so my silveraydo zr2 now has around 1800 miles on the odo. i noticed a considerable thump in the rear end around a thousand miles ago, give or take, typically when driving over light bumps and turning one way or the other (rougher terrain makes the thumping even worse). FYI, that's when i noticed it, not necessarily when it started. i've done some googling and reading and it appears that it's likely "worn or defective leaf springs". not saying that's it, but that's what appears to be the likely culprit. i finally called the dealership this morning and setup an appointment. the service lady told me, "yeah, leaf springs are a common issue with these trucks, we'll get it in, check it out, and get it repaired." great, that makes me happy, going to get the issue resolved. no problem whatsover with that.
what i do have an issue with is that while researching this issue, it appears this has been an ongoing issue for several years, i.e. 3 or more. what in the hell is GM's problem when it comes to determining there's an issue (leaf springs, engine bearings, lifters, etc.) yet they continue to put the same garbage crap parts on new inventory knowing they'll be getting them back for warranty repair at a later date?? is it cost effective to the point they'd rather put the junk parts on vehicles to get the defective parts used up and out of inventory knowing they're getting whatever percentage back in for repair/replacement??
