I’ve got an issue with my passenger side CV Axle on a 1999 WJ with QD. I had it replaced at a local mechanic because of a torn boot. Went off-roading the next day and all was well until going up steep inclines under power, I heard a “clunk, clunk, clunk”at seemingly random, but frequent times. Usually at low speeds, but always under load. Took it back to the mechanic who said I needed shocks and ball joints. So I bit the bullet and replaced the ball joints and shocks myself and at the same time swapped in a passenger side axle from Autozone. All was just fine – on and off road – for about 500 miles. Now the clunk, clunk, clunk is back, but only at high speeds (above 60 mph) and under load, like passing. The clunk, clunk, clunk is about 2 to 4 timesa second. One more thing. Both CV joint boots (from my mechanic and fromAutoZone) touch the axle tube when turning. Also, I noticed the diff’s oil seal rides on the very edge of the polished area for the mechanic’s axle (I bet it does the same on the Autozone axle too).
Any idea what could be causing the clunk, clunk, clunk noise? Could this be a case of non-OEM axles not fitting my car? Or since I don’t know if my mechanic replaced the front diff gear oil or not, if the diff oil was added without friction modifies, could that cause the clunk, clunk, clunk noise? I’m at a loss what to do next. I hate just replacing parts.
