Steering Shake Issue (Violent)

Well long story short, I have a steering shake that occurs when I go over any sort of bump in the road. To eliminate it, I have to turn left or turn right to stop the shaking (as of lately its gotten worse and is tough to stop). I've never done a trucks suspension, only read and researched to see what my truck had done to it.

It happens at higher speeds, I would say around 40+

I rotated the wheels/tires before winter and it went away for a couple weeks.

I don't know if the reason behind this issue is:

-Tires out of balance
-Hubs going out
-Worn draglink or trackbar
-Worn DSS shocks

Any help is much appreciated. If there is information you need from me just let me know and I'll do my best to answer!

Modifications are:

-Rough Country DSS Kit
-4 Link Front Setup
-Front Coilover Conversion
-Bilstein Front Trackbar/Draglink Shock
-Custom Longbars Out Back w/ Built-In Lift Blocks
-Etc.

In addition, the truck is lifted 10.5" with 20x12 Fuel Hostages Deep Series wrapped in 40x15.5R20 Toyo OC M/Ts.

The steering feels like its from a 1970 Bronco right now.

Sounds like you have death wobble. I have a levelling kit on my truck and needed major front end work done. I had the track bar, draglink, steering gear, steering stabilizer, and castor adjusters replaced.

Definitely look at the track rod and track rod joint. A little bit of play can cause this. Also, it may need an alignment. I wouldn't be surprised if your kit was an 8" that someone made into a 10" and now everything is off. Or your 4-link doesn't adjust enough to get the required caster.

Do you feel the bumps of the road in your steering wheel?

It's difficult to tell but yes I would venture to say I personally feel the bumps in the road through the steering wheel.

It didn't seem to have the issue when I purchased the truck roughly a year ago. The truck was built down in Tomball, TX at diesel legion. It has the 40" Toyo and I can do a full clock turn with zero rubbing issues. From everyone I've talked to, they say the truck is lifted right and someone really knew what they were doing.

I would like to check some of the issues before starting to throw money at the truck if at all possible?

**I also wanted to mention that the steering wheel has been off center since I purchased the truck. To steer straight, the wheel is turned roughly 1/8 turn to the left. Maybe that will help the diagnosis.

Thanks for all the help so far guys!!!

See that tells me that it possibly could have been raised higher if the steering wheel is off.... That would throw all the alignment specs off and if it was say an 8" RC lift then it wouldn't adjust enough to make the 10" drive right. If you can feel the bumps in the wheel then that also tells me that the caster is probably off, but some 4-links are known to do this as well out of the box.

Sure that would be great. It might also be worth taking it back to the shop that built it as well.
