Need help on a 97 expy

[dustrag73]

My expy started having a slight vibration at 60mph. I dropped the drive shaft and noticed the bronze bushing in the trans/ transfercase stuck on the drive shaft yolk. Whats involved in repairing this? Its the rear driveshaft and my expy 4wd

When did the vibration start? Are you feeling it through steering wheel? Is their anything you or mechanic did to start problem. Read vibration at 70mph. In other post here. When was last tune up? Plugs, cop wires? Any dtc codes with scanner?

You should remove the stuck bushing from the yoke using a suitable puller. Install a new one after. That's the one causing the vibration -coming from driveshaft imbalance.
