Well hell! It seems as if there is something else wrong with my truck that needs immediate attention! I'm hoping that I just need to put some more gear oil in it but it makes this clicking, rachet-like sound whenever I take my foot off of the gas. This really sucks because I know I don't have a limited slip in there and I just had the tranny rebuilt, so it's probably not that. It also makes this low groaning sound when I apply the brakes firmly. I hope that any of you guys can help me out with this one. I'm very stressed out about it. Thanks in advance, Buddy I've got my dream truck and it's a 72 K-5 that is getting there!!
