ha...drive out to hempstead. I'll show you a wobbly rear. With my control arm as is....yeah.
In your siruation, my fist guess is the tire is bad. If you have a road hazzard, use it to get a new one or that one repaired. If not...check it over very well. Other things would be bad alignment or loose wheel. Alignment is my issue. Also, with the steets here, your RSMs could be gone, but unrelated to the problem at hand.
