my upper and lower control arms went down. its an 01mountaineer 5.0 AWD the nut from the lower balljoint is now sitting on the inside of the rim. i wasnt driving when it happened but i had justreplaced the axel with a used one. lowerball joint and tie rod are new. is it the upper control arm? axel? an adjustment? and can i drive it slow just to move it? thanks Trish

 

Don't drive it. You will do more damage. I don't think it will even want to move or turn without a lower lbj. And have a word with whoever put the axle in. A used axle at that. A new one is less than $100, even less after you return the core. You must have heard the front end making noise or not driving right for a while before this, no? If the parts are new than it was a VERY faulty install. You may have easily been killed if the ball joint gave out on the highway. Have a good mechanic put it back together for you. Replace anything that was damaged or in need. Good luck.
