OK I know I am new to the forum but any help would be great.

I have a 2001 Toyota Tundra, I have noticed a spueak when backing up but not sure what it could be. Then today i was backing up and a grinding sound started and when i drove back into my garage it took a little more gas to make the truck move forward well turning but seemed to move normal if the front wheels are straight.

Anyway i have no idea what it good be i have heard maybe a U-joint, but this is my first truck and i am not very good at this kind of thing....

any idea or if u have questions that would help u figure out whats wrong i'll do my best to explain it better...

Thanks for any help
