All the blueprints that I made were made from watching this 3 Videos https://www.youtube.com/watch?v=qOe3lYCA1YA https://youtu.be/Y6TO3Fg-gsA https://youtu.be/Bc-o6-pZG44
I didn’t know how to do any blueprints
Here is how my steering blueprints look like

For the constraint stability one of the most important things were this settings on all the truck parts

And the Constraint Projection Values are set to 0.1 for the Projection Linear Tolerance and 1.0 for Projection Angular Tolerance
Another very important thing is Sub-Stepping. I set 16 steps and Max SubStep Delta Time to 0.016
Initially the Max SubStep Delta Time was set to **0.016667 **which was perfect at 120 FPS but when I dropped the frame rate to **60 FPS **the wheels were getting pushed into the ground and jumping around this problem got fixed by changing the Max SubStep Delta Time to 0.016
