well interested in 30 splining locking and gearing my d30 also may buy a. Rear d44. And I'd lock and gear that maybe chromolys where would be a good site to buy packages

cal said:Best off order yourself a TNT truss, and call up reider racing to get a 30 spline arb, 30 spline unit bearings, 30 spline inners and outers, and then some form of superjoint for the axles - I am a big CTM fan. ...... really stiff diff cover (crane, riddler, etc).

What about an OX? They make a 30 spline d30 unit and it comes with the diff cover. I know it's newer and doesn't have quite the reputation of ARB, but it seems like they're gotten past some of their initial problems and a cable appeals to me more than air hoses.
Is a 30 spline always the same diameter? Does a Dana 30 30 spline have the same axle diameter as a Dana 44 30 spline? Maybe it's obvious, but I've haven't been able to find any info on this.
I didn't see you mention hubs, would new 30 spline outers require that?

Are '00 and '01 unit bearings different than earlier?? excuse my ignance...:viking:cal said:Alloy-USA has a 30 spline unit bearing setup. It uses the 2000+ unit bearings, so you may have to buy new rotors (2000+) to go with it. Small cost all things considered. It keeps the 5x4.5 bolt pattern.

Interesting...so, can I use calipers from an '01 on a '96 HP D30?? And I'm guessing the rotors will not be interchangable......cal said:There are 3-4 different unit bearings for XJ's, with different offsets. It just affects how the rotor is centered in the caliper - as long as the rotor matches the bearing you're good.
The 00/01 XJ has the same bearing 2000+ TJ's have, as part of the low pinion 30 package. I imagine that is why they went with that unit bearing for the 30 spline kit - more people are likely to be beefing up new tj's than old xj's.

Thank you for the quick info! You ARE a wealth of D30 knowledge:wave1:
Thanks! I've got a 96 HP D30 regeared (open) sitting in the back yard waiting on the 8.25 to get locked and regeared, and I was wondering how difficult that front end swap will be. There is usually atleast one surprise in most of my projects:rattle:cal said:there are two types of knuckes (early and late) with two typed of calipers. 96 and 01 should be the same iirc. 96 and say .. 87, wouldnt be the same.
