My F-Type has OE LSD installed, however it did not come that way from the factory. I am not entirely sure that is even causing my issue. The "symptom" only occurs when you really get on it in the lower gears, tends to happen when youd expect the wheels to spin or break traction (I need to see if it still happens in the various stability control settings), you can feel it in the rear end, and it lets out a very quiet rumble. Other than these rare instances, all is quiet and well. The car also has lowering springs. Im wondering if yall think its driveline or suspension related... and if i should even be worried about it.

 

Anyone have any ideas? You can feel something spinning / knocking / rumbling in the rear. As if something is either making contact or slipping due to too much load. It only seems to do it when the rear end comes down under heavy acceleration. I also noticed it when going over a slight hill / bump, as the weight of the car came down you could feel it as well.

 

Get it on a lift or otherwise up high enough to slide under and look for wear marks on the driveshaft and on the halfshafts.

 

Also check out the lowering springs to ensure that they are sitting properly and the rubber isolators are still in place.
