Engine/Transmission (1998.5 - 2002) Service on front and rear differential?

[MFranz]

What oil are you using in your differential?How much was it and how often do you change it. I have a 4x4 and getting ready to do the service on both. Is anyone using the same weight on the front and back?



Thanks,Mike

I use 90wt in the front and the rear and change it about every 20,000 miles. I have over 326,000 on it so far with no differential problems and that is with quite a bit of towing and snow plowing.

Quick tip... dont fill til fluid coming out. Chrysler says half to three quarters of an inch below fill plug... . otherwise seals will start leaking due to psi build up.
