I have a 1988 Justy.It ran fine until one day it just seemed to let loose....like it went out of gear. I was able to push it out of the way, where is has been sitting. Now it will not move at all..even in neutral, and makes a grinding noise on the front drivers side when it is put into gear. This of course is making it impossible to get it towed anywhere cheaply. What could be the cause of this??It is an excellent runner, and I would love to have this fixed! Thanks in advance, Lindsey
