Hey All! I'm back. Never did sell the Trailblazer. Couldn't let go of it. I'm back on the road with it.
The issue: there is an intermittent metallic-ish squeaking consistent with wheel speed that tends to occur at lower speeds, though I think I have heard it whining intermittently at 35-miles-ish an hour. It is most noticeable at take-off and coming to a stop. It sounds about the same at take-off and stopping, and it doesn't change whether the brake pedal is depressed or not. If I go from stop and hit the throttle hard, it seems to go away under acceleration but return again when I am off the throttle, and this is true even if I am just spinning the back wheels in the snow. It sounds like it is coming from up front, sort of center-ish, maybe.
The truck has been mostly sitting for the last almost four years, due to transmission issues which are (mostly?) fixed (still a little leak, still have to figure that out). I pulled the transmission down, had it rebuilt, and put it back up.
I almost wonder if it is the front propeller shaft, though that doesn't make a ton of sense. Could be a brake issue. Dude at the oil change today guessed hub, but his guess is as good as anyone else's.
Any thoughts on how to narrow down the toubleshooting?
