Emergency repairs
13.9 JACKING UP THE REAR AXLE
WARNING! Not using the indicated jacking points of the vehicle and
supporting the vehicle when jacking up can lead to the vehicle falling
off the jack, resulting in getting jammed or damage to the vehicle. This
can lead to dangerous situations and serious injury.
– Always place the vehicle on a firm and level surface.
– Before jacking always secure the vehicle to prevent it from rolling
away by applying the parking brake and/or using wheel chocks.
Never release the parking brake while the vehicle is jacked up.
– Always position the jack on a firm and level surface. If the surface
is not firm place the jack on a support plate.
– Position the jack only under the spring attachment when the rear
axle must be jacked up.
– To prevent deformation of the axle housing, the jack must under no
circumstances be located directly under the axle housing or the
differential casing.
– Always use stands to support the chassis when carrying out
repairs or service under a vehicle which rests on a jack.
– Do not carry out any work underneath a vehicle that is only
supported by a jack or lifting gear.
13.10 CHANGING WHEELS
WARNING! Tension can be present in a cracked or damaged rim that
holds an inflated tyre. The tyre or rim may crack or burst when the
wheel is changed. This can lead to dangerous situations and serious
injury.
– Always deflate the tyre and remove the tyre valve if a wheel with a
cracked or damaged rim is removed.
– Only use the original DAF rims specified for the vehicle concerned.
– Make sure that tyres of the same type and size are fitted on both sides of the axle.
– Always observe the tyre load capacity and speed index required.
– Insufficient cleaning of the mating surfaces and/or uneven tightening of the wheel
nuts may cause vibrations during driving or braking.
NOTE: If a wheel stud is replaced, check the other wheel studs on the
relevant wheel hub, and if necessary, replace the other wheel studs.
Check the wheel nut of the replaced wheel stud. If in doubt, replace the
wheel nut.
Removing wheels
1. Chock the wheels to prevent the vehicle moving off.
2. Clean the screw thread of the wheel studs with a wire brush.
3. Oil the wheel studs sparingly.
4. Loosen the wheel nuts a few turns.
