I, and many others, will be really interested to see how it goes, and the ride afterwards (if in fact new springs get installed..). Thanks for helpful insight.This is a great write up! I initially tried the dealership where I bought my GX, they wanted nothing to do with even trying to help out. Called another dealer down the road and they came back with the exact same info you posted. They even said I already had the rear coil in mine, but also agreed that it didn’t make sense, but they are still looking into it and are going to try and reach out at the end of the week. Please keep us informed on your guys progress, thanks!
