Shock, Rattle and ...

[chris cross]

I've still got the rattle (vibration) coming from under the flooring by the front axel. After checking every single nut with a wrench, I'm guessing it has to be the shocks. Previous posts have compared the Bilstein to Koni, with Koni seemingly getting the nod. It was not easy getting the Bilstein # but here it is. F4-B46-2093. This compares with a Koni 88-1458SP2. I don't know jack about shocks but I hate rattles. If anyone out there has any input on this for me, I will be most appreciative.
Thanks

Did you check the wheel well. See if the brackets have come loose.

Hello Chris:

I too have had a rattle at low speeds in the front axel area that I have not been able to locate it and I am still looking for it. I have checked all of the nuts and bolts and I am pulling what little hair I have out in search to the rattle. If I find it I let you know.

Chris,

Here are the shock numbers I got from Mark at WRV. Bilstein front B46-2092 and rear B46-2093. Koni numbers 88-1547SP1 and 88-1458PS2 respectively. These are numbers for a 2005 36'. Yours might be different. One thing I'm sure going to check before ordering the Koni's is that the mounting brackets at the bottom of the shock are correct .
For now Patty and I are still trying to figure out what brake system to use on our first toad .

I have been chasing the rattle inder the front steps for 16 months on our 2005 40FDTS. I could have sworn it was the front steps and have had them adjusted quite a few times to no avail.

In July, I had the coach in Yakima for a few items and again complained about "The Rattle". Fortunately for me, one of the techs that went on the road test had heard it before. We stopped and he got out, grabbed the wheel well cover just in front of the right front tire and gave it a good shake. It made the same sound.

The wheel well cover, just behind the door and in front of the front right tire, is attached by two brackets to the structure in front of it. The brackets are bonded to the fiberglass. He said the bond can fail, causing the rattle.

They rebonded the brackets and, miricle of miracles, the rattle was gone.

One more mystery solved. Good Luck.

I too have the same rattle in our 03 40FDTS. I really dont think its the Shocks. By the way I understand that the shocks have a lifetime warrantee.
anybody confirm that? Also I wonder if it could be the Onan generator bouncing on the rails?

Stretch - I believe the shocks sold to OEMs do NOT have a lifetime guarantee for the coach purchaser. Only the shocks sold to the original purchaser have the guarantee. So, if you replace the shocks (buy new ones), they will then have a lifetime guarantee for as long as you own the coach.

Chris- IIWM, I'd keep looking prior to replacing shocks. There are 3 years max on yours, & they should give better service than that (you can always get a bad one that breaks, but that's rare).
Most likely something else, & you should keep looking.

I had a rattle and found out the panel that is in the wheel well that hits the body panel was ungluded. Saddleback used resin and fibergalss to stick them together and it went away. The ratrtle sounded like it was coming from the door/front panel.
