Suspension noise
When I hit the brakes on my coach I hear a clunk or knock which sounds like it is coming from somewhere in the front suspension, or where the wheels are. I mentioned it to Freightliner when I had my first year PM done and they said to see if it still does it after the chassis is lubed. I still do notice it and was wondering if anyone else's coach does this and if it is normal or not. I am still under warranty so that is not an issue but don't want to bring it in if it is nothing.
Thank you
Jason

I hear mine do that every now and then. There was a thread on the Tiffin site about it also. I do not believe there was a fix for it. I'll see if I can find the post.

Might be a sway bar that is binding in the rubber mount. Look and see if you can spray some silicone on it.

It sounds like the 'S' cam needs lubrication. Are you sure that it is from the front? If it may be from the rear, this could be your problem.

I had that same noise. It turned out to be a loose bolt on the shock absorber. I tightened it up and all is well. Hope that works for you. Ken

Yes. Mine was the drivers side. Go under the coach behind the wheel. You will see it. The lower bolt was loose. It took a 1 1/4 socket if I remember correctly.

They were all tight from what I could tell. Just drove it 600 miles round trip to Charlotte for the race and it makes the noise still when hitting the brakes. Other than that rides fine and no noise... Sounds like definitely something in the suspension but not sure...

Had a front shock absorber lower mounting bolt lose on my 2013 BH390 when I bought it too. Took it to Freightliner and they were no help so I crawled underneath and tried to shake anything I could. Found the slightly lose bolt, tightened it up and all is good now.

Yes mine was the same. Couldn't tell it was loose until I put a wrench on it and got a full turn. I hope you can figure it out. Ken
