Drive Shaft and Pinion Seal Replacement | 1994 Chevy K1500

In this video, I remove the rear drive shaft, yoke, and pinion seal on my '94 Chevy K1500 Silverado truck. I replace the pinion seal, and I also install a new driveshaft. I will have a follow up "Part 2" where I will replace the front seal (transfer case output seal) and I will also be installing the correct driveshaft, since the one in this video is the incorrect size.

Great sound on this!

[@benwrenchin]

Thanks, still needs some work but it is way better

[@victormccoy1974]

Curious……why did you change the drive shaft? Why didn’t you just change your u-joint?

[@benwrenchin]

Basically, the tang where the snap ring holds the u joint in place was bent so bad that I couldn't get a new snap ring to sit in the groove properly.

[@benwrenchin]

31:32 I explain again here why I had to get a new one. Mine was toast after I tried to get the old u joint out.

Thanks for putting the effort on this vedio. My 98 blazer will need a pinion seal changed as it'sleaking.Can this job be done without a impact wrench? Thanks.

[@benwrenchin]

It can. I would suggest the same socket (32mm I think) and a long breaker bar. The longer the better. If you don't have a breaker bar, you can slide a pipe over your ratchet, I use the handle from my jack for that sometimes. That's all you should need it for is the nut that holds the yoke on. Good luck!

[@sar9907]

Thanks man. I will be using a breaker bar or a pipe to loosen the bolt. Thanks for the info. 🙏

[@benwrenchin]

@@sar9907 No problem, let me know if you need more info. You can do it!

[@sar9907]

@@benwrenchin first of all i need to pull the old seal out. head to part store to make sure it matches. There's too many different types and have no idea which one will fit.

@@sar9907 try rockauto.com they have a really good list of parts for so many vehicles, then you can know the correct part number and order it before you start the job
