Ok here is my story on that I did the same thing had the wife drive it in and out of the drive way Ka Klunk. Took it to the dealer after they replaced both axles and diff lol. It turned out to be the rear leaf springs needed grease. So now my driveway has grease spots all over it from greasing these things. But the Klunk now seems more front end I think it’s the shocks but I don’t wanna throw any parts at it until I’m certain. You read all over mixed things on the ranchos I don’t mind them myself but idk what the Klunk is. Sent from my iPhone using Tapatalk
