Don't do the aussie locker in the FF axle. Go with a selectable locker, either an e-locker or an ARB.


here goes.....
if you did any rock crawling, then i would'nt install a FF rear if you paid me to.
yes, the weight carrying capability is better when it comes to a FF rear. however, how much weight are you going to pile in your 60? if a sf rear in a similar seized rig ( with a 450hp supercharged vortec ) can hold up just fine, then why would you want to change it?
when's the last time somebody on here broke a sf rear? i bet it's well below 1%. well below.
now ask the guys that run ff rears. i bet more than 50% of them have broken shafts. even the "better" poly shafts. most people with FFs carry spare shafts. guys with SFs don't.
silly. just plain silly. i would'nt run one in my rig.
if none of that convinces you, then how about this: how many miles are on your 60? 260 plus thousand. right? when's the last time it had a rear axle issue? ......... yup. i'll stop now.

I was seriously considering rhino-lining the entire floor black but after talking to Dynosoar I'm kinda rethinking it and may go with cruisercrap butyl then padding and then upgraded carpeting.
Were you talked out of it based on noise level? I'm curious because I've considered the liner route for my own much uglier 60.
I'm in the "1%" that G mentions, but I still agree with him. When mine broke, I was locked and bound up under a ledge on the Rubicon. PIA to fix on the trail and many swear words were said.
If you want a FF because you fear breakage, spend the cash on a really strong axle like a 14 bolt, a Dana 70, or a built Dana 60. A 14 bolt in particular will save you large amounts of $$ vs a Cruiser full float and will be essentially unbreakable. They can even be had with 4.56 gears and Detroit lockers from the factory. Usually available on Craig's list for $150 or less, and an easy disc break conversion is as close as the local parts store.
Georg is right about the FF. Had I been more informed about it before I spent almost $800 to buy and rebuild mine, I would have stayed with the SF for exactly the reasons Georg mentions.
But, you know, if there is a way to break a SF axle, your wife will find. It...
Come get the AC compressor.:
If you wouldn't run one in your rig, then would you take out a FZJ80 rear axle and replace it, right off the bat, with a FJ80 rear axle to go back to a SF design?
Not trying to be a dick, just picking your brain![]()

I went to FF when after 285k the SF in my 60 had it's rear wheel bearing eat the axle shaft. I don't know how much the PO's "wheeled" it, but it has obviously seen a lot of Sacto. Delta area dirt roads. By going FF $$ out of pocket I was ahead of fixing what was there.
