If your rear wheels migrate out backwards and fowards when you do the roll test is your drill job pefect or could it still be off enough to make the car wiggle
 
well this car still wiggles if you put more steer it just slows the car down..its gota be something else bad drill job rear axles that arent perfectly straight or weight problem..i dunno

Axle diameter too small, wheel bores too big, not enough cant in the rear axles, not enough thickness in your prep film.....

Is it a scout car or your next league entry?
 
First I would check the alignment, try to use a square and calipers to check if your rear axles are straight/parallel with each other. Your trying to check for toe in or toe out and if you have the back end racked one way or another. If everything checks out good and straight, i would suggest trying to remove some weight off the rear and moving it up to your DFW side. You might not have enough weight over the font wheel to hold steer.

I forgot to ask first if the rear is just moving or the hole car? If its just the rear its either miss alighment or the wheels.

Good luck

Sorry TRE, i'm half a sleep this morning and i just went back and reread your first post that you are just roll testing the car. I thought you were having this problem on the track. so it would be hard to see if it was a steering issue with out track testing.

I would also check cant, not sure how if one had more or less cant it would effect the car.
