Racejeep is getting some new parts, and its my first 99. I went to buy brakes and found out about the 98/00 split. Its 2wd, which I dont think matters, but Im pretty sure they are the same hubs/brakes on my 97.

Now that being said is there any gain over one or the other? Im planning on replacing my hubs and brakes so I can run either style. Is there any difference as far as track width, or reliability, anything? Im a big believer in the fact that companies dont change designs for no reason.

Let me know what you think, Im looking to get them done ASAP.

No ideas

Pull your stuff off and get parts that match up with them at the store. I don't think the 2wd bearings or rotors changed, but I could be wrong. The knuckles are the same on everything.

I would just make sure to get quality bearings. Timken is regarded as the top of the line.

The unit bearings (uni bearing/hub) is the same wether 2wd or 4wd. The difference is the 2wd versions have a "dummy stub shaft" holding them together. The only other difference was the addition of the reluctor ring (ABS sensor) other than those two cosmetic differences and caliper changes, the whole D30 setup has remained unchanged.

'98 featured composite rotors which is a stamped steel hub riveted/welded/somethinged to a cast braking surface. '00 brought back a full cast design which is a single cast unit. 1999 was the transition year and could have either one, the only differenve as far as hubs are concerned is the length of the lug studs! The visual difference is pretty obvious on OE, however replacement rotors are probably full-cast made to composite spec or difficult to tell apart. You'll need to measure the thickness of the rotor's mounting surface, or just get the length of the studs as most hubs are sold with those specs anyway.

I recommend Timken and SKF.

I replacing the hubs and rotors, so what I have now is not an issue. An Im aware of the change, Im just wondering If one is any better than the other. So far it seems like the 00 is less expensive.

Ohh. Full cast is generally considered superior.

Well after market rotors, like said, will all be cast. Just wondering if there was a gain otherwise...but like I said one is cheaper...
