Endplay Procedure

Verify Wheel Endplay (Standard Axles)

Verify that endplay meets specification using a dial indicator.
An indicator with 0.001" (0.03 mm) resolution is required.
Wheel endplay is the free movement of the tire and wheel
assembly along the spindle axis.

Correct endplay is 0.001"–0.005" (0.025–0.127 mm).

Note: Endplay when using a Pro-Torq Nut is 0.001"-0.003"

(0.025-0.076 mm).

1.

Attach a dial indicator with its magnetic base to the
hub or brake drum as shown below:

2.

Adjust the dial indicator so that its plunger or pointer
is against the end of the spindle with its line of action
approximately parallel to the axis of the spindle.

3.

Grasp the wheel assembly at the 3 o’clock and

9 o’clock positions. Push the wheel assembly in and
out while oscillating it to seat the bearings. Read
bearing endplay as the total indicator movement.

If endplay is not within specification,

readjustment is required.

Readjust Wheel Endplay Procedure

Excessive Endplay: If endplay is greater than 0.005"

(0.127 mm), remove the outer nut and pull the lock washer
away from the inner nut, but not off the spindle. Tighten the
inner nut to the next alignment hole of the dowel-type washer
(if used). Reassemble the washer and retorque the outer nut.
Verify endplay with a dial indicator.

Insufficient Endplay: If endplay is not present, remove the
outer nut and pull the lock washer away from the inner nut,
but not off the spindle. Loosen the inner nut to the next
adjustment hole of the dowel-type washer (if used). Reassem-
ble the washer and retorque the outer nut. Verify endplay with
a dial indicator.

Fine Tuning the Endplay: If, after performing the

readjustment procedures, endplay is still not within the
0.001"–0.005" (0.025–0.127 mm) range, disassemble and
inspect the components. If parts are found to be defective,
replace the defective parts, reassemble and repeat wheel
bearing adjustment procedure. Verify endplay with a dial indi-
cator.
