Thanks for the info. I bought my jeep with 88000 miles i am at 89 now and have no records if the po ever did so I think its a good idea to do it now.
That is probably a good call. Most people do not change differential and transfer case fluids as it rarely if ever crosses their minds. The first thing I do when I buy a vehicle is to do all the maintenance because rarely are there records if it has been done.
2000 Sahara, 3.5" Rubicon Express Lift, 1" spring spacer & 1" Body Lift, 33" or 35" BFG Mud tires, Front & Rear ARB, Rancho 9000 shocks, UCF Ultra High Belly Up
That's almost every oil change, synthetic oil at 7500...
I do diffs at 50-60k especially with a vehicle that's does not drive their car truck hard, towing etc.
I used to do my sti at every 90k but that was highway and 30-40k miles a year
I though I had a Dana 30 and a Dana 35 just to make sure I contacted Jeep and asked for my build sheet. This is what I have.
DJJS DANA 30/186MM FRONT AXLE
DMEP 3.73 REAR AXLE RATIO
DRKP HEAVY DUTY DANA 44 REAR AXLE
I was surprised. I wanted to change my diff covers to ARB but they are a little expensive for me right now so I might just re use the ones I got.
