My 08 Titan Pro4x has 70k on it and seems to be following the standard Titan problems. As much as I like to move on to a different truck, new ones are ridiculously expensive which in turn makes used expensive. One the issues that I have with this truck is the diff locker. I live on a hill so in the winter when it get a little slick I have to put it in 4wd to pull out. I did not have this problem with my Sierra. I have to pull the axle to fix e-brake detonation damage. So is it worth going the extra mile and changing to a tru trac? Not sure if it's worth it. Or should I just bite the bullet and move on?
