My pinion bearing is going bad and I was looking to get a complete overhaul kit for it. Rock auto carries the kit but under 99 jeep Cherokee they have 2 different kits. One for a short pinion d30 and the other one just says d30. My question is which kit is the one I would need for my 99?

Im guessing its for highpinion, or low pinion.
Get under there and take a look

I have a high pinion d30 but the info for the kit doesn't say anything about high pinion or low pinion. Just short pinion.

All high are short, reverse cut gears.

Okay so then I need the short pinion kit. Thanks for the info.

Well I went and bought the short pinion kit for my hp d30 but I think its the wrong one. The box says for '00 & up XJ which would be a low pinion d30.

Doh.

Yes you indeed got the wrong one if you have a hp 30. The words standard rotation basically mean for low pinion 30s in tj's or late model xj's

Well after this hassle I understand now. I ordered it on the information that was posted above I guess I just misunderstood it.
