I own a 2004 Tacoma PreRunner V6 w/ TRD package. I am experincing a bed shake at speeds between 50-60mph. It pretty much starts right when I hit 50mph. It is on the LR because I can watch the shake in my mirror and I feel it in my seat and not the stearing wheel. I have had my tires rotated and balanced and I am even using the spare (BF GoodRich Rugged Trail). I had the spare balanced, and so far, the problem still persists. I have Runway Enduro HTs on the tire which came with the truck when I bought it used back in 2006. I am starting to wonder if anything is wrong with the suspension. I am not sure what much can go wrong with a solid axle and leaf springs. Has anyone had this same problem? Any solutions? Any thoughts? I am calling my service advisor again and telling him to find the problem. I am attaching a picture of my truck. Oh and yes, the dirt bike is for sale.
well you need to have them check out your truck just like yesterday with my
2006 tundra DC they trade to cut off the light on my truck that tell me when the tire has low air in it and they did not what to put it on the lift so he took my truck up to one
of the shop doors the guy at the computer. and told me tech the guy will check the air in
my tire so he check and the four were fine so he back up the truck to check the spare
it was fine but then I turned and looked to see a nail in my rear tire now if I would have
went home I could possible get a flat on my two day buissness trip Mon and tues day
so the point is if you konw somthing is wrong stick to your guns and have them check it out and don't leave untill you do the guy in told me that it would be a long wait but
I did not care and I got my tire fixed I bought tire care package for my truck from toyota
and if there is a issue with the tires they will fix it so good luck and rember stick to what you belive.
Yeah, they had it all day Saturday and told me the tires weren't balanced (they balanced them two months ago). This has been going on for a while and it did not solve the issue. It is still occuring. I think there is something wrong with the rear suspension. I am calling again to a) ask what they did and b) why didn't they fix the leaf spring that I found slightly off center (which might be causing it). More to come.
I would be all over them about the issuesthat you are having with your truck
not to melntion you are making payments on this truck there should not be no issues.
Yeah, I went to call my service advisor's back up while he is on vacation, and he too is off today. I am calling him first thing Tuesday morning and finding out what they did and that they need to find it. This is a 2004, not a 1994. I might try another dealer if they don't resolve it. If no luck in the end, adios Taco. This is really frustrating.
I just spoke to my service advisor after having my truck all day. They inspected the rear suspension for any issues including the "kicked out" helper leaf spring. Both the senior and manager in the service department said that issue wouldn't cause it. That is not an issue. They checked the tires again and after balancing them on Saturday, they were slightly out again. They balanced them again. They are saying that it is the tire (possible tread separation, aggressive tread [which is HT - in my mind, not aggressive, etc]). I can calll and try to speak to the service man if I call tonight before 6pm. I need to know how many tires needed rebalanced because they have been moved before all of this and it still occured (previous rotations). I am really wondering if that is the cause because before having them look into this, my spare, which was a factory BF Goodrich Rugged Trail, was put on the left rear and it too did this. I have heard bad things about this tire, but come on, more then one tire and the spare too? I am not sure what I am going to do with this truck. I can't afford to put new tires on it; especially if the problem persists.
I'd still think it has to be the wheel/tire not being balanced right, or they are just out of round and no matter how much you balance it, it won't make it work right. I don't think the bearings in the axle would be shot, but it's possible.

I just spoke to the service advisor and he said that the front 2 tires were okay after Saturday's balancing. He did state that it is quite possible that the spare could be "not perfect" either. After 2 days (all day) of inspecting the suspension and under neath the truck, I think I am a believer too that the tires are the issue. I think they would have found something in 2 whole days of inspecting. He said the tech and service manager stated that the leaf spring kicked out a little would not cause the axle and drive shaft to get out of alignment. It is just annoying. The tires are Runway Enduro HT tires and are made for Tires Plus by Bridgestone. Maybe junk tires. I want to try to find who uses that "special" balancer that works for Toyotas.
Did they check to see if the rear axle is running true?, the PO could have slid it into a curb and bent it and/or the wheel. Do the wheels run true when the truck is on rack and allowed to spin 20-25MPH?. Steel or alloy wheels? Proper adapters used during balancing? Are the tires cupped/worn excessively? Some tires that have lots of miles running out of balance and have uneven wear are almost impossible to correctly balance again. Is this truck still under the original warranty? I would think the next steps are to check the driveshaft(s) to see if PO could have high centered the truck and bent one, and check the axle flange runout.
The reason the dealer did not fix the overload leaf is because they will prob scedule it for a later date, as that was not the reason you were there.
I wonder if this would solve it. I know Sun Toyota uses the Hunter machine, but if I can find someone to help with the other item that favors lug centric rims, then I am calling them.
It's most likely the tires then. A few 05-06 Tundra owners have complained of vibrations even after their tires were balanced and aligned several times. Switching to better tires cured the problem.

My truck is only 2WD so there is only one drive shaft. They checked everything and I even told them to fix the overload spring if it was causing the issue. My truck is out of factory warranty, but I have an extended warranty. After a few balances, I can see differences in when the vibration or bed shakes. They have looked it over twice and if something comes up later when I eventuall buy new tires, they will hear from me.
A contact that I spoke to says that Tacomas are not lug centric. The webiste I posted says otherwise to a point. Does anyone know for sure? He works for a tire manufacturer.
The Tacoma is lug centric. You can tell they are by the conical design of the factory lug nuts. When they are tightened town, they align the wheel perfectly on the hub.

Great, thanks. I thought is what lug centric meant. I experienced that last week when putting the spare on. I am going to try to find someone locally who uses the Hawekea Adapter. He said the maching by Hunter and attachments are far better then the Hawekea Adapter. However, he is also the one that said that Tacos are not lug centric. The Taco may not be, but the rims surely are. Maybe that is what he was trying to get at. I am not sure, but it is becoming a pain.
To my knowledge, there aren't too many hub centric applications out there, but it should be vehicle specific, not wheel specific, whether it be factory or aftermarket.
