After about 500 miles (and too many years) I changed the break in engine oil. There was some metallic grit on the drain plug magnet but none on the oil filter medium. Compression in all cylinders was 160 +/- 2 psi.
WIth the coach front end jacked up and the wheels off for mechanical inspection I decided to lube the front end. On the driver side lower ball joint it was necessary to firmly hold the grease nozzle onto the zerk fitting or grease would squirt out from the side of the nozzle. The passenger side lower ball joint was completely blocked and could not be greased at all. I removed the zerk fitting and it checked out OK. Then I removed the base to the zerk fitting and inside the ball joint could see a circular impression where the base fitting had bottomed out in the grease channel. Using a diamond blade on a dremel tool I cut notches in the base threads. That solved the problem and I can now easily lube the lower ball joints. These Moog ball joints were installed new a few years back. If I had inspected more carefully the first lube job the blobs of grease around the zerk fittings would have been obvious. Fortunately the ball joints don't have too many miles.
