Hey need some help. I have 93 f150 ext cab 4x4, since I have owned it, around 60mph it starts to vibrate and shake. I put new tires on it (33x12.50x15's) not aggressive tread at all. So what do yall tahink that it is. I mean I can not go over 60 for fear of truck shaking apart. Also put new brake pads on as well.

 

Any play in the steering components? Are the tires Balanced.

 

Check your U-Joints and the balance on the tires.

 

Balance on tires boss

 

Ok, thanks I will get ujoints and tires balanced again. I didn't think that it was rotors either because it doesn't shimmy when braking. Could it be warped driveshaft? If all else fails I will look at buying way smaller tires. I already went down from 35's to 33's. Thanks again.

 

Should be.balance issue. At that speed. Roughly 90 to 100 Kms an hour. Balance would cause shakes
