welcome to the club lol.

Mine had been doing that for years. Only when I stop and then when i take off again. It wont do it while moving till I stop and go again. Sometimes it goes for months at a time then comes back for a week or so.

Suspension is fine, and axles are fine.

I should really check things out now that the engine is out thoough, lets get this figured out.

Oh btw, mine is ouder on the passenger side.
