yeah i'm getting 3 spicer u joints and the spicer centering ball kit. i checked out all the parts before he started doing the work. Are the rear shafts as likely to fail as the fronts? should I look at doing the rear next? Thanks Mike.

 

The rear shaft is fine. Just make sure you keep an eye out for the roto-flex coupling. When it cracks and vibrates, you'll need to replace it.

 

How often do you grease your grease fittings? Should be at least twice a year, if not go replace the rear u-joint also and watch for cracks between the 6 bolts on the rotoflex.
Also remove the plugs on both shafts, insert a grease fitting and lube both slip shafts also, then replace the plugs.

 

rebuilt front drive shaft reinstalled. clicking and squaking gone. thank you all!!!
