Warn hub fuse
Does anyone have them? Running 35's on IFS I am a little worried about my CV's. Is this a good way to go. There 20 bucks, pretty cheap.
Does anyone know what force it takes to break a CV? Warn says that a standard hub breaks at 80,000 inch pounds, and the Hub Fuse breaks at 46,000 inch pounds, 10,000 inch pounds before a 297x U-joint, we we dont have u-joints...but the same principal applies, providing out CV's are stronger than 46,000 inch pounds....
WATRD, did you ever do any research on these in your IFS days?
Any help is appreciated

My understanding is that it really takes quite a bit to actually break a CV. Locked, full droop, turning hard, and heavy on the skinny will do it though, and hubs are so much easier to replace!
I have seen them, but didn't know they were only $20 - definitely a good idea!

I run Warn hub fuses in my D44 and love the peace of mind they give me. I have only broken one so far and I really had to TRY to do that.
But, I have not seen them for Toyota applications, IFS or solid.

That's an interesting idea. Where does the "fuse" go?
I thought about this sort of thing with winch cables. If you put a link in there that was a good bit weaker than the rest of the cable, and then had a weight on the length of the cable, if it popped you would know exactly where it was going to pop and the weight would keep the cable from whipcracking and killing someone. Pretty simple idea, I'll probably forego a patent application this time

The fuse is basically a weaker ring that will sheer at a known amount of stress.
In this picture, you can see how the inner splines are greatly reduced in size;

As far as your winch cable solution, there's an easier solution. Just use synthetic rope and no one gets killed.

Stretch is for recovery straps. No stretch is for winch line and tow straps.

I hereby stand corrected and educated!
That makes alot of sense, since there's no stretch, the E = 1/2*k*x^2 has a small k spring constant and small stretch distance x, therefore small potential energy in the rope.
A physics student ought to have seen that right off the bat

Just got off the phone with Warn. The hub fuse has been discontinued. The reason behind this is it wasnt working as well as planned (i.e. U-joints still broke first). The tech said that when the wheels were turned to full lock the u-joint was much weaker than the hub fuse. When the wheels were closer to straight it did work as planned. I guess they stopped making it about a year ago. They still have the info on the website and there are some places with some in stock, but once their gone their gone.

*sigh*
Did you really just post that?
There is ALWAYS a weak link. It's just that most people don't know where it is until it explodes in shards on the trail and they have to limp back, if not worse. This way you know where the weak link is and are prepared to repair it. It has been moved out of the differential where it is difficult to repair in the field and potentially expensive.

Doesnt everything have a weak link? Personally i like knowing the weak link is easily replacible, and not catastrophic.

totally realized that, about 5seconds after hitting 'post reply'. My stupidity, i assume all things found when searching were posted to less than 10 minutes ago.... maybe i should stop assuming that.
