They could have just supplied 1 new axle

MD literature stated that new axles were needed as having a locker increased stresses on the axles.

Indeed they could but if you're going to the trouble of making one you may aswell make the simpler one too, and then add it as a feature of your product....

I agree there are circumstances that would make a locked car more likely to break something but there are probably more situations where it would stop or reduce the risk of things breaking....

I think if you are a controlled driver, there is less chance of breaking something with a locked vehicle because you need so much less effort to get to the same place as open diff vehicles.

I doubt there would be many people who have had a locker and not want one or two in their next vehicle.

Don't get me wrong, I wouldn't be without lockers.

However, I know plenty of people who only started breaking things after fitting them. E.g. Aquarangie (IRC) drove for ages with 33's and standard RRC 10-spline rear axles. He installed a rear ARB with the same axles and tyres and snapped BOTH rear halfshafts on his first trip out.

Note - same driver, same driving style, same vehicle.
