I have a '96 F350. We pull a 5th wheel weighing around 13,000 lbs.
Near the East Coast, we had a pinion seal replaced. The seal alone, no other parts.
By the time we reached the West Coast, we head a whining noise in rear end. A Ford truck repair service found bearing races tornup.
Their comment was the crush sleeve should have been replaced with the new pinion seal. The truck dealer found minimal lash and almost zero yoke drag. An expensive repair followed.
The East coast repair facility said if the crush sleeve was a factor, the rear end would have failed long before reaching the West coast.
Thanks for the input on the rear end. The pinion seal was replaced when we noticed oil slinging underneath. It was caught before it got too low.
What I'm trying to figure out is if by replacing the pinion seal with a new crush sleeve, can that cause the lash to tighten up and burn up the bearings?
