Guest ambitionz Posted February 26, 2013 Share Posted February 26, 2013 1994 TT supra 6speed about 89,000 miles When i am reversing the car would move back then i would hear a banging/knocking noise coming from the rear of car then the car wouldn't move at all. I'll prob jack up the car tomm since its my day off and give it a look, any ideas what could cause this? Quote Link to comment Share on other sites More sharing options...

Tyson Posted February 26, 2013 Share Posted February 26, 2013 Sounds diff related to me if it wouldn't move but my mechanical knowledge leaves a lot to be desired Quote Link to comment Share on other sites More sharing options...
stevie_b Posted February 26, 2013 Share Posted February 26, 2013 The subframe bolts, if they're not tight, can cause the car to make some unnerving clunks when manoeuvring slowly, especially reversing with the steering on full lock. However if your car won't move after you get a clunk, it's probably something else. I just pointed this out as it's something to eliminate from your search. What do you have to do to get the car moving again? e.g. if you drive forwards for a bit, does reverse then start working again (until you get another clunk)?

James Posted February 26, 2013 Share Posted February 26, 2013 The subframe bolts do indeed sound like the culprits as Stevie has mentioned above. If it was diff related, you'd find the same sort of thing happening when going forwards and turning also. I had such an issue with my diff and it turned out to be broken teeth which required a replacement. Though I had tightened the subframe bolts about a fortnight earlier so was a lot more confident in pinpointing the issue. In short - tighten up your subframe bolts as a first potential remedy Quote Link to comment Share on other sites More sharing options...

James Posted February 26, 2013 Share Posted February 26, 2013 Sub frames bolts wouldn't prevent the car from moving though. I seemed to overlook that bit. If it was the diff, the car would suffer the same sort of experience when moving forward also (especially when the wheels aren't straight). Unless it is simply to do with the reverse gear in the box itself? Quote Link to comment Share on other sites More sharing options...

Dnk Posted February 27, 2013 Share Posted February 27, 2013 (edited) Too actually stop the car from moving sounds very very bad in my opinion, i'd be getting it on a ramp and doing a serious inspection of the drive shaft cv joints and the diff. I'd be inclined to drain the diff oil into a clean container and see if its got any parts of the diff in it. Undo the filler plug before you drain it !
