Hi everyone,

I'm having trouble removing the rear allen wrench bolt for the trailing arm it won't budge. Was wondering if there was some tips or tricks to removing this bolt? 1991 formula mx.

big bar + heat

Heat for sure be very carful they really like to snap off.

Are you using an allen wrench or the allen wrench in a socket. I have an allen wrench set and with a breaker bar mine came out really easy. This was on an 88 mx. If your going to use heat you will need to buy new rubber bushings as they will probably be toast after heating them.
