change rear end fluid?

[chatcher]

you probably should it wouldnt hurt its not so bad take the rear cover off start at the bottom work you way up and itll drain out easy clean it off and use silicone at least or the gasket can be had pretty cheap at most part stores the fill plug is on the driver side its one of those 3/8 ratchet end type of plugs and check your rear end if its limited slip youll need the additive for it if you have the cash laying around an aftermarket alluminum diff cover with the fill and drain plugs in it will make refill easier its a bit of a bitch getting the fluid in the oe fill plug
