Hello all. I just bought a 2004 king cab se 4wd with 95000 original miles. Drives great, no noise or leaks, 4wd works fine. I would like to know if diff failure is iminent, or do some trucks never have those problems? As far as i can tell, this was a grocery getter and saw very little hard use. Carfax has a ton of scheduled maintenance and some minor stuff but no major service. Is it possible to prevent diff failure front or rear? Yes i searched and most threads are complaints of the failure and or service actions taken. I would like to prevent it. On a toyota the prevention is to replace a needle bearing with a bushing. Any such fix for a titan that is still in good shape? Thanks for any advice.
