We also have our coach aligned after new tires.

The shocks, springs, air bags, etc are not going to cause a vibration. Waste of money if they are good. Take it to a different tire shop and pay them to balance the tires, and yes, definitely find one with the Hunter Road Force balancer mentioned previously. When the other shop either fixes the balance or finds a bad tire, then take the bills back to the original installer.

What actually shakes? Is it the steering wheel that you feel shaking or does the shaking come from the floor as noticing shaking in the seat? If coming from your seat it is more likely an out of round tire and you won't fix this by balancing the tire. Have someone follow you in your tow car and watch your tires on a smooth hiway and see if they are bouncing up and down. That would indicate an out of round tire. Also as Ron said, jack tires off of the ground one at a time and spin by hand with a wood board underneath and measure the distance from the OD of the tire to the flat board. Is it an 1/8 in or more? If so see if the tire has been seated properly sometimes just rotating and reinstalling will fix this problem. If not the only other way to fix an out of round tire is the true the tire where they actually shave some rubber off of the high spots to make it round again. If the ride was good before the new tires I would not change any other suspension parts but focus on getting the tires right.

These tires were balanced with sandbags. Could this be a culprit? Also can they be road forced balanced even with the sandbags?

Just to clarifiy, The 2 tires they replaced were the drivers side rear. The shake does feel like its from the rear. The shop said they had the truck off the ground with the tires spinning and could see the two rear drivers side tires “hopping” so they swapped them. Again, it didnt make a difference.

I wouldnt be surprised if it was u joints. The shake seems to change with resistance. For example, its much worse when im coasting, but seems to clear up a little during acceleration. Also it wont shake too bad at all at 60, but if i go up to 70 the shaking fit begins and i have to go all the way down to 50 to make it stop. Its really weird. Almost seems like rear end to me now that i think about it.

Im also in an urban area and its hard to get the rig up to speed. Its a chore to drive it all the way to a highway which i why i think the shop is butchering the diagnosis.

Have you thought about getting a four wheel alignment? This is where the rear axle is aligned with the front axle so that they both roll down the highway in perfect alignment with each other. Not too many shops can do the four wheel thrust alignment so they will just tell you that it is not needed and all that you need to do is just the standard front end alignment.

Alignment will not cause shaking. Tire wear yes, shaking no. I would suspect first balance, second the rims being out of round or bent. Possibly due to the tires not being mounted correctly or some sort of debris not allowing the rim to be mounted to the vehicle hubs in a perfectly flat position.


My advice is worth exactly what you paid for it.

I'm for lifting the rear wheels yourself, well not yourself but with the
jacks
let the wheels spin slowly and watch them.
You may be able to see a wobble or out of round tire.
Look at the wheels too, one could be bent a little.

Yeah if those bags don't break open and let the material
out they probably won't balance, also if there is very much
moisture it may clump up in the tire.
Are you sure when you say sandbags, is it really sand?

I think he means Equal which is a powder,very common for truck tires. Why would you suspect U joints if you did not have this problem before the tire change?

He may also have used the balancing ceramic BEADS which also come in bags and will not clump or be affected by moisture and do not require special valve cores.

I figured beads were what he meant but I have heard of people using BBs or those plastic pellets the kids shoot
I bet dry sand would work too.
Many things could balance at least for a while
Equal powder is the one I have heard could clump.
