Prismatic joint for springs side view car

Jan 18, 2013 at 9:12 PM

Hello, I am trying to make a car in which I have 5 bodies. One is a rectangle which is the main body of the car, 2 are axles which are boxes, and 2 are circles which are the wheels. I have created a prismatic joint between the axles and the main body, and revolute joints between the axles and the wheels, I set limits on the prismatic joints (axis, and translation limits), it seems to be working fine except that the axis limit on the prismatic joints do not seems to work, I set the axis to be straight up and down, yet the wheels move from side to side. If anyone knows what could be causing this that would be great, thanks.

-I have followed many tutorials on car with springs but the same issue is that of the wheels moving from side to side. As if the prismatic joints were breaking.

Are the tired "wobbly" or do they move side to side on a straight line?
