Need to resurrect this topic. Recently purchased a new 2018 Silverado 1500. Had a 4 inch BDS Suspension lift installed. Hadn't driven in 4wd auto until after the lift installed (less than 3k miles on the truck).. First snow put It in 4wd auto and experienced the noticeable sound and slight vibration (similar to riding over a rumble strip while accelerating 40-50 MPH), sounds/feels like coming from front transfer case felt in drivers floor board. No issues in 2wd. I am NOT mechanically inclined so can't think of a better explanation. I will take to the dealer but I suspect the first response will be lift caused It... Does anyone have any ideas of what causes.

Thanks, I agree regarding lift sizes. I like what other are doing to their rigs, but I think that more than 4" would have been too much for my taste. I wanted to just "beef" up the factory look, I am really happy with how It turned out. In my opinion they should come from the factory closer to this (factory before pic)....

Hi all, new here. First post. Love seeing all of your nice rides. Just finished '18 LT Z71 installed 4" BDS with Fox shocks, factory GMC Denali 20s and 295 60r20 Nitto Ridge Grapplers and AMP research powersteps I needed a 1/4 spacer in front to accommodate factory backspace, no rear spacers, very minimal trimming of front valance
