Thanks to each and everyone of you. I learned a lot. I did not notice the missing rubber boots for the brake adjustment. Should have known I adjusted a lot of brakes back in the sixties. I had no idea that there would be rubber inside the axle tube. Wow this old dog needs to do more reading.

Thanks a million everyone.


Sincerely,

Yeah, it is basically a rubber spring system. There are a few different versions of such suspensions out there.
Like everything, there are pros and cons.
Pros: Independant suspension and a lower ride height. Pretty much maintainence free, for quite a while.

Cons: Lower ride height. (yes this can be good or bad)The rubber will eventually break down. Rubber ages even when not being used. Some use is good, as it keeps it limbered up (so to speak) too much use will accellerate the wear. There is a sweet spot in there somewhere for maximum life... Just cannot tell where it is. When the rubber deteriorates, the cheap fix is to have the setup reclocked. But this doesn't have a good track record. The old rubber is still in there, so it just doesn't hold the adjustment well. The rubber can be replaced, but this can cost almost as much as new axles. There really isn't a cheap repair on this system as there often is with traditional suspension.

Not making a recomendation either way. Your money, your choice

Thank you for the info. Here is the photo I wanted to show. The formed steel angle looks some what light for twisting and turning the travel trailer

Looks very similar to my camper with similar axles. No problems over 7 years.
