Steering shake during highway driving

Been experiencing minor steering when driving above 65mph. When applying brake also seeing steering shaking as well.
Took to Toyota dealer they wanted charging me $600 for rotors replacement, any thoughts?

 

Do the rotors yourself

 

First have your tires checked and make sure they are properly balanced.
Also is your truck still under warranty?
Also new rotors needing new a 3 year old truck? That seems unusual. How many miles on the truck?

 

Before spending $$$ on rotors, I'd opt for road-force balancing of all 4 wheels.
Static balancing doesn't always result in perfectly balanced wheels + tires.

 

Are they expensive? I heard it’s like $300 service

 

I had a braking vibration when braking from 55 mph to 35 mph around 40K miles on my factory brakes. Normally I like to stay with OEM but put PowerStop pads and rotors on and the vibration went away.

I don't recall what my dealer charged for it as it was a few years ago with my previous Taco.
I had bought 4 tires for my '06 thru a local shop. They mounted and balanced all 4. Experienced some minor vibration and a bit of minor side-to-side action in the steering wheel. After a few days of driving with this I took my truck to my local Toyota dealer and had them road-force balance all 4 wheels. Problem solved.
