Vibration under load
About half-way into our 3000 mile trip I started noticing a vibration climbing hills. Suspecting U-joint problems due to other posts, particularly late model Alpines, I bought a grease gun and Lucas #2 Red & Tacky grease. I performed a grease job in Zion NP, which seemed to resolve the issue. Later in Yellowstone, after a drive on dirt and gravel construction for miles, the vibration was back worse than before. Another grease job in Yellowstone didn't help. Now I was noticing vibration when the jake was slowing me, along with climbing, and even just driving on level freeway. I finally couldn't take it anymore, and stopped today (Sunday) at Missoula Freightliner. The attached picture shows the damage to one of two U-joints. I had them change both, to be safe.
Less than $300 later, and another WRV issue is resolved. Hats off to Freightliner for 7 day service bays, and for getting us in with no appointment on a Sunday afternoon. We were in and out in about 2 hours, and they were busy!
The tech recommended greasing the U-joints every 5k miles. Our coach had 5100 miles on it at the time of repair. I greased the joints at delivery (1900 miles), and then 3 additional times. The assumption is WRV didn't grease them well, and once the damage had begun, no amount of additional greasing would stop the destruction from continuing.
I didn't know I needed another project.
