Hey guys
I went 430 miles on my break-in period of my new gear set with out any noises. Today ive noticed a whirring noise that im suspecting to be comming from the rear end. It might not be, but this is the most recent thing ive done. It seems to start around 5mph where its really really quiet, at 25mph its at its loudest; it sounds like the destist when he drills your teeth. But around 25 it seems to quiet down, its hard to tell the tires drown out the sound. Its not really a howling, but a high-pitched whirrling/grinding.
Facts.
its been 430 miles since the gear install, really close to changing the diff fluid.
My backlash was .008 at install...
My pinion bearing preload was 26inlbs +-1inlb...
Remaned M5R1 installed less then 1500 miles ago...
I havent drove more then 10 miles since its started happening so i probably havent destoryed anything yet. According to Randy's ring and pinion my pinion bearing pre-load might have loosend up, or this might be normal as the bearings wear in; i would need to tear it down to tell. any ideas?
