clunk clunk under acceleration (atlas problem?)
my tj has developed an odd clunk clunk clunk when I'm accelerating. the u-joints ALL look good and I have locking hubs on the front. the lockers are ARB's ad are certianly disenguaged. the suspension is a RE long arm kit ad I have driven it about 5000 miles on the road and about 80 hours on the trail. the tranny is an nv4500 and the transfer case is an atlas II. both the tranny and t-case were new from advanced adapters 5500 miles ago. on my last trip to go wheeling, I noticed the case was getting hot, I looked at the sight tube on the atlas and saw it was a bit low, so I dumped a quart of gear lube in it. the case ran a lot cooler then.... I wheeled the jeep for 4 days and drove it 5 hours home. a week later I develop this strange clunk, i can even feel it a bit and its only when I'm on the gas.
1. think i burned something up in the atla$$$$$$$?
2. could a bad cv joint in the rear driveshaft cause this?
3. anyone ever been inside an atlas?? is it like any other gear driven case?
need to get this diagnosed soon... dixie run is looming...
