If you take the time to verify the hub before installation, any other runout issues will be easier to troubleshoot. As a rule of thumb, on a modern vehicle, hub runout should be between. Also, before installing the new hub check it’s runout. Look for corrosion and make sure a bore gauge rotates in the bore without any trouble. When the old hub is removed, use the opportunity to inspect the knuckle for damage. That can cause premature wheel bearing failure. When you have a failed wheel hub, it’s possible that the bore of the knuckle is damaged, too. Failing to Inspect the Bore and Measure Flange Runout Don’t use any lubricants on the axle shaft threads. You can use a wire brush, emery cloth, or a fine file. It’s important to ensure that both areas are clean before installing the new hub. There may be debris in the axle shaft and on the wheel speed sensor that could affect your new hub’s performance. Failing to Clean the Axle Shaft and Wheel Speed Sensor Self-staking nuts are only intended to be tightened once. Sometimes it’s tempting to reuse the old nut. Failing to Use the Provided Self-Staking Nut

The amount of torque you use makes a big difference in your wheel hub’s performance. A torque wrench is specifically designed to help you torque a fastener to a precise measurement, which is necessary when installing a wheel hub assembly. But they do not tighten to a precise amount of torque. of torque, which is more than most automotive engines. Modern impact wrenches are very powerful. Standard or digital, torque wrenches are better than impact wrenches for these jobs.
