Makes sense that it would. with the CDL engaged, the rotational force of the entire front end of the drive train is now tied into the parking brake so there is more force to counteract the grabbing force of the hand brake dragging. I'd be surprised if it was the handbrake but certainly worth a check. Pretty easy test, i'd just jack one rear wheel up and spin it with my hand and observe the rear shaft and drum (CDL disengaged). If it's spins freely.. keep looking.

It was making the horrendous back and forth clang clang this morning as I was slowing to a stop. Mind you, it does not do this if I quickly slow to a stop, only when there is no torque on drivetrain. I When it started doing it I pulled on parking brake and heard and felt what I think you guys are referring to. My issue seems to be more coming from the front end. Can anyone school me on A frame bushings ball joints, etc?

Thanks much!

could be bad panhard and or radius arm to axle bushes.

i would just adjust the parking brake out almost all the way just to be sure first.

The reality is that you need to get under there and start looking for things that are wrong. Have you checked the parking brake adjustment?

other than my experiment with pulling on the brake, no. My problem is I'm pretty sure I wouldn't know if something was wrong unless a sticky note and an arrow were in place.

I just don't know what to look for...or how to adjust the brake for that matter...

Willing to get dirty tho.....

Read the workshop manual. It is all clearly laid out.

On the transfer case side of the parking brake drum, there is a square adjustment screw.

On a flat surface, with wheels chocked, disengage the parking brake and loosen the square adjustment screw. With each half-turn of the screw, test the engagement of the parking brake. It should become looser and looser to the point where it no longer holds the vehicle.

I would try driving the vehicle with the parking brake set to where it no longer holds the vehicle and see how that affects the noise.

-----

i would also double-check the tightness of the bolts holding the front brake calipers.
