This is weird. I put my D60 together a few months ago without touching the king pins and running 38" bias plies. There was a major death wobble and couldn't be driven. Put a king pin rebuild kit in and only had a little wobble when the road curved right. This was good enough and not worth worrying about. Today I was getting ready for a trail run and lost about 40 pounds off my front bumper.Turned it from a winch bumper to just a winch tray. I headed out to gas up and as soon as I hit pavement and death wobble at about 10MPH. I drove it around for a bit and it'll be OK to get to the trail tomorrow but I would never expect a little weight to make that much difference. Anybody welse ever have a weight loss death wobble experience?
