Pulling the rear axles...

I'm installing rear disc's soon and have to pull out the rear axles. Should I replace the seals and/or bearings while I'm in there?

There's no leaking or noise though. What do you all think?

i didnt... its just preventive maintenance, but now that ive disassembled it i know how to if i ever need to.

i did however get a lube locker gasket and replace all the hard lines which got destroyed bending them around to the new hook ups

I replaced them. Just a little bit more cost than diff fluid, so I figured that if I replaced them I wouldn't have the need to replace them until at least I needed to replace diff fluid, so I rationalized the cost.

I do tend to get the "while I'm at it" pretty bad and I was swapping in an 8.25 from a JY so I didn't know the history of it and it was sitting on jack stands.
