Loose steering?
 

2001 Supercrew 4x4 5.4L

Recently I just rerplaced all ball joints and the idler arm along with getting the alignment done.

It seems that the the sterring is real loose especially at higher speeds. And when I hit some bumps it seems to want to jump to one side or the other and the steering wheel really moves.

Then today I was driving and looking at the front drivers tire over some bumops and the tire and wheel really moves alot. These were decent size bumps.

Any ideas????

Thanks, Marty

Bad hub bearing. Easier than ball joints to replace but the bearing price is about $200.

see if you can jerk on your wheel.. mine went out when i first got my truck...you could literally wobble the wheel...

What do you mean "jerk" the wheel??
