Hey, I posted this yesterday but didnt explain it much. I am a new owner of a PSD. 250 99 XLT crew cab. 130 K. I have noticed when i break harder it feel like the breaks are pulsing. It only feels like front drivers or passengers is doing it. Also when i hit approx 60 mph I feel a little shake up to like 65 70. At first im thinking warped rotor, out of balance tire. But im thinking maby a ball joint? Let me know what you think dudes. Im a stang guy, all this truck stuff is new to me.

 

When you the shake from 60-70, is that under braking or just cruising? Your bearings could be worn, but your tires could be out of balance too. If it's under braking, then I'd have to say that you have warped rotors.

 

it could be warped rotor, but normally you would feel the shake/vibration evey time you apply the brakes not just during a hard stop. it may be the ABS activating

that sounds like tire balance
