Driveline Refresh

[epdarks]

Hey guys,

Hoping you can assist with my driveline refresh project.

My symptoms: noticeable slack in the driveline when going on/off throttle. "clink" sound when shifting into D or R at a stop. When you get under the truck and shift into D or R, you can see the driveshafts twisting.

At this point I am unsure if I have stripping "splines" as many do. I know it will likely make sense to rebuild the front driveshaft with the longer splines, my concern is installing it... what's the final word on installing the extended driveshaft? PITA?

Do you guys recommend rebuilding/replacing the rear driveshaft "while I'm in there"? It seems like most of the sudden failures come from the front driveshaft (splines stripping). If the rear is likely OK, do I just replace the guibo and be done?

Parts I want to order:
front guibo 26117503159 77.39
nuts for front 07129904473 .98
rear guibo 26117511454 50.90
nuts for rear 26127536563 1.66
center mount 26121229726 71.70
rear driveshaft cv seal 26111229078 8.51
rear driveshaft grease 07551225051 this isnt avail



Do I need any more parts?
ie:
centering flange 26117507533
protection cap 26207503105

Anyone done this job recently? Please advise. Thank you!
