Hello Karla,

It sounds like you may have a bearing or CV joint going out. Your vehicle will need to be jacked up and inspected. It may be more than one problem too. Its possible the dragging noise could be something between brake pads and rotor, but the grinding that comes and goes in reference to direction sounds like a bearing or joint. I would take it to a professional right away and ask for an estimate only, and then get other estimates from other shops as well. Good luck to you.

check for failed wheel bearings or loose wheel on studs. Check suspension ball joints and steering joints the problem is serious so have the front inspected by a competent mechanic

sound like a CV shaft,now you need to figure out which one LorR

The bearings are going bad in your colum

TAKE IT BACK WHERE THEY DONE THE LAST LOT OF WORK and tell them to do the complete job again as it sounds like a con job to me as a wheel aligment should last for a year a least and the grinding is in the braking system and something must still be bent ,
Its still under warranty dont pay any more..

sounds like you have a problem with one of your lines on your power steering or one of its components. the grinding noise could also be one of your pulleys that have gone bad too. check your steering assemby gear box.

I doubt it's your 4x4. Most transfer case will start turning the front driveshaft, meaning that BOTH front wheels would try to turn.

Could be a brake pad/caliper locking up on your left wheel. That'll make that wheel turn slower resulting in the veering left.

Could also be a wheel bearing. However usually you'll hear a grinding noise to go along with that. And it'll pull rather consistently in that direction rather than suddenly.

Or, what first comes to mind is that your steering box is loose, or the gear inside the steering box is stripped in one spot. Or your front tie rods could be shifting or possibly ball joints. These would cause a sudden shifting/veering.

All of these things are front end related. And also very dangerous. Take it down to any alignment shop, have them put it on a lift, and diagnose immediately.

Worse case scenerio is that a front end part breaks and sends you out of control and into someone else. Please get it checked. A diesel Suburban could do a lot of damage.

Make sure you check your power steering fluid... if it's even low, it will make a terrible noise...run it on empty too long and your can ruin your power steering pump.
