100 Series front diff/axle swap

Why was that again?
Has your front diff actually failed?

Hi Mike,
Wasn't it that the IFS front diffs are only known to break in the V8's? Not the rigids

Another thing to consider is that the actual wheel studs in the 80 series have got a reputation for snapping in heavy four wheeling. In the 100s they were increased from 8 to 10mm diameter to remedy this.

I may be wrong, but aren't they the same thing? The 80 has a smaller front diff (7 1/4 inch?) with a high pinion. What would you really be trying to achieve? Are there any real stats on how many 100 series diffs have failed, or is it all ".....I have a mate who knows someone...." My understading is they tend to fail, under load, in reverse, with the front wheels turned and a locker engaged.

I think the rationale for the 5 stud-6 stud swap was probably driven more by $$$$ than being stronger. I've never seen broken front wheel studs - a CV will let go long before a wheel stud if they're tightened properly.

If you are worried about the front diff failing, I believe fitting an Airlocker will 'toughen it up'. Would be cheaper and you would have a locker too.

Topend.

You don't have to drive a 100 like you stole it to break the front diff. I broke one winching up a wet track with ARB locker, the vehicle was under very minimal load. They are weak and that's a fact!!

We have a guy in our club who has a 100 with front and rear 80 series diffs. From my understanding they are a easy swap without major mods. The 80's front diff is a better unit, how many of these have you heard of breaking compared to the 100??
