85 Holiday Rambler rear tag axle setup.

[Scottew]

I have an odd duck to say the least. It is a tag axle rear suspension riding in coil springs. No airbags. The MH shakes over 50 mph. I have my suspects as to what it is but... I am curious on your opinions. Shakes the seat not the steering wheel

I will post pics also.

I think you should have a Mor-Ryde suspension on your rear axles.

It will look like this between the tires:


The coils are helper springs (placed ahead of the drive axle obviously).

That is true thanks. Anything special I should know about it?

The biggest problem area is the rubber springs themselves, as shown in the image I stole. They pull apart and/or sag.

Lots of information out there googling things like "Holiday Rambler Mor-ryde" finds lots of threads.

Here's an example.

(We had a 1997 Class C with the Mor-Ryde suspension for many years and nearly 200,000 miles....)

Thank you. You are correct. I do have Mor ryde.

So you have Mor Ryde with a shake? Not sure that makes any difference, just wondering if you've checked you U-joints? Possible dents or bruised areas in the driveshaft that might indicate damage from hitting something on the road?

I'm working on my HR tomorrow, I ordered new rubber shear springs from mor ryde and will be doing an install, I also had the shakes but it wasn't the rubber spring (but they are shot) Also check as mentioned by prev member, U joints, and the tag axle has torsion bars, check your base plates for the tag axles, for
broken welds, and rubber shear springs, my shakes came from frozen u joint it wouldn't flex as it turned, I have a 1985 HR imperial on a P30 frame. Hope this helps you out a little.
