Yesterday I did the passenger side and let the bearings soak overnite, today I reinstalled the passenger side. When I dissassembled the passenger side a couple of things I noticed 1) the lock nut was only on finger tight. but there was no play in the bearings, so I guess the adjusting nut held ok. 2) the snap ring on the shaft held in a "washer", it had the convex side facing outward whick makes sense. Now today I find the washer on the driver side with the concave side facing out. Which is the correct way for the washer to be installed ??? Also what is the purpose of this snap ring and washer???
