Why is my car wheels not working right?

You can write your topic however you want, but you need to answer these questions:

  1. What do you want to achieve? I want my Wheels to be placed correctly

  2. What is the issue? Its not working

  3. What solutions have you tried so far? Youtube
    I made a working car and everything works good besides one thing which is the wheels. The wheels get misplaced everywhere for no reason. There are no errors or anything can someone help me?
