I've noticed a metal squeak when I put the vehicle in park and the vehicle rolls a bit before stopping fully. Has anyone experienced this and know how to remedy?
I'm not sure it's that anymore, as I hear the same exact squeak when the drivetrain is loaded/unloaded at low speeds. Like if I put in reverse from drive, or I decelerate at a low speed. I am wondering if it's related to a driveline component.Find many great new & used options and get the best deals for for Cadillac Ct6 16-18 Automatic Transmission Parking Pawl Actuating Rod GM at the best online prices at eBay!

it is your parking pawl finding the next hole to lock the car in park. If you are parking on an incline set the parking brake before you put the car in park. I have even seen a car torque lock when put in park on a incline (hill) where the car had to be pushed to get the parking pawl to release.
It almost sounds like a driveshaft to me, I haven't quite had the chance to get up under there enough to look. I take it the driveshaft is not greasable?When you say metal noise, have you checked for a hung up brake pad? Besides that I'd be looking at all the rubbers. UCA, LCA, driveshaft.
It's not really a ping, I'll try to get a video of it and report backNo, it's sealed. They're not u joints either though so I don't think it'd be a metallic sound. Have you tried tightening the front cradle bolts? There was a thread a few weeks ago detailing the torque specs and such, gives a metal ping sound going from gear to gear or braking.
So I washed the car today and the rotors look all rusty afterwards, the usual. So I notice the squeak when I let off and apply the brakes very lightly. After some light braking I got on them hard a few times.. pretty sure it's the brakes. Hoping giving them some "love" will fix it.I'm not sure what he's referring to with driveshaft linkage, but if he means any of the CV joints on the driveshaft, unless you have a driveshaft shop that wants to go above and beyond for you, you'd have to buy a whole new shaft.
Id say try and get a good video of the sound.
Okay I got some videos. I hope this isn't the diff or something.A lot of times on brakes like these cleaning up the pad pins and adding some good caliper grease solves a lot of issues. Plus with the wheel off it takes about 5 mins.
It seems to go it more when there is a load/unloading of the drivetrain. I can reproduce it with the car off and moving the tire back and forth. Once it gets to the end of its "roll" before it binds up, that's when I get that creaking.Just spin every wheel one at a time, by the video that's what my money is on. When you find it just tune up the backing plate with a long flathead
I just got it a few months ago, it's an Arizona vehicle. I remember one day after washing the car, I bumped the rear corner of the bumper and a bunch of small pebbles fell out. I will check tonight if I have time.Sounds like its wheel to me as well. Do you drive down dusty roads at all? I ask because I've had the same issue on my truck before. Somehow tiny rocks/debris got in between my pads and rotors and produced a similar sound. Any scoring on your rotors?
I'd pull the wheel/s that are making the most noise, and check the pads.
