My Manual Tranny or differential is making some horrible grinding noise. I cannot pinpoint the location, but I put the truck on for jack stand and started it up then this grinding noisy. I put the truck in neutral and the rear tires spin I back it out the garage and she makes the noisy again. I did check the fluid in both tranny amd differntial, its good.
Any possible answer to this problem. This just started yesterday on the way home from work.
