Hubs

[CheapThrillB2]

Yukon 4340-

5-760x Joint.....the cross shafts (center section) still had the one cap on it when i found it. The other cap was still attached to the ear of the shaft and the c-clip still on the cap. The other two caps were MIA

The break was instant, had a loud crack bang and then nothing. So it appears all the ears broke at the same moment. When i broke all my stock shafts, they made a god awful sounds of the stub and shaft hitting each other as it turned. With this failure, there was just the intitional bang and nothing, i thought for sure i had just broke the hub.

I have stock Hubs from a GM D44. They look alot like a warn hub inside, with the cast insert ratcheting peice. I honestly thought that would fail before the shaft or joint. I thought the hub would have been my weak point. I used to run the old ford style hubs that were pretty much unbreakable. I lost lots of shafts with those hubs. Are the Warn Premuims really that much weaker? I was gonna look into the Fuses but i have read they are discontiuned, and with chromo shafts the fuses will just break extremely easy anyway.

You must either be driving that thing like a maniac, or you have a problem somewhere if you're blowing up chromo shafts with 36s. Is your steering too extreme maybe? I was blowing a lot of 760s for awhile and it was because my steering was too extreme and the joint was binding. Maybe your tire got caught somewhere on the frame or body??

no, wheel wasn't turned. I was kinda on a slight hill side attempting to bump over a downed tree. It was a tight fit with a large dirt burm on one side and a tree on the other and many trees surrounding. Right when i went to bump it over i hit and slid sideways into a bunch of large trees jamming me up. Turn sout i wsa still in 2wd from a 100degree turn i had just made before this spot and forgot to slip back into 4wd. I engaged 4wd and began romping on the truck to get off the trees when the LF slammed into the dirt burm and BANG!! I thought for sure it was the hub, turns out it wasn't. But i had abused the front axle pretty damn hard in the begining of the month back at the Badlands in Attica, IN. And a trip prior to that. Abused the truck far harder on those trips then this last one. I was actually kinda of taking it easy yesterday. The ear the i recovered looks like it just snapped. Clean break in half. Now i'll have to pull my diff cover and inspect the Aussie for broken pins.

The hubs i am running are suppose to be weak. I thoguht that would be my first thing to break

Yeah, maybe it was already damaged from the Badlands. You should take your hubs apart and drill some holes in the engagement collar to make them weaker. That chromo shaft can't be cheap.

actually it should be under warranty, atleast i'll find out tomorrow

that could be a factory defect too, those hubs are super weak, but they should give long before a chromoly shaft would.

that was my thought, that hub should've went

its had to just be a crappy shaft, i didn't even break the pins in my aussie. I broke the pins in my last aussie with a stock TTB D35 when i broke a shaft.

Did you find out if you can get it replaced free of charge?

 

[CheapThrillB2]

i have a call into them, they are gonna call me back. I thin kthey need to get a return order number from Yukon before i send my shaft in. The guy on the phone said its a lifetime warranty and didn't even bother to ask how it broke.

Tell them you may just get superiors stuff instead and they usually will take care of you.

i should have my new shaft tomorrow. UPS refused to ship my old axle shafts "their might be hazardous materials on them" fedex shipped them no questions asked.
