used to be caused when rear axles supported by cart springs. As you set off the springs wind up, then when you loose traction the torque in the spring is released and the axle tramps. similar as you say when you get on the edge of loss of traction it feels like the back end is jumping up and down.

...hence older muscle cars were fitted with "tramp bars" on the axles, they torque over and hit the ground when you stamp on the gas to prevent the amount of wind up in the suspension and stop it from bouncing.
Ive had a similar experience in a couple of exotic performance cars (both beemers actually) where I wasnt brutal enough with the loud pedal for a staright-out spin and got a fair old bounce out of the back wheels. I automatically referred to it as axle tramp but was quickly re-buffed by the owners who claimed it was the mark of a well sorted rear end that resists wheel spin of any sort and the bounce was a side effect. hmmm...

Hi,
Sounds like another name for Wheel Hop then ?? My Hyundai really suffered from it until I sorted the engine mounting etc out.
Some of the GTO drivers complain about it - I have not attacked the Monaro enough to find out what mine is list. Looks like its polly mount to fix on our cars (also an uprated sway bar helps).
Cheers

It can be extremely harmful, it introduces huge shock loads into the transmission. If you find you're suffering from this, one way to get rid of it is to ride the clutch slightly, not enough to actually slip but just enough to absorb the huge spikes from the transmission as the wheel slams down. Removing these spikes protects the transmission and also kills the wheel hop dead so you get more traction.
