I have a 2001 Jeep Grand Cherokee, for the last few weeks the steering has been making a tremendous 'knocking' noise with a slight vibration through the steering wheel, all upon turning left, generally at slow speeds, corners, manouvres etc. It also restricts the 'lock' amount as well. This doesn't always happen though which also brings into play the intermitent problems scenario. There are no such problems to the right ?
My superb mechanic is a bit stumped, can you help ?
Many thanks,

My 2001 jeep was doing that recently. Have you checked the steering fluid. If low need to fill, then turn on car and turn the steering wheel to get fluid going through lines. Also check the input and output lines make sure they don't have a hole or crack. In which my input line had a hole and was able to replace, refill fluid working just fine.
Check the steering rack.
Check the power steering pump.
Check the Tye rods.
And your left Struts.
That will do it.
Rate this too.
Roger we have same problem and have paid to have fixed but still there. What has worked for you

Hi,
It's difficult to tell as I am slightly deaf !! I don't think there is any 'whirring' noise though, also since I posted this the reduced steering lock is getting worse, any ideas ??
Many thanks,
Rog
sounds like a loose wheel or more likey a bad wheel bearing. does it make a louder "whirring" noise with increased speed?
