Question Weird grinding front right 04 sti

Hey guys I have a 2004 STI with 135,000 miles on the clock. Having a weird issue that I am having a hard time figuring out.

During anywhere from 25mph-65mph left hand turns I have a loud grinding noise from the front right wheel area.

Things I have found out:
1. Noise only present on left hand turns that are either slight to moderate uphill, downhill left turns.
2. Bumpy roads do not affect it
3. Sound does not change with RPM
4. Doesn't matter what gear
5. Doesn't matter if I brake or accelerate through corner

Things I have tried to fix or diagnose
1. Replaced wheel bearing
2. Checked rotors for rubbing
3. Still a lot of brake pad left
4. Checked fenders for rubbing
5. Checked sway bar and end link bushing

Mods
downpipe, up pipe, skidplate, feal coiloivers (13.75f/14r), cobb swaybars, stock wheels and tires, and group n engine mounts, pitch stop, sexy rear end.

Before noise
Car was in shop getting 135k service. Brake fluid flush, tranny fluid, oil change, rear diff fluid, etc etc. Also had left front axle boots replaced due to a small tear.

Drove the car home and couple days later ebrake light came on and I noticed brake fluid on left side of my car, found bleeder not tightened all the way. Took it back to shop and they fixed it, refilled my fluid, and cleaned my car.

Week later the grinding noise started. Took it back to shop and they drove it around put it up on the rack and checked everything. They concluded it was the wheel bearing. They replaced wheel bearing and grinding noise is still present.


Thoughts? Ideas?

Did you check inside and outside brake pad? If your caliper or guide pins are frozen one pad can wear significantly faster than the other.

I would check all 4 brakes and bearings. Sounds can sound like they are coming from one place and actually be coming from another.

Be sure to check inside of rotors to see if brakes are grinding away at the metal..

Take it to another shop, preferably a Subaru dealership, to get a second opinion. Depending on what they diagnose I would go back to the original shop and have a strong word with the manager. If they misdiagnosed something fight your case to have it covered by them.
