80 vs LR axles

Hi Reno
Ok I have to ask as I usually do when I need to get answers.
So it would seem there are a hell of a lot of veriables concerned when thinking of the strong and of course weak points of a vehicle.
So is there any way of knowing how much extra strain these MTs put on the axels.
Is this extra strain delivered regardless of the terrain on which they travel(ie) is the strain the same weather you use them on or off road.
Alao is there a way to calculate the forces or strains going from the various size of tyres like from a 31 to a 33 to a 35 and what you can expect will or can go.
On the LCs you say that the weak point is the CVs but could that not be a good thing insteaad of the breaking point being somewhere else that would be more expensive both in parts and time.
It is possible to get stronger CVs but then the strain goes deeper inside the axel and drivetrain.
Also to know what tyres cause what damage you would really need to have tow indentical vehicles with new parts fitted in the axels to do the same driving for a long time and then you would know or not.
I think you can have no problems with your vehicle and then fit bigger tyres and have a problem, but is the problem the tyres or the wear and tear prior to the bigger tyres being fitted the culprit.
What did you friend advice you to do in mods to safe guard your LC from damage.

No, but we have BIRFIELD joints that break in TLCs. Front axle joints never seem to break in LRs.
Any vehicle can be broken. It's just a question of how hard you push it, how much torque your rig generates, how much your rig weighs, how much you air down, and how tall and knobbly your tires are. Simex/BlackStar//Fedima brands have some very aggressive 33"s and 35"s that can put axles to the test. I have a buddy with a Patrol that had suffered no breakages until he bolted on 32" Fedima Siroccos. Another guy with a Sammy used to break every other outing until he took off his 33" Simex and went to 31" Fedimas.
My buddy owns an LR specialist shop near Switzerland that builds up expensive LRs for fanatical clients. He also competes himself (took 13th in last Portugal Rain Forest event). So I'm pretty well informed as to what breaks on LRs. He's also the one who spotted the hairline cracks in my 80's LF frame rail where the steering box mounts. He knows Toyotas a fair bit too. Following his advice on what to modify on my V8, I have broken zero, as in nothing. So far. But then I have only 160hp and about half the torque of our HDTs, and I only run 33"s. 35"s would add more stress.
If I were to decide to build up my 80 to do the type of hardcore 'wheeling that I do with the Range, then surely I would have to undertake some realibility mods to my drive train. Sure, an 80 probably already has a stronger set of axles than an LR. Look at the weight diff, the 170hp, the factory locking diff option, and the enormous torque output. But when you plan to increase the load on any given part, it's better to anticipate trouble than to have it anticipate you. That's my motto anyway.
One word on locking diffs, then I'll stop. Keep in mind that adding a locking diff to your rig effectively *doubles* the maximum torque load that each axle shaft can see. That's why I added HD rear axle shafts and hubs. Because our 80s already have the locking diff options, the Toyota engineers sized the axle shafts accordingly so they won't break when we lock our diffs.

John,
I wouldn't worry about issues with the CVs for the sort of driving you
are likely to be doing in the sort term.
When you get your 80 kitted out with 35" simexes, a six inch lift and
then go off rock crawling then you might start to encounter problems.
For normal mud plugging or overlanding it isn't an issue unless you are
driving really stupidly or the components are excessively worn already.
And yes, it is possible to get stronger than stock CVs from a company
in the US.

Reno, Reno, calm down. No-one's saying LRs are crap. Just because many
listers live in the UK, most of us either had or still have a
Landrover, Disco or RR. Therefore we seem to be pretty well clued up
about LR's strong and weak points. And because many of us have
realised there are more weak than strong points, we migrated to
toyotas. BTW, I've not heard of anyone who's sold a landcriser to buy
a landrover because he was fed up with all those mechanical problems.
On my Disco I used to have a sticker that never failed to piss off LR
mechanics, and it's been quite a few of them needed to keep it going:
"All parts falling off this vehicle are genuine examples of fine
British engineering"

In Norway TLC is number ONE for sale many years.
The people buy it because they know the the favorite:''Toyota-quality
ALL the way!!!!!!''
Though it is very expensive compare to other 4X4 you have to wait to
be delivered to you!
Cheers Toyota fans!!!!

Hi Lubomir,
You will find the UK is one of the few places in the world where they
are No. 1, Landcruisers have outsold LRs 20 times world wide.
