Ive got a 2021 4Runner, that is shaking at 60 + MPH.

40,000 miles, K2 tires. Tires have been rotated 3 times.

Ive read that it is a common issue with 4Runners, and a "road force" balance is often a cure.

"a road force tire balancer uses a load-roller to simulate the force of the road and gather data on the combined uniformity of a wheel and tire package"

Anybody dealt with this on a 4Runner ?

So far I have called Firestone tires, NTB, and Chabills and none do the road force balancing.

Anyplace in BR that does this ?

there's a shimmy, sometimes referred to as a "death wobble" by Jeep nerds, also common in F-250s that's associated with the suspension, drag link, steering damper, tie rods, maybe ball joints, just had the wife's Jeep in for that, done in a day for about a grand

I have a Tundra. Don’t know what a road force alignment is. But I do know you need a competent front e nd man to do a Toyota. They have eight adjustments on one wheel.

Your stabilizer bar can cause shimmy as unevenly worn brake rotors can. I changed the rubbers on my stabilizer and cured a shake one time.

I believe Discount tire has the hunter machine for road force balancing.

I used to have a class c RV that had to get the front wheels balanced like that.

The entire rotating assembly (hub, brake disc, half shafts, etc) is included in the balancing when spinning the whole assembly.

Most large truck shops and RV service shops do it this way also.

Try AGCO on Coursey Blvd. Think they do Road Force balancing.

More than likely the shop you took it to didn't have the adaptor for Toyotas to properly perform a balance, may not have even known that it existed. Have had two Tacomas and one 4Runner, seen it a couple of times. Take it somplace else.

I thought Discount Tire on Airline did this. I’m curious myself as I have an ‘18 4Runner that’s very noisy with a little wobble, although I put it down to not rotating the tires when I should. I have Nitto Terra Grapplers on mine.

Toyota 4x4s have more adjustments than other 4x4s. Need a shop that is familar with Tacoma/4runner front ends.
I have a tacoma and am looking at getting a Lexus GX/Toyota Fortuner first gen to make an overlanding vehicle.

Tires on a truck need to rotated more than every 13000 miles. A lot more. I'd bet dollars to doughnuts that you have cupped tires that need replaced.

Go to Tri-Care or Simple Simon. They have the Hunter (which is by far the best). Firestone also has it, but don’t go there.

Tri-Care charged me $125 for 5 tires.

Had an 04 Grand Cherokee with the worst death wobble you've ever seen. Trying to find a video I uploaded back in the day.

It would start shaking so bad that the wheels would bounce.

Not sure how many straight axle vehicles are still being produced. I know some super duty Ford trucks, Wranglers, and maybe RAM

I had a 2001 expedition that always had a vibration at highway speeds. Didn't matter if new bushings or tires. Always at a level of slightly annoying in the steering wheel. Didn't eat tires so I didn't worry too much about it.

I’ve spent nearly 300k miles in the same Toyota, it’s always pulled right and had some vibration. But I’ll take it over the alternatives.

I have never done it in a truck but I've used "Dyna Beads/Balance Beads" in motorcycle tires for years and have no complaints.

Once I was riding near an 18 wheeler and a tire blew out and I was hit by hundreds of little beads so I know they're used commercially. Again, I can't vouch for truck tires but it might be worth gambling $50 before thousands.

Here's a link from a Tundra forum. https://tundraheadquarters.com/bead-balancing-tires/

Same thing happened to my 2019 4Runner so I had my mechanic do a total suspension delete and I haven't had the issue since.

I've never rode in a 4Runner that didn't ride like a go kart over railroad ties

Use this site and locate a shop that uses this Hunter road force balancing machine. If they know how to use it properly, it will solve your issues.

You said "K2" tires.

Are these BF Goodrich K02 tires? If so, this is a pretty common problem with those tires. They can be hard to balance right out of the factory or after some wear.
