Rearend Fluid & Stuff Question

[99CANADAHAWK]

:umm:Just have some a quick questions : My rear pinion seal is leaking a little and was thinking of fixing this spring I bought some Royal Purple rear gear fluid and was wondering if I will need to add some of the GM additive to this aswell ?

Also I was going to change to rearend girdle at the same time to either the SLP/AAM cover or the T/A Performance cover , is there any difference between the too ?

Thanks .

I believe the Royal Purple already has the additive in it, no need to add the GM additive.

I was always told not to use syn's on clutch type diff's.

I have the Torsen diff not the Auburn is it a clutch type diff ?:dunno:
Also any idea`s on wich diff cover to buy ?

I have had the TA cover for about 2+ years and really like it.

How hard is it to change the pinion seal?
