The truck tracks and drives great going straight and the looseness in the rear is during faster lane changes at highspeeds. No crabwalking from it. I can feel the rear "loose" in turns a little bit but giving the steering wheel short and quick inputs left and right staying within a single lane just gives the feeling the rear wants to steer opposite of the front tires and the truck feels a bit unstable.

I really think it is an effect of the stock truck but perhaps there is a mechanical problem making me feel this looseness. If you've ever had a flat rear tire, you will know exactly the feeling I get hile driving. It's as if the rear tires want to keep going straight or even in the opposite direction from the fronts. If I had to guess, I would say the rear tires were at 10 psi, not 32 psi, but even though the TPS light fooled me, the tires are at an acceptable pressure.

I checked the shackles based on some of the clunks / rattling I heard but will grab my creeper and do a full inspection pretty soon to see if anything is out of place or damaged.

This truck has 34k miles and I just picked it up used so the possible reasons for the issue are 1) Me not being used to how a stock titan feels or 2) something is amiss in the rear suspension from the previous owner. I've driven Tacoms and Silverados and have not had this feeling before though....

FWIW, the previous owner took the truck to the dealer complaining of rear suspension clunking but the dealer found nothing. I believe it was the tailgate being loose, but perhaps the bed rattle / clunking is related to this loose rear feel.... I doubt it, but it's possible....
