Front end "shimmy"

[nitrox264]

Hello everyone newbie here
Just left the dealership and had the tires rotated and balanced on my
1999 4runner 2wd limited 145k miles and still have a shimmy at speeds over 55. The tires are newer, new rotors, new brakes (I have done). I am the second owner. Everything else in the front end could be in question on how old. Is there anything I can do that may improve this situation. I'm pretty good with mechanics and would like to fix this.
Any help would be greatly appreciated. Thank you

Yeah, get a balancer at Harbor Freight and do it yourself. Then make sure the front wheels are on straight and centered and the bolts tightened evenly so the wheel is centered properly on the hub.

it is a balance issue, ask your dealer if they have service bulliten tsb 002-96. It calles for a hawkea adapter to be used on all toyota wheels. It made a huge differance for me.

I swear this fixed my steering wheel shimmy, it is real nice to be rid of it! The road force balance is nice but not necessary if the adapter is used. My local discount tire called it a finger plate adapter. check these links

Thank you all for the info. I will get it done again.

So the special adapter is for the balancing machine, not the vehicle? That would explain why a lot of people haven't been able to get their wheels balanced properly I guess. It would probably be a lot easier to do it yourself than to get the shop to buy the correct adapters though.
