Ok so i know this is the rex forum but my truck has a problem.

It started last week when I was going about 55mph and I had to let off the gas quick , didnt even touch breaks, it sounded like my axle or something was spinning. It wasnt a grinding sound like it would be for breaks. It sounded like something was loose and was spinning whether its an axle or rotar, i dunno. Just seeing if you guys have any opinions before I tear it apart completely or take it to a shop.

Its an automatic if that helps.
