Hi, I bought a ULM for my son recently. The car was running ok until a few days ago, we notice that its not turning to its right, also going forward/backward was not smooth either. After inspecting, I realized that something inside the front suspension, particularly something connected to the tire, is either broken or detached. the wheel is making a lot of noise when rolling, not able to turn, and also when holding the wheel, something inside is turning but not the wheel itself. I would like to take that part apart and see if I can fix it if nothings broken. I would appreciate any detailed guideline/instruction on how to do it as well as any do’s and dont’s. Thank you.
