I do not feel that this is a lifter tick because at idle the truck sounds OK. I noticed the ticking noise when I was driving on hwy and drove next to a concrete barrier for the noise to reflect off of while I had windows down. The ticking is dependent on my speed and I have half a mind to consider the Torque Converter. I put this automatic truck into neutral while at speed and the ticking may have slowed down but it absolutely did not immediately go away, but othewise I have very bad hearing and live alone. It seems to be present with o/d on and off and most noteworthy in 3rd and 4th but could be present in all gears. 2 months ago I had trans rebuilt with new TC and the trans shop was a POS but otherwise I am wondering if this could be a rocker or injector related noise? exhaust leak?
I am desperate for advice bc recently my parent died and so a relative used some loopholes to more-or-less steal alot of my property from me leaving me with only my horse trailer truck as my daily driver. I then had to rebuild my trans and now this. . .

Could be a rock stuck in a tire, or maybe something else stuck in the tread.

Possible exhaust leak.

Could also be a u-joint

Maybe could have been but checked.

Haven’t thought of that one but I can faintly hear it while idling.

Is it possible it could be a problem while the IPR or the high pressure oil lines? I bought the truck about 6 years ago and that’s one of the few thing I haven’t replaced. Maybe not getting enough oil pressure to the back injectors? I took a 1:45 trip yesterday mostly running 75 mph. Ran great but the ticking was still there. This morning I start it up to run a few errands and it sounded much better but after a few miles the noise came back. 🤷‍♂️

Doubtful it's anything to do with the IPR or HP oil system. Possibly fuel pressure is a bit low. The sweet spot for fuel pressure is supposed to be around 65 psi. That's where I run my regulated return system.

Are you having the same issues as the OP? He hasn't been back since last May.
