the internal shroud on my flywheel is cracked and rubbing. How hard is it to fix and roughly how much?

Just replaced the radiator and the heater is now not working; it just blows cold air. I fixed my overheating problem now I have not heat....! Is this heater core problem or maybe something went wrong when I replaced the radiator??

My car make noise ( sort of a grinding, growling) sound when I turn to the right also to the left but not so pronounced. Going forward, it seems to be OK. Whats wrong and how much to fix. Car runs well otherwise

Frequent/extreme engine pinging during acceleration; recent cross-country trip suggests rich fuel/air mixture because the pinging went away at higher altitudes (pinging gone above 6000 feet). Should I just replace the O2 sensor? Or could it also be the injectors or ECM?

For some reason when I push the 4WD button on shifter, it doesn't engage the 4WD. Any suggestions as to what he culprit could be?

I recently replaced the bearings, front brake rotors, master cylinder, calipers, brackets (including new pins and bushings) and pads. I bench-bled the master cylinder and bled the system following the recommended pattern (RR,LF,LR,RF). Now the brake pedal does not feel "spongy", but it does feel "springy". For example, if I pull up on the parking brake lever hard (keeping the button pushed in with my thumb), then when I press the brake pedal I can feel some "give" in the parking brake, and if I watch i can see mechanical movement of the caliper as I press the pedal. It's been too long since I've driven the car and I can't recall if this is normal or not. It does not feel like it's braking "confidently". Feels like too much pedal travel needed, but pumping does not change anything (seems not likely to be air in the lines). Any other suggestions what might be causing this?
