Wheels separates from car. How to solve this?

I rigged a car in blender and imported it into unreal engine but I have an issue that the wheels of the car detaches from the car and fall’s off.

Look at the image above
that is how my car looks when I stimulate it

You have to parent all 4 wheels to the car mesh in blender before exporting

Thank you. But now I’m making a car without rigging.

You do know the wheels have to be parented to the car, it doesn’t matter whether or not you are rigging it. How else is the game suppose to know that the wheels are tied to the car unless you parent them.
PARENTING IS NOT ONLY FOR RIGGED CARS. PARENT THE WHEELS end of discussion.
Shift select all 4 wheel objects then select the car base model last, then press ctrl p to parent them to the car. Export and end of story.

Is that right buddy? End of story? As per your reccommdations…

I have parented in every combination, watched every video, exported/imported all the different ways. Bare minimum is importing body and four wheels, a wheel/body mutant and best result is floppy wheels. Also tried Chaos to no avail.

To create a rig, make sure to follow these steps before exporting:
• Your car should be facing the positive X axis, and its pivot point should be centered at the origin of the scene.
• The front wheels should have their pivot points centered within the wheels but offset slightly into the body to allow proper rotation.
• The rear wheels should also have their pivot points centered, but without any offset.
• Make sure to reset all transforms for the car and the wheels. In Blender, select the car and the wheels, then press Ctrl + A and apply all transforms.
• In the export settings, make sure the axis is set to X Forward and Z Up (this is the correct setting in Blender, if I remember correctly).
• You should also export a skeletal mesh. When importing into Unreal, make sure Import Skeletal Mesh is checked.
