A few months ago a high pitched squeal started coming from the rear of my car. At the beginning when the problem started, the squeal would only occur over 25-30mph for about 10 seconds or so. It got worse over the few months to the point where it would squeal for the whole ride (still only above 25mph).

I took it to the shop recently and they changed the throw bearing and clutch, which did make the problem better but did not completely fix it. It’s basically back to the point where it only squeals for about 10 seconds. Any ideas what the problem might be? I tested it and the noise still occurs above 25mph even with the car out of gear and the engine off.
