We have covered this a bit in the other thread, however, it probably warrants a thread of its own.

As most of you may know, the SDL pulls to the right when the brakes are applied. It also has developed a "thunk" on the right front that sounds like the shock is bottoming out. However, the "thunk" does not happen on every bump, even larger ones. It appears to occur on left turns more than anything else. It almost sounds like the spring is loose and banging on something.

The following have already been replaced:

Front calipers
Front rotors
Front pads
Front brake hoses
Tie rods
Rear rotors
Rear pads

None of the above had any impact on the symptoms as noted.

Took it to the alignment shop today and had them brake it on the rack while another person was underneath. You could definitely see the RF wheel move rearward on a decent brake application.

So, what is it:

David hit the nail on the head:

The bushing that holds the swaybar in place was completely missing from the vehicle. The bar was floating in free space.

Additionally, the bushing that secures the bar to the upper arm was toast.

The "thunk" is being caused by the swaybar banging on the body during certain jounce/turn conditions.

I'll probably replace the upper arm since I have to remove it to do the bushing anyway.

The guide rod mounts appeared to be in good shape and did not move excessively on brake application.
