99\ 97 hp d30 hub unit
Guys I have a 99 xj which had the front axle replaced with I believe a 97 hpd30 these should be the same yes?
I'm replacing hubs but do not know which part number to get. I think they might be cast but I don'tknow. I'm going with Timken btw.

99 was a transitional period for the unit bearings. Around mid 99 they changed. You will need to order them for the 97 axle.

I stumbled across the differences (3 I know of) in the unit bearings when I tried putting a spare UB off a 98 on my 89.
All I can recommend is pulling a UBs off each axle & compare them. The differences thicknesses, if any, should be fairly obvious.
