pretty well frozen but was always able to pound them out and reuse the 
arms. You should never force any part on an MG but you definitely need 
a bigger hammer. If the bolt still won't pound out with one arm off use 
a 'dremel' or other grinder to grind off the head of the bolt to remove 
the other arm. The bolt will be in the kit but the arms are expensive. 
Note the front arms are handed because of the offset holes for the 
torsion bar.

And while we're talking, how did you get the arms/pan assy off the inner 
pivot without removing the spring pan bolts. I've always found it 
necessary to remove the spring pan to change the inner bushings.

Problem is doing a good cleaning job with the old races in, and without 
cleaning how to inspect. Races are easy to change. Get a largish brass 
punch and from the inside of the hub there are 2 notches behind the race 
(180 deg apart) that let you hit the race to drive it out. Seat the new 
one by tapping it into place with the same punch. Just go around it with 
firm blows until you feel it seated. Might as well have new ones.

Good Luck
