It sounds like your CV (Constant Velocity) joints are worn and need to be replaced
you may have a rod knocking and you need to take it to a shop asap
mine doing the same when turning been to garage could be broke spring or strut top bearing .
Probably the end links..... Just had mine fixed and it made the world of difference. The original end links were not strong enough.
Could be, loose lug nuts on front left wheel, a damaged left front brake rotor, a bad left front hub/bearing assembly, a worn/damaged CV axle joint,
First, check the lug nuts. If that's not it, check the wheel bearings.
Check the drive axle for a broken and leaking boot or bad CV joint.
Perhaps a worn CV joint (usually more of a clicking sound when turning), but there are many components in the front end of a motor vehicle that could cause a knocking (or similar) sound, including suspension components, brakes, steering components and bearings. Worn tie rods, by the way, do not normally cause a knocking sound, but result in very loose feeling steering and noticeable drift, especially at highway speeds. A knocking sound is more likely to be an engine problem, such as pre-ignition. If you are not accustomed to diagnosing these sounds, you will best best off to see a qualified mechanic, or a friend who is more familiar with the front-end components of a motor vehicle.
is it a front wheel drive? if so the cv shaft on that side could be almost about to fall apart. or it could be the wheel bearing.
possibly hitting the front bumper
Sounds to me like a failing CV (constant velocity) joint on the axle!These will break - have it looked at real soon
A knocking noise in the front wheels can be a very serious problem. The knocking noise could be caused by bad ball joints. Bad ball joints can slip off the tie rods and cause the wheel assembly to collapse. This problem should be looked at as soon as possible.
Assuming this is an older car a knocking noise on turning could mean one of the drive shafts is worn. Other things to check - are the bolts tight on the front wheels, if a very high mileage it could be worn wheel bearings.
