I have done some research and looked at some posts but have had a little trouble finding a good answer. The speedometer works ok, except for the bouncing, it will get up to highway speed for a while then drop out to 10-15mph, while i'm still doing highway speed. Anyway took everything apart and took off the right angle drive. the square shaft coming out of the drive feels loose and wobbly. Is this normal, or should there be no play?
