ok, and what are zerk fittings i know somebody mentioned it and i would like to know how they look and what should i do to them grease em ?

 

They are the little nipples on your ball Joint and various places around your steering.... they are grease points. You need a grease gun to service them.

 

Roate tires(record mileage and date). Also check spare tire. If you do not have a fullsize spare, consider taking the steps to get one.

 

good call i will indeed get a full spare, and i will get brand new tires as these are low no for the trac lock do i jack up the front or rear ?

 

Rear.

 

ooo good thing i asked i was thinking it be the rear but i was starting to second guess my self and was gona jack up the front. im happy i waited for an answer lol. thanks man.

 

Lol no problem.

 

well no trac lock in my jeep

 

Not too many came with it.

 

Actually brake fluid is good to flush after this age, especially with this miles. Brake fluid absorbs mositure very quickly, which in turn will lead to internal rusting, which will lead to serious brake problems. Plus its good to crack those bleaders everyonce and a while so they dont get siezed in.

Also I would make sure to replace plugs with COPPER CORE. There are to many people and shops that are replacing them with platinum, they thing more expensive = better. Not the case, copper is the best conductor of electricity, and these jeeps have finiky ignition systems.

One other thing, Not immediaty, but something to think about, replacing your upstream o2 sensor (helps with fuel milage and drivability.) and think about replacing crank sensor, they are common to go bad, make sure to replace with a factory sensor, not aftermarket.

 

ah okay, and yes i did replace them with copper ones

 

for the diffs can i put 75w90 in the back as well ? Or should it be 75w140

 

We always use 75 90 at the shop, now if u ltoe, and live in a high temp area, the thicker oil maybe better, just my opinion.

 

i dont think ima be towing much and i live in illinois so its not that hot around here. Think il just do 75w90 for both. Thanks.

 

one more thing how do i know what axles i got or i believe thats what this is:


181 FBI, 194 RBI, 8 1/4" API GL-5
181 FBI, 194 RBI (heavy duty or trailer tow use) Synthetic

so it looks like i wana use 75w90 api gl-5 ? Since it shows all the axles for it and only 2 for sythetic but how do i know which one i have ?
