Noise Acceptability

A gear-driven unit (especially on a drive axle) will produce a certain amount of noise. Some noise is acceptable and may be audible at certain speeds or under various driving conditions, as on a newly paved blacktop road. The slight noise is in no way detrimental to operation of the rear axle (4001) and must be considered normal.

Vehicles equipped with a limited slip Traction-Lok® differential may exhibit a slight stick-slip noise (chatter) on tight turns after extended highway driving. This is considered acceptable and has no detrimental effect.
