I wimped out guys (see bushing replacement post under Monaco forum). Took the coach to a commercial truck shop and had the upper torque arm bushings replaced. Then took it to a truck tire shop to have the inside tires replaced after the first shop inadvertently inserted the arm retaining bolts incorrectly and cut a huge groove in the tires. Close call but no blow-out. These Michelin tires have a LOT of rubber in the sidewalls!
I watched the tire guy work. One young fellow in his mid-20's and about 165 pounds did it all himself. The HUGE air-impact wrench was the clincher though. It made short work of the wheel nuts. Convinced myself to keep the road service contract current cause this is a job beyond my capabilities. Now maybe if I weighed more than the wheels (you a biggun there wa8yxm) I might give it a try.
