 AMSOIL Synthetic Multi-Purpose Grease Provides Superior Protection for Automotive Wheel Bearings

Because wheel bearing failure can cause loss of steering control and separation of the wheels from the vehicle, indications of wheel bearing problems cannot be ignored. The first symptom of trouble is usually a rumbling, growling, chirping or cyclic noise from the wheels. This noise is often proportional to driving speed, but unlike differential, transmission and U-joint noises, it does not change when accelerating, coasting or decelerating. Although the noise may change while turning, it should not be confused with the noise created by a worn or damaged outer CV joint on a front wheel drive car, which usually makes noise only when the vehicle is turning, not when driving straight.

A recent trend in the automotive industry is the return of serviceable wheel bearings. The 2WD Ford F-Series and GM Colorado and Canyon models, for example, feature wheel bearings that are not factory sealed. While a problematic sealed bearing assembly must be replaced, serviceable bearings may be removed, disassembled, cleaned and inspected. If the rollers, balls and races show no signs of wear, pitting, cracking or damage, they may be reused.

Factory-sealed wheel bearings and hub assemblies do not require re-greasing and have a typical life expectancy of between 85,000 and 100,000 miles, while serviceable bearings typically call for cleaning, inspection and repacking with fresh, clean wheel bearing grease at 30,000 mile intervals. Use a quality high temperature wheel bearing grease, such as a #2 NLGI lithium based grease, or a synthetic wheel bearing grease.

In order to remove contaminants, the old grease should be removed and the bearings cleaned and inspected prior to repacking them with fresh grease. Because used seals can leak and contaminate brake linings or lead to premature bearing failure, new grease seals should be used when installing wheel bearings.

When a vehicle experiences a wheel bearing failure, it is a good idea to pay close attention to the other hubs on the vehicle, especially if the vehicle has a lot of miles. If one bearing has failed, chances are the other bearings require service as well.
