Ok guys when i am driving in high gear going slow or just cruising 5th or 4th i hear a horrible noise that sounds like scraping rocks. Now this is when i am going a constant speed and then i accelerate. you can hear it in all gears but it is louder and more noticable in a coasting gear. universal joints are new. I am sort of lost with it. may be the tailshaft bushing not sure but i need help please. thanks also it is a WC T5 and i have an aluminum drive shaft with 373 gears if that helps any.
