Vehicle listed above is the LS model. When start to accelerate front left tire wobbles and feels like it is going to come off. The whole truck shakes and bounces, going slow and fast. Plus there is no axle currently on truck, should there be one? Do they all come with one or not necessarily?

A wobbling tire could be a number of things. Have you done anything already to address this?

It could be the tire, wheel, hub or rotor. So we need to lift the truck and start measuring what is called runout on the hub, then the rotor face, then the wheel, then the tire. We can stop when we find the one that is out of spec. Basically if the hub is rotating unevenly then it will be exaggerated at the tire. Think of it like jumping rope. You hold the ends of the rope in your hands and don't need to spin the rope that much to get the middle of the rope to start making complete revolutions. Same idea here.

So check out this video that does a good job of showing what you need. You can rent this tool at most parts stores.

Lastly can you define what you mean by there is no axle? Do you mean should there be an axle on the front left tire? You noted this was a 2WD vehicle. If that is the case then there should be no axle going to this hub.
