Steering veers to the left?

1. Turn left directly from the bike lane.
2. Keeping a weather eye on traffic, move into the left-hand lane and turn from there.
3. Veer right onto the sidewalk (avoiding buses, obviously); wait for the pedestrian light to cross

Wheel bearing brother, does the noise go away when you veer to the left or right? Quiet veering right?( it's the TT wheel bearing), quiet veering left, ( left bearing is culprit

When you turn the wheel to the right, the vehicle (when in motion) will veer to the right. Conversely, when you turn the wheel to the left, the vehicle (again, when in motion) will veer to the left.
The turning of the steering wheel is made easier by the advent of the electric power steering. its precursor, hydraulic steering assist, performed the same task in a different manner.
Is that what you were asking? NO? SHOCKING!
(PLEASE ASK AN ACTUAL QUESTION THAT CAN BE ANSWERED.)

A failed c.v axle could have cause exactly what you are explaining... it actually almost the only thing

check lower track control arm bushes

i would check the power steering gearbox. sound over tightened or exessively worn.

possibly a wheel bearing or tyre noise from badly worn tyres
while driving in a straight line and noise is present change lanes or shimmy car left and right if noise gets worse or better wheel bearing problem
also if noise gets worse in normal town driving speed and gets less at higher freeway speeds check your wheel bearings

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.

do the tires were right it could be out of alinment or only 1 front tire is pulling it could be in the trans
