Any ideas why a 2003 chevy trailblazer may vibrate in the front but stops when you turn left

Does the vehicle make any noises while driving? If there is a "growling or roaring " noise associated with the vibration, check the right front hub bearing. If there are no noises and only vibration, check the right front upper ball joint and control arm bushings. The Trailblazer's upper ball joint and control arm bushings become worn and cause the tire and wheel assembly to shimmy while driving. The vibration stops when turning left because of weight transfer to the right side which keeps the wheel steady for a moment. Also, check the tire for irregular wear.

I was wondering on a alero 99 , i replaced the brakes and a caliper and fixed my brake lines but my abs light is on but it sounds like a airplain when u drive their is no shaking or grinding in the front...

YEP BAD WHEEL BEARING WILL MAKE A ROARING LIKE NOISE WHILE IN MOTION.BAD WHEEL COULD PUT DRAG ON WHEEL WHICH CAUSE ABS LIGHT TO COME ON.YOUR WHEEL BEARING HAS THE WHEEL SPEED SENSOR BUILT INTO IT.SO IF WHEEL BEARING BAD THE WHEEL SPEED SENSOR PART OF ABS BRAKE SYSTEM WILL CAUSE ABS LIGHT TO COME ON IF WHEEL BEARING BAD.MAKE SURE FRONT BRAKE PADS INSTALLED CORRECTLY IF NOT. YOU WILL GET TERRIBLE WHEEL NOISE ALSO.

It has a growling or humming sound from 35 mph on up.

Have your front hub bearings check,These cars are known for front hub bearing going out.

Roaring noise in front of 2003 olds alero gets louder as I accelerate, sounds like manual transmission needing to be shifted to next gear(this isn't a manual transmission

Have a shop look at it. It may just be a failed wheel bearing. The bearing will leave you stranded if it gets bad enough and cause more damage.

My power steering pump makes a growling noise even when the car is idle. The noise is louder when I turn the steering wheel. The power steering fluid has gotten low a couple of times and gets foamy.

if gets low definitely a leak foam is pump mixing fluid with air roar is pump cavitation check lines or pump for leak keep fluid at recommended level air bound unit can cause steering difficulty and or failure if need have trained mech look into problem
