subaru tech tip 1During removal and installation it’s important to follow manufacturer guidelines, but it’s also important to review some additional tips to help determine the root cause of bearing failures.

Prior to removal, perform a flange runout check. This will identify a bent or damaged flange. A new wheel flange will also help prevent damage to the old wheel flange if the inner ring of the bearing remained on the old wheel flange and has to be removed.

After removal of the old bearing, it is important to measure the bearing housing (knuckle) for roundness. Use a bore gauge to help determine if an issue exists. If the bearing housing is out-of-round, it will be necessary to replace the knuckle.

There is an option on the market for a ball bearing design that may not provide enough load-carrying capacity or strength. Consider installing a wheel flange kit which provides a tapered bearing for increased longevity.

During installation, add some additional premium wheel bearing grease. This is an important step to perform in order to reduce heat and friction that can wear a bearing out quickly.

Make sure to replace all three of the wheel seals. It’s vital not to reuse the old seals that may allow for bearing contamination, including water intrusion.

Install a new C-clip to help provide proper retention of the new bearing in the knuckle.

Follow manufacturer’s specification for axle nut torque. The new axle nut will help provide correct clamp force retention when properly torqued.

Adjusting Parking Brakes

You should never estimate when it comes to parking brake adjustments.

The parking or emergency brake has to perform two distinct jobs. First, it must be able to hold the vehicle on an incline. Second, it must be able to stop a vehicle under a specific distance if the hydraulic brakes have failed. These standards are set by the Department of Transportation (DOT), and the kicker is these standards must be met with the force applied by a little old lady. But, over time, the cables can stretch and the friction materials change their length and thickness, which is why adjustments to the system are required.
