Guys im going to drain and refill both of my Diffs, Question is Im going to use Royal Purple and for the rear I know to use 75W140 and the front 75W90 right? Royal Purple Gear Lube already has Limited Slip Additive in it, would this hurt the front Diff? My rear has 4:10 LS the front is stock.
Also shoud I pull the front cover off or just drain it?
The rear I have a Mag-Hytec was going to get one for the front but I was reading about clearance issues so im going to reuse the stock cover.
Thanks ~Gage~

 

Does the front cover have a drain plug?

not to my knowledge, i would just pull the cover. that way you get all the old stuff out and can look at the gears for wear/damage.

 

Thanks 05 Super, I will pull the cover.
