also have the shop check the tail housing bushing, that holds the yoke steady, and replace the output seal.
the driveline shop may use your old shaft as a donor for the weld on tube yokes for the ujoints but have them price it out with new stuff just so you know. it may be better to use the old yokes simply because a used shaft isn't gonna bring you much cash if you can sell it. maybe better to sacrifice the used shaft as a donor for the yokes. make sure to test drive it before you hand over any cash so you know it's right before you leave. I usually tell the shop that does work for me that if they didn't test drive it at highway speeds then don't call me yet to say it's ready to pick up. test drive, check for leaks after, then call me when it's complete.
