The LT230 is one of a few things Rover got right, this thread is lame.
Dear god please lock this thread
What, before I come back? Rnphoto, I think your a nice guy so take this question in the right perspective but, did Bill from GBR explain how he figured the diffs are only good for 40 minutes? Not questioning you or wanting to endanger our cease fire just wanting to understand the statement.

Interesting. I guess that explains the trickle of diff failures that come across the forums but, it doesnt seem as prevalent as the front diff failures on the 100 series land cruisers when used off road. I guess land rover got it halfway right.He explained it as "a calculation of wear on the spider gear". You'd have to talk to him to get the full answer. Listening to that guy is like a customer service rep understanding what a aircraft engineer is saying. He said 40 minutes of fully engaged TC just spinning a wheel. Could be like 400 bursts of 6 second spins, or 40 minutes all at once. He explained that LR beefed up the diffs for TC enabled Rovers, but that they are still not strong enough(as seen in my DII's blown front diff).

The center shaft/pin in the stock diff carrier is the weak spot. Over use of the TC and bouncing the tires can cause a great deal of stress on this center shaft, causing the carrier to fail. I blew up the carrier in the rear diff of my old DII not even bouncing (see below) it around on the rocks. I am very light on the throttle as well, this just a plain weak point of the Rover diffs.

I haven't heard specifically about this 40 minute mark but I can almost gaurintee this is the part of the differential Bill is refering to. On trail rides in Florida the TC activated quite often in the sand/mud so perhaps this extended time (adding time towards the mentioned 40 minute mark) using the TC led to failure when not a great deal of stress was put on the diff. I would highly suggest looking over GBR's website as they have a great amount of information on Rover diffs.
