Death Wobble - Daystar lift

[bennyboydeisel]

Just purchased a new used 2010 350 with 23,000 on it. Previous owner installed, from what I can tell, Daystar spacers in front, blocks in back, rancho shock (maybe just stock), and an adj trac bar. Truck has stock tires

Has a terrible death wobble / shimmy whenever you hit a bump at about 40 -50. Dealer said it was the castor - two days and $400 to bring it barely into to ford spec - same problem only slightly improved. Tech says the only way to remove the wobble is bring the truck back to stock @ $850 in just parts.

Could it just be bad bushings on the trac bar? Last thing i want is to take the lift off and still have the same problem.

Dealer supposedly checked all joints for tightness, stabilizer, and did an alignment.

Any help would be great.

Add a dual steering stabilizer kit, they mount to the tie rod which is a much more effective setup.

I had terrible death wobble when I added my Procomp lift, I changed out the stock stabilizer with a Rancho and it was just a little bit better, then I removed the stabilizer from the stock position all-together and added a dual stabilizer kit which completely solved the death wobble issue!

Get some caster cams from Icon they should get you back in specs that is your problem! I have 3.5" upfront icon bar no issues at all!
