Often the TIS replacement is because the part is installed torque to yield but I don't recall that being the case. I reuse most suspension nuts and bolts that are not torqued anywhere near yield replacing only when they show wear.

CV wear can also cause that type of shake. Cured my wife's X5's jitters. In her case was amplified greatly by some stones on the stiffening plate.
