Actually 247, just repacking those bearings and replacing the seals is a pretty simple process. It might be a bit messy, though it is a lot less expensive than new hubs. A 1999 would be drum brakes and it would be a good idea to check the brakes assemblies at the same time. The brake assembly probably needs bleeding by now as moisture is absorbed by the fluid and the fluid does not heat up like your vehicle brakes and disperse as much moisture.BCB
