I added body mount insulator, GM part #15899719, between the bottom of the upper body mount and the frame like TSB says...PRAISE THE LORD!!!! The popping has stopped, going on three days and haven't heard or felt it.... now, if I can only locate the rattle behind the dash....aarrrgghhhhhh! ps, clean mating surfaces like TSB also states.....

This is the problem I am having....."popping-type noise coming from the front of the vehicle. This condition is most apparent during hard left or right turns at low speeds. Going over bumps while turning may also aid in producing this noise." I can feel it in the floor board and as far as I could tell it was the driver side only. after many more miles popping started getting worse(more frequent) but I was not able to feel it in the floorboard all the time anymore. just shy of 80,000 miles I replaced the lower ball joint, upper control arm/ball joint, and the outer tie rod end(all driver side).....the popping got better, seemed to go back to what it was about 40,000 miles earlier, just the single pop when making a slow sharp turn and the suspension is loaded or unloaded and the pop can be felt in the floor board. Since that didn't fix the problem I did some online searching and found the TSB to install the washers on the crossmemeber so I stopped by Chevy and picked up eight. When I replaced the driver side ball joints I was able to spin the ball joints with my fingers so I figured the passenger side ones were worn too so they would need replacement and I could do it when I try installing the hardened washers....well I scraped off the undercoating and installed the washers and I am not certain but I think it is also poping on the passenger side now, definetly DID NOT fix the driver side popping. I am going to try the body mount insulator TSB and see if that fixes it....if I find the issue, I will post my fix. Sidenote: IMHO, if the frame flexes and moves inside the crossmember untill the bolt makes contact, "popping" from one extent to the other, slotting the member is moronic...even if it did make the noise stop it will reduce stiffness...and I still cannot figure out how washers would help either?!?!?
