OkIs the shake happening at highway speeds or when making turns, like into a parking spot?

no
Expert:  Mike V. replied 8 months ago.
So, if it doesn't shake going down the road and it doesn't shake when you turn to pull in someplace, when exactly does it shake?
Customer: replied 8 months ago.
yes it shakes when driving down the road, and if I hold steering tight it stops shaking
Expert:  Mike V. replied 8 months ago.
OkIt is possible there is an issue with the gear box, however I would first balance the tires. These big tires can lose balance fairly easily and there has to be some play in the gear box and the drag link and idler arm to absorb it so you don't feel every little imperfection on the road.If balance doesn't help, then the tie rods, idler, drag link and pitman arm all need to be inspected to locate the problem. Since there are more then one possible issues all will have to be looked at and inspected to determine the cause. Normally if the drag link is the problem it will wonder going down the road. It sounds to me like you might resolve this with a balance.Please let me know what more I can do to assist you today.

no don't want to change phone call if I grab steering coloum it shakes down to gearbox
Expert:  Mike V. replied 8 months ago.
No problem on the phone call the site sends those automatically.I think I understand now what you mean about shaking the column to the gear box. Does the gear box leak any power steering fluid from the top seal?
Customer: replied 8 months ago.
no it doesn't leak
Expert:  Mike V. replied 8 months ago.
Ok, it is possible the U joint for the steering shaft is where the shake is coming from. Some used a smal U joint, others more of a pad. I can't really be sure on yours. If this isn't where the actual movement is, then you might just need to adjust the worm gear a small amount. You have to do this just about 1/4 turn at a time. If you look at the gear box, you can see a nut with the slotted grove in it coming up through the center. Use a flat head screwdriver and hold it in place, then loosen the nut. Turn the screw clockwise, 1/4 turn, then tighten the nut. This should tighten things up. If you over do it, then it's not going to want to return to center automatically. If that's the case, back it off a small amount and try again.Not leaking is a good sign.
