I came across this thread:Toyota 4Runner Questions - What will cause a steering wheel shimmy at 60-65mph other than tires, ... - CarGurus talking about how the 5th gen 4runner needs a Haweka adapter to balance the tires correctly, otherwise it can wobble. I am definitely experiencing wobble so I'm curious if anyone else has heard of this? I think I may call around and try and find someone who says they have it.

"Here is the problem. The wheels used on the 4Runner/Tacoma are “lug centric” and are not the more common “hub centric” wheels like on most cars and light trucks. Hub centric wheels are centered on the vehicle hubs using the center hole in the wheel. That is kind of simple. On lug centric wheels the wheels are centered on the vehicle hub using the lug bolt holes and not the center hole. When the wheels are made and machined they are done so using the lug holes to mount the wheels to the machines that make them. The lug holes are the true center of the wheel and not the center hole. So, if the center hole is not in the true center you can understand how mounting the wheel to the balance machine using the center hole is not going to work very well. The wheel needs to be mounted to the balance machine using the lugholes. This is done with a flange plate adapter made by Haweka.

If you have something that is just slightly out of whack you will definitely know it on these trucks. If you have a vibration and believe it to be cause be the wheels and/or tires, then you should not waste your time by going to a shop with old technology. If your time is as valuable as mine then you should find a shop with the needed Haweka adapter, a GSP-9700, and a technician that has a clue. The easiest way to find what you need is to go this web site and use their shop locator function to get a list of shops near you that has one. Next call the shops and make sure that they have the Haweka adaptor for your wheels. If they tell you that they do not have it or don’t need it, then hang up and call the next shop. Do not waste your time with them. If they are willing to spend $10,000 on the state of the art road force balancer, and not get a set of Haweka adapters to go with it then they probably are not smart enough to work the machine anyway. When you find a shop that has both items make an appointment and have them do a road force variation work up and see if you need to replace your wheels or tires and then get a good old-fashioned balance. The combination of the GSP-9700 and the Haweka adaptor should cure the most common cause of vibration in the 4Runners and Tacomas. This combination will give you the greatest chance of getting you vibration problem fixed on the first visit as possible."

Wrong. 5th gen wheels are hubcentric. If they were lugcentric owner’s manual would not recomend to torque lugs while “vehicle is lowered to the ground”. Factory wheels center on the hub once tighened to proper torque.

Yes, you really need the Haweka adapter NOT because the Toyota wheels are lug centric...they are hub centric (there is a 'lip' on the hubs that the wheel 'sits' on), but because Toyota wheels have an unusually larger center bore. The standard way of mounting and centering the wheel/tire onto the balancing machine does not work well with Toyota wheels...hence the need for the adapter.

Save yourself some trouble and avoid Les Schwab if you're trying to use the Haweka adapter. They told me they knew exactly how to use it and then took a chunk out of two of my wheels. They then admitted they'd never actually used the adapter. This was after I called 4 stores to find one who could.

Around where I live, the only place that seems to have let alone know how to use the adapter was the local Toyota dealership...they even had road force balancing available which is rare in this area. One place I didn't check was the specialty shops (racing, 4x4, etc.)
