I've been good this year so Santa dropped by with the rest of the goodies for this conversion.
Meyle 3147100005 Bearings (Item B)
Meyle with tapered washer
Meyle with ECS rear trailing arm (fits nicely!)
Edit - These Meyle bearings are from the 'Meyle-Original' product line and there's a 'Made In Turkey' sticker on the box (so, not a China product that some people are concerned about).
Comparing the Meyle bearing with a Lemforder bearing I have (for the rear camber arm, hub-side). The Lemforder has a polished outer shell whereas the Meyle one doesn't. However, the Lemforder shell shows rust spots. The Meyle inner ring looks higher quality than the Lemforder one. I tried to spin both bearings and both are tight. Maybe not meant to be spinnable by hand. Hopefully the Meyle ones will last.
BimmerWorld Rear Camber Arm Bearing Kit (Item A)
The BW rear camber arm bearing kit has 3 components - the bearing itself, an inner sleeve (2 pcs per bearing) and an outer sleeve.
Will post more when I have them installed.
