mine make a noise now , but the faster i go it makes it, its kinda a vibration too,its the fort left wheel that it's coming from, but i can hear and feel it the most at 60 what could it be a u joint, sealed bearing somthing in braking, i also took it out and weeved side to side to load eack side of the suspention and drove in circles too and nothing realy happend as in noise so i dont know whats up. its making me mad.

 

like metal on metal? or just a rattle and can you feel it in the floor board?

 

like just a rattle that you can feel threw the floor, and its just a little one

 

Is it a 4x4 or 4x2. That makes a big difference in what the sound could be. I think in order for anyone to help, you have to provide more info.

 

Knuckle U-joints and wheel bearings are not unheard of. The Knuckle joint failure is more common on 1/2 tons, while I've seen the wheel bearing more on 3/4 ton trucks. Obviously, if yours is @WD, it's not gonna be a U-joint.

Jack up the suspect wheel and see if it has play (grab top and bottom and try to wiggle it). Also, spin the wheel and listen carefully for a faint growl. If loose or noisy, it's gonna need bearings/a bearing. (if it's 2WD, don't condemn the bearings just for slight play).

If it's a 4x4, turn the wheel all the way and rotate the tire. Bad knuckle joints will usually pop and crunch, especially when turning.

From your description, I'd suspect wheel bearings. Never heard a knuckle joint make noise going straight at highway speeds.

All that said, be sure it's not a tire issue. If the tread looks more like a saw blade (feathered), rotate them and see what happens.
