Hey, a mod'ed Discovery can be pretty cool, even if it isn't an old Series ( i love the old series rovers)
Hopefully the LC is on the left, the one on the right looks like hell
either way the one that came out of an 80 did not have lockers, locking 80's diffs have 4 small gears instead of two

yea it is a cruiser front diff from some truck that was not maintained very well. I have seen a couple, not quite as bad as this one though. Lucky owner if nothing was screwed up. robbie

Yup, the right one is from a 24 splined LR (RRC>93, D90, D1, etc) and has broken spiders from Moab last year. This particular one belongs to a D90. And another yup, the 80 carrier came with no factory lockers.
It's crazy that two pretty similar weighing vehicles has such startling drivetrain differences!

I bought my '91 at 173K -- Rick and I did the front axle at 195K, less than a year after its purchase --
-- with a little kerosene and brushing, this diff cleaned up nicely and is now bathed by mobil-1 on a daily basis --

Just Trying to Clear up the Facts..
Okay, No trying to start any arguments, just clear up facts. I will not dispute that the Land Cruiser is a more reliable vehicle, with better build quality (even being the Land Rover Nut that I am). But that is just not a fair statement. The Defender 90’s size/weight/GVWR are not in the same class as the Cruiser, nor are they intended to be. The more realistic comparison in size/weight/load capacity is the Defender 110, which uses a larger rear axle (essentially a Dana 60) and differential, just as the Cruiser does. I believe the front axle differential is similar in size to the Land Rover differentials though, isn’t it? Another reason Land Rover Differentials are not as strong, they are spiral bevel designs, not hypoid designs. This leaves the ring and pinions torque/load handling capability far below a similar sized hypoid design because there is less contact area between the teeth of the spiral bevel design (You’ll notice the pinion of a land rover third member is centered, where he Toyota third member’s pinion is offset because of the hypoid design). The hot (But expensive) set-up in the Land Rover world is a conversion to a hypoid gear design using a Toyota third member housing, Differential and ring & pinion gears by a company from Australia called Jack-MacNamara Differentials (http://www.mcnamaradiffs.com.au/).
Land Rover Defender 90: 3,650 lbs Curb Weight/ 6,093 lbs GVWR
Land Rover Defender 110: 4,840 lbs Curb Weight/ 6,504 lbs GVWR
80 Series Land Cruiser: 4,834 lbs Curb Weight/ 6,470 lbs GWVR
Here is picture of a D110 Differential on the right, and a D90 Differential on the left (both stronger 4 spider closed carrier Differentials). Much more like the Cruiser to D90 differential comparison above, no?
I hope no one jumps all over me, I’m just trying to set the record straight here. I love Land Rovers for their design and off-road capability, hate them for their build quality, reliability, customer service, etc…. I Hope to replace my Discovery with an 80 Series Cruiser soon, I hope when I do my enthusiasm for Land Rovers doesn’t brand me…

No jumping, good info and i appreciate it. I almost bought a rover before the cruiser, i've always liked them. 
:whoops:
:whoops:
Same here, I'd still love a nice 110! Maybe when I get that extra $60K burning a hole in my pocket....
Love the look of the vehicles, and the Defenders aren't as prone to problems due to their relative simplicity.
For all around trouble free use; I'll keep my 80 though.

Alia also has (had?) a built Range Rover, so he's not necessarily trashing the marque here.

My viewpoint, as a former Discovery owner, is that I will never own one again.
Love the design, hate the quality and durability.

Ditto here. Makes me think that the Toy engineers basically reverse engineered a LR and noted where the improvements should be made
I sold my RR along with every piece of spare parts I could find all over my house except the engine! She left my house with the cargo area full of stuff. BTW, anyone wants to buy a built 4.6 alum long block LR engine? It's light weight and is perfect for a tube/rock crawler project. I spent lots of dough on the heads and the cam grind is for low end torque starting at 1200 rpm.
Interesting discussion, and suprisingly unbiased.
I recently sold my 2001 Land Rover Discovery II because of major reliability problems. Land Rover is a great example of a really good idea, poorly executed. IMO, there are few vehicles that capture the "image" of adventure and expeditions better than a D110 or properly outfitted Discovery. However, after having over 20 major repairs in less than 35,000 miles, it was just too much. The Disco was very capable and had a great payload and driving charactoristics, but if it doesnt get you home, what is the value of all that?
Here is some more info on my Discovery: http://www.expeditionswest.com/vehicles/ewvehicles/Land_Rover_Discovery/index.html
This was a trail run to FR42 that I led with a few Discovery's and even your very own John Shott's with his UZJ100 TLC (lots of video and pics): http://www.expeditionswest.com/adventures/2003/FR42_2003/index.html
I frequently drive thousands of miles into Mexico and cannot afford a compromise to reliability. That is why I drive a Toyota now...
