Vibration going 60+ only turning right Options

[MSKapcala]

I am hoping to get some ideas for what could be causing this, but first a little backstory.

I took my 1997 GT convertible to my mechanic to have some stuff replaced and to check the driver side rear wheel bearing, because when I turned right going 40mph or more I would hear and feel (a little) a vibration-type sound and it felt like it was coming from the rear. It would happen only when turning right, when the weight of the vehicle was shifting left and I was at 40mph or higher.

So my mechanic replaced the rear-wheel bearing and since I have had it back, it seemed fixed. Then this morning, I was going around 60mph turning right around a curve and I heard the noise again, but not quite as pronounced. But again, it's only when turning right and the weight of the vehicle shifts to the left, going 60ish or so now.

Any ideas on what this could be? The front left wheel bearing? Or should I recommend they look at the bushings in the suspension/steering? Originally, they said they couldn't really re-produce the noise, but then eventually came to the conclusion it was the left rear wheel bearing. I drive the vehicle every week, so I know how to "produce it", so to speak.

Any help would be great, I just don't want to be driving and something break and I have a big problem or accident. Thanks!

If you're not sure if the noise is coming from the rear or front, it could be the other wheel bearing? What brand wheel bearing did you have them install? There's a chance that the one they installed COULD be faulty (I've seen it happen before). How long was it from install to the time you started to hear it again? Did it totally go away once the wheel bearing was replaced?

I had a 2004 Corolla that went through about 5 wheel bearings on the front left corner. Torque spec on the nut was spot on, everything was being done by the book. Turned out that there was obviously a bad ground to the body, so I installed a new ground from the battery to the fender inside the engine bay. What can happen is a current during cranking will run through the suspension and through the wheel bearing, arcing across the bearings, causing pitting and ruining them prematurely. It sounds super far fetched, but actually not as uncommon as you'd might think. Check your grounds just to be safe.

My bet is it's either a different bearing or the one you installed was DOA.
