Apparently the stuff I’m just used to seeing broken on a regular basis is big news to some people. Going to start keeping a photo diary of all the stuff that gets broken around me. Bump this thread every time you’ve got something broken to share.

Broken hp60 in the rear isn't a big shocker.
That ried c is pretty impressive though.
As far as the gooseneck, did it break right next to the weld for the gusset? Was it way over loaded since "I'm only going a few miles"?![]()
yes and yes. I didn’t get to join in the rescue but I’m told. Dad didn’t have any air in the airbags. Hit a dip that caused the rear suspension to bottom out and the weight had enough inertia to clean break the C channel. There was no signs of fatigue, the break started at the HAZ at the gusset. It’s at welding shop getting a whole new tongue put on it now
Damn. Alfalfa bales?
2.250 7075 aluminium link with 1 1/4” shanked rod ends. Came down on a link, broke the link in half and broke a 1 1/4” chromo rod end shank. Broke the coilover too.
Only Yukon joint failure I know of. Spidertrax 1 1/2” 35 spline 300M shafts. Hard to say but not enough grease?
What is the normal grease interval on the Yukons for go fast use at the Hammers? I hear once a day for rec wheeling, and I doubt that there is time to grease during KOH race day. Wonder how dry they are after a long race?

Impressive straight demarcation on the right side...
what's up with that?
Or did I miss sumthin?
This one is cool to see, right at the stress riser going from solid to the corner of the drill. The pealed away end looks like a piece of fruit. 7075 in that size is crazy strong as well. I guess it is super strong in bending but weak at the ends since the wall thickness is only .5" once drilled. I wonder if a 1" shank would have faired better.

We need more details on this please
Is it possible that it just took tons and tons of abuse and had enough? Or was it not in the car very long?
Since we never felt it break I think it had to be previously fatigued. Ryan thinks it was flipped over. As in used shaft, the unit bearing end got put in the spool end so it was spun the wrong direction from what it’s used to. There was no point we had something happen that we thought, uh oh, that had to break something. We just eventually found out we had 3 wheel drive. Broke on the first lap, did 7 laps with that clanging around in the axle tube. I only had to get out and winch once, Ryan beat the HELL out of that car the rest of the race to make up for it and keep it moving.
What kind of axle was that shaft being run in?
