Hello all. My recently purchased u42t minicab has noisy pinion bearings. I have read nearly every post here, searched the Internet but have still not found an interchange for the Mitsubishi part number. The local dealer says they are obsolete. I have found some posts with references to other rear ends being similar but no concrete results. I would like to have new bearings in hand before I pull the third member if possible. Reading the dimensions from Mitsubishi it is an extremely small pinion, at least a half inch smaller than any small rwd diff I could think of to compare. Someone out there must have pulled one apart and crossed the numbers on the bearings. Thanks for any help.
