Removal
Remove the wheel hub.
Using a screwdriver, remove the radial seals -A, E- from the hub "C". Remove both tapered roller bearings -B, D-.
Knock out the bearing races using a copper rod. In doing so, place the rod circumferentially against opposite sides of the race to prevent it from becoming skewed.
Note: To avoid burrs forming on the clip, use only a perfect rod.
Installation
Clean the areas under the bearing races and radial seals in the hub.
If burrs have formed on the seating areas when knocking out the clips, they should be removed.
Carefully push the outer and inner bearing races to the stop using a suitable short pipe. The outer diameter of the pipe must match the diameter of the race.
Fill the tapered roller bearing with bearing grease (for example, Liqui Moly LM-320). In this case, all cavities between the rollers must be filled with grease.
Caution: Do not fill the space between the bearings with grease. Excess grease in the hub will be squeezed out through the radial seal.
Insert the outer bearing "B" and drive in the new radial seal with a suitable pipe. Pre-fill the space between the sealing lips with grease. This reduces the wear of the sealing lips.
Install the inner bearing "D" with radial seal "E" in a similar manner.
Install the wheel hub.
