Shock mount failure

[timvasqz]

I think the crack was there from off-camber HWH jack parking in the
past. looks like the temper of the weld proved a brittle spot that
under normal conditions would not have issue. Then the new shock
absorbed more bounce but reacted equally agressive causing much more
stress on the mount. I think the mount post should have less strength
and be a point that can bend at failure. the tripod gussettes are a
bad idea.

I think problems arise when the bus air bags are dropped to be
leveled but the spot is too off camber. the HWH push one side up
and tilt the axle too much. at that point raising the front is
effortless and and the 30 foot lever post all the stress on the
tucked tire.

If I was to repair that mount I would remove two bolts and make a
trapazoid shape cut and replace the plate with a butt weld then build
the post mount back no better than before.

If you lose an airline and must drive. there is a screw set in the
maxicam to turn off the parking brake. you can then plug the airline
and fold it over then tape it.

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!)

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.
