steering problem

[Spike1211]

I have an 02 explorer 4wd, 4.0. The vehicle is very loose and veeres all over the road when driving. I have replaced the upper control arms, sway bar bushings, sway bar links, inner tie rods, tie rod ends, lower ball joints, hub assemblies, and had it aligned. Can anyone help me to diagnose what is causing it to swerve like it is?

If there is no play (looseness) in the steering wheel to the front wheels it could be an issue in the rear end. I have a car right now that the upper mount for the rear strut assembly is broken. Each large bump it takes, the rear wheel will turn a little and I have to compensate with the front until it seats back into place.

I checked my rear tires, and found my driver side tire has a lot of movement in it, so looks like I will have to replace the rear end now

With your truck being a 2002 you shouldn't need to replace the "rear end" but likely just a wheel bearing or maybe ball joint.

I was going to suggest you check the tires for a separated belt, but if there is looseness at one of the rear wheels, that's definitely the first thing to address.
