You're still using the stock 8.2" rear end right? What kind of magic material is Toyota making these diffs out of? I never broke one in my 4Runner (with a lot smaller tires), but I've blown up an old 9.5" running 40's, but on a 3800lb rig with only 120hp. I'm shocked that it's holding up to the weight and tire size you're running. Amazing. And - it begs the question to me if it's that strong, why does the Tacoma/4Runner hybrid need the 9.5? I can't imagine that they're putting more torque on them than you're doing wheeling it on 38s. Also glad to hear your experience with the steering. Really excited about relatively little work it takes compared to the last generation that took a huge amount of effort and modification to run bigger tires. Obviously you've done a lot on yours, but for the milder build with 35s or 37s - compared to having to swap steering to LC200 parts and cut up the fenders and all of that just to fit 35s, this is fantastic improvement.

I love seeing you get out and crush the trails! With the double OD transmission you can go pretty deep on the gearing and still have nice highway performance.

Difference in the Tacomas is they are not full time 4wd, so at times 100% of the driving force is on the rear axle.

Not saying it's a difference that means the Land Cruiser does not need the 9.5", but that's the difference there is.

I'm with you there. But I tend to think the failure point happens most often in 4lo on a steep climb where the weight is mostly on the rear axle and you get on the throttle a bit. In that case they'd be the same. That's where I've always broken differentials - either front end bound up in a hole trying to back out or rear axle on a technical climb.

But maybe it's a cooling issue when pulling a trailer or something along those lines that is really driving the larger size? That would explain the higher loading in 2wd vs awd models.
 
I've been out of the Toyota game long enough that I have no clue. What would be involved in swapping the 8.2 to the 9.5"? Entire axle assembly, or just the differential? Any difference in the axles themselves?

The front diff would also need to be swapped to match the gearing.

The housings are quite a bit different in terms of the diff fitment so you'd need to swap the entire housing. However - I think it would be a plug and play bolt in swap. I think the 2024 Tacomas that come with the 9.5 and the 4Runners with it will have the correct 3.58 ratio. So - once those are out, I think you could easily swap a rear axle only in a few hours and it'll probably be a relatively easy fully bolt on swap without having to mess with the front end. If you used a current 9.5 from the GX or LX - they are the wrong ratio so you'd have to do a front diff gear swap to match.

But - if it's not breaking with big tires on technical terrain - I'd be inclined to just run it. No reason to upgrade unless it shows up as a common failure point IMO. Bonus of the 8.2 is about 1/2" of extra ground clearance.

It’s still completely surreal to me that we’re having to discuss upgrading a Land Cruiser axle assembly to a 4Runner or Tacoma axle assembly.

Ben was extremely gracious letting folks crawl around this beast at LCDC 10 kickoff last night.

Thanks Ben!

It's been on a crash course for a while now. (Gen 1 in this is the Trekker so it's off by one generation in numbering). I can only assume the 7th Gen 4Runner (in the year 2048) will be about 115". These charts only ever go up and to the right until they merge into one product and then they introduce a new model on the bottom end and start over again. I guess that's the Land Cruiser mini?

1st Gen 4runner was 1984. The 1984 Land Cruiser was the 60... and 107.5" wheelbase.
You must be new here. All real land cruisers have 112.2" wheelbase. :)

I went back and made a new one with some trend lines. Have to make a lot of assumptions or it ends up too messy with every different WB version LC40/70. What I learn here is that the LC200 lost its way. Should have been 115" or so. Not really linear growth - probably more like logarithmic, but this is a 5 minute chart so - you get what you pay for. haha.

Been a crazy summer so far and I apologize for the lack of updates but last week we successfully completed the rubicon trail in the 250! Directly after 2 weeks of trails in Colorado we hit the rubicon trail and I have to say I am impressed! We made it through with no issues and it handled it quite well. We went with a group of very well built 80s and it hung with them just fine. Took some bypasses but also tried a lot of the harder lines that even some of the 80s opted out of. Everyone in the group was skeptical myself included but in the end we were all impressed with the performance and durability! I was also pleasantly surprised to find it drive straight and well after the trail as well.

Keep an eye on our ig and YouTube for more videos.

Don't worry about working and wheeling and thank you for the updates!
 
Swapping Tacoma CV to land cruiser would be a new trend and very disappointed with that. Along with swapping Tacoma/4Runner 9.5" rear diff. WTF is toyota thinking?

It used to be Tundra front suspension to 200 series.I guess I have new found respect to Toyota R&D in US. I always thought they would never design more durable vehicle than Japanese designed vehicle.
