Suspension Noise

[Outbumn]

Coming back from Charlotte Monday we hit a bumpy stretch of I-85. Now, when we turn or stop, the chassis creaks and at low speed, ( <20mph), there is a rhythmic thump. Crawled under and checked everything with a flashlight and can't see anything loose.

Any ideas before I take it to the dealer?

Our '98 P12 is basically a W20, and it
had what the old Guys around the campfire
called "spring slap". The Workhorse folks
installed plastic/delron/teflon pads at the
ends of the spring leafs to quiet them. Well,
that works but sometimes the pads don't stay
put. They come out. What I did was filled a
Walmart pump oil can w/flex spout with
Dextron ATF and ran the HWH levelers down
to off-load the springs and spread them a bit.
Then I squirted the ATF in those spots where
the spring ends had been rubbed shiney. I also
had a squeeky noise that I thought might be
coming from the poly bushings in the Davis
Tru Track front bar, so I douched them, too.
The rear sway bar bushes got F-21 tire
shine on them as well as the shock bushings.
Took all of about 15 minutes...

The result? She's stone quiet

Update on the noise. It was not suspension related. It was our slide-out. The dealer told us the solinoid went out and the slide was not fully seated. He told us it would not have extended while traveling, thank god....

The part is on order and we will be on the road soon.
