Re: [Chrysler300] axel end play on 300C

I see the only logic you over looked is expansion of metals. Dave S. said 
it . You have to allow for expansion of metals or you may get pre load on 
the outer axle bearings. This will lead to premature bearing failure.
Warren below makes another point that his International manual calls for 
.001 to .009. All I can say, different vehicle, design and engineers. 
Warrens second point why has there not been posts when someone set up at 
.006 and not .018. My guess is if one started to notice a growling axle 
bearing and disassembled to see a trashed bearing the first thing you would 
think the bearing went bad. I am not saying Chrysler engineers had it all 
figured out, but for now I think I will stay with manual spec's.
I was going to mention it then Owen post it. The rear axles we are talking 
about the outer axle bearing is not lubricated by gear oil. They are 
isolated from gear oil by the inner axle seal. These bearings must be 
packed like front axle bearings and need maintenance .like front wheel 
bearings. Theres a winter job for you.
