well here is an update, still not fixed after the following!

1. Rotated tires
2. New steering rack
3. new rotors

What else is left? could it be the hubs?

 

more than likely you have tires that are out of round.
They will balnce on the machine fine but if out of round will cause the exact symptom you describe.

 

RE: Daimler Technical Service Bulletin # 22-005-06
Shaking occurs when a portion of the vehicle has a mechanical resonance frequency which receives energy from another connected source. This could be a multiple of the shake frequency, not just the identical wave frequency. e.g. The front end resonant frequency might be a multiple of the Tire rotation frequency or the engine / drive frequency.
The only solution is to change the shaking section (Usually the front-end suspension) frequency. This may involve significant modifications. The dampner appears to be a major factor. Use a new dampner with different characteristics which will dampen instead of amplifying the shake / vibration frequency of the front-end assembly.

 

I still have this annoying wobble, it can't be the tires out of round. The reason I say this is, if I am sitting at a light, take my foot off the brake without stepping on gas and it slowly starts moving I can see my wheel go back and fourth when I am trolling with no gas. Could this be a hub assembly?

I have new rotors and steering rack.

 

I got the same problem....just rolling I watch my steering wheel wobble back and forth. I changed both my hubs to no avail......

 

Maybe one of the front axles are seized. Put it up on 4 jack stands , put it in four wheel drive and watch the wheels while someone presses and releases the brake, while it is in gear.

 

i just had this same problem, when i was cruising on the highway the steering wheel would shudder terribly and the entire truck would vibrate around 60mph +. the dealer replaced the right rack and power steering pump and one of the belts in my rear passenger tire let go, so i put new coopers on and the truck is back to normal. i also got an alignment done, that could be the issue too, check the alignment and bring it to a reputable shop.

 

[QUOTE=boom38;1432849]I have a 2004 Ram 1500 4x4 with a bad steering wheel wobble when driving. It goes away after 100km/hr. I have been doing some reading on the forums that it could be rotors, but wouldn't it pulsate worse when I step on the brakes? cause this truck doesn't when I step on the brakes.

Could it possible be rack and pinion?

I have rotated the tires and am running 35lbs air in all 4 tires. Still the same wobble.

Any other things to look for?

It is the steering stabilizer is bad.

 

Jack up the front, and inspect all the steering parts. Could be almost anything. Tie Rods spring immediately to mind though.

 

Wheel wobble, I read over and over about tires being out of round thinking that’s crazy.
so i took it to get balanced and sure enough the band inside the tire broke .
Thanks for the help
