Ask the dealer if they will take a set of tires off a new truck and put them on yours and test drive it. That way they can either rule out or blame the tires for the problem.
I had a '95 Ford pickup that had a shaking problem that felt like a tire out of balance. It turned out to be the torque converter.
Well before going to Tires Plus for a road force test with the balancing machine GSP9700, I decided that if the vibration was causing the left side of the bed to shake, that if I put the LR on the RR and vice versa, the problem should present itself on the RR now. I will know tomorrow after drivng 30 miles to work and in the speed range that causes it. Does anyone think that a tire balance for a tire to spin one way might actually not be effective since it is moved to the other side and ultimately spinning in the opposite direction it was balanced for? Any thoughts?
As far as changing tires/rims with a new truck, I thought about that. I am not sure if they would do that, however, they don't like having a vehicle back for an ongoing issue. Afer this road force test ($25 each tire) I will know for sure. If they come back and everything is fine, I am going back to Toyota and see if they will do that. They would be 2007 rims/tires, but it shouldn't matter.
Yeah, I alredy checked the tread pattern and the inside tread goes one way, and the outside tread goes the other way. that is the first thing I looked at. I haven't had a tire on any of my car/trucks that can't be moved over to the other side. I didn't see as much bed shake and vibration, but it is hard to guage if on the other side because it was dark out and I couldn't see the bed. This afternoon after work will be the true test.
Checking the direction of the tread pattern isn't the best way to make sure the tire is not uni-directional. It should specify on the tire which way it goes. It would look something like this.
Just want to make sure you don't make any tires come apart.

No arrow or any language that tells me they are for only "one way" usage. However, after driving home, nothing happened on the right side of the bed. That side didn't shake but the left did. I know both tires are slightly off. Maybe the left side of my truck is more sensitive to vibration? There is no grease or signs of shock failure.
Well, I got them road tested and the front tires/rims passed. The rear two however, are a different story. All 4 tires are fine, but there are quesitons about a few rims. One rim failed and with the tire, it still failed. He moved that one to the right rear. The other one the tire doesn't fail, nor the rim, but when you put them together, they just pass. Pretty close. That didn't make any sense. That one is on the LR. The back two had a lot of weight added. I drove it home, and the right side is calm, but the left rear is horrible still. I am starting to think something is seriously wrong with this truck since the RR is where the worse rim tire is according to the tech. Unless he got his notes crossed, he said I probably really won't feel anything, but I do. I am calling him and Toyota tomorrow. I think the 4-sale sign is going up.
Dude, MAKE your dealer put some new tires and wheels on your truck then be done with it! After all you have been thru, I would NOT leave the dealership untill I was satisfied. I've been following this thread quietly, and now I'm pissed off for ya man! Get Toyota Corporate involved as well, they should at least help you get the problem nailed down.

I don't think the dealer owes Nikon876 any tires, his truck is out of warranty (unless he purchased it used there and had a X day used vehicle warranty) and is already on non factory tires. I do think they owe something for all the wasted time. It is so very easy to see anything but the most minor radial and lateral runout while the tire spins on the balancer. If the tire/wheel combo is jumping all over the place on the balancer, the first thing to do is to see if it is mounted correctly on the balancers centering arbor. Even though the Tacoma wheel is lug centric, it does have a very snug center hole (with factory wheels) that fits tight on the machined area on the hub. Although not perfect, it should balance well enough to satisfy most people, and that is the way most people are riding around anyway,as very few places have/use the proper adapters. Just squatting down and watching the tire spin is enough in some cases to see that a wheel is not true, or a tire is bad. They might not have done it the first time, but after repeated visits you would think they would start looking for a cause. Get either 2 or 4 new tires and spin wheels without tires on either balancer or bolted to a back axle and look for runout, as bad as you say it is you should see some lateral runout, if not get a magnetic base dial indicator. You will need a dial indicator to see the radial runout unless it is excessive. I would still look for a bent axle shaft on rear, although swapping tires appears to have located the problem. I just can't believe you came back several times for same problem and all they did was to try a re-balance. (not you I don't believe, the techs).
The right front which passed with flying colors and didn't need much weight, was already on the left rear before last rotation and the problem was happening then. The "fail" is on the RR and it is smooth. It has to be something with the truck. I am calling my SA and see what all they inspected last time. I am wondering if a drum or maybe even the carrier bearing could be worn out since that is a cause of a vibration at a certain speed. I am also looking up how to contact Toyota Inc.
Thanks for being pissed off for me. I love this truck, but this junk ain't worth it.
Re: Bed Shake
Are you sure that tire is not uni-directional???
