Strange Vibration

[Jon916996748]

I recently had my 80 serviced for a vibration problem at the dealer. It turned out that the U-joints were about to fall out. After I got the truck back, there was still a strange vibration at around 50mph. It doesn't occur at idle or when you rev. the engine. I think this might be the wheel bearings or the wheels themselves. My question is, how hard is a knuckle overhaul? I was looking at the MAF Knuckle Bearing kit. Thanks for the help.

they may have put the shafts together wrong.....

I'd take it back to them and make sure.

Vibrations that occur at about 50mph are usually tyre balance related. That said usually problems with a vehicle can be traced back to the last work done on the vehicle. I'd check the shaft alignment (phasing) first but then look at the wheel balance if the vibration persists.
