rubbing /grabbing sound from front end

100% sure noise is from the front? .. *Limited slip differential* clutches will surely make that same noise under those same conditions as the lubricant breaks down over time! ... I believe I'd have the lubricant changed and make sure it's refilled with the proper *limited slip* lubricant.... What other choices you got? > Vehicle presence IS required for hands-on testing + audible summation of noises present while driving! .. You may need to find a more experienced mechanic to do the testing.
