One Click Forward, One Click Back?

[turbocruiser]

Hi folks, was wondering about some strange clicking I'm getting. It only happens once each and every time I switch from forward to reverse or vice versa from reverse to forward when I hit the brakes. IOW put the rig in reverse and start backing up and hit the brakes to stop and I get one quick soft sounding "click". Then, put the rig in drive, do the same, get the same. I'm wondering what this might be. It almost sounds like the locker sounds when locking in but of course the locker is unlocked. BTW the lockers work without problem when I want em to. The only obvious hint I have is that I recently changed my rear brake pads and also removed the rotors to clean them. Is it possible that one of the brake pads is shifting slightly forward and back when I hit the brakes? Any thoughts? Thanks.

It's the front driveshaft splines, take it a part clean it good and regrease it with some good quality grease.

Yes, the pads are not press fit, when you change direction the pads will move a few thousands of and inch until they touch the other side of the caliper.

If you want to confirm it try shifting R then D while holding the truck firmly in place with the brake, if the noise happens it's in the drivetrain or loose caliper, rotor. Now let up on the brake just enough to allow the truck to move in gear with a good amount of brake drag, shift N when the truck stops shift the other direction still holding the same brake drag, if the sound changes with brake drag it's probably the pads. You may want to have someone walk around the truck and listen to each one, if there all close to the same and minor it's probably not a problem, if one is noisier you may want to inspect it. Silicone grease on the pad to caliper contact points will somewhat mute the pad click.

Like Tools said, my money is on the brake pads. Has this same problem and that is what fixed it.
