So, I started hearing a whining and low roar from my rear end about a week or so ago.  Not saying that it wasn’t already there but when someone points it out to you, it is all you can think about.  Unfortunately I am also getting some rough and tumble when reversing when accel is applied.  Couple times there has been a pop to the rear when turning while reversing as well.  So it sounds like it is due both a gear change and some carrier bearings.  Not something I really want to invest into the GM 10 Bolt.  I am hoping that they will both hold up until I have enough cash for a Strange S60.  But no holding my breath as it will take a while to save up for something like that.
