Popping in front when taking off, or speeding up
Independant of whether or not the wheels are turned, I get popping noises when I hit the gas a little harder than normal to get some extra speed. They "feel" like they're coming from the differential up front, but I've had one bad axle replaced, and had the entire third-member, and pinion bearings replaced and the noise is still there.
Before I had the diff worked on, and after the axle was replaced, it bound up and popped very loudly as I turned the wheels right and backed up. When it did this, it actually shook the front end of the jeep up and down as I pulled out and it stopped popping.
It's a 95 GC, Full-Time 4WD. Over 100,000 miles.
Idea's? Viscous Coupler???
