many places where good light is needed.

I think you mean UCAs.
UCA = Upper control arm
LCA = Lower control arm
I replaced my UCAs on Saturday with SPC adjustables. Less than 45 minutes per side for just the UCAs.
