flint54 Posted August 22, 2011 Share Posted August 22, 2011 Surprise, surprise, the axle swap is not quite as "plug and play" as I had assumed. Was puzzled why the rotors would not fit, until I measured the distance from hub face to knuckle face. On the 1992 D30 that distance is 3.25". On the 2001 D30 that distance is 3.00". Gotta go buy new rotors to replace my perfectly good rotors. Rats! Link to comment Share on other sites More sharing options...
Exxon Valdez Jeep Posted August 23, 2011 Share Posted August 23, 2011 Rotors and unit bearings have to be the same year/style, as each other calipers and knuckles have to be the same year/ style as each other I have a 99 HP housing with 2001 knuckles and calipers, and 91 unit bearings and rotors.

mvusse Posted August 23, 2011 Share Posted August 23, 2011 Older and newer rotors have a difference in the thickness of the mounting surface. That difference is made up by the older/newer unit bearings, not the knuckles. So either get a new pair of rotors, or get another pair of unit bearings. Rotors are cheaper. However, your old rotors should work just fine with your old unit bearings. Link to comment Share on other sites More sharing options...
