When should I replace my hub assembly?
Most serviceable wheel bearings need maintenance every 25,000 to 30,000 miles, or during every brake service. But, the average life of a sealed wheel bearing and hub assembly is about 85,000 to 100,000 miles, without the opportunity for a technician to repack the bearings.
What happens if you over torque a wheel bearing?
“Excessive preload will cause excessive friction and the bearing will run hot, compromising lubrication and eventually leading to flaking (material coming off) at the large end of the rollers/races,” he says. “On the other hand, adjusting the bearing too loose causes excessive looseness and vibration in the system.
Should you grease new wheel bearings?
YES, they need to be greased with BEARING GREASE unless you bought the bearing and hub pre-assembled from Timken and spent hundreds of dollars.
What happens if you don’t tighten axle nut?
Yes, the vibration and movement of a loose C.V. axle nut can cause damage to the wheel bearing. Alternately, if that nut is too tight, that also can cause damage to the wheel bearing. There is a specific torque that your car’s manufacturer has specified for that nut.
How long can you drive with a bad wheel bearing?
To avoid this situation, it is recommended to drive at the slower speed so that your wheel stays in action a few more hours. SO, while thinking how long can you drive on a bad bearing? You should not go more than 1000 miles as it might result in some bigger issue.
What to do when your abs light comes on after a wheel bearing is replaced?
If you have an ABS light on after wheel bearing replaced, you may have to also replace the other wheel bearing hub. Car makers sometimes install the toothed tone ring inside the wheel bearing hub and mount the wheel speed sensor on the outside of the hub.
What to do when your wheel bearing is stuck?
If the threads aren’t too screwed up on the axle yet, put the castle nut back on, but backwards so you don’t mushroom the end as much. Then go back and forth between beating on the puller and beating directly on the axle with your sledge. It’ll take time, but has always worked for me.

What causes grease to leak from a wheel seal?
Grease is leaking from the bearings The wheel seal is supposed to fit very tight in the wheel assembly and protects the wheel bearings from dirt, water, and other debris that can cause damage. Inside the wheel bearing is a tremendous amount of grease that keeps the bearings running smooth, cool and free.
Can a bad caliper cause a bad wheel bearing?
This is normally indicative of a bad caliper and/or a bad equalizer, which is not bearing-related. Severe looseness related to a worn or damaged bearing can cause excessive runout, which can cause uneven wear on the brake pads and/or rotor.
What are the symptoms of a worn wheel hub bearing?
• Grinding when the vehicle is in motion. Typically, this means there is mechanical damage in a wheel-end system. Related to a bearing, it means a loss of integrity such as roller or raceway damage. The noise is normally heard when turning or when there is a shift in load. • Knocking or clunking.
