Verify Wheel End-play Procedure
Verify that end-play meets specification using a dial indicator.
An indicator with .001" (.03 mm) resolution is required.
Wheel end-play is the free movement of the tire and wheel
assembly along the spindle axis.
Correct end-play is .001" – .005" (.025 – .125 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 end-play as the total indicator movement.
If end-play is not within specification, readjustment is
required.

Readjust Wheel End-play Procedure
Excessive End-play — If end-play is greater than .005" (.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 re-torque the outer nut.
Verify end-play with a dial indicator.
Insufficient End-play — If end-play 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 re-torque the outer nut. Verify end-play
with a dial indicator.
Fine Tuning the End-play — If, after performing the readjust-
ment procedures, end-play is still not within the .001" – .005"
(.025–.127 mm) range, disassemble and inspect the compo-
nents. If parts are found to be defective, replace the defective
parts, reassemble and repeat wheel bearing adjustment pro-
cedure. Verify end-play with a dial indicator.
