Goguvarra 0 Posted August 22, 2011 Report Share Posted August 22, 2011 Hello,My car makes a strange sound while in reverse. it's a deep thud and it comes after I have selected the gear because I know the gearboxes don't like it when you rush it in reverse quickly after moving forward.so...reverse selected, I take my foot of the clutch partially and sometimes I can hear a deep thudding sound, like something is locking in. I'm thinking it's the syncro system because it doesn't seem to come from the gearbox it's more from the back of the car and I can't imagine how a gearbox would make such a noise.Is it the viscous diff ? Should I worry ? thanks.could it be one of the diffs ? Is this bad ? Link to post Share on other sites
bungy 2 Posted August 22, 2011 Report Share Posted August 22, 2011 Will definately be worth checking your prop shaft for free play and the diff for backlash. Link to post Share on other sites
Goguvarra 0 Posted August 22, 2011 Author Report Share Posted August 22, 2011 ok...is this hard to do ? do i have to take down the exhaust or something ? do i have to take apart the diff or the shaft ? and why would this be heard only in reverse ? I also tried to make the rear wheels spin by taking of under hard throttle so the central diff would engage and I thought the car was really responsive with minimal tyre screeching, but the engine was all reved up so maybe I couldn't have heard the thudding if present ?

Goguvarra 0 Posted September 16, 2011 Author Report Share Posted September 16, 2011 so it is not while to shift the lever into reverse but while you drive in reverse that you sometimes hear this thud ? mine doesn't do it all the time. Link to post Share on other sites
