1999 F250 Super Duty feels like warped rotors but not
 

I have a 1999 Super duty 7.3 diesel 4x4 that has recently started to feel identical to warped brake rotors. I changed the front rotors and still have the same problem. The brakes pads are fine and the brake fluid is up to level. It seems to get worse as the brakes warm up.

Any suggestions? :-huh

Hey, did you ever answer this problem. I got the same on my 05 F-350. About to by slotted/drilled rotors for all 4. got any advise Rick

I changed out my sway bar bushings, front and back, which improved it somewhat but I noticed that I have some slop in my pitman/drag arm link end and the tie rod ends. Far as i can tell they are factory originals and with nearly 160,000 mi I suppose it's about time for a change. I have a new set of tie rods just need the new drag/center link.

Might be worth a check on your part.

Youre on the right track. Regardless of vehicle if your tie rod ends start to go they will shake like Beyonce when you brake. Swap them out and you'll likely fix your issue.
