12-Bolt Spool Bearing Pre-Load

Thomas,

my method that has proven to give excellent results;

I select a shim pack that provides the backlash number I want and those shims will GENTLY tap into place with a small hammer. Thus, very light preload. It does require several trial fits to sneak up on the combination.

And speaking of preload, I also use very light preload with the pinion bearings and install a solid spacer that adjust with a shim pack.

When the install is complete as I describe the complete assembly is very easy to turn and the car is very easy to push.
