07 F550 has wobble of death in steering between 30-50mph

seems to start when you hit a bump on one side.. the steering wheel starts to jerk left and right violently and only way to stop it is to slow down to about 20mph... its fine for maybe a minute or 20 minutes then does it again.. I'm assuming both front shocks are blown? I saw online the pitman arms don't go bad, i cant find play in anything by manually moving it underneath the truck.

anyone else have this happen? it is an F550 crew cab 201" wheelbase not a F350 dually... so its a little different up front, the shocks arn't the same as what all our other F350s/F250s use, they're larger i guess.

I would bet you have a bad track bar ball joint and track bar bushing. To get the track bar ball joint out you need a ball joint press. I believe you can buy just the bushing for the track bar and replace that. Hope this helps.

I forgot to mention how to look for the bad parts. First grab a buddy or the wife. Turn the key on with the engine off and have somebody rock the steering wheel back and forth (2"-3" to each side) while you get under the truck and look for any movement in the track bar and track bar ball joint and tie rod ends. If you see any movement the part is bad.
