- First step was to remove the dampers. Remove push rod from lower wishbone. Undo damper bolts starting with the lower bolt.
- The misalignment spacers on one of the dampers was tough to remove, but eventually they got out with some help from a blow torch. Warning! Heating bearings could give off hazardous fumes. These fumes can be harmful to the eyes and to the lungs, if inhaled. Source: SKF.
- Remove retainer circlip with a pointy sharp tool.
- Carefully remove bearing using a socket and a hammer.
- Bilstein part number E4-B46-610. Can be obtained from Caterham Parts or directly from Bilstein. You can also find similar bearings at your local bearing shop in different qualities.
- When I fitted my new bearings I noticed a small play between the new bearing and housing. I used Loctite 648 retaining compound as glue. I don't want any movement there, or the shocks could easily be ruined. I hope the new bearings will outlive the shocks, as they probably is going to be tough to remove in the future. (Heating them might work)
- Reassemble. A good opportunity to replace the bolts and nuts as well.
Note: I have the "race spec suspension" on my car. The procedure and part numbers may be different on the road spec dampers.
I changed the upper bearings on both sides as I thought that would be enough. Now when the suspension is reassembled I can still feel a small play in one of the lower bearings, sigh...
