I believe they're the same, not 100% sure as I've never tried to switch from year to year...but they look the same.

Also, are you sure that your wheels are sitting like that because of your bearings and not your ball joints? Have you had your Jeep aligned...could be just a camber issue. Check the front end properly before you just throw a bearing on it.
 
It's unlikely they are the same. At some point between 90 and 95 they switched to composite rotors, and in the process, the depth of the hub changed. You will need to measure the hub from the point where it mounts to the knuckle to the face of the wheel mounting flange. There also was a change in the knuckle design somewhere along the way. The 95 does not have a removable brake caliper slide.

Usually if there's enough looseness to cause a noticeable difference in wheel camber, it will be something other than the bearing, unless your wheel has been wobbling really badly for a long time. Check your ball joints too.

If you can get hold of the whole front axle, of course you could swap the whole thing, but it's likely easier just to get the right bearings.

Three different hub/bearing units were used. The hub/bearing units are the same for both sides of the vehicle. The different years for hub/bearing assemblies were: 1984 through 1989; 1990 through mid-1999 (composite rotors); and late-1999 through 2001 (cast rotors).

84-90 hubs have the bearing in the rear of the assembly recessed 1/2".
91-99 hubs have the bearing flush to the rear of the assembly.
