    I am trying to figure why this truck is shaking. Just bought the truck, and it has a shake in the front end. I can feel it in the steering wheel starting at around 45 mph, gets worse around 50-55 and then seems to get a little better around 60-65. I figured it has to be an out of balance issue, so I bout some stud sleeves to align the wheels on the hubs. I had the wheels off today and cleaned the inside of the wheel and stud holes, plus the brake drum where the wheel mounts to it. Got the brake drum centered on the hub and the wheel centered on the drum with the alignment tools. Took the truck out for a test drive and while it was a little bit better than it was, it still shakes. Is it possible the tires are ruined and I need to replace them? The inside of the tire is wearing a little bit more than the outside, but they are both at about 75% tread left. I don't want to waste money throwing parts at the truck, as I am just starting out and need to save as much as possible. Any help anyone could give would be appreciated greatly.

    Thanks,
    Cliff

    Your shake is either an out of balance, or out or round steer tire. So far you have done well to make sure the rim and drum are properly centered. The tire itself can be mis-mounted on the rim and running out of round. The tire could also be worn and running out of round. You would need to jack the steer axle and spin up each steer wheel and watch for the tire going up and down as it is spinning.

    Thanks for your response, I am going to jack it back up tomorrow and take a really good look at the tires spinning. It seems like it is wobbling or like the tires are fighting each other. There are some pretty stout weights on each of the rims, should I get the wheels and tires rebalanced, or remounted?

    I would have them rebalanced/checked. You could have a broken belt in one which could cause a shake.

    Check the front end while you have it off the ground. Worn out king pins, tie rod ends, etc.

    Everything seemed to be tight when i had it up on jackstands yesterday, i couldn't get anything to wiggle. I will check it over again today. I am thinking it must be tires out of round or broken belts.

    Too many tire experts on here, but here is my thing with wheel balancing... If you install a quality name brand tire and have it properly installed you should never need any weights. You cannot feel anything under 6 ounces. Anything more than 6 ounces, something is wrong with the wheel or tire! I see a lot of tires that are quickly installed by the tire guy with not enough lube and they just do not sit square in the bead. The tire is now running out of round. Weights cannot fix this. The tire must be mounted correctly. Once the tire is square to the rim, and the wheel is centered on the hub, 99% of the time she rolls smooth as silk! If the tire is cupped, the tread is fluctuating and the tire is not round in shape. Again, weights cannot fix this. You can see the fluctuations in the tread of the tire as you spin it. Replacement is the only correction. If you see a wheel with 10 ounces or more on it, the tire is junk, mis-mounted or improperly set up!

    I just ran into the same situation that Heavyd mentioned. We have a guy who doesn't like the Myers lube. Installed steers dry and it didn't seat right on the rim. Just kicked of to a lovely monday morning doing a job over that he just did Saturaday.

    Spin the tires and see how much wobble they have. A little is normal, tires are not perfect. I found with our Internationals that have the rubber shackle bushings, they are more sensitive. It seems that rubber shackle bushing amplify any out of balance making them a little more sensitive.

    Okay, just spun them up and the passenger side is noticeably moving back and forth, there is a movement every time the tire goes around. The driver side is worn a lot more than the passenger side and is noticeably out of round. The driver side has no weights on the wheel, but the passenger side has 10 oz. on the outside of the wheel and either 6 or 8 oz. on the inside of the wheel. I think the tires are the problem for sure.
