1996 Yukon Vibration Problem
1996 GMC Yukon SLT 4WD 5.7L Vortec 350
Back Story: Last week my wife was driving the Yukon and the driveshaft dropped from the rear yoke. After having it towed home i found: 1. Driveshaft was removed and unmarked. 2. One broken bolt in the yoke and one loose bolt for the U-Joint strap.
At this point, I have removed the yoke, drilled out broken bolt, reinstalled with same exposed thread count on pinion shaft, replaced both U-Joints in driveshaft and reinstalled, just to get vehicle drivable again.
My current problem is a vibration at 40-50 mph. It seems to be a "lighter/softer" vibration now than when it first started.
Any insight, opinions or help would be appreciated. Thank you in advance
