Death Shake

[SUPERDAVE1264]

07 F350 dealer 4" lift oversize BFG 34000 miles, just recently discovered the Death shake only when I'm towing my 5th wheel, It's at the dealer now and they tell me the upper and lower ball joints are worn and that my tires have about 1/2 life left witch contributes to the shake. They are going to replace the parts under warranty,I don't think its going to fix the problem so I'm thinking I need to beef up the stabilizer. Can somebody tell me what is best stabilizer and who sells the complete kit. I want to have the two that are in front of the axle and the two or preferably three that replace the factory one on the steering arm.

the problem with your truck isnt ball joints ,there is only one thing that will cause the death shake , that is the tracking bar , on a 07 model the bar and the joint that the passenger side end bolts to that looks similiar to a ball joint needs to be replaced , steering stabilizer has nothing to do with it

since my truck's in the shop, It's hard for me to picture which bar your talking about. I'm guessing that its not the bar coming off the steering box but the next one coming off that?

Can you describe the "shake" a little?

Does the steering wheel shake? Do you have to slow down to get it to stop? Does the entire truck shake? Only at certain speeds?
Etc...

the bar that comes from frame on drivers side to rear end on passenger side and like in said it bolts on the passenger side to what loks like a ball joint

Scuffy is right on the money!!

Your truck has the coil sprung front suspension, and the whole front axle is located side to side with the track bar (or panhard bar to be technical). If this bar gets loose from worn parts or loose mounts, it allows the front end to shift side to side violently, producing death wobble. It was very common in Early broncos and F-150's. The cure was poly bushings and locktite. Just have the worn parts replaced and you should be fine!

The shake happens around 65-70 mph when I hit a bump or rough bridge,I looked out the window the last time and the tires where shaking left to right even though it felt like I was bouncing up and down. I have to slow to 15-20 to get it to stop.and yes the steering wheel goes crazy also.

track bar/panhard bar , whichever you want to call it is your problem, ball joints wont cause death shake

My sisters 07 did this and it had BFG All Terrains and once she got rid of them and got Toyo's her truck has been fine ever since.
