mine doing the same when turning been to garage could be broke spring or strut top bearing .
u knocking on it
could be your steering is messed up for the turning. but for the transmission you could have blown piston
Could be the CV joint is dry or has failed.
No
The thing that could cause a knocking noise in your car is the same thing that could cause it in all cars A rod that or a flat lifter. it all really depends on where the knock is if its higher and to the back of the motor, it could be a motor mount
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.
Having a bad rod bearing could cause a truck to make a loud knocking noise and shake when driving at high speeds. The engine having a coolant leak or an engine timing problem could also cause the knocking noise.
The outer CV joint could be on its way out, check to see if the rubber gaiter has gone - is cracked or perished as this lets water in and causes more wear. Should cost £80 - to £100 to fix.
it could be the center support bearing in your driveshaft
A forgotten tool maybe ? Or a stone .
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.
Could be a bad CV joint or bad wheel bearing C.V. Joints need replacing
