We'd need more detail on the "wheel hop."
Does it only occur in first gear? Does it only occur below a certain speed? Does it only occur when traveling straight-ahead / cornering / both?
Which wheels are affected - only one axle or both axles?
Does it occur only during acceleration or under constant speed as well? Does it occur continuously while these conditions exist or only for a moment - even if the conditions remain unchanged (i.e. same gear, same load, same speed, same steering input)?
