It only affects the new (2014 and newer?) Greyhawk motor homes that Jayco installed the "J-Ride" package on. I got my information from the chief engineer at Hellwig, then the Hellwig dealer found that it had caused a failure. The shackle bolts were stripped out from the stress. There were numerous other failures on my unit that were not related to the suspension but all traceable back to poor installation quality. Ultimately Jayco fixed the problems with my unit. However I believe that Hellwig was told by Jayco brass firmly to not tell customers this type of information. It is sad when company takes the GM route. When the shackle finally breaks it could kill someone. From Jayco's perspective it could be out of warranty by then. The real problem is when the suspension goes through harsh road seams or pot holes. The shackles can become unloaded and rapidly reload.

I am posting on this forum because I care about my fellow RV owners. Kevin at Hellwig is correct in the amount of suspension support based on the adjustment however seems to be leaving out the rest of story from what I heard after the resolution of my issues. If the spring shackles are adjusted based on the GVWR of the rig it is impossible for the shackles to become completely unloaded during suspension cycling. Incidentally, Ford also looked at my rig when it was empty and noted the handling problems on their report.

Consider this scenario, you are driving your unit at or near the GVWR you hit a blind corner and at the same time there is an unavoidable pothole in the road. You hit the pothole and suddenly the outboard suspension fails because of the fatigue on the shackle due to the installation. Your rig flips over on its side. In the subsequent accident investigation they likely would never trace the accident back to an incorrect installation of the helper springs. The sad thing is the driver would be charged for driving "too fast for conditions" or some such nonsense. When really it was completely unavoidable due to the suspension failure.


Since it is very inexpensive to adjust them better safe that sorry. At minimum you will improve the handling and ride and reduce the likelihood of bottoming out on driveways etc. It is very sad that Jayco is muzzling the supplier. If you combine this with the incorrectly installed leveling jacks 4" - 5" clearance rather than 7" - 8" clearance per the installation manual. This isn't the only thing Jayco / Mor-Ryde installed incorrectly.

I would seriously doubt the 24SS would have any of these problems because it is such a short coach. As far as I know it is still on an E-450 14,500# chassis meaning it would be very unlikely to be at or near the GVWR.

Well, after much searching trying to find a Hellwig certified dealer within a day's driving distance... no luck. A truck suspension mechanic said that he "could" do it, but he isn't authorized by Hellwig, and didn't want to do it while the unit is under warranty. So, I'll just have to go slow and avoid uneven road surfaces.


And just to note, everyone who has looked at it agreed that it was not properly adjusted for a loaded unit, and has the potential to be dangerous.

Greyhawk01, have you sent those photos to Jayco?


Looks like we all need to check the water lines, having those helper springs misadjusted apparently can cause more problems then we knew.


Thanks for the info!

While crawling beneath mine today with a can of spray foam looking for openings to fill, I note that my Hellwig shackles do not appear to be tight enough. However I did make sure they are not rubbing on any water or electrical lines.

We bought our Greyhawk in August from our local Jayco dealer. We've planned to put it in their service department in the off-season for items noted during the PDI and on trips this Fall. I emailed them my work list last week, added a link to this thread and said, "Please verify with Jayco and/or Hellwig that the helper springs on the Greyhawk are adjusted to the proper heights for maximum load support." We'll see what comes of that. We are scheduled to drop it off on January 10th.
