i dont think i spun out a wheel hex... but how would i go about seeing if these two were the problem... ive looked everywhere everything seems normal[:@]

Take off the wheel, and see if it is stripped out where the wheel hex goes in. For the pin, just take off the wheel hex; the pin goes through the axle and sits in a groove in the wheel hex.

does it stick out at all or is it flush with the axle?.... because I .... already checked that and it looked good to me.... it seems to me the problem is somewhere else.... if i spin the back wheels the dog bone spins... if I spinthe front wheels the dog bone dosent...[:@]

The pin fits in the hole in the axle and the hex slides over the top of it. The pin is what makes the hex spin. Here:

I compaired both rear wheeels/ parts... they are exactly the same... no parts missing.[]

Well thanks for the help... I guess its time for a visit to the LHS... [&o]
