Seneca Leaning

I know I have seen others post about their Seneca leaning. When I was in for an oil change last month, and the unit was on a perfectly flat pad, I noticed my unit Leaning to the drivers side. Today I took it back to Freightliner for the front end alignment and to address the leaning. I am trying to get as many things addressed before warranty ends this Sunday. I just completed my discussion with the service writer. I a do not completely understand what I was being told over the phone (more of a visual person) but what I thought she was talking about was that the entire frame of the Seneca has twisted. This truck has never been in an accident, is not overloaded, or has ever towed a heavy trailer. Moreover, I have never used the jacks to compensate for severely out of level ground.

I have requested Jayco and Freightliner to come together over the phone to discuss this issue and find a remedy. Admittedly I find myself concerned about this. How could the frame of this truck been twisted?? How can it be put back without damage?? I now feel I understand why the steering is such an issue.

Has anyone rectified their lean? Any opinions are appreciated.

Javamon, thank you for referring me to the correct posts on this issue; much appreciated. So apparently there is a shim kit for the front axle. Am I misunderstanding something or would that still mean the frame is twisted??

Clearly it does matter which Freightliner dealer you go to as this one said they called Freightliner and they placed the blame on Jayco. I am finding it hard to believe that the fridge makes it lean. Also, this issue is new as I had not noticed it before.

Ryan,


Sounds like a bunch of BS from Freightliner. I would recc. contacting Jayco ASAP (since you said your warranty is about to expire) and get this documented with them as well. I'm sure this has come up before and Jayco will hopefully be able to help get this resolved with Freightliner or at least put you in contact with someone at Freightliner who knows what they are talking about. Follow the suggested links (previous emails) and you will see some have had shims installed to correct the problem. Let us know how it goes.

Contacted Mitchell Grooms with Jayco before first posting about this issue on Monday; no reply to this point. Freightliner contracted rep with the company to inquire about shim kit. Many hours holding our breath as they had to take measurements to ensure shim kit was appropriate. Currently parts are being overnighted to Freightliner and are scheduled to be installed today.

As this lean was not present on delivery I still don’t understand how this occurred.

It's good Freightliner is now stepping-up. If the re-shimming corrects the problem it would be nice to know how/why this occurred and where exactly they are placing the shims in case this happens to someone else. Please let us know when they get done. Good luck!

According to Freightliner, the front end had the drivers side 5/8 lower than the passenger side. These measurements are made to the frame rails. The solution was supposed to be a shim under the axle drivers side front. They calculated that they would need a 1 inch spacer to get things back to normal. Unfortunately, the service bulletin on shims states that only up to 1/2 inch can be added without distorting the geometry of the engine and driveline components (and probably slide outs for us RVers). The 1/2 spacer was used and the front remains 3/8 inch lower on the drivers side with the lean persisting. Jayco finally got back to me this morning and they are looking into the cause.

While I do not have the engineering knowledge that many here do, this sounds like something that needs to be corrected permanently to avoid problems down the road (literally). I feel this could progress to cause binding of slides or issues with driveline components.

I will post back on this when Jayco provides more information.

Did they check out the front springs? is the drivers side front spring defective?

Steve, they “said” they looked at that possibility.

Ryan, Our prior Class C had a similar leaning problem... I took it to a spring/suspension shop thinking that the rear springs were the problem with the leaning. They looked it over and replaced both of the front springs (coils on a G30 Chevy Chassis) and the entire leaning issue was fixed (did new shocks at the same time).

The next year, because I was so impressed with the work they did, and how little it cost me to fix - I had them take the Hellwig overloads off the rears, and rebuild the factory spring packs of both leaf springs with a progressive rate pack with greater capacity... It rode like a Cadillac for the next few years until we bought our Seneca.
