gasha Posted October 9, 2002 Share Posted October 9, 2002 I havent inspected it closely yet, but I think I may have driveshaft/diff/propshaft problems as there is a really knocky grindy noise that comes from the rear end, but strangely only when the front wheels are on full lock or there abouts and it is really noticable if you are trying to push the car about. Anyone know what it might be or experienced this before??? Many Thanks Gareth - C7SSP Link to comment Share on other sites More sharing options...
JAG Posted October 9, 2002 Share Posted October 9, 2002 Never had the problem, but if it only occurs with full or near full lock on the front I would suggest that the problem lies within the Diff' JAG Link to comment Share on other sites More sharing options...
F355GTS Posted October 9, 2002 Share Posted October 9, 2002 Gasha It always did that when I had it!, it never sounded right to me and the previous owner had it stripped by RH Motorsport who found no problems. Mark Link to comment Share on other sites More sharing options...
Tonycaterham Posted October 9, 2002 Share Posted October 9, 2002 Gasha, If the car is fitted with a plate type LSD then these noises may well be perfectly normal. Tony Link to comment Share on other sites More sharing options...
wonkey eyed barmaid Posted October 9, 2002 Share Posted October 9, 2002 gasha, is your car fitted with an LSD? is it a live-axle? F355GTS seems to know the car, and Im sure would have suggested this, but refer to my recent thread "HELP nasty noises..." I have since found out that the diff in my live axle is knackered, and is needing replacement. never made any noises dependant on steering lock, but was definatley noticeable when pushing in the drive... do your noises increase in pitch/volume/frequency depending on roadspeed?

gasha Posted October 11, 2002 Author Share Posted October 11, 2002 Thanks for the responses so far. When the car is being driven the noise is unnoticeable it is only really when pushing it while steering. Pushing it while in a straight line is fine, no noise. It has a LSD but I'm not sure what type. Mark, any ideas as to what diff ratio C7SSP has?? is it a 4:11? Ta very much, Gareth Link to comment Share on other sites More sharing options...
F355GTS Posted October 11, 2002 Share Posted October 11, 2002 I was given to believe it's a 3:92 but don't quote me on that! Also I was advised that the LSD is a plate type Don't know why it should happen but it sounds more like a failing UJ in one of the drive shafts, IIRC it was possible to hear the noise when driving at ery low speeds when lock is applied Mark Link to comment Share on other sites More sharing options...
masha Posted October 14, 2002 Share Posted October 14, 2002 that's what I thought when driving it - UJs (expensive, ouch) noticeable at low speeds on lock, wouldn't hurt to replace all frame bushes initially. Gar, we'll get Earnie to take a look on the ramps, don't worry you'll get out on the road in a repaired 7 one of these days (you can borrow mine in the mean-time for the London-Brighton run and we'll have a look over the winter months).
