Our bus had a broken shock and it pulled to the right a little. There are two shocks on each side, 4 total for the steer axle. When a mechanic told me he was ordering me a new shock for the right tag where the top post had been snapped off I told him to get 1 more for the front, and install. I get a call back, now both shocks on the right front are broke and he believes its because of worn out bushings. I dont doubt this, 215000miles, it does pull that way and shocks are broken. Excuse me Jon if I misname the parts but for lack of a better term TORQUE ARMS. There are 5 of them up front, a bushing on each end. Cost of the bushings 6bucks each, labor, mabye 2 hours each arm? Anybody ever did this job? How hard can it be? Is this something that is normally at the end of its lifespan at 2000000 miles? These arent something that are greased. There kinda like the equal to control arm bushings on a car. I can imagine what the back axle is like, probably pretty much the same.
