Re: Sure Grip Test Proceedure ???

[Roger Pettigrew <dodger7998@xxxxxxx>]

more than likely they will, it would have to be worn pretty bad for it not  
to turn the same way,,,,,,, but it is possible

These posts sound right to me. However, the Sure Gripunit has  clutgh 
dicg's 
in it to allow non lockup when turning a corner. I do not  know (but would 
like to)  how things act when the clutches are badly  worn. , As  there are 
still spider gears, will both wheels turn the  sane direction when they are 
off the  ground?..........................MO
