4wd low noise

When I use low 4wd, it works fine but when I stop and shift straight to park it makes some sort of loud clicking/grinding noise (it sounds bad) but if I shift to neutral first and stop there for a couple seconds, then shift to park it doesn't make any noise. Any idea what is causing this?

That's odd it almost sounds like the driveline is still turning when you stop. It should not do that. Is this a manual tcase or electric. If electric maybe it's not shifting correctly.

I was going to say that earlier, thats exactly what it sounds like. It is electric. However, it doesn't do it when in 4 Hi.

And I don't know if the noise is coming from the transfer case or the transmission.

That is what it sounds like. Almost like the drum is still spinning and the parking pawl is skipping over the slots (like shifting to park while still moving)

Given the high strain on the drivetrain due to 4-low, it's a good idea to shift to neutral before going to park anyways. I've done it with nearly all the automatics I've owned. This takes all the pressure off the drivetrain before shifting. I also pause in neutral anytime going from drive to reverse and visa-versa.

Going back years, every one of my trucks, including different brands, has made the noise you described. Even though I wondered what is was, I have written it off as normal.

Thanks guys. I don't think I will worry about it then. I think I will just make sure I shift to neutral first before shifting to park or reverse, since when I do that it seems to work perfectly fine. Thanks again for the insight.
