tech note

If you need a Bearing Cup Installer Plate for your axle, order QT1819 Bearing Cup Installer separately.

tech note

You must pack your knuckle bearings with a suitable lubricant such as QU90018 Pyroplex® Protection ES Synthetic Grease before installation to provide initial lubrication.

tech note

In service, the knuckle bearings are designed to be bathed in a semi-liquid Closed Knuckle Lubricant inside the enclosed steering knuckle. If your 4x4 has lockout hubs, you should drive the vehicle with the hubs engaged at least once monthly so the axle shaft will fling lube to the upper knuckle bearing.

tech note

If the vehicle manufacturer recommended steering knuckle lubricant is not available, Dana recommends SAE 140 grade gear lubricant for the knuckles. However, straight gear lube will almost always seep past the knuckle seal which covers the inside of the tires, stains the garage floor and is unacceptable for current environmental standards. What I do, is mix SAE 250 weight gear lube with grease to make a semi-liquid lubricant which will flow into the bearings and u-joints, but not seep significantly past the seals.

tech note

Shims are used between the King Pin Caps and Steering Knuckles to set your Knuckle Bearing/Bushing turning preload. More shims decreases preload, less shims increases preload. King Pin Caps are shimmed to put the specified turning preload on the bearings. The amount of turning preload on varies by vehicle and year but the value is measured by a beam or dial type torque wrench (refer to the vehicle manufacturer Service Manual for your specific model specification or if a manual is unavailable, see Tech Note 7). Too loose can cause poor steering or "Death Wobble", too tight will lead to rapid bearing failure, broken parts, and possible steering loss.

tech note

The Knuckle Bearings MUST be shimmed to provide correct knuckle turning preload. The critical measurement is the amount of force required to move the steering knuckle through the turning arc. The measurement is taken by attaching a beam or dial type torque wrench to one of the King Pin Cap screws. Do NOT install the knuckle seal, axle shaft, or tie rod before setting turning preload. Dana recommends the following turning preload for Dana 25, Dana 27, Dana 30, and standard Dana 44 steering knuckles:
5-10 lbs. ft. for axles with tapered roller bearings top and bottom
10-20 lbs. ft. for axles with upper bronze bushings
