Incorrect adjustment of the wheel hub bearing clearance will cause the failure of insensitive steering. Learning how to check the wheel hub bearing clearance is also very important for the use of automobiles.

1. Tools and equipment:

(1) One car:

(2) Scissor lift:

(3) Magnetic dial indicator torque wrench outer diameter micrometer 0-25mm S-shaped hook:

2. Steps to detect the clearance of wheel hub bearing

(1) Lift the vehicle to a suitable height and lock it reliably.

(2) When inspecting the wheel hub bearings, hold the upper and lower sides of the tire with both hands, pull the tire back and forth with both hands, and repeat it many times.

(3) Rotate the tire to check whether the wheel bearing is running for noise.

(4) Remove the tire nut and tire.

(5) Remove the brake caliper bolts, and hang the brake caliper stably with an S-shaped hook.

(6) Reliably install the magnetic dial indicator so that there is a certain amount of preload at 10mm from the edge of the hundred face.

(7) Rotate the brake disc for one week and observe the dial indicator reading.

3. Summary:

(1) Lift the vehicle to a suitable height and lock it reliably, hold the upper and lower sides of the tire with both hands, pull the tire back and forth with both hands, and visually check the hub bearing clearance.

(2) Rotate the tire to check whether the wheel bearing is running or not, to judge the wheel hub bearing clearance.

(3) The dial indicator is perpendicular to the end face of the brake disc, and there is a certain amount of preload at 10mm from the edge of the end face of the brake disc. Check the runout of the brake disc to check the hub bearing clearance.
