Suspension shake.......

[C MY 4D]

Well this is a grand way to introduce my self....... I recently purchased an 05 F350 with approximately 4" of suspension lift. I wish I knew more about it but the dealer had no clue what it was nor is there any markings.

Over the last couple of weeks when making a left turn between 40-55 mph if I hit a bump the truck will go into a violent shake. I have lifted the truck and checked the ball joints, hubs and tierods. All of them seam to check out fine. The only thing I can think of it being is the track bar bushing. Has anyone else experienced this problem?

my track bar bushing is gone but all i get is a bump sound when i turn..... no violent shake.... has it been aligned?

If your running bigger tires and stock steering stabilizer that would cause the front to shake bad... mine was terrible.... then i put a dual stabilizer and have had no problems since.... seemed to really help.... alignment helps TOO!

They are 35x12.50s and there is a dual steering stabilizer on it. To accurately define a violent shake it feels like 10 guys rocking the truck back and forth violently. The problem doesn't go away until I come to almost a complete stop or mash the gas to transfer the weight to the rear tires.

I'd check the trac-bar bushings. I've had that problen several times. Do you have a sway bar?

Cool.... I have to go buy some bigger 1/2" tools. The 1" socket doesn't even come close.

One other possibility.... was the trac-bar dropped down when the lift was put on. If not you could be encountering bump-steer.

Track bar bushings or if it has a drop bracket for it check the bolts for that.

I'd have to check.

It does have a sway bar.

As for it being bump steer I highly doubt it. When I purchased it, it rode great. It has just started this problem and is progressively getting worse.

I gonna get the tools to drop it tomorrow and get a better look.
