2021 Yukon with roaring noise while turning left or right at slow speeds

jsoles said:

37000 miles, only been put into 4 wheel drive once. Just to test. There is a roaring noise while turning left or right at slow speed, (in parking lot or pulling out driveway) but clears when the Yukon is straightened up. It sounds like a hard rub but this has all been cleared. Of note, I activated the 4 wheel drive and drove about 50 yrds, put back in 2 wheel drive and the roaring is gone. If the yukon sits for more than an hour, the noise comes right back. No dealerships have heard of this issue and have no idea what to do. Thanks in advance

Never use 4wd on dry pavement and make turns the system is binding up is to why you're hearing the noise and are likely going to snap something drivetrain related. Only use on slick surfaces like snow ice dirt etc when turning.

Interesting...I have 42K and just noticed this on my 2WD Denali. Sounds like a low frequency growl when turning and then I don't hear it again once driving straight. Sounds like something is binding. Coming from the rear axle. Possibly a wheel bearing? Seems to have gotten worse the last couple of days with the colder temps here in FL.

We had the same issue when we bought our used 2wd Denali. Dealer found the pinion seal had been leaking some, topped off the fluid and the noise vanished. I would recommend anyone having that type of noise from the limited slip differential to check your fluid levels and for signs of leaking.

Did you ever find the problem? I have a 2021 GMC at4 yukon and it has just started this. I have around 44,000 miles and no one can find the source of the problem.

Humming noise when tightly turning steering wheel, only during cold start and go?
