Steering Wheel Oscillation 05 Sd
I have a 2 customers with SD an 05 and an 06 both are 6.0L. One truck has a 8" Fabtech with 2.5" coil spacers and the other has a 8" Fabtech They are both four link suspension kits and both have 3 steering stabalizers. I have already performed TSB 06-015-1. I have also replaced the track bar ball joints, dropped the tracked bar braket down an additional 3" and made new adjustable track bars.

Sorry the both trucks have really bad steering Oscillation @ highway speeds. The steering will shake uncontrolably untill you slow down under 45 mph. I have already talked with Fabtech about this problem.

Sounded strange to me too. I had the tires rotated and balanced with no change. Steering wheel would shimmy anywhere from 55 mph up. That fixed mine. It wasn't just in slowing down like yours though.

This problem started 20k after lift was installed. It is not a tire balance issue, it is a vibration over 60 after hitting a bump or going over an over pass. This is a Ford problem not a lift problem.

I'm not sure it IS a Ford problem....STANDARD DISCLAIMER: I'm not a mechanic...I'm a truck owner and shade tree mechanic.
Any time you start modifiing the suspension....you're creating the potential for problems. According to the post, everything is good until you hit a bump or an overpass. Just one guys opinion, but I would point to the lift kits.

It is my honest opinion you will find that the steering boxes are to blame.
The spool valve springs aren't strong enough to keep the rebound from getting the steering box into a resonation that won't quit.
I heard from one guy who went back to the dealer 3 times or more, they kept changing the box until finally found one that didn't do it.
You might want to adjust the lash in the box first.
Also, have you tried a steering stabilizer (or two)? I know, many consider it a band-aid, but it would be interesting to know if it helped at all.

It's not a lift problem. I had the same problem with a stock truck. I have a 2005 f350 4x4 dually. What you are talking about is the death shake. I had this problem and everyone was scrathcing their heads. Ford can kiss my butt on this one. I have always been into suspension and sat down and took some measurements and studied the suspesion and steering on the front end. I came up with a bad geometry problem with the factory stabilizer. The location it is installed causes it to do the opposit of what it is there for. being so close to the steering box causes bumps in the road to be able to manipulate the steering very easily. If you want to fix this buy a dual steering stabilizer and put in on the truck. Buy one that bolts onto the axle and attaches to the steering linkage between the front wheels. You will notice a difference. I promise. Ford needs to go back to the drawing board on this one. Forget all the crap about checking your tires, shimming the steering linkage, or the replacing your steering wheel. The best kit I have found for this is the fabtech dual stabilizer kit. Hope this helps you man.

On alot of the late models the stabilizer mount is located at the linkage close to the pitman arm. Way to close. On some of the early model superduty's 99-03 and the occasioanl few late models the stabilizer is mounter between the lower linkage and the axle. Not too many of those had the bad shake if any.
