Half shafts?
A single knocking noise when braking or turning can be caused by a faulty axle. The cost of replacement is usually around 1,000 dollars.
Normally caused by worn steering or suspension components.
You possibly have warped brake rotors on the front. Or Bad Wheel Bearings.
Wheel hubs or bearings or could be the CV shafts.
replace rotors, sounds like they are warped. if you can feel the pulsation in brake pedal they could be warped..
what would cause a rubbing noise on drivers side front wheel especially when braking ( I replaced rotor and wheel bearings are good) ?
Transmissions, gears, bearings, drive lines. Is there a particular thought you wanted an answer too. About the only time friction is desired, is during braking.
you might want to check your left side wheel bearings
The problem ended up being defective spark plug wires. sounds like rod bearings. It couldn't be the rod bearings, because the engine would run for a few miles and then quit. Rod bearings tend to go quickly.
You should have someone pull off the hubs and check your bearings to see if they need to be replaced or just repacked
Check the entire front end. Wheel bearings, ball joints and tie rod ends can all wear and call this problem.
when there is excessive movement in them, rubber gaitors are split or rotten and rust in the ball socket, steering wander, uneven tyre wear, steering knocking, especially pronounced under braking
