06 Access Cab V6 4wd. It continues to be very reliable but has some annoyances.
- Cold start engine rattle. This is not the "normal" ticking sound, it's much louder and goes away within a few minutes of driving. Can't pin point it with my stethescope, it's been an on going problem for over 40,000km, has not gotten any worse. Piston slap is my best guess.
- Exhaust manifold "flutter" noise at certain RPM's since I have owned the truck, I was well past the warranty before I realized there was a TSB to upgrade to the 07+ tubular style manifolds.
- No grease zerk on the drive shaft slip yoke, next time I have to pull the drive shaft to grease the splines im just going to add my own zerk.
