Recommendations
Use a very good quality ball joint puller to remove the track rod end and the ball joint because the force required is very important. If you break your ball joint puller, do not hesitate to invest in a better quality tool.
A bearing seal removed with a screwdriver is usually damaged. Provide a new seal before each disassembly.
Bearings are pre-adjusted assemblies. In the packaging, the rings and rollers of each bearing are either connected by a plastic link or in a plastic bag. Never mix the elements of one bearing with the elements of another. This could impair their operation.
