So a little update on this issue.. I took a look at all suspension components and checked all bolts and nuts and nothing was loose or showed any signs of protentional issues. I had to take the truck in for a few other warranty items, so i added the noise to the list of things they needed to check. The next day i got a call back from the dealer stating that they wouldn't and couldn't touch the suspension since it had been lifted and that was not covered, BUT that they did find some loose parts. So told them don't touch it, ill take it back to where i got it done to take a look. ( i did the install back in 2018 when i got the truck ) so not sure what they found or were talking about because before taking it to them, i had checked all suspension parts and made sure everything was torqued to spec. Once i picked up the truck i noticed that the noise was no longer there and hasn't happened since that day and its been few months now.. could they have actually found something and torqued it down and not charged me for the work or even acknowledged they touched it?
Few weeks ago i had my door lock stop working on the back door and battery issues, so this time i took it to another mechanic(not a dealership) and asked that while they had it, to check it out again just to see if they found anything because that one front tire was wearing out on the outside of the tire. The had the truck for a few days and was told that they didn't find anything either, had the alignment checked and said that the alignment camber was barely out of spec, but couldn't for sure say if that caused the wearing on the tire since it was so minor, but as for the popping, they couldn't find any issues with the suspension. So I'm at a loss on what the pop was and why its not there after the dealership, which states they didn't touch anything.
