Car shakes at high speeds even with good tires and alignment
High-speed vehicle vibration that persists despite balanced tires and proper alignment is often caused by warped brake rotors, which create a pulsing sensation felt in the seat rather than the steering wheel. This leaves drivers guessing whether the issue stems from rear brakes or other mechanical components like the drivetrain. Without identifying the true root cause, DIYers risk wasting time and money replacing parts prematurely.

“Noticed recently when applying the brakes, especially at higher speeds, there is significant pulsating/throbbing, and I sound like an 18 wheeler braking.”source ↗
“I don't feel anything in the steering wheel, but in the seat, so I'm assuming it's coming from the rear?”source ↗
“Was going to just replace the rear pads and rotors, assuming warped rotors, but I'm a newbie that may be jumping to conclusions.”source ↗
“So I’ve pretty much just noticed this noise this past week nd I honestly wouldn’t know when it started.”source ↗
“this sometimes get super freaking loud and I can’t tell what if this is just a loose part causing all this noise or if it’s gotta do with the motor??”source ↗
“Took my 2008 Subaru Impreza to the mechanic for power steering pump (old one died presumably from this shaking), he replaced the pump and said a bad rear wheeI bearing was causing the shaking so he replaced it, but he didn’t tighten the axle nut at all, to the point I could feel the whole assembly shift when I was driving.”source ↗
“I have a somewhat constant vibration above 60mph constant whether accelerating or decelerating.”source ↗
“If I let go of the steering wheels I can see it physically vibrate a little bit and the vibration doesn't change if I accelerate or let off, even pushing in the clutch.”source ↗
“Car shakes bad at highway speeds! Had hubs replaced, tires balanced, alignment, inner and outer tie rods, tires rotated. Please help”source ↗
“The tires are 6 years old. Did brakes a few weeks ago. Shaking has been happening for months”source ↗
“Check those tires, one time I had a bad vibration like that and it was one of the tires”source ↗
“Car shakes when driving at higher speeds. Thoughts on what could be root cause? Tire shop said tires are good and don’t need replacing or alignment.”source ↗
“After about 80 thousand km the disks look like this and the brakes would shudder after about 5 seconds during high speed braking.”source ↗

“vibrates/shakes at 70+ mph mainly through the body, even in neutral. I really only care about the highway vibrations since it feels like it's falling apart.”source ↗
“It's gone to two tire shops and a mechanic and they don't think it's bad but it feels really violent to me.”source ↗
