This is the first project I've completed at school! Don't worry, I'm still working on the welding project too, it just takes a bit longer to get everything setup. I've been doing a lot of homework recently, and just wanted to do something quick this weekend as a break. The steering never felt excessivly tight or binding, I just wanted something to do. Here is the apartment setup:


Here are a few before shots of the PS fluid. My guess is the fluid is actual PS fluid and not the required ATF, it didn't smell like ATF and was pretty dark. I will be replacing it with Valvoline Maxlife Synthetic ATF, which meets the Dextron spec.


I used the little pump from a soap dispenser to remove as much old fluid as I could before adding the new fluid. The old stuff looks kinda red in this picture, but that must have been the lighting, it was pretty brownish yellow as seen in the next pictures.


When the fluid first came out, there was some grody whiteish fluid that initially came out of the reservoir. I didn't get any good pictures of it on the way out, but when pouring into a waste oil container, I snapped these after seeing some of the nastiness flow into the container. Unfortunately, most of what I am talking about already fell into the container.


I capped the PS return line with this little cap piece I whipped up. The return from the rack was then mated with a 3/8" splice barb to some 3/8" ID tubing down to an oil collection container. I ran the tubing through an opening in the radiator support and down between the bumper and radiator. Seems the theme of this project was not getting enough pictures, because I don't have any of the tube routing. Normally I overtake on pictures, but I guess I was wanting to get back to the homework grind today. it sucks having 4 assignments due after a 3 day weekend.


I jacked the front wheels off the ground, set the key to the on position, and filled the reservoir up as I turned the wheels. Seems lock to lock 2 times was enough to drain the reservoir completely, but I did every lock to lock just in case. I used about 2qts of the AFT. When I was done, disconnected my drain system and pushed the return hose back onto the reservoir. After cleaning out the soap dispenser, I pumped the fluid down to just under the Cold Max line.


I also figured a power steering flush wasn't much good without a lube of the steering U-Joint. Its pretty crusty and probably bottle-necking the steering feel, but as I mentioned, the steering isn't really bad and/or stiff. I used some spray white lithium grease, since its what I had on hand, and turned the wheel to several positions while spraying.

As many of us know, the A/C drain is not in an ideal location. It just drips on the frame and causes it to rust. A few weeks ago I got everything needle scaled down to bare metal, but never got time to paint it up.

Cleaning the Frame
Today, I wire wheeled and brushed the areas again to get it down to paintable metal. Thankfully there wasn't much to do, since working conditions at school are not as ideal as at home. Didn't get a good before picture today, accidentally started spraying first. I've included the one from needle scaling a few weeks ago.


After painting, it looks really good. There are some areas that got a tad pitted from the 15 years of abuse, but I'm not really worried about it.


Relocating the Drain
A 3/8" splice barb fits perfectly into the A/C drain hose. This was actually the same one I used to connect to the PS return, I just cleaned it out lol. I connected some extra 3/8" vinyl tubing from the power steering flush with the barb, and zip tied it in two spots to the frame. I'm missing a splash guard, so didn't have clearance issues with that. It also clears the tire without issue, probably because I'm still on 265/65r17s lol



A Few Random Updates
06+ Headlight Upgrade
I have all the parts, just waiting on the bulbs to show up. For some reason they have really slow shipping on Amazon and should be here 9/17. I also bought an LED interior light set and some brighter white LED reverse lights so I can actually see backing up.

4th Gen Maintenance Tutorials, Writeups, and Picture Threads
Just before school started and not many people had moved in yet, I was getting bored. I had the welding project to do on nice days, but it was getting kinda rainy. I have saved a few writeups in my bookmarks, and wanted to share them with everyone else. There was a similar thread stickied at one point, but it got unstickied at one point. I created this thread: 4th Gen Maintenance Tutorials, Writeups, and Picture Threads with an organization system to hopefully make finding information easier. It got a lot of likes, but unfortunately not a lot of general attention, so I fear it may die lol and no one will see it looking for maintenance help.

Job Fair: Toyota Racing Development
My school is hosting its annual (virtual) job fair for interships, and Toyota Racing Development has purchased a (virtual) booth. In the past, this was all in person, so I was planning to show printouts of my writeups and documented experiences as an end used of Toyota engineered products. Since this is virtual, not entirely sure how the process is going to work. Thankfully, a PDF resume can have hyperlinks to places like this forum, and I can link all of my work. Hopefully my previous internship experiences combined with my passion for learning and helping others will help me to be a good candidate!

edit: The TRD recruiters unforunatelty were lame HR reps that didn't seem to understand my interests in 4runners

I probably need to do the steering flush. At 156k and no clue if it's ever been done. I got the rig around 90k with no Toyota records. Seems whoever owned it did it at an independent shop because I found oil change stickers inside the door jamb, which was odd. Haven't encountered anything that seemed bad or neglected so I got lucky so far.

Now that you mentioned it, I looked at the Toyota Owners site and the PS flush at 108k was one of 4 times its been to the dealer for maintenance lol. So unless another flush was done independently, that means that the old fluid was just really gross ATF. That particular time at the dealer was the "vital fluid analysis", so it got PS exchange, Trans flush (not exchange, but everything is going okay), diffs, tcase, throttle body cleaning, and spark plugs. Pretty sure I'm the third owner, and the POs did an okay job with upkeep. I'm documenting everything it has done, both at a shop and in my driveway, in a binder with receipts and details on the service completed.

Now spill the beans on the welding project!!! Bike rack? Tire carrier?

Its top secret for now lol, but you're on the right track. It will be able to hold a tire of some sort, but it is neither a bike tire or a car tire.

I thought I was going to be able to finish it this weekend, but I ended up with 4 homework assignments due Tuesday. I did some work on it Saturday though, so its still coming along. Since I don't have a really good place to work, I have to drag my welding stuff outside and back when I work on it, which takes a while. I did the flush since it was quickish and I needed to break up the desk time. Hybrid online school sucks :(

I'll be looking out to see what it is. You have my curiosity.

Good write up. I highly recommend checking the PS hoses coming off the reservoir while you are at it. When I first got my 4R, I found that all the PS hoses attached to the reservoir were rock hard. That leads to leaks and other potential issues. I've since replaced all those hoses except the HP lines on the rack.

Good advice, I guess I only "checked" the return since I had it off. It felt nice and plyable, but shed a lot of black debris on my hand while trying to get it off the reservoir barb. I'll try and get back under there this weekend and check them all out, thanks!

Yeah, my return line was leaking when I got the truck, huge mess at the reservoir from that. Then I found the large feed line from reservoir to pump was also rock hard so had to replace that. And if you follow the return line from the reservoir, it runs into a hard line and then back to a rubber line just behind the passenger headlight. THAT was also hard. Follow the hard line across the radiator to the driver side and it goes back to rubber line again. Also hard. So they all got replaced when I installed the aftermarket trans cooler and made the OEM trans cooler the power steering cooler.

Thanks for the system overview, I'll get in there and follow all the lines! A trans cooler is on my to-do list also, I like the power steering cooler too
 
Relocating the Drain
A 3/8" splice barb fits perfectly into the A/C drain hose. This was actually the same one I used to connect to the PS return, I just cleaned it out lol.

Oooo, good idea! I always hated where the AC drained (even though I don't live in rustville). I still have my barb from the PS/transmission fluid flush, I should put it back to work (although I do have the RadRubber splashguard replacements)!

Yeah, its definitely odd that it just spits on the frame like that. Can't imagine why I wasn't designed to drain somewhere that makes sense. Thankfully it doesn't really snow a whole lot where I live in Virginia, but this 4runner came from Pennsylvania. Its got some residual crusties from its life up there, and I didn't really know to look out for that kinda of stuff when I was 16 and bought it.

I can't take complete credit for the idea, it came from Extending your A/C drain tube (to help prevent frame rust) by [MENTION=114846]Bluesky 07[/MENTION]. I routed mine slightly differently, but his fit through the splash guards.

I just barbed the line and followed the frame until it poked out behind the splashguard and pulled it down - used the same lower zip tie point in your pic, thanks!

PS - I kinda wanna clean the evap now because of that thread, but I don't really have any weird smells/blockages.

Sweet! My A/C has recently gotten low on freon, which makes me worried about the evap core now lol. Gotta poke a bit and see if any dye is coming from the drain or anywhere near the compressor.
 
Tires!
I finally got some tires to mount on the free FJ Cruiser/Early 5th gen trail wheels (See here for more info in picking up the wheels). Picked up some 265/70r17 Falken Wildpeak AT3Ws lightly used on Facebook Marketplace to replace my current tires. I'm still on the stock suspension, so anything bigger would probably run into issues. I bought them off a pavement princess 5th gen owner that changed them out for something else. Hopefully thats not a bad sign haha. The Falken's have a date code of 5219, so they're just about 9 months old now. I'm pretty satisfied and they still have the little fingers on the side too! I'll be getting them mounted soon, and will update with pictures!


Old Tire Info
Just some interesting information on the old Wild Country Sport XHT tires. They were on the 4runner when I bought it in 2016, the date code is sometime in earlyish 2015, and I found on old Goodyear receipt from 186,411 miles dated 7/30/16 with a tread depth of 10/32. They currently have 3-4/32 on them. After some googling, the original tread depth was around 12/32, so with 211,800ish miles at the moment, these tires only lasted probably 30,00ish miles. Definitely not the highest quality tire, both in terms of tread wear and traction, but they worked for the 4 years I've had them.

06+ Headlight Update
Headlight bulbs are delayed in shipping. I recently learned from a local subreddit that Amazon is no longer routing through a UPS distribution center in my area, so things are going to take 2 weeks even when using prime shipping.

Welding Project and Dirtbike Excuses
To continue to tease [MENTION=109843]montijo505[/MENTION], I didn't get to make any progress on my welding project this weekend. It was sprinkling on and off most of Saturday, which is not necessarily good for welding outside. Heres a weld that I thought looked good as more teaser material. Its a piece of 1/8" plate welded to 2" square tubing to make it thicker for threads. The 1" square is bolted with a flange to the main contraption. Also a bracket I made to hold something round, I'm definitely learning that small things are difficult to make.


Instead, my friend and I worked on our dirtbikes. Its not necessarily 4runner related, but I figure I better provide a good excuse for not working on my welding project. I unfortunately didn't get any pictures of this weekend's bike wrenching, so I attached some older ones for viewing enjoyment. My bike is an Honda xr200r that I bought during an internship where I was away from family and friends and bored after work. It was kind of abused by the previous owner, so it made for a good project. I've already done a top end rebuild with new valves, cylinder bored +0.5mm, and new Weisco 65.5mm piston. All of this was done on a coffee table in a different apartment with the bike on the second floor lol. I did get the full security deposit back too! Its been sitting kind of sitting recently, and last had ethanol gas in the tank. This weekend we cleaned the carb out really well, drained the tank, filled with fresh ethanol free gas, and its back up and well! My friends has a Kawasaki KLR250 project dual sport and we cleaned the carb, replaced the main jet, replaced the main jet again, then installed a new stater.

The welding project is not a dirt bike carrier either lol. I already have the Aluminum HF carrier, and it works great! Although I would eventually like to make a raising and lower mechanism, since it is hard to unload by myself.

Heres a picture from a few months ago, I have the seat and plastics, they're just not attached here. Also an older picture of tearing down the top end from the rebuild.

You're gonna love the Falkens, they're awesome. Guess I'll have to wait on the other project....

I just bought a Hi Lift so need to weld something up to attach to my tire carrier. Rigd makes one but it costs like three times more than my jack lol.

Thats good to hear! I saw the hi lift, that was a good deal! Certainly cheaper to fabricate something, I'll be interested to see what you make!

Did you get the wheels powder coated? Or is that a secret too?

No, they're probably not going to get powder coated. It would be really cool, but I think I'd rather put that money towards something more functional like the tires, headlights, lift, etc. Maybe one day!

Find someone who won't charge an arm and a leg for sandblasting and then rattle can them! Jk they'll look good as is I'm sure.
