Car bounces around because of CylindricalConstraint

I’m making a cart ride game inspired by OneSkyVed’s “cart ride around nothing” and I have a basic cart chassis. The problem is that it bounces around like this when I play test the game: https://gyazo.com/cb1b75a65e4643ed28aaa42f03799635. If I disable the CylindricalConstraint it just lays like this:

How can I make it so that the CylindricalConstraint doesn’t bounce the cart around? Thank you.

I think this is because the wheels are too light, causing it to bounce. Maybe applying more density may fix the problem

As @Callum_Cloth suggests its both the wheels and the main part need more density given the force you have set the constraints at. Also make sure that the attachments for the constraints are facing the right way.

I set the density to 100 but it’s still bouncing. How can I decrease the force of the constraint?

This is an excellent video by sleitnick on rigging car with cylindrical constraint, jump to 3:05

My cart uses axles. They were just transparent in the gif.

What constraint are you using for axle?

The vid shows you how to set the force of the cylindrical constraint.

Ok have u tried lowering the force of the springs?

Also when u increased the density to 100 did u also increase the density of the wheels?

It’s not because of the springs, it’s the cylindrical constraint. I increased the density of both the body and wheels to 100.

I ended up completely remaking the cart
