So in the end what do you think was the cause of the problem? The warped rotors or drag link?

 

After replacing the drag link I'd definitely put it on the alignment rack. Counting threads/tape measure is only good for getting toe "in the ballpark" and will not get your toe set accurately in itself.

 

I think it was a combination...

The rotors definitely were what was causing the pulsing and then started the front end wobble. Worn tie rod ends on the drag link were allowing that pulsing to translate into a wobble.

Stops nice and smooth now...

 

Definitely going up on the alignment rack on Monday. I only drove it the 7 miles home and will only drive it the 7 miles back before it gets aligned.

Next up, I need to determine the shock setup I'll go with. Looking at the Old Man Emu 2" Lift with heavy duty front springs and some 2" Spacers for the SLS in the rear.

 

Discovered that the track rod was also bad, so I replaced it as well. Huge difference...

Turned all four rotors
Replaced Drag Link
Replaced Track Rod

Also installed new rear brake pads...

Next up is the shock replacement and a decision about a possible 2" lift...
