interesting. My room mate's jeep does the same thing, and it makes a nice knocking sound from underneath when he floors it. I cant stand listening to it when he puts it in drive. CLUNK!

Ill have to look at his U-joints. He was run off the road a while back and had 4,000 damage fixed on underside his jeep, and ever since then its been doing that. from what I understand, the shop used many used parts to fix it, although he was billed for new ones.

just goes to show you that you cant trust everyone.
