It's your upper steering shaft. Either take it off and grease or replace it.
Could be many things, ball joints usually make clunking noises (usually one when turning and one when turning the wheel from turning), cv joints usually make a clicking noise and vibrate under load. Have it checked out, les schwab will do it for free (check it).
Possibly a worn engine and/or gearbox mounting or exhaust mounting
it is the door alarm
The knocking noise could be one of several things. The wheel bearing, a worn steering or suspension part, or road debris could be causing the noise.
engine problems not trans.
The power steering pump could be on it's way out.
It can if it is really bad. Try not to drive it and have someone who is mechanically inclined check it out, it could be a number of things.
I had the same chirping noise. My chriping was the belt and/or the power steering pump. I replaced both. no noise now. I would first replace the belt, then the pump
I posted this earlier. weather the van is in gear or out of gear, driving or braking, as soon as it pass 50 mph it starts to make clunking noises from under the engine. not particular to one particular place but mostly from under the passenger footwell, then under the engine itself and sometimes a quieter noise from under the driver seat area. the noises sound like a chipping of metal or a quick and short grinding noise.
Check the strut or the C-V (Constant Velocity) joint if the noise is in the front. Stablizer link or ball joint would also be points of concern. possibly check the outer tie rods
Vibrations and clunking noise are both signs of bad motor mounts. If the clunking is getting worse than mounts should be changed to avoid any serious damaged to major engine components.
On a front wheel drive car I would suspect bad CV joints. On a rear wheel drive car I would suspect a bad universal joint. Have a mechanic look at it right away.
