Using these wheel bearings is easy. First, make sure you have all the necessary tools on hand. Then, remove the old wheel bearings carefully. Install the new bearing with the included 8 wheel studs and ABS brake sensor. Follow the torque specs we provided: 133 lb.ft for the spindle bolts, 188 lb.ft for the axle nut, and 221 lb.ft for the caliper bracket bolts. When it comes to the optional spindle O - ring, lightly grease it before installing it to protect the wheel bearing and axle from corrosion. It's a good idea to replace the O - ring every time you change the wheel bearing. For maintenance, check the bearings regularly for any signs of wear or damage. If you notice anything unusual, like strange noises or vibrations while driving, have the bearings inspected right away. Remember, your Kryptonite wheel bearings come with a lifetime warranty, but you need to buy them from an authorized dealer and register the warranty within 90 days of purchase.
