xj's do use crush sleeves in the d30's but you don't need to reshim the carrier as long as you reuse or use the same amount of shim when replacing the pinion bearings. and while you are at it you might just as well replace the carrier bearings. a shop will charge between 6 and 8 hours to do the job,but most competent wrenchers cand do it in their garage.
