Great information so I wanted to ask you a question. I have a 2016 freightliner cascadia and freightliner dealer shop replaced my the bearings on the power drive axle and about 2 days later I noticed my hub was leasing oil so i tightened the bolts as all of them were not tight so I thought maybe de dealer failed to tight them to specs, so I replaced the gasket as it was ripped in pieces and tight them enough but it happened again, the bolts were loose and the gasket was again torn to pieces. What could cause the nuts to come loose again. I will appreciate it if you can try to give me your theory on whats happening. Note when I tightened bolts on the hub to about 120 lbs then my other wheel on the same axle started leasing too. I contacted the dealer but I am too far to drive there. Thanks
