The lsd block is the weakest link that's what will wear. It's all aluminum. It will fail to stock operation. People like me don't spend too much time without checking all our fluids anyway. It's only $20 for 2 quarts of synchromesh, and I Drive 100 miles a day, mostly highway. All my fluids are at least checked weekly.
Thanks for your concern, and that could be a deal breaker for people who don't do maintenance. I'm changing oil and tranny fluid monthly.
I haven't noticed anything funny in my tranny fluid or operation, but you did spark a little interest on the subject. I just might crack the lx open and peek at the pinion and lsd.
(BIG BELLY LAUGH) the Internet said the lsd is warranted for life! That wouldn't help me if it's killing my tranny. I guess that's one more thing to remember this weekend
