My X series jag is making a deep whining like noise especially when I move the the steering wheel only slightly left...any ideas. Thanks

sounds like you have a bad wheel bearing, does sound change going around curves ?

Need more info but sounds like power steering gearbox or cv joints. What happens when you turn all the way left or right? Is it worst or better and what do the noises sound like? Whining or grinding?

Whining sounds when turning the steering wheel usually indicates a bad power steering pump.

Most likely a wheel bearing, Take it for a drive, When you hear the noise move the steering wheel slightly right then left and listen for a pitch change in the whine, What ever way the pitch changes, Say you turn left and it changes? Its the left bearing and same for the right.

normally, the only part of your automatic transmission that will make a whining noise is the pump. it usually whines when iether the fluid is low or more commonly when the transmission oil filter is getting plugged up.

the power steering pump will also make a whining noise too.

turn the wheel all the way to the right and hold steady pressure against the stop. this puts maximum force on the power steering pump and, if the power steering pump is the one making the whine, it will change the sound of it. (usually louder).

if the trans pump is making the whine noise, it should sound different in neutral compared to drive. this test will really only work if it make the noise without the vehicle moving. if it wont do it at idle hold the rpms at 2000 or so.

if you decide the noise is coming from the transmission, and the transmission filter has not been replaced (assuming you installed a used transmission), replace the filter by removing the oil pan.



oh and also, if it is the power steering pump you should be able to make it make the whining noise while the vehicle is stationary. if it wont make noise unless its moving its not the power steering pump.

Take it in and get it aligned, explain to them what happened and have them loo it over while its up on the lift, just to make sure there isnt anything bent!

yes you can, make sure fluid in power steering is full. jack up car and move steering from left to right, til it hits wheel stops. keep checking fluid level. when bleeding air from system, raise idle to about 1500 rpms. then turn wheel left to right. after done recheck fluid level.

my 325i makes a whining type noise when driving (not all the time), but stops when I apply my brakes. Any idea what this is?

First thing is to check the level of the power steering fluid. If you're low, add enough to bring it back into range. If not, remove the cap and jack the front end off the ground (both wheels). With the cap off, turn the wheel lock to lock, back and forth, several times, to see if any air bubbles need to be bled out (this will bleed them). Then check the fluid level again and top it off as needed.

If neither of these helps, have the steering system checked by a shop - you may have a problem with the steering shaft, the tie rods, or the rack itself.

There could be numerous problems going wrong. Your car is rear wheel drive so it could very well be a bad wheel bearing. If it is extremely loose it can cause a shake in your steering wheel. You may want to check on the condition of your tires and rims especially the left front. A bad tire can cause a shake and pull. If you know how to use your car jack you can try jacking the vehicle up, and put both hands on your front wheel and move it manually to see if there is looseness. Most shops only charge about 1/2 hour to shake down the front end. BMW parts are expensive so be prepared!
