2008 Utilimaster With Noises

[Keith Browning]

I have a pair of 2008 E350 stripped chassis Aeromaster Walk in Vans that make a heavy popping noise over bumps - Sounds structural. The noise comes from the right front in the cowl area and it disappears after the trucks are run for 15-20 minutes. Obviously heat is playing a role. I have checked the Ford chassis, all steering and suspension fasteners are properly tightened including cross member bolts.

 

I am using Chassis ears to isolate the noise and "somewhere in the right front of the body" is the best I can get from it. These things are actually well made but the screwy thing is that there are no body mount isolators at all! Solid aluminum construction with brackets mated directly to the frame.

 

Anyone? /forums/images/%%GRAEMLIN_URL%%/shrug.gif

I can't remember the TSB number Keith. But it was for 03', 04'ish superduty's with a popping noise in the body mounts over bumps. there was a bodymount isolator that you would put in to get rid of the noise. I am wondering if you could put these isolators into the body mounts of the units you are working on and see if it fixes the problem. I will look for the part number.

Two things, this is an E-series and yes, some things are worth experimenting with, but I cant with the solid body mounting.

Seems that TSB is obsolete and I can't find the part number. But that's what I was getting at: if you do determine that it is in the body mounts, it would have given you an option to experiment with and possibly fill out one of those lovely GCR's. But from what I'm understaing, your saying that's not an option?
