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

[jsoles]

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.

4 wheel drive was used on dirt and grass surface. Noise is while in 2 wheel drive while turning.

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

Hello! I have a 2022 Tahoe. Recently, when I start my car and immediately drive, when you are turning say from a street so your making a harder turn, the front wheels or somewhere in that area makes a humming noise sorta like a hmm hmm hmm. I did bring it in for a different reason and they...

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.

Hum...did they replace the pinion seal and inspect the rear diff too, or just top it off..if it wasn't the formeer, you are doomed to have it happen again, get water incursion, and ultimately have a rear diff fail...

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.

A wheel bearing possibly? Pretty early for one to fail, but a roaring sound when turning is usually a classic symptom of a bearing gone bad.
