Vibration, helpppppp!

[travisH3]

Hey I just noticed with my truck(05) at about 65 mph, I have a light vibration and today I noticed it more. I jack up the front end and when I grab the wheel at 12 and 6. It has no play. If I grab it at 9 and 3 it barely pivots back and forth and I believe that's the vibration. So I watched everything up to the steering gear box and it looks like everything is tight until u get to the gear box. Is there a way to tighten it up or do I need a new one. My truck is for sale and I have some potential buyers and I don't want to pass problems to someone else. It would prolly go unnoticed if someone test drove it but that's not the person I am. Let me know if ya guys have an idea, if not I will drop it off and make sure the front end is okay so the next buyer wont have to worry.
Thanks everyone

vibrating should be a balance issue I wouldnt think a worn tie rod or something would vibrate.

When I'm on the high way it just starts shaking. When I jacked up the truck or just kick the tire you can see both front tires moving. Our 2010 don't move when you kick it. That's why I figured it wasn't out of balance because I'm taking the tires to get balanced tomorrow but I just came figure out why it does if some times more than others?

A 3 and 9 shake is a tie rod end check. If the tie rod ends are tight and its moving, the ends on the drag link may be worn. Either way, tightening the steering box is NOT the answer. The only time I have adjusted a steering box is to eliminate excessive slop when turning the wheel.

To check the ball joints, lift it up, put a board under the tire from the side of the truck and lift up. This uses more leverage than using your paws. This shouldn't take a lot of effort to check.

Awesome. Thanks guys. I will be checking it out tomorrow. I just want it figured out and get what ever parts replaced I need. Wheels are getting rebalanced tomorrow anyways, I have factory 20's on the truck now, and after class I will get it off the ground and get my buddy over here and start replacing parts. Hopefully we have no trouble finding it. I just thought it was in the gearbox because when I shook the tire back and forth the opposite side did the exact same thing and I couldnt point out exactly where I was hearing the noise from where it's loose. I will get it on a lift tomorrow. That should help. Thanks for the help, I will keep you guys posted

Sounds like a tire balance thing to me.
There will be a littke play in the gear box and it will cause the
truck to wonder but not shake.
sometimes (happened on my f150) the tires are out of balance just a little bit
not causing much vibes, but then you go around a bend and because the tires
run at different speeds through a turn they go out of phase and cause a bad vibe!
go around another bend and it smooths back out! Im not feedin ya a line of **** either!
dealt with that for 3 months. Finally rotated just the drivers side tires and never had it again.

That's exactly what it does, u go around one bend and it doesn't do it, you go around another bend and it does it bad. Sometime it will do it on a straight away but mostly turns. Thanks, tires will be balanced today and I will take it for a spin and see what goes. It may be the tires too. I got the 08 20's and they have 15% tread probably. Im wanting to put trail grapplers on them, put the 20's on my 2010 and the tires on my 2010 are prolly 65%.
Well I will let you know what goes

Wooohhoooo! Only one rim still had a weight on the rim and it was on the back, other three rims all threw the weights off. Drove on the highway from 55-80 and no more shake. Thanks alot, I appreciate everyone's help
