Schiffy Posted September 19, 2013 Report Share Posted September 19, 2013 Ok, so I swapped out the rearend in the GT 2 weeks ago, haven't had any issues, then yesterday I was on my way home from work and a hard shift into 2nd, I noticed a "THUNK" sound in the right rear. Matt said check the shock, so today while I was messing with the exhaust, I checked all bolts and mounting points and didn't see anything out of the norm. It doesn't sound like it's coming from the actual rearend. Could it be the U joint? I thought if it was the u joint I would feel it more, but it honestly sounds like it's somewhere in the passenger rear somewhere. Could the bushings be shot and the jolt of the car learching fwd be the cause of the sound? I drive her hard and put her up wet, soooooo.... lol Link to comment Share on other sites More sharing options...
iRoush Posted September 19, 2013 Report Share Posted September 19, 2013 could be anything from the transmission to the rear end. I get a thud when I shift to the third, I've narrowed it down to the T45.. being well.... a T45 lol. Link to comment Share on other sites More sharing options...
Det_Riot Posted September 19, 2013 Report Share Posted September 19, 2013 Pull out your trunk trim and have someone watch the shock mounts while you drive. Could just not be tight Link to comment Share on other sites More sharing options...

joekd Posted September 20, 2013 Report Share Posted September 20, 2013 Is your car lowered? Could be your pinion snubber hitting. Sounds stupid but it was the cause of my rear end think (had brand new springs, shows and control arms so was easy to rule those out) Link to comment Share on other sites More sharing options...
GearGambler Posted September 20, 2013 Report Share Posted September 20, 2013 so you have control arms in the car? Im guessing you replaced the rear housing bushings with urethane ones while it was out of the car. sounds to me like a bushing could be blown out.

Just slapped them in and tightened them up. The snubber sounds like something to check. [MENTION=95]Forcefedhatch[/MENTION] told me to cut some off, and I completely forgot till just now. lol Link to comment Share on other sites More sharing options...
Forcefedhatch Posted September 20, 2013 Report Share Posted September 20, 2013 Yeah.. the axle housing bump stop.. or I just bought the bbk replacement for lowered cars.. like 20.00 from eBaySent via Galaxy S4 active.. Link to comment Share on other sites More sharing options...
SniveTroll Posted September 21, 2013 Report Share Posted September 21, 2013 did you adjust the adjustable uppers you bought to stock length? if not you may have the pinion angle off. Link to comment Share on other sites More sharing options...
Schiffy Posted September 21, 2013 Author Report Share Posted September 21, 2013 did you adjust the adjustable uppers you bought to stock length? if not you may have the pinion angle off.Yes, they are the same length as stock, also, if it had to do with the way I set the rear up, why did it wait almost 3 weeks to start making the noise?
