RED BUSHINGS
I know this has been previously discussed but I think it is worth mentioning. Red urethane bushings were used in several locations under our coaches, most commonly on the sway bar end links often called “dog bones”.
They undoubtedly work well, but their primary disadvantage is when they begin to fail by starting to lose chunks of the bushing they fail fast and completely. The end result is a loud clanging sound beneath the coach. I just did my normal maintenance and noticed the only remaining set of red bushings was starting to lose chunks. So I replaced the bushings with the same black rubber type used on our shock absorbers. I have never had one of them fail.
My guess is I would not have made it anywhere near my next service which is in another 5000 miles before the red bushings were gone and we would be hearing the dog bone banging around under the coach. At your next service, make sure your mechanic inspects them, and if there is any evidence the bushings are starting to lose chunks, just replace them. It is a 15 minute job.

At Jeff Rowe’s last week and replaced red for black along with steer and tag bags, rear shocks, pitman arm cover and engine, Auqa Hot and gen-set service. Found and fixed two water leaks in the salon area. What an asset to the Prevo community. It is actually a pleasure (almost) to spend money there.

We just did mine at Jeff’s and stayed with red, I won’t wear them out.

As often as you trade coaches, it is hard to imagine that you use up a roll of toilet paper, much less bushings. Those of us that keep our coaches for at least two tanks of fuel have to think long term.
