The other night, I helped my friend swap out the two universal joints on the rear drive shaft of his 1986 GMC Jimmy (full size). He said it was getting a little bit scary drive. That means a lot coming from him because he has been known to blissfully drive vehicles that others fear to sit in, never mind take the helm of. His last few jaunts to work and back were full of brain numbing vibrations that made the world around him appear to be a blur.
We removed the drive shaft after feeling the sloppiness in it, and we were both confident that there was going to be a serious lack of needle bearings inside. We were not disappointed. When we knocked the u-joint out of the yoke, there were no bearings left in one of the caps. Very niiiice. Where the bearings once lived, sat a pile of the finest metal dust that destruction can provide. A few laughs were had, the new universal joints slid right in, and the big honkin’ GMC Jimmy lives again.
