Noob here, I bought a truck. 1992 4WD 'deluxe' pick up.

I'm a noob. Never had a toyota truck, nor a 4WD truck.


I want to swap out all the fluids - but I'm getting confused about what I'm supposed to use. What is ADD and how can I tell if I have it? How can I identify which transmission I have? What kind of oil do I use on the 'propeller' shafts?


High miles - 230k. It was rebuilt at 170. Would it be a bad or a good idea to use synthetic or synthetic blend oil?


Any help would be appreciated. I got online to order fluids and I'm just lost. Also, where can i buy parts for this truck over the internet?

I'm assuming that the "ADD" you mentioned was stamped onto the dipstick when you checked it. That just means that if the fluid leven drops down to that line, to "add" more of that fluid to raise the level upto the upper line. As far as identifying the transmission, if it's an auto, use auto trans fluid (ATF). It should be able to use any dexron III or better fluid. If it's a manual, use manual trans fluid (gear oil). The propeller shafts just need grease in the u-joints. It's a good idea to switch to full synthetic fluids, but thats up to you. Standard fluids will work fine. If this doesn't clear things up, buy a repair manual for your truck. It will be your best friend for those little repairs, tune-ups, and adjustments that you don't want to pay to have done.


Try looking at autopartsway.ca, this is where i ordered most of my spare parts.

Btw thanks for the advice!

ADD is "Automatic Differential Disconnect" it is a vaccum operated system that unlocks half the front axle. You can shift into/out of 4wd with this feature. it replaces the manual or automatic hubs with drive flanges. Manual hubs and ADD are good, auto hubs are bad.
Tranny? auto or 5spd? v6 or i4?
Also, 4x4wire.com is your friend, best bunch of toyota forums on the web.
