I have been a long time lurker and occasional poster but figured I finally have enough for a thread. This is my 1999 Toyota 4Runner SR5 4WD with the 3.4l V-6 and automatic transmission. This thread will serve as additional documentation beyond what I keep in spreadsheets and paperwork and hopefully help anyone else (and myself!) looking for answers to questions they have or burning up a couple of minutes at work. This truck is my DD and has to be as reliable as possible.
I got it about a year and a half ago, having previously owned a 1999 Tacoma
(same setup except with the 2nd gen supercharger). My family got bigger and the Tacoma wasn't big enough to haul us around. I got it from the second owner, a lady who purchased it as a Certified Pre-Owned vehicle. When I purchased it - it had about 177k miles on it - I am now a 195K.
The truck came with 265/70/16 Michelins (which I can't seem to wear at all), 4.30 gears and 99 Tall springs all around - stock. The tires are kinda funny - everyone thinks I have a slight lift installed now because the tires are so small. Mounted and inflated they are 29.5" in diameter. Plans for the future include a true 32" tire.

This is the earliest pic that I have - A couple of days I bought it, my fiance and I used it to help move into a new house.
In October, 2011 at 179,990 miles I did a number of upgrades and maintenance to it:
1. Changed the all the fluids, lubed everything, replaced the fuel filter,
2. Began an AutoRX treatment course for it
3. Did the 199mm TBU
4. Added a B&M transcooler and bypassed the stock cooler
5. Added a mount for my iphone and blitz interface unit for the factory radio
6. Installed a Scanguage in the ashtray area.
7. Added a K&N filter purchased from Ripcord (going very light on the oil prevents MAF clogging)
I followed a number of guides from the forum for the TBU and the transcooler - mostly from BigFishAllDay. Later in October I pulled the running boards (and sold them for way more than I thought I would - most people toss them) and added the SR5 flares order from Toyota of Dallas.

In that same month, my family and I were left stranded when the fuel pump went out - about 200 miles after changing the fuel filter. After doing a bit of research, I don't think that this is totally uncommon for 4runners that don't have the fuel filters changed on a regular basis. I was very busy with work at the time and had a local shop replace the pump. I like to wrench on my vehicles but just didn't have the time to pull this off.
For the next year, I have driven and just enjoyed it. It ran great, got a consistent 20-24 MPG and had more than enough room for the family and puppy and the occasional camping/hunting trip. I had a small fender bender in May, 2012 where a nice lady in a Kia stopped in front of me. My bumper was toast and I replaced with an ebay bumper - cheap and fits alright. Every time I changed the oil, I used a Toyota filter (buying in bulk) and lubed all of the points on the driveshaft. Even though it is kinda messy, I would rather do it myself than pay someone - mostly because I can't inspect the underside of the truck if someone else does it.
