So I took the wagon to get an estimate on replacing the rear bushings. The guy said, $255, plus $25 to the machine shop. I supply the bushings. I thought, sounds resonable. When he put it on the lift to take a look, he pointed out that the bushings, the big ones, had been tack welded in...and they were. A common practice with cab owners as a quick fix to keep to keep things from bouncing around until they could afford to do the job, he said...This being New York City. Then he suggested, I get an extra pair of trailing arms just in case the mine were damaged while removing the bushings. So I located a pair that would cost me another $100 bucks...just in case? So my question is, has anyone dealt with this problem of welded bushings? Is it a big problem to grind off the tacks? This extra $100, makes me feel like maybe I should try doing this myself with a grinder and one of those home-made pusher tools.
