Grinding noise 06 ltd

[wlrunner]

Hi everyone,
Newbie here and need some help to identify this grinding noise. I have an 06 LTD and its only 300 miles on it. I hear a"GERRRR...." coming from the rear wheels area(brakes or suspension?) whenever I shift from P to D or D to R. The noise is similar when you first apply the brakes after a heavy rain. Thanks in advance.

The ABS system will run a self-test the first 10 or 20 seconds after you start the engine and drive.

If the noise is happening after that (all the time), maybe the auto-level rear is making noise?

The noise is always there unless I press the brake really hard to stop the excess movement when shifting. If it's the auto-level,is it normal? Any part I can lube to stop the noise? Anybody else has the same noise? Thanks.

You are supposed to come to a stop to shift from D to R or R to D.

If you shift while it is still going in the first dorection then your dash lights will come on and the trans will make a grinding/clicking sound.

That sound is the T4R saying "If you keep doing this you are going to break something"

Actually it is the same sound that you hear when you allow the truck to slip backwards after coming to a stop on a hill, taking your foot off the brake and not giving it any gas.
