If anything like the Mack Dump truck I pulled offline years ago you probably a bad place in the roadway that jarred that bushing. I pulled the Mack after the shop foreman okayed it to return to work as the driver return within two hours saying it wasn't fixed. I pull it into the oil change bay and did a DOT inspection of the front end. Boy was it bad both lower balljoint nearly fell apart as I raised the axles; not mentioning the rest of the problems I found in the front suspension, The driver asked when he was getting the truck back. I just said just go get another truck assigned and this would be offline for several days.
