I need an inexpensive 3rd member that I can disassemble to build up a unit with 4.88 and an ARB in it. Thanks

One of the 4.11's I got from cruiserparts.net was making a really bad clicking sound, so it is just sitting in case I feel like rebuilding another one. If you want it you can have it, if that would work for you. I certainly wouldn't want to give it to anyone without it being rebuilt.

Now that I think about it, I also have 2 good 3.73 diffs, one from the front and one from the back.

The one with the bad clicking sound would be perfect. The noise has got to either be a bad bearing or a bad gear set and I'm replacing all of those things. What do I have to do to get that unit from you?

You can just have it, I can bring it to the next meeting or if you need it before then I'm sure we can work something out. I work in Englewood if you are ever stopping through there.

Is it available today or tomorrow? Give me a call on my cell at three oh three three one nine eight nine seven six so we can work out the details. Thanks!

Sure is. I'm in Aurora (225 and Mississippi) if you want to stop by, or I can bring it to work tomorrow if you would rather stop by 25 and Arapahoe area. I can call you after work to go over the details if I don't hear from you before then.

If you are building this for a 80 series, I would stay with a 80 series case, it has better oiling and more support in the housing for strength. I have even used a 80 housing in a 40 and 60. I would not step back wards in case styles if this is used for a 80 series LC.
Good luck find one.

Randy, since you are regearing and wouldn't care about coarse spline pinion, I have spares you can have for free.

Jeff,

Satchel fixed me up with a rebuilder unit. But next time you come down the hill, bring em with you if you just want to get rid of em. Having rebuildable cores around is always a good idea.

I keep them around in case I or anyone needs one. I think I have about 3. They all work and are fine as trail spares. They're all 4.11, coarse pinion. One of them has coarse side gears even :hill:

I even have a pair of coarse rear axles to go with it in case anyone wants to "upgrade" to the "vintage" design :lmao::lmao::lmao::lmao:

I don't need to get rid of them, they don't take up much space in the garage and they are handy to have around. It would be nice if I had a pair that already had fine pinions, I'd love to re-gear the 60 to 4.11 but don't want to have to buy a gear set for it. My 40s are both already coarse so they're fine as spares for them.

Bumping this up as I'm replacing the lock-rite in the rear of my 40 with an ARB. Jeff, can I grab one of your thirds so that I can install the ARB without having to pull mine out of the truck?

Of course Ricardo. What are you doing with your old Lock Right? (Hint Hint) ;)

Will do:thumb: Actually, I'm not changing gears so I just need to move over the ring gear - though I'll likely end up replacing the pinion bearing since I'm in there along with new carrier bearings.

Excellent, I'll give you a call to work out the details. :D. TheBoomBoom has his eye on the lock-rite for his truck.

TheBoomBoom has his eye on the lock-rite for his truck. I thought he had a mini truck? They use a completely different Lock Right than the one for the full size cruiser diff.

I completely agree! The 80 drop out is stronger and better but lately have become expensive as salvage yards have learned! If its going in a 40/55/6x series for normal use any (real :p:) Cruiser rear drop out will work fine. If it's an 80 I would not go backwards or if your going for performance than you really want the 80 rear non-elocked drop out

I believe they are compatible, but I suppose we'll have to double check that.

Yeah, but it looks like there is a line forming; TheBoomBoom, Mr. Zepp, Mr. Kaiser...

Nice information, in my case it is going into a 40.

So if I were to put my 2 :drumsticks: 80 Rear 3rds in the 40 I just have to change the housing? I don't need different bearings or a different ARB unit?

Dr. Schlegs
10-07-2011, 01:09 PM
Sorry we are Highjacking your thread Ricardo. If the plan I have will work, I will yank my 40's rear 3rd member (4.11 and ARB) and you can have it. Just get me another ARB to put in an 80 housing for the 40. I could do that Tonight or this week end. Ask Randy the 40 isn't going anywhere anytime soon. Oh and Rudy built my rear so you know it is good.:lmao:

You have 2 80 rear thirds? NO they wont work and you should sell me them for $20 imeadiately!!! OK I'm lying but if you do have set up 80 thirds, yes, they will drop directly into your LATE model 40 housings. (late referring to 30 spine axles) I have found that the jig used is slightly off on the mounting bolts but simply running a 3/8 drill through the holes on the 80 drop out will clean them out enough for it to slide right on the 40/55/60 housing studs. The pinion flange will be a different pattern. You can buy different flanges or if your lucky enough to have post 78 40/60 drop outs you already have fine spline flanges so just swap them. Again, if you are lucky enough to already have the round pinion flanges then you simply just rotate the drive shaft 45* and drill the new pattern into the round flange. (note: round flanges are the holy grail of flanges!) ALL Toyota drive shafts are hub concentric but several different bolt patterns are used. (meaning the raised alignment "hub" on the drive shaft flange is the same across the board)

Clear as mud?

They most definitely are not. Full size Land Cruiser diffs use model 1630, pickups with the 8" diff use model 1610. My daughter's '85 runner had one and when I pulled it and held it next to a LC Lock Right it was visibly smaller. There was something else that was different but the detail escapes me at the moment. I remember the 8" diff uses a roll pin instead of the bolt-retained cross shaft, but that wouldn't matter for the LR itself. Also on the mini truck the c-clips are on the wheel end of the axles at the brake backing plate instead of inside the diff.

Speaking of Holy Grails.....I have it from reliable sources that someone in the club has a uber elusive and thought to be a myth by many, 1984 FJ-40 with factory A/C and power steering! :eek: Maybe this post will flush out this precious mythical gem and it's equally exalted owner. I can only spread the rumor as I am not worthy to actually witness such dynasty. ;) :D

I saw and touched one about 18-19 years ago. It was FS, in the parking lot in front of the Evergreen Safeway. Freeborn red, it had a quarter-sized spot of rust on the rear sill, otherwise was immaculate, bone stock and unmolested. It had about 50k miles and they were asking $11k. I wished I had the bucks, man that would have been an awesome rig to own and drive!

Yeah, they guy definitely knew what he had. On the sign in the window he said that it was one of only 600 imported.

There's a guy on the LCML in Christianchurch NZ who has a 1985 FJ40. With drum brake in front, just like all the rest of the world got through the end of the 40 series run.

No I got it. Just trying to make a funny.:D My Ford Mechanic thinks I live too far away, but he is always willing to drink beer from the kegerator. Don't worry UB I have spilled a lot of blood in my day back in MN. It is nice to have people around to bounce ideas off of and to give guidance. I converted the brakes on the 40 with only information from the web. Now I have been given suggestions of how to improve it. I'm kicking myself know because I have to rework much of it.

Um k, so now hows about the front axle of a 40? A 80 rear diff will slide into that as well?

I know this is kind of a dumb question. :o I know the 40 diffs are no different front or rear, but just want to ask in the event there is something I am not taking into account.
