Octanejunkie's T4R project - 99 SR5 4WD 5-speed

I'm running 1st gen manual Tacoma axles. They appear to have ORS silicone boots installed ala extended inner boot mod.

I have manual hubs so my CVs don't turn when my hubs are unlocked, which is most of the time.

Ah, seems like manual hubs are about the best easy to protect our CVs when things are lifted.

Initial impressions of the 861's?

Thank God I still clear the overhead pipes in my garage!

Other than that, they feel fine on the street. I'm expecting they will sag some, especially after I add the aux tank. I'll have them off road next week.

You probably want to move that tailpipe hanger to mount off the frame, not the body - the rest of the exhaust mounts on the frame.

It's all on rubber mounts, I don't think the body moves enough for it to be a problem. I think the tailpipe is just about as likely to get crushed against a ledge in that position, though.

What are your plans for an aux tank? I chopped out that spare tire crossmember to open up space in that area. And if the dang exhaust didn't run through that side I'd have been able to squeeze in a wider tank and haul more fuel instead of the 15 (works out to 13.5-ish in real use) gallon tank I used that gives the exhaust plenty of room.

I think I still need to go back under there and heatwrap the exhaust pipe there, I was having some issues with fuel vapor pressure on this summer's trip. The weather was hotter than normal out in Moab (100+, probably above 110 one day) and it was making a lot of fuel vapor, and it would leak a little fuel out of the filler when I'd get the truck tilted enough. So I kept the main tank as full as I could, to keep the fuel in the aux tank as low as I could.

Eh, I saw interference issues between my front bumper and body from the factory... This is a Raptor, but this'll illustrate what the body can do compared to the frame when doing hard work offroad:

The 4Runner rear OEM mounts are very soft, but even the upgraded poly mounts will allow some movement.

I am on poly mounts but I can change that easily enough

I was thinking about trimming the tailpipe some, as well as wrapping that last section and fabricating/ installing a sheet metal heat shield between the tailpipe and tank area.

Regarding the aux tank, I decided on a Tanks Inc 51CPS poly tank

1949-52 Chevy Poly Fuel Tank

The overall size is 28" x 20" x 8-1/2" which will fit easily in the space behind the bumper without cutting the tow bars. I'm okay with 13.5 gal usable volume in addition to the stock tank...

Christmas Eve 2022

Dishpan Springs trail 3N34

We researched the route and conditions and decided to run the trail in reverse starting at the top of 3N16 and Green Valley Road at 6240'

The top of the trail was snowy and muddy, and in some spots icy. I didn't take any pics from the top form, but when we got to the 3N34 junction we stopped in the sun, most all snow was gone

Where we came from, 3N16

We took 3N34 towards Crab Flats, the trail starts out easy

We took that about a mile, weaving around seasonal campsites that were all closed until we got to the difficult section of 3N34 to Deep Creek just after passing this sign

It became challenging rather quickly after passing over the upper bridge (there is on at the bottom, too)

Since we ran the trail in reverse, we actually encountered the obstacles differently than most, and we went down them. With gravity on your side you'd think that was easier, and it is, but it's also easier to get out of shape quickly, especially with the icy patches we found, but it was fun!

Lots of banked and rutted trail, and many tight turns. Many were lined with brush jutting out into the trail, amazing pinstripe opportunity. I got many, I'm sure.

Lots of pinch points to navigate through

Many were off camber, some were icy. At 15 psi I was able to hold most of my lines with little slippage

We didn't get pics of the lower gatekeeper, we didn't want to lose light, we spent almost 4 hours on trail and never saw another person, but we did see fresh tracks, mostly dirt bike, but we did manage to have lunch on trail with a view of the lake

All in all, there were maybe 6 significant obstacles with several sections to each of them. Mostly rocky, off camber and very tight with lots of pinch points and opportunities for damage.

The damage
Aside from scrapes to the skids and sliders, this is the worst of it

This last one pinched the lower corner of the fender up, crushing the front corner of the rocker and pinch weld, binding with the fender with the door. It also destroyed my 3D printed mudflap.

I will have some repair and painting to do next weekend

All in all it was a successful day and again the truck exceeded my expectations in both capability and performance. This was a very difficult trail and my gf was not happy with the sheet number of obstacles - she's more of a green dot/blue square gal, no so much the black diamond type.

Treated the truck to a Morrflate 4-wheel air up

The trail is fully documented on All Trails and was a pretty basic run, couple of short steep climbs and descents, a few tight sections with hairpin turns and pinch points - nothing a 4runner can't do.

Went with a couple of guys from the Off Road Rookies group on FB: Alex in a 97 LC80, Felix in some sort of jeep.

It was a fun run, typical high desert terrain, best done between December and May to avoid the heat and dust. I'm glad we didn't have to pay the $15 per vehicle day use fee - federal holiday and all.

Not sure I would go back (for a fee) but it was good to start out the year grinding metal on rocks.

Weekend update: 254,072 miles

Did a "snow run" with two local groups, 4runner_Krew and Cali Yotas, up in the Big Bear area. About 60 trucks all tolled, needless to say, it was a long day.

We met in Redlands and took the 38 up to 1N09 then dropped in. Lots of mud and wet conditions along the route, no real snow till the end, above 6,500 feet.

With that many trucks, and varying driver skill levels and builds, from stock to fully built, not too much technical terrain was had, but some great views were.

Looks like a good day was had! I've done a snow run once, but we camped the night before. 3/10, probably wouldn't recommend, lol.
 
Weekend Update 254,095

Was taking the rig out to Indio, CA for the weekend when I discovered a coolant leak after loading up my gf's gear... change of plans; left my truck home and piled in her friends Range Rover (which I got to drive).


Driving my truck home from her house today the coolant temp hadn't risen above 188.6° while driving (torque pro) and gets as high as 195° after parking. It only leaks after being parked and it's losing very little coolant, for now, but I think a water pump and timing belt replacement (plus all included goodies) will need to happen sooner than later. started preparing.

Watched Tim's video, again:
Toyota Timing Belt Replacement (PART 1) for 3.4L V6 5VZ-FE (4runner, Tacoma, Tundra & T100) - YouTube

Ordered some stuff:
