What FJ axle do I have?
I traded a 240 I had for this truck. I usually always buy stock and build myself but this time around I had no place to build and this truck is pretty much exactly the way I would and have built past Toyotas. Anyways im unsure about what model FJ this axle came out of. Im thinking 60 but im not sure. Has normal mini truck hubs and 30s that I installed which all fit fine. Only noticeable difference is the larger diff. Just curious what model you all might think its from. I need to order a new locker and gear set. Im pretty sure all FJs were 9.5 but again im not 100% on that. Any input would be cool.

Yeah its strange. One of the only I have found online that has a completely round diff cover. Most have an indent for the ring gear. Just curious on what model it might be. Yeah the truck has a few little things here and there that need to be addressed.

yeah thats true, I've only ever seen them with the indent for the ring gear. It could be a 9 1/2" pipe cap welded on there? Before companies like TG came out with diff armour, guys used to weld pipe caps on the diff to protect them.

Your axle has a pipe cap welded to the front... and no fill plug, which is interesting. If you measure the axle WMS to WMS, you could figure out what model LC it came from. That being said, all SA LCs have 9.5" ring gears (which answers your question).

I feel like I'm crazy here but is that a high opinion diff installed upside down? It looks to me that you have a mini truck axle with an 8" high pinion installed like a low pinion.

Your crazy or maybe drunk? You couldn't flip a high pinion diff, or any diff for that matter unless you can figure out how to make the front driveline rotate the opposite direction. Your front tires would spin backwards. Dont feel too bad, I thought I had this genius idea too, flip a diff to make it a high pinion. I presented my idea to the legendary ZUK where apon he schooled me on basic physics. One of those "oh duh" moments.

Dude i realize that completely but look closer at the picture it looks wrong. And he says it needs a new locker and gear set. I have never seen a diff hang lower than the housing like that. And I can't find a comparable housing that looks like that in a low pinion. I know how this stuff works I have gear swapped myself to 4.88s.

I'm pretty sure the bottom of the housing has been "clearanced". I know why the front diff is bad. My axles and all that when in and out just fine multiple times too. Its definitely a 9.5" R&P as well. I just wasn't sure which model FJ it was. Guess ill never know haha

Fins on a 1985 FJ60 (upper fin was flapper
sanded down on mine for clearance related reasons)
Note how thick the fins are on a 60 compared to a 8" 3rd.
shape of the 60 cover.......also has vented disc (Mine is a flipped 60 so no drain plug)
Actually....I'm in the wrong thread my goof.......
Your axle pics are actually pretty good....
But closer inspection of them shows it to be a typical 8"
fyi

Ok so im stupid lol Turns out its an 85 axle. Someone cut off the factory diff cover and the bottom of the housing. Plated the bottom for clearance and then welded on a pipe cap for a cover. Look at the bottom truss. The axle uses a normal 8" diff. Sorry for all the confusion! haha I was told FJ axle when I bought it and the pipe cap kinda had me going. But Im glad its not an FJ and that its an 85!
