How hard is it to change a pinion seal? It's a 98 ss convertible

 

Remove driveline,
Remove large nut holding the yoke to the front of the diff.
Remove yoke
Remove seal (being careful not to hurt the pinion)
Clean yoke
Clean diff around pinion seal area.
Carefully press in new seal
Put some light oil on inside of seal to prevent tearing when the yoke is reinserted.
reinstall yoke.
Reinstall nut and torque to spec.
Reinstall driveline.
Have a beer after you test drive car.

BEFORE you remove the pinion nut, count the number of teeth that are showing on the pinion shaft, and make a reference mark lining it up to the nut. When reinstalling the nut, make sure the same number of teeth are showing and your reference marks line up. DO NOT under any circumstances torque the nut to any "specs", or you will alter your gear mesh and shorten the life of the ring & pinion gears. Doesn't matter what any book may say, you want the nut in the same spot it's at right now, and torquing it in any way will change that spot.

 

^^ Sorry about that I forgot this is not the kind of pinion yoke that you torque to spec. I am too used to my old trucks when it comes to the diff.

Ok cool im gonna attempt it. What about front input shaft seal??

 

Same as above....only different. Slide slip yoke out, remove old seal, install new seal, lube shiny part of slip yoke with tranny fluid, slide back in. I also like to dress down the surface of the yoke with 1000-1500 wet or dry to take the glaze off, and to help it "break in" with the new seal.

 

I was waiting for you to reply thus why I did not

And, you weren't pointing at me when you were talking about the nut; were you?
