‘97, 2 wdr, Rear DiffFluid Change

[powerplaytwo]

Looking at the diff, it doesn’t have a drain plug, but does have a fill plug on the front, driver’s side. No tag for special fluid requirements, so I guess 75-90w would be in order. I looked up capacity but didn’t see it on the chart provided by the forum. Would appreciate how much to buy.
Thanks

Make sure you can get the fill plug out before you pop the cover to drain it. I've never experienced a stuck fill plug personally but have head horror stories lol


You'll need 3 bottles of gear oil.. it'll take right around 2 and a half.

A good number of gear oils come with the limited slip additive already in them. Until you know for absolute certain you don't have a limited slip, it's better to have it and not need it than need it and not have it. Limited slips will either have the S-shaped spring thing in the middle of the carrier or will have a fairly solid carrier that you might see a stack of clutch plates or gears in. There is no confusing one for the other and the additive won't hurt anything if you don't have an LSD.

Thank you both for your help. I will order some additive just in case. I haven’t checked yet, but this is a base XLT with not much in the way of extras.
