So I'm replacing my spyder gears, I hear somewhere while I have the diff open I should replace other things, anyone got a list of stuff for me to replace?

EDIT: This is the back diff I have open.

 

How many miles? Why are you replacing the spider gears? I just changed gears in my truck and replaced the carrier bearings, pinion bearing and axle bearings. Also axle seals and pinion seal. 2.9 quarts of 75w-140 syn. gear oil. That would be a complete rebuild minus gears.

 

I am replacing them because I have shards of metal coming off of them. I am about to hit 170k miles.

 

I would replace all bearing. Including the pinion bearing which you will have to pull your pinion gear.

 

Ok, thank you.

 

Are you doing the work yourself?

 

No, I'm having our mechanic do it. I figure if there is other stuff I should replace, I need to do it right.

 

just have your mechanic do a total rebuild, since t has fairly high mileage. You could also have him inspect ring and pinion for damage, Or excessive wear and tear, and if it's bad replace them also
