I know we have a lot of techs amongst us, so I have a fairly basic question. My wife has a 2002 Jeep Grand Cherokee Loredo 4X4 with select trac (meaning you shift it into either 4WD Partime or 4WD Fulltime) normal driving is rear wheel only.
I wanted to change the front axle fluid.
Can you guys tell me if I have to also put friction modifier in the front like in the rear differential.
sorry for the stupid question.
I just don't know if they have the friction clutches in the front.
I'm also experiencing some gear "clunk" when I put it into part-time 4WD, I think in this mode, its mostly rear wheel drive until the rear starts to slip, then the front wheels engage, my guess anyway.
long shot question, but, worth a shot.
also, any idea of the type of front axle oil that I need? I'm assuming its like 75 weight gear oil, but, I'll confirm at the dealership.
