Rear drive shaft balancer
On my 2002 F350 C.C L.B. with 208,000 miles I was on my way home from a 3 hour road trip and after pulling out onto the freeway I noticed a slight vibration only between 45 to 55 mph. You could feel it in the seat of your pants and not in the steering wheel. This morning I crawled under the rear end of the truck to check carrier bearing and u joints etc. Everything looked good and then I noticed that the balancer that is on the shaft just forward of the rear u joint was on crooked. Looks like the rubber inside of the balancer has deteriorated and let the outer ring slip. I did a search and could not find anything exactly like that.
Anybody know if you could just cut that thing off and have the shaft rebalanced or is it time for a different drive shaft.
