The grinding from the rear could be your differential. Drain it and put new fluid in it (Limited Slip requires 75W-140 with friction modifier, if you have an LS rear end)

thats your rear end differential, i had the same problem and i drained my oil and refilled it and it was still grinding, so then i got a new rear end...

How do you tell if you have an LS rear end?

Also, I was looking at the Mobile 1 75W~140 and it says LS on the bottle. Does that have anything to do with anything?

Was going to do my rear end this weekend.

Look at the axle code on your drivers door sill.

It could be one of your back wheel bearings. Jack up the rear end and if the wheel is loose then its the wheel bearing. If thats whats wrong with it and you continue driving you will ruin your axle. I would hear mine grind when i was going around curves when it went out.
