[Mgs] front hub removal problem

[Chris Moog]

Its been a while since I've done the job, but you need to thread 
something on to the bolt and pull it and the attached cup off (I drilled 
a small plumbing pipe cap and bolted it to the cup and then threaded a 
length of pipe to the cap and pulled the cup off).

Under the cap is the bolt holding the front bearings on.  I can't 
remember what prevents the bolt from spinning but it is obvious (cotter 
pin or washer with a flat or pinned washer).  Only other trick is 
setting the free play.

Install the new bearings or clean up the old ones.  Sort the shims from 
thinnest to thickest.  With no grease on the bearings, install the hub 
with the thickest shim only. While slowly tightening the hub retaining 
bolt keep rotating the hub.  If the hub binds stop tightening and 
install more shims.  Final setting is when removal of the thinnest shim 
causes the hub to bind and reinstalling the thinnest shim allows the hub 
to freely rotate when the hub bolt is torqued down.

After finding the shim set you need, disassemble the hub, pack the 
bearings in grease and reassembly with the shims that caused no binding..
