I put some Autozone U-joints in my truck this spring....bad move. I think one is starting to clunk already. The one i usually go to has terrible customer service.....i stood there for 20 minutes once trying to get waited on. But, their parts are cheap, and they will match Summit's or Jeg's price for performance parts. For the most part, i have had excellent luck with O'Reilly's. All the guys there are knowledgeable, and i usually don't have to wait forever to talk to someone. They also give me all the free nuts and bolts i could ask for (as long as they aren't grade 8). I guess it takes them longer to ring up then the fasteners are worth, so they just give them to me for free
Autozone calipers are looking better and better....and for $13 you can't complain
