When you set off wheel spinning whats it mean if the wheels "Jump" ?? What I mean is If you hear a clunk when wheel spinning could this be the driveshafts are on their way out ?

u boi racer you!

Dan, I reckon - Its more likely to be one of the wheels spinning then gripping momentarily giving you the feeling of it jumping. When a driveshaft goes……..It goes.

As a tester – try it on a wet surface, bet there’s no jump or clunk feeling then.

Am not known as a bot racer ... that is unless I am on the "strip" and this is where it is happening - just before you go to the start line, where it is all whet and where you are supposed to spin... this is where I get the clunk :S

Could be that they're just jumpin, i've had it before, apparently its more common when you increase the wheel size for some reason????

Also you'll find that it will jump more when both wheels are trying to spin...

its called wheelhop or axle tramp...it happens when the wheel suddenly grips and then stops grippping. The give is in the engine mounts and driveshafts so the wheels hop. Changing to stiffer engine mounts or filling the standard ones helps alot.
