2004 6.0 NV4500 Tahoe

That keeps bouncing around in my head since it's the only thing I haven't replaced. I visually inspected them and I don't have any of the common symptoms like header clearance issues but I have not watched the engine while someone revs it. That will probably be tonight's investigative work.

That's a good idea. Any other bad noises during takeoff or cruising down the road?

Nothing that stands out no, the trans always makes a little noise but nothing crazy and every NV I've driven makes the same little bit. I'm gonna check the motor mounts tonight, I really don't want to replace them not sure if it's possible without unbolting the trans. I'll likely go with OEM replacements if they are shot, The atomic mounts are awesome but they suck to install, everything is so tight.

The OEM mounts in the NBS rarely go bad. They’re not fluid-filled like the NNBS.

That's what I've heard and I've never seen a set go bad but close to 50k with a cam/headers and they are probably 2004 originals. IDK I guess I'll find out tonight.

The fluid filled ones are definitely worse

Yeah, failure rate ^^^

I would look at something in the rear suspension. Maybe something loose or a bad bushing allowing the axle to shift cause the change of direction???

Is that because people don't check their motor mount fluid?

Last week, when I put the new shocks on I grabbed everything and gave it the ole Wiggle-wiggle. Nothing seemed to move which doesn't rule out worn components but since they are all new I find it less likely.

I thought that was always a part of maintenance. You're supposed to check your muffler bearings, blinker fluid, and motor mount fluid at the same time, along with your air filter battery and radiator hammer tap test.

I don't do the radiator tap test in winter because I emptied the coolant to help it warm up faster.
