I recently bought a set of 31-spline axles for my 70 mustang and found that the bearing thickness between the stock bearing and the new Moser bearings are .41 difference. This is a small bearing housing which originally had 28-spline axles. The 9" axle housing has the bearing cutout so that the bearing is recessed in the housing and the retainer plate bolts over the bearing to the housing flange. I can see the old stock retainer plate is bent a little due to the stock bearing being about .10 wider than the housing allowance. I am not sure if I am explaining this so that it can be understood but I am doing my best. I was curious if anyone else has had this problem. Moser says that the retainer will bend over the bearing to attach to the housing flange with no problem. The retainer plate is atleast 1/4" thick or more. Anyone had this problem? Please help.
