Thanks and yes. Actually I had the diff. cover taken off today and re lubed to
check for damage. My repair shop says "replace the whole rear end"
At $2000-$2200
He says the cost to replace the gears and bearings is close to the whole replacement.
I am getting a second opp on it for sure.
Thanks for your help
