Front unit bearing Swap Q's

Hey guys,

My front wheel bearing is shot and i have to change it out.

money is tight but i have two old unit bearings from when i put the HP D30 in.

My question is, will the old unit bearings work with my calipers etc, that has to bolt on to it?

the old unit bearing are from a 93 XJ, my jeep is a 00 TJ.



I just painted it too...Should have figured out the vibes before wasting money on paint







any help would be appreciated as my wheel is about to fall off

Not sure which combo you ended up using in your swap. But, the unit hub on the TJ changed somewhere around 2000, so my guess is you can't use it. It is about 1/4" difference so you should be able to tell by taking a close look.

97 TJ Sport OPJ project (other peoples junk) I can't remember the last time I bought a new part.

Front unit bearings are dimensionally matched to the brake rotor hat dimension (depth). Most older rotors are deeper inside the hat. Did you swap your late model TJ brake rotors to the XJ hp30 axle?

Put your bad/to be replaced unit bearing on a table next to your old XJ bearing. You'll see the difference in the flange depth.


older, deep rotor hat bearing on the left....newer shallow hat rotor bearing on the right.

thanks for the heads up camper....that's exactly what i was looking for.

i used the existing brake rotors from the TJ.

i used the axle tube and gears(obviously) from the XJ and kept the knuckles shafts and bearings from the TJ.

good info, thanks again!
