Cylindrical constraints extremely unstable, need help

Hey there!

I’ve been working on this car chassis for a while now, but the wheels wobble a lot and make the car unusable. Video:

As you can see towards the starting of the video, the wheels wobble up and down even on a completely flat surface, which is not what I want. Here are the cylindrical properties:

(The inclination angle is -90 for the right side cylindricals and 90 for the left)

Springs:

It works by setting the angular velocity of the cylindricals.

A strange issue to note, is that if I run the game (by pressing F8) and then set the angular velocity of the motors, it works soo smoothly:

Could it possibly be a replication issue with roblox physics?
Also, I’m not using any sort of tutorial for this, everything was done by me
Thanks for help!

For My chassis I’ve used BodyGyros for steering attached to a cylindrical, for driving I use a hinge, also It could be due to the characters weight, or if your changing the torque mid game.

I’ve tried setting the characters weight to massless but it didn’t help. And yes I am changing my torque mid game but not changing it doesn’t make any difference either. For steering I’m interpolating the front attachments orientations.
