E53 4.8is Front Diff Preload Setting

Hiya's,


No good telling you all of my tales of woe ..........



I fubared and hit my passenger side diff case (USA etc Drivers side) where drive shaft goes in the seal, i have lost so much hearing i didn't hear shaft pop out and clouted her again, of cause i put a small crack in the cast case as the pry bar had nowhere else to go except inwards into case lol


I have all the tooling to add a new diff i got, i have a rebuild kit and all seals etc for the swap


Thing is, i've been searching over a week without success for the crush sleeve preload


I've found the spec for the rear diff but not the front


At worst i thought checking preload on replacement diff before i strip but actual preload figure/s be great



Going doolally searching the net lol


Any help/specs be greatly appreciated


Cheers


Tony

Preload spec is for new pinion brgs. so trying to measure before taking it apart would probably give you a really low reading. I don't think you could go wrong using the spec for the rear diff though assuming you are using new bearings?

Hiya,


Yeah the kit is all new bearings/races outer seals (got o-rings and diff to block seal and odds n sods from bmw)


Will set to work stripping the new-to-me diff tomorrow


I will go with the rear spec for my new bearing type unless i get any info beforehand



Just waiting on engine brace to get delivered, typically i dumped a barely used engine crane due to lack of storage space lol


Thanks for the reply :-)


Have Fun


Tony
