Drive train weakness and rear vibration
Posted: Thu Aug 04, 2016 9:32 am
There was recently a thread on rear vibration but, as usual, the search function doesn`t. Any road up, as they say in Yorkshire, I, too, had an annoying zzzzzzzzzzzzzzzz last week but when lifting off the accelerator at over 70 mph. A check around the obvious, the diff. and the four bolts attaching the flanges on the diff. and the propshaft weren`t loose, but could be rotated. I`ve nipped them up and all is well.
But, my question is this; we hear about output shafts twisting or even breaking under load but, surely, the weakest point in the drivetrain would be these 4 bolts, wouldn`t it? especially if they`re not really tight and no longer clamping the 2 faces of the flanges really tightly together.

P.S. I`ll be renewing these high tensile bolts with spring washers, nyloc nuts, and Loctite, with Loctite on the faces of the flanges too.
