Extreme frt. end shimmy TSB

[2ManyToys]

I'm working out an extreme front end shimmy that randomly occurs after hitting a bump. You have to slow way down to recover. Didn't do it with my heavy 37" Toyos, it showed up when I put on my narrower/lighter 37" BFG ATs for winter. Its been suggested there's a TSB concerning "adjustable caster shims" to correct the problem. Its only been 450 miles since the lift, so I haven't checked alignment yet. Thought I'd see if Ford would pay for the adjustable shims (TSB). Anyone know what the number might be? I've also found TSB 04-26-1 "Steering wheel oscillation after riding over bumps". It suggests tightening down the steering gear mesh load adjustment. Thoughts? Any one else have a similar problem?

can get scary at times when hitting bumps while cornering at 60mph

You know, I've been having that same problem with my truck. I figured it was due to the new suspension when the '05's came out. Steering is kinda sensitive. Corners very well though. Kinda caught my attention while going over a bump in the road and not having my hands on the steering wheel. SCARY!!! Is there a recall or TSB on it. Haven't been to the dealership lately. Last time I was there, I was getting the 05B35 reflash done to my truck.

I had very same issue with mine...found to be more prominant on the FX4's. I have 3" lift and 35" Toyos and it was not as a result of either. Nearly scared the crap outta me a few times, had the TSB done and now it is actually a pleasure to drive. Still going to add the dbl shock stabilizer due to the larger tires. GIT-ER-DONE!!!!

So is there a TSB on the front end shimmy? If so, what is the name or recall # of it? That way I can get it done and not worry about driving over any potholes. Besides, I thought that was one of the reasons in buying a 4WD truck, so you can basically drive over anything.

In the Jeep world its called the Death Wobble, It can be from several problems, I will help you narrow it down.. Check these Items out

A. Alignment (after lift or lowering)
B. Hub Bearings
C. Ball Joints bad
D. Drag Link not Parralel with Track Bar, Axle rotated to much one way
E. front axle needs to have an Adjustable track Bar
F. Bad bushings (control arms to axle, or frame side of control arms)

One of these Items are bad and finding it and correcting it will fix the dreaded death wobble
