IMO, there are allot better set ups out there. A quality single stabilizer, like Falcon, Fox TS, OME, Yeti, Factory OEM, the list goes on and on. There is a bunch of better options than your current set up.
Torqued every time! If you over torque it, you stretch the bolt, causing failure. If you under torque it, it comes apart, causing failure. There is a reason for torque spec's.
If it was me, I would not do a thing until the steering box is replaced and the steering is correct. Then I would do the suspension and smart steer parts, alignment, wheels and tires, then the calibration adjustment for the speedo. JMO
Got mine repaired yesterday, it is a huge improvement! The truck actually tracks straight and doesn't wander at highway speeds. Now I have to relearn how to drive it, no more sawing the wheel back and forth to keep it straight. :like:
