I haven't been on here in quite awhile but my 06 QC Cummins wobbles at low speeds up to about 50-55 mph and almost goes away at 60-65.You can still feel vibration but it quits when you let off the throttle. Particulars are 59,600 miles, stock suspension, Cooper Discover ST 33x12.5 tires about half tread left and balanced. Steering wheel shakes really bad(trying to get a video with my phone) up to about 40-45 mph. I bought this truck new, and dealer said nothing wrong on the recall. I really don't have time to read through all the posts about this, Thanks in advance.

 

something must be loose or wore out, the problem could be anywhere from a bad sector shaft bushing(steering box) to an outer tie rod and anywhere in-between, best way to go about it is have someone turn the steering wheel back n forth quickly (engine running) and someone else lie in front of the truck to inspect all moving parts and bushings..

 

Check tie rods ball joints.

 

check hub bearings also.
