Front end thumping at low speed
My jeep has recently started making a thumping/banging sound in the front end. It's a repeating sound, and the faster the wheels are spinning, the faster the banging is. At first I thought it was a u-joint or the gears in the differential, but I'm no mechanic. Sounds something like that, though.
It likes to do it when I'm creeping through a parking lot either coasting, stopping, or on the gas very lightly. Only does it sometimes, seems like more often when it's warmed up, but I don't stop much until after its warmed up anyway...
I noticed it started right around the time I changed my front diff fluid. I was careful to keep it clean inside and put 75-90 in the first time with mopar friction modifier. Night before last I changed it again to 90-140 to see if that would quiet it down. No effect.
It's a |6 automatic with selectrac.
It's louder and more likely to happen if my sway bar is disconnected.
Pretty much all the bushings on the RE 4.5 lift are shot. Maybe that's it?
