Isnt the rumbling a common diff issue?

Carl Bourbon

I had a rumbling from the rear end once (3 times same corner actually)
Turns out it was wheel bearing, kept going after I replaced the bearing until I realised the hub which the inner race of the bearing fits onto was worn causing the bearing to fail prematurely (every 3-4 months)

I didn't like the price of a new hub so I carefully welded a layer onto the worn parts and stuck the hub in a lathe, turned it to correct size and it's been great since (2 years)

It could well be you wheel bearing(check the hub surface too)
If tightening your nuts(lol) doesn't work have a little look in this area

These jokes write themselves A sharp ruby can make my rear end rumble......

Seriously, as Tozer said, 200+ lb ft will see an 'unfixed' hub nut roughly back where it was, then 60° past that and jobs a goodun. Use a good breaker bar/socket combo too or you'll break summit!

And as as far as I know, you'll need to have the wheels on the car, on the ground, and in gear. The amount of torque required to get that extra 60-degrees on the nuts is more than the parking brake can hold.
