Sodium based grease is not compatible with lithium based grease. Read the package labels and be careful not to mix the two types. If there is any doubt as to the type of grease used, completely clean the old grease from the bearing and hub before replacing.
Before handling the bearings, there are a few things that you should remember to do and not to do.DO the following:
Do NOT do the following:
The front wheel bearings only on rear drive Volvo models require periodic maintenance. A premium high melting point grease or equivalent must be used. Long fiber type greases must not be used. This service is recommended every 30,000 miles (48,000 km).
For information on Wheel Bearing removal and installation, refer to Suspension & Steering of this guide.
- Remove the wheel bearing.
- Clean all parts in a non-flammable solvent and let them air dry.
Only use lint-free rags to dry the bearings. Never spin-dry a bearing with compressed air, as this will damage the rollers.
- Check for excessive wear and damage. Replace the bearing as necessary.
Packing wheel bearings with grease is best accomplished by using a wheel bearing packer (available at most automotive parts stores).
If a wheel bearing packer is not available, the bearings may be packed by hand.
- Place a healthy glob of grease in the palm of one hand.
- Force the edge of the bearing into the grease so that the grease fills the space between the rollers and the bearing cage.
- Keep rotating the bearing while continuing to push the grease through.
- Continue until the grease is forced out the other side of the bearing.
- Place the packed bearing on a clean surface and cover it until it is time for installation.
- Install the wheel bearing.
