7.6.2 Tightening the lug nuts
Using a torque wrench, the nuts must be gradually tightened one after another in the order shown in
Figure 34.
Figure 34 — Order for Tightening the Nuts
To tighten them with a hand tool (such as a
pneumatic torque wrench), you will need to adjust
the tool to apply the correct tightening torque.
If you do not, the wheel studs and lug nuts may
become overloaded, which could result in them
being damaged or broken.
An impact wrench can be used to loosen the nuts,
but not to tighten them, since the tightening torque
cannot be controlled with this type of wrench.
Check and tighten the lug nuts:
l
After the first use;
l
After the first loaded run;
l
After the first 1,000 km;
l
Every 6 months or 25,000 km;
l
Each time a wheel is changed or removed.
See Table 19 for the tightening torque to apply to each nut.
7.6.3 Checking that the hubcaps are secure
Regularly check that the hubcaps are firmly in place and are in perfect condition. Immediately
replace missing or damaged hubcaps to prevent dirt from getting inside a hub, which could damage
the bearings.
