Great info. Thanks. I am nervous about buying this new model.

It didn't seem like you were in the 100 or so posts you've posted in this area of MUD....

 

[4WD Toyota Owner Magazine]

Straight from internal Toyota literature. I copy it here word for word.

"The differential carrier and intermediate tube on the front differential are made of aluminum to save weight.

A double row bearing is used for the front bearing to reduce friction loss and improve fuel consumption.

Low viscosity oil is used in both diffs, also improving fuel comsumption.

BD24A rear diff is similar to those in Tundra full-size pickup."

"Similar." Hmmmmmm.

New information (like this) comes out every day (doesn't it?).

Test drives off-road just came on (didn't they?).

If toyota doesn't deal the deal is off until they do.

Wow, how things can change.

John,
I am glad you are willing and able, we will all enjoy watching your new build up.

I'm changing my mind daily.

I tried to buy an 07 Friday in Sierra Vista. It was sold. We went to Precision Saturday because I knew they had a nice tan one. It' was $67,000+ because it had all the stuff I don't want (AHC, NAV, $2000 wireless headsets, etc).

So, the '07s are gone in my area. I think I'm not willing to pay that price for an '08. So Jack, I don't think a build-up is coming. My excitement has dwindled.

I'm sure they mean the 3rd member housing, which is what holds the carrier and gears, etc, and then bolts to the axle housing. Sometimes the entire 3rd member is referred too as a "carrier".

If you've ever tried to pull out even the 80 series rear 3rd member, it's extremely heavy. I'm sure the Toyota Tundra 10.5 and probably the new Land Cruiser 9.5 diff would also be even more heavy if were made out of the same materials.

If they did to go aluminum it's probably less about overall weight savings and more about less stress on the bolts that hold the 3rd onto the axle housing. It could also have to do with keeping the unsprung weight of the rear solid axle as low as possible.

Toyota has been using aluminum for some front IFS diffs for a while and haven't had too many problems that were directly related to that. I think a lot of sports cars also use aluminum diff carriers.

I think aluminum also has the advantage of radiating heat better, which is something useful for a rear 3rd member, especially with huge gears.

Of course, given Toyota's past experience with the FJ, Tundra and Tacoma break downs and design flaws, I would never buy the 1st production run of anything including this new Land Cruiser. Even their original 100 series had flawed design front diffs. So, whether or not aluminum is a good idea is hard to say. It all depends on the design, how thick, what type, etc.

Only time and experience will tell. I'd let someone else be the guinea pig.

Toyota never did make a dependable 100 front diff. Plenty of ripped R&Ps from '00 out there.

John,
Just go and place an order for one, you've got the cash, you know you want one, just stop farting around and do it.
It, like all other LC's will have little issues here and there which will be fixed by doing a mod here or there, putting in an ARB, a pin 7 mod, heavier springs or whatever.
Just go and order the bloody thing will ya!

I won't know until I see it. When I seen the price jump it was a big bummer. I'm not sure it's worth it over a 2007.

Actually toyota has not used aluminum for their front diff housing in any 4wd truck suv application. The aritcle is a misprint, the front housing of the new tundra is aluminum. The rear is not aluminum. Gm, ford, dodge, etc have used aluminum for their ifs diffs for over 25 years. I wouldnt say they were problem free though.

Good luck finding an '07 without Nav. You're about as likely to find one w/out Nav as you are finding a 100 series diesel in the USA !!

I've given up on a n '07.

Damn, now who's going to be the guniea pig, how are we going to learn?

Come on John,

I said this a month ago, others here already have theirs, when are you going to place the order!

We've almost decided to NOT get one. Will know this weekend. It's a lot of dough.....gotta be sure it's what I really want.

The phrase "from the Tundra" is thrown around a lot. But, it's not really "from the Tundra."

I'm pretty sure Toyota modifies all of the parts for the Land Cruiser.

 

[cruiser_guy]

I would be quite surprised if there is much cross over between the Tundra (which is a North American ONLY vehicle) and the 'Cruiser which is marketed world wide.

I can easily see a lot of crossover between the Tundra and the Sequoia though as they are both North American market only vehicles.

I couldnt agree more.

But I wouldn't compare a $63,000 Japanese designed and built Toyota to anything put out by the rolling junk makers here in America.[/QUOTE]

Better think again, this was have true a few years ago but the competition is catching up in a significant way. Nothing stays the same forever. Bet on it.

 

[twstrchasr]

I took out an '08 Tahoe Z71 4x4 this past weekend and the build quality was really good. I was really impressed with the interior. I would say every bit as good or even better than my '01 LC. I grew up on 1980's big Bronco's so I have a special place in my heart for the big USA iron. If the US auto makers make a good vehicle I will definitely buy it. I guess I'm not "brand" loyal !!

 

[uzj100]

Are you blind? I believe the new car smell got to your senses. The chevy's are much better however the interior materials are no where close to a 01 LC. I was in an 08 GMC Yukon XL the other day and I was impressed by the progress however they are still behind. The plastic is just still so plasticky. The chevy and gmc's should be about 35k max however they are approaching 50 or 55k. There are so many snowed people in this area however I believe most do not care at all.
