BrandonsZ Posted October 19, 2005 Share Posted October 19, 2005 I just had the same symptom, there was a metalic thump when I accelerated or let off on the gas, like "Thump, thump", it was substantial because I felt it in my feet. So I checked the driveshaft bolts, the half shaft bolts, even re-tightened the rear bearings, but it turned out to be the differnetial mount to the flat mustashe bar, one nut was loose and the other wasn't torqued, so I torqued them and that fixed it.

nienberg.11 Posted October 22, 2005 Share Posted October 22, 2005 I once had some nasty sounding thumping on acceleration, and it turned out to just be my new muffler vibrating against my rear skirt. Quote Link to comment Share on other sites More sharing options...

Ed260Z Posted December 2, 2005 Share Posted December 2, 2005 I'd say it's the front diff mount. They will feel OK even if they are bad. You don't know they are bad until you feel the thump in the back. Quote Link to comment Share on other sites More sharing options...
