For pop-on hubcaps, visually check that they are all the way on.

For hubcaps with screws, replace the gasket each time the hubcap is removed and tighten the
screws every 6 months.
7.6.4 Checking the condition and play of the wheel bearings
The lifespan of the wheel bearings depends on the operating conditions, load, speed, adjustments
and lubrication.
Check the condition and play of the wheel bearings:
l
After the first 50 hours or 1,000 km;
l
Every 6 months or 25,000 km.
To check the wheel bearings:
1. Lift the wheel slightly off the ground.
2. Slowly turn the wheel in both directions to check for any resistance.
3. Turn the wheel quickly to check for unusual noises such as grating or knocking.
If a bearing is damaged, replace all the bearings and seals (see "Replacing the wheel bearings" on
page 79).
To check the wheel bearing play:
1. Lift the axle until the wheel is no longer resting on the ground.
NOTE: Make sure that the vehicle is completely immobilized.
2. Release the brake.
3. Grasp the top and bottom of the wheel and attempt to rock it to check for play.
If there is any play, take it up (see "Adjusting the wheel bearing play" on page 74).
NOTE: For self-steering axles, make sure that the play is not coming from the
suspension or pivot.
7.6.5 Adjusting the wheel bearing play
Figure 35 and Table 20 show the various components of a wheel bearing.
To adjust the wheel bearing play:
1. Lift the axle until the wheel is no longer resting on the ground. For large wheels, remove the
wheel to make it easier to feel the play and see what you are adjusting.
2. Remove the hubcap.
3. Remove the cotter pin or hair pin clip from the castle nut.
