I recently replaced both front wheel bearing, drive shaft, radiator, heating core, all ball joints, idler arm and over a year ago replaced the engine due to 3 blown cylinders. So now my rear driver side tire squeaks while driving. At first it would cut in and out during a drive but now its constant. But today when I put on my brakes and heard grinding. Very similar to front wheel bearing sound but its not humming like the front did. So I'm cubit decide whether its my brakes or wheel bearing. I've done so much with this thing I don't want to do one thing and have it be the other. How to know the different signs of either or. Thank you so much.

Based on the type of noise, I'd start with a basic brake system inspection. Worn brake linings would just be a normal maintenance item, and to have to replace them can be expected at the mileage you listed. If you do need to replace anything, tell me whether you have disc or drum rear brakes.

Disc brakes from what I see for parts online but it's been known for people to replace with drum brakes.

Nope. You only replace with what you have. It depends on what the vehicle came with. It's not important now anyway until we get into procedures or diagnosis.
