True, as they are Richmond Gears I would agree, butif the pinionnut was over tightened and crush sleeve was over torqued it will damage the pinion bearings. When you set preload on the pinion bearings you are measuring in inch pounds NOT FOOT POUNDS. Used Bearings set around .006 to.008 inch pounds and New Bearings set around .012 to .015 inch pounds.

Just put 4.10s in mine today and they whine!! Guess I'm on the gear whine wagon to!! But they feel good! Hopefully I get some good ETs at the track tomorrow.
