Problem with car tutorial

I’ve been following this tutorial to try and build a car in roblox studio.

I managed to get the car to drive forward and backwards but was unable to get the turning to work. Whenever I tried to turn the TargetAngle of the HingeConstraint changed but the actual angle didn’t fluctuate at all and stayed at zero. I suspect that the collision is wrong somewhere but I can’t figure out how to fix it.

Here is the world:

Any help is appreciated!

Update: I found two welds that were stopping the car from moving.
