All Balls needle bearings, what spacer do I use?

[big-b]

You have't driven the lower outer race far enough into the frame. Looks to be about 3 - 5mm short of where it should be. Use a soft, aluminium, copper or brass drift and work your way round the bearing, keep going until it won't go in any further. You'll know when it's right as the noise will change.

Thanks, all set now.
