Just Trying to Clear up the Facts..

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!
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 (

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…
