This has happened to me before. It only happened once and it was shortly after I had installed my first lift kit, had the 35s on, and I was transitioning on a highway junction. I think the ESP even kicked on.

I pulled off the highway and into a parking lot, got out, and starting inspecting everything. I was sure if I had blown a shock or a coil came unseated or what the hell happened.

I never found anything out of place and it had never done it again. I did check all the torque on all suspension parts when I got home but everything was nice and tight.

I have heard where the stock steering stabilizer can last a really long time and is enough to run at least 35s.
