Poly sway bar bushings helped a lot on my 100k mile 4th gen. I am not sure how much of an improvement they would be over newer rubber bushings.

A 4Runner is a boat. You drive it as such on the interstate, with your inputs coming from the bottom of the steering wheel like a well heeled gentleman operating a fine nautical craft in-route to a sophisticated social engagement. Remember, you’re not in a rush. That’s for the poors.
If that ain’t your bag, save your nickels and get the Cayenne you quietly lust after so you can have lengthy conversation about how “communicative” the steering is and how well they treat you at the dealer.

Haha seriously. If you don't have the dreaded steering wheel wobble, count your blessings and enjoy the drive!
If I'm feeling in a sporty mood, I can hop into my wife's Hyundai Santa Fe 4 cylinder turbo, flick the steering wheel mode to Sport, and try to Tokyo Drift around the nearest roundabout.

Before this thread gets too ridiculous..
1. Larger rims with lower profile tires.
2. Heavy duty sway bars.
3. Poly bushings.
4. Performance shocks.
5. Front upper and lower control arms.
I think the most cost:benefit here would be lower profile tires and sway bars (assuming someone makes one). Sidewall flex may have a bit to do with what you’re feeling, or not feeling.

hyundai - what is exactly steering feedback? - Motor Vehicle Maintenance & Repair Stack Exchange
In auto parlance at the high end its called "Dynamic steering"
Dynamic steering varies the steering ratio by nearly 100 percent as a function of driving speed and the setting in the Audi drive select system in which it is integrated. Transitions are continuous and practically imperceptible.
This both makes the car feel more sporty at higher speeds and safer, while also making it easier to do things like parallel park or make a u-turn. Instead of trying to achieve the perfect balance of steering ratio and power steering assistance, these cars can vary it to give you the best of both worlds.
Hope that helps. Basically the 4Runner is poor at "steering feedback" and has no dynamic steering - this is what i want to improve as best I can for the near "perfect" vehicle

You can do a lot with a light duty car suspension that you can't with a vehicle that also has to be able to handle the type of abuse that a 4Runner is intended to. Everything on the 4Runner has to be much larger and heavier. The result is a relatively heavy feeling.
There are also geometry compromises that are inherent in off road vehicles. For example on most Audi models that use a design that locates the upper ball joint over top of the tire with a pivot axis that runs approximately through the center of the tire's tread. That means you can never put a larger tire on due to physical constraint. You can't do that on a vehicle where a large portion of customers are going to put larger tires on.
There are many more compromises for a big heavy SUV, but those are just a few examples.
My guess is that you'd probably solve most of your issue with a better alignment set to around 3.5-4* caster. For comparison example a typical sedan will often have a caster angle of around 7-8*.

Get a long travel suspension and you'll be fine.

You could always do what i did, it’s really smooth now.

Drive a lifted Jeep Wrangler with bigger tires on the freeway going 75-80 mph, that will improve your 4Rs handling perspective.
Which I had to do yesterday in my wife’s Jeep on highways with heavy construction. Mad Max hanging on for dear life in those conditions! Exhausting

Its FEEL of the road - as in literally, you can feel the pull of the road on your steering wheel. If you want to see what feel "feels" like, go drive an Audi, BMW X3, Porsche or Volkswagon. Now that said, I would never expect to get to that level in a 4runner. Lol just seek improvement here. Here is the example, albeit dangerous to help explain feel. And even this might not help someone might be able to explain it better.....
At 60 MPH on an open road close your eyes. (although i dont recommend this). How long can you keep your eyes closed before you feel unsafe, or you don't know where you are in spacial perception? In a 4runner, since there is no road feel, its practically immediate. In contrast, in my Audi I could, in theory, close my eyes for 4-5 seconds and know where my car is in space on the lane for that duration. (only an insane person would go longer haha - its just an example folks!)
Not trying to get into a debate about this, you either know what i am talking about or dont. (Or have no experience yet with driving vehicles with perfect feel of the road) Any old racers in here? :-)
excellent. I will investigate this option on if impacts on what i am looking for. again, its not alignment or play in the wheel.
And suspension upgrades makes sense, i would love to test drive a nice test up. Thanks ALL!!

we came from a bmw x5M and in no way could I get the 4 runner to ever drive remotely like that SUV. It drives more like a truck than an sport or crossover suv. That is actually part of the reason we got 1. When the road stops the 4 runner keeps going and the Audi and X5 can't. No matter what you do to your Audi or BMW it will not go where I take the 4 runner at times. There is a trade off going to a real SUV that behaves ok on the road yet is truly offroad capable

All you need is 4.0 caster to get the feel....beyond that it isn't going to become a Road Racer no matter what.

Add Bilstein 5100s and max out the caster - handling is no problem. On this delightful stretch of Hwy 129, most cars and Harleys end up pulling over to let this boat around. Of course, I pull over to let the sport cars and bikes get around. Once you get used to the roll, cornering limits, and occasional stability control interventions, you can still sling it around the curves.

I LOVE the 4Runner, but its my biggest complaint of the vehicle as it really could be a safety issue. If this could somehow be improved, I would invest a lot in order to do so.
My understand it the height is factor that causes this, (and of course the engineering in all the linkages) and it may be impossible to really improve it.
But I thought i would ask those who might be mechanically inclines and know the intricacies of this stuff.

Drive a Wrangler right before you drive the 4R.

Just don't buy one right before you buy your 4Runner. It becomes an expensive comparison. I will say the JL Wrangler handles the curves better due to less top heavy, much better acceleration, smarter transmission, etc. but it is a pain on the open road with the noise and SFA lack of precision.

I have a 2016 A6 Quattro Prestige with 27k miles on it and a 2017 4Runner Limited with the same and while the Audi clearly is a better handling car I don't feel the T4R is sloppy, just slow.
Might want to check tire pressure?
