I have an 2004 Freightliner Sprinter that the rear end bearings started to whine and decided to rebuild it myself due to financial reasons. My question is when I pulled the diff apart there didn't seem to be a spacer between the rear pinion bearing and the crush sleeve (collapsible spacer). Is this normal? I want to assemble but this boggles me. mfg date is 03\04 so its the later diff I guess since they changed in 02/04. Is this right? Any help from somebody who knows would be appreciated. note: The crush sleeve that came in the kit is identical except about 1\8" longer but it hasn't been crushed yet. All bearings are the same so it appears I got the right kit but no pinion spacer is available. Thanks
