You can't cut the frame... somebody tell chevy that... I had a 2000 chevy that the left front coil spring was warped or out of whack somehow, and it rubbed against the frame and made a squeaking sound that drove me nuts. I had it in several times and they never fixed it (too cheap to order a spring that would fit right I guess). The last time, after I thoroughly chewed out the service manager, they just cut notches out of the frame rail where the spring was rubbing, so as to alleviate the problem! Naturally I was quite upset, so upset that I vowed to never get a chevy truck again and I told them I was going to trade it in on a Dodge. Well, I guess it had a happy ending after all!
