2015 Tahoe/Grinding/rough noise from front of vehicle

[fatmonk8]

Hey all,

I have a 2015 Tahoe with roughly 103k miles on it.

Been having various issues, but my newest one is a metal grinding noise from what I suspect is the front right suspension. It is also able to be felt in the car, you can feel the vibrations from the grinding noise.

The CV axle on that side is freshly replaced so I'm doubting it's that. I checked the wheel bearing with the tire in the air but it felt solid enough. Suspension looks fine from just taking a look at it.

It so seems to be worse when I'm turning.

I was almost positive it was the wheel bearing but after checking it last night I'm worried it may be something worse in the drive train. Maybe transfer case or diff?

Any one dealt with this kinda noise before?

Sure sounds like a wheel bearing to me.

You may not be able to get it to wiggle. Does it make noise when you spin the wheel?

This may sound dumb, but I couldn't figure out how to spin the wheel. I put it in neutral but I assume the transfer case was still engaged.

Can you get both front wheels off the ground at the same time?

I'll try later today

sometimes when those start failing you will hear and feel it long before you can see any play at the wheel by hand.

I had the same issue, tried for 6 months to figure it out.

Ended up being the hub on driver's side.

Try some long sweeping left and right turns - like highway entrance/exit ramps, if the noise goes away or changes, it's the hub

My noise would go away on long sweeping left turns, when the weight was off the left hub - then come right back when straight

There was zero wobble when jacked up off the ground, so the "play" evidently doesn't happen until the hub is far gone

Now that it's fixed - the lack of noise is crazy, I got used to it, and at one point was going to buy new tires, I was so convinced it was a noisy tire.

Hope this helps!

Interesting, I seem to hear the noise and vibration way worse when turning. Even more so when I'm cutting the wheel hard.

My first suspicion was the hubs anyways, so if you and others are saying you don't always get the play in the hub then I might as well replace them anyways.

If you believe the right front is the culprit and when driving and turning and gets worse, if you are turning left, that loads the right front more than when traveling straight and that indicates a right front hub problem. Is the worse noise the same if you turn left AND right or more pronounced when turning EITHER left or right?

I have to think about that, I usually notice it when backing up and I cut my wheel to back out.

I'll have to double check when I drive again.

If you are feeling it at that slow of a speed and backing up and turning, I would be leaning toward the power steering/steering systems. Does it make the noise driving straight and make a slight turn left or right? Or is it at slow speeds only or tight turns, like when parking?

I feel the vibration and noise while driving straight or turning. Car doesn't seem to pull at all.

Ok, but answer ALL my questions. What speeds? Do you hear/feel the vibes and noises at parking lot speeds or road speeds or both? It would really help if you would answer all questions asked. Sometimes people tell us what they THINK we need instead of what we ask about. There is a method to our madness when we ask questions.

Thanks for the help I appreciate it.

Checked and I'm getting no noise when spinning the tire with both fronts off the ground.

All speeds

What about that new CV Axle? How are the brake pads? Are they seated and moving, does the floating caliper move a little when you tug on it?

Cv axle on driver side was just replaced, checked both and they both seem fine.

Just did a full break job a couple months back so brakes should not be an issue.

How much movement is too much with the caliper? The driver moves just ever so slightly but still feels tight.

 

[B-train]

Only a slight movement is needed ro check the brake caliper. A lot of movement would be an issue. You just want it to be able to float in a relaxed position when not needed. Binding would be bad as well.

Have you checked the front diff fluid? Or changed it in the past?

Is your truck 4wd. If so, does the TC engage and disengage properly? Does the noise get any worse if in 4-HI on grass or gravel, not pavement. Was AUTO 4wd used on a regular basis on dry pavement during its life?

Last suggestion would be to jack up all 4 wheels, put it in 4-HI, then let it idle in gear and listen for something similar to what you've experienced - inside and outside the vehicle. Sweep the steering left to right when wheels are spinning to test cv shafts for potential noise at extreme angles.

Have not checked diff fluid, have not changed it since I have owned it. (Only a couple months)

It's 4wd, it seems to engage and disengage fine with no noise. Have not put it into 4-HI a.d driven off road as I have not needed too.

It has ways been on Auto since I have owned it.

It would be pretty impossible for me.to jack the car off all 4 to be honest.
