M2 Front Sway Bar Bushing Failure

I was on the Forest River Dynamax Forum, and there is a 12 page discussion about the M2-106 Front Sway Bar's upper bushing failing. It seems like Freightliner has know about this since at least 2010 when they came out with a Service Bulletin #32-47 (Heavy Duty Front Sway Bar Installation) to correct the problem, but it seems that they oped to use up all the old parts before changing over on new builds. I crawled under the rig an hour ago, to check mine. They seem ok, but now that I know of this possible problem, I'll keep a closer eye on them.

This issue came up in a thread a few weeks ago. I found my 2018 to be faulty with only 2200 miles (I did not forget any digits there). Seams dangerous to me.

Freightliner replaced my sway bar and bushings last year under warrentee. The new sway bar is noticeably more stout than the original. Bushings are completely different.

On my way home, 80 mile drive, I could notice a distinct improvement. No or very little road sway. Very pleased.

Seneca M2 Sway bar vertical link bushings

This thread has been very helpful as I too have replaced my sway bar vertical link bushings connecting to the frame five times. In each case the bushings are gone in less than 2000 miles. I called my local Freightliner dealer (San Diego, CA) to find TSB-32-47 costs $2,577.73 to replace the existing sway bar with a new larger one attaching hardware and new bushings. I contacted and suggest anyone with a M2 chassis to contact the DOT through safercar.gov filing a complaint for excessive roll and vehicle steering. Freightliner issued this TSB two years before Jayco started using this chassis knowing the sway bar was inadequate for our application. The purpose of all of us filing complaints is for the DOT to force Freightliner to issue a recall to repair the poor design on their dime not ours.

I brought my Seneca in to local Ft. Lauderdale Freightliner dealer for its first service yesterday. I had a printed copy of TSB 32-47 and asked that it be done. I'll post what happens.

I also asked about the low fuel light coming on with 30 gallons remaining in tank. Service writer said there is a new sending unit but it was not covered by warranty. I decided I can live with the gauge since I rely on my scan gauge more than the fuel gauge.

Just checked mine and they look fine and I'm approaching 10k miles. I'm going to try to get them replaced anyway. Got another long trip planned for Feb.

I had the senders replaced under warranty and my coach is a 2016.

Did the new senders make it better?

Don't think so (posted my impressions on another thread). Gauge is still way too conservative, so like some folks here, I'll rely on the Scan Gauge trip functions to monitor correct fuel status. Given the ubiquitous presence of M2's on the road, I guess most of their professional drivers don't care about gauge accuracy.

My sway bar upper bushings failed at 25,000 miles ( on a 2014). I took it to Ocala Freight Liner and was told that Freight liner would not replace the assembly. I asked about the service bulletin but got no where. They told me that if I chose to upgrade to the new version it would cost me over $2,000.00 to do so. It does not seem right that Freighliner knew about this issue and kept installing faulty parts. I was looking for contact information for Freightliner but have had no success so far.
Ocala Freightliner did charge me $400.00 to replace the bushings, I am not very happy.
