[SEL] Re: Pinned Rings - Problems or Not?

[Steve Royster]

Yes Dave, You hit it right on. The axles were reversed with the right on 
left and the left on right and everytime I pulled it down the driveway the 
nuts unscrewed themselves and the wheels  fell off. I can't figger out how 
to fix this problem so  I push it now insterad of pulling it to shows! But 
on Mondays and Fridays it doesn't seem to matter very much.  The Oystered 
Cloister
