i have a 96 f150 4x4 and and was wondering if anyone else has experienced slight vibration at about at 15mph and 25mph but only at those speeds. can mainly feel it but seems to me to be frontend related because even coasting down a hill i can feel it at those speeds.... truck is lifted with 33s single cab short bed... any info would be greatly appreciated thanks

 

Check u joints wheel bearings and ball joints

 

And tires. If they're old or oddly worn, tires can really cause some head-scratching.
Do you know the history? Did you do the lift and tires, or did you buy it already done?
