It usually indicates warn tie rod ends. My 98 was doing that same thing. They can't be greased, only replaced. My 2000 squeaked when I turned. The Power Steering fluid had become as thick as glue. Cost me $300 to clean it out. Apparently they produce a lot of heat and cook the stuff. I now change it once a year. BTW-Transmission Fluid gets thick faster on these too. The squeak you describe could be another expression of the same issue addressed here http://www.cartrackers.com/Forums/live/fordwindstar/1892.html where the upper strut mount gets a spacer per a Ford recall, or just a complete replacement (due to wear). Enjoy, Ben you can make a small hole with a screw drive pick and put some tri flow i had the same problem and since then stop... My '98 had the same issue on the right front wheel (passenger) when turning to the left. There is a flat plastic panel attached to the suspension rail. It bends down toward the wheel with use...probably due to heat. when the panel touches the wheel during a left turn, then you get an ungodly noise coming from that side which gives you the impression there is a steering issue. There is no steering issue...just that plastic panel. take it off and throw it away or replace it with a new straignt one. or just heat bend it back into shape with a torch. I did this last year and it was fine for a year and am doing it again today.
ball joints or tie rods
ball joints upper and lower control arm
Most likely the front squeaking while turning is a brake issue. If this is the case and it is left uncorrected, you could be looking at a very expensive brake job.
A bad bearing can cause can the front end of car to make a squeaking noise when turning steering wheel either direction. It can also be caused by bad suspension.
cos its a renault
Most likely it is low power steering fluid. Check fluid and see if noise goes away.
it´s possible that a bad hydraulic lifter is working dry.
no it makes cranky noises
could be the power steering belt, axle going bad. power steering pump it self could also be bad.
ball joint or tierod end
Its Your CV Joint Or Your Wheel Bearing ........... if it is your cv joint you will hear the knocking or clicking sound especially whilst turning corners.xxxx
