I have over 175,000 miles on my original TREs on my pickup which has a front locker and has been wheeled lots. I have gone through 3 or 4 idler arms but never had an issue with TREs.

That said, I have a complete set of Moog TREs that have been sitting around for over two years waiting to go on. I always thought I would SAS my daily driver but now that I have built my FJ40 up that is doubtful.

I guess it is time to replace them now before they fail at the wrong time. <img src="/forums/images/graemlins/zombie.gif" alt="" />

Bottom line, I don't see any compelling reason to go with modified TREs on your IFS unless you are having bending/breaking issues.
