A little play in the tie rods, track bar, wheel bearings, or ball joints will NOT cause DW. It sure doesn't do anything to limit it but by itself or all together none of those will cause DW to start. People that tell you that are looking to make money addressing the symptoms not the source, or, they have no clue how the suspension system on these trucks work. If you had enough slack in those parts to cause DW you would be herding it down the road not driving it. Unless it is totally trashed, the dual stabilizer will stop any movement in the tie rods and even BJ's that would start a shimmy. It won't stop the movement in the track bar but that will never be completely gone as it is designed to have some.
Short and simple, DW is uncontrolled rebound that turns in a self sustaining oscillation of the front axle. The axle itself is moving in 3 dimensions at the same time and individual sides are moving almost opposite each other in 2 of the dimensions which perpetuates the oscillation. It is actually bouncing off the stops in all the bushing areas, track bar and control arms, plus compressing the suspension parts beyond what they can damp out; springs, tires, and shocks. Rebound happens in 2 areas; spring\shocks and tires. It either of those 2 areas are soft or incapable of controlling sharp direction changes you WILL have DW, not a matter of IF, a matter of WHEN. EVERY other part in the steering and suspension can be worn past safe and it will NOT go into DW as long as the tires and shocks are capable of controlling the rebound.
Your choice, but, you can find every forum littered with stories of rebuilding every component on advice from the experts and still have issues when they simply cannot believe they super duper special shock or their special expert advice tires are the real problem.
