hard take-off causes \"CLUNK\"

I have a stock 81 cj7, I-6, 4 speed manual tranny. I have taken off kind of quickly a few times here lately and I hear a loud "clunk" sound that I think is coming from the rear end. I'm not taking off hard enough to bark the tires but harder than normal. Anyone have a clue about this? Thanks for any input

it's bent, patched, and wanders, but we love it.....

Re: hard take-off causes \"CLUNK\"

Welcome to the vast fraternity of those that have spun a 2 piece hub/axle. Sounds like time for some quality one piecers. It will let go completely in a short time if you dont do something. Retorquing the big nut on the end of the axle to 250 ft. lbs. may help.

Could it maybe be bad U-Joints too?

I had a loud sound coming from the rear end on an early bronco when I launched quick, ended up being an axle wrap problem.

It could be the 2 piece axle, but I would check your rear u-joints first. A bad rear u-joint is the most likely cause when you hear the clunk ot ting sound when you first take off.
