Applications

Tech Note 1: Product Note
Unlike conventional grease, Closed Knuckle Lubricant is thin enough to ooze into the axle u-joints and knuckle bearings/bushings. Differing from conventional SAE 140 and SAE 250 gear lubes, the high viscosity, semi-fluid nature of our Closed Knuckle Lubricant insures it will NOT significantly leak past Knuckle Ball Seals that are in good condition. This combination of properties makes Closed Knuckle Lubricant the ideal product for closed knuckle u-joint and king pin bearing/bushing lubrication.

Tech Note 2: Leaking Differential Oil
Due to the age of Dana Closed Knuckle axles, one often finds the inner axle oil seals are leaking differential oil down the axle tubes and into the Knuckle Ball. Besides the obvious risk of burning up your gear set from lack of lubrication, the leaked out gear lube will dilute your Closed Knuckle Lubricant and in advanced cases wash out the front wheel bearing grease.
