Squeak in the Rear End when Turning

1096 Views 13 Replies 5 Participants Last post by  xydadx3
My '19 Ascent Touring has developed a squeak in the rear end when turning a corner. Initially, it only happened when turning right; now it does it which ever way you turn.

I would have immediately thought it was a bad shock or something in the suspension on one of my older American cars, but I really have no idea what is down under there on the Ascent.

Any ideas what to look for? Service will be looking at it shortly.

Many thanks.

Well I was going to hold off on posting until I had investigated more, but my 2019 Premium has the exact same symptom.

Interesting that @Robert.Mauro brought up the rear brake pads because mine were changed recently. Though the sound doesn't appear to have to do with the brakes I'm considering it a possible factor due to when I first noticed the noise. I'll check my spare tire mount soon too but its doubtful; its not consistent enough for that.

My first thought was suspension noise from struts, mounts, ball joints, etc. However, I don't think I've ever heard the noise while driving straight no matter how many bumps I go over. I've noticed it most when turning right. My wife actually thought I was tapping on my horn at first. I realize the forces on the suspension are different when turning vs straight so suspension isn't ruled out, but could that indicate something going on with the rear diff?

My next step is to sit in the 3rd row while someone else drives and try to locate the noise from there.

@Foveator lets team up and figure this out! Let me know what they find at your service visit. I'm holding off on a visit for now.

@Foveator if that's indeed the same problem with mine, and I'll bring up that TSB when I take it in, I owe you a beer!

Are you still under warranty or gold plus plan or whatever its called after 36k mi?

Just to make sure we鈥檙e on the same page does this sound a little like the noise you鈥檙e hearing? Ignore the diesel-like sound, that鈥檚 a toddler鈥檚 seat and annoys me so I drown it out with music usually, and the rustling of plastic bags that were in my trunk. The noise sounds a little different on video than in person but it鈥檚 there. This was recorded going about 35 moving the wheel back and forth quickly.

I wanted to take a moment and update this thread since I previously posted here....

I humbly admit I'm an idiot sometimes. Sometimes the simplest solution is the right one and that was the case this time. I still haven't been to the dealer but I can cross this one off the list.

Upon opening my trunk and putting the lug wrench on the spare tire hoist I was able to tighten it a little. It might be worth noting there is a click when the hoist is fully tightened (I had to RTFM to confirm this). I felt/heard the click a couple times then stopped tightening just before I felt like I was about to get the click again.

I haven't heard the noise since.
