I have a vibration in the front of the truck that was VERY loud and vibrated the steering wheel, almost deafning is so loud. It only happens between 50 and 65 mph and it is speed dependent and accelerator dependent. When I push the gas it to accelerate I feel the vibration if i let off it mostly goes away. Now I know that I HAD a bad steering stabilizer at that time, I was hoping that when i istalled my new dual stabilizer setup that it would help the problem, also it got new ball joints and u-joints and I pulled the front drive shaft just to rule it out. It got an alignment and balance with the new tires and the entire suspension is new. The dual stabilizer setup did reduce the vibration greatly but i can still feel it and definitely can still hear it btn 50-65mph. Oh yeah i also installed a new steering box too. Basically the same vibration before all the work is still there after all the work and the dual SS did reduce but didnt eliminate it. Anyone have any ideas of what to try or investigate next?
