Shock mount failure

[Don Bradner]

I'm the latest victim of a driver's side front shock mount failure. It took out
the brake line when it went. I was not far from home on the way back from Q, so
I limped on in (I know, in retrospect it was too dangerous, but I kept a lonnnng
following distance!)

I've used the local Detroit dealer in Arcata (Trinity Diesel) a couple of times
now for service, so I called them, and the service manager said he would swing
by for a look, no charge. He ended up removing the shock and the air line, and
said that he would come by the next time he was this way with a new airline. A
new shock will have to be ordered (the top bent/caved in) and they will schedule
an appointment to get it welded after they have that. Shock was 17 months old.

Don, that is a first for me hearing that. Is this a Koni?

Yes, it is Koni. The failure is similar to ones described by others here.

Earnie, check msg no. 35143, or do a subject search on "shock mount".
This topic has been hashed over several times on this list. Where have
you been?

Wow Don, did you really drive like that? That's gotta be the most
severe case of the dreaded shock mount crack that I've ever
seen on a Wide Body. There must have been symptoms, creaks,
popping sounds, etc. Oh, keeping some paint on the frame definitely
prolongs the life of those welds. I'd get on the phone with Ridewell
to procure a replacement for the spring perch and shock mount
component. I think that piece is a bolt on.

I'm not sure it is worse than others. The thing is I don't think anyone has
shown theirs pre-fix before. If you look at Pete Masterson's
http://homepage.mac.com/aeonix1/Sites-Pages/Image2.html you will see that the
tear is almost identical in location and scope as mine. In the Bumpersbird album
I can't really tell where the tear was (and it may not have torn off).

I'm not a metallurgist, but from the looks of the rust on the crack
edges, this failure has been developing for some time. Okay
everyone, it's time to crawl under your bus to check the steer
axle, street side shock mount for cracks.

Hi Don, sorry to here about the failure, can't help but wonder if
putting on shocks that dial-up the compression and rebound to improve
ride and handling, exceeds the design specification of the bracket, or
maybe it was a bad weld procedure. I know one thing, I will be keeping
an eye on mine!

I agree David. When it dries out around here I am gonna take a look at mine.

Marty,

Check out msg: 35125. This is a post I made back in June of '08
after I got off the phone with both Koni and Ridewell regarding this
problem on Wide Bodies.
