So I got new stock tires, balanced, and alignment.
both tires at 37psi
Bearings are fine
steering rod ends and track bar ends are fine
Drag Link and Pitman bushings appear solid
Vibration happens between 45 and 60 mph, and only when I let off of the throttle and decelerate thru that range.
Happens in any gear, or in neutral. But this is not just vibration, it is serious back and forth in the steering from wheels to steering wheel, like if you are going straight the steering wheel goes back and forth from 10 oclock to 2 oclock on its own...you can't even hold on the force is so great......have to jam on the brakes and get below 40mph then it just vanishes.
Its so bad I've blown out two steering shocks in one week.....when shock is on, and not blown, you barely feel it.
Once blown, or shock removed, its violent.
Interestingly, it gets progressively more and more violent and I can barely hold the steering wheel. My wife drove behind me and said front wheels are wagging back and forth while car going straight!
any ideas?? had it on the lift yesterday, and there is no play in anything except between steering linkage and steering wheel.
Went off-road all day Saturday, drove home 2 hours no problems, no shakes, then next day, all crazy like out of nowhere!
Its not driveshaft related (not that type of vibration, and shafts are checked and fine)
