If the squeeling noise is the power steering pump drive belt on the pump pulley - then this may indicate the steering pump is faulty / siezed perhaps due to lack of fluid or simply age / wear / mileage.

Check with the many on-line auto parts sources, such as; www.autopartswarehouse.com or www.rockauto.com for the replacement parts. For example, they (RockAuto) list the power steering pump from around $37.00 (minus the core exchange) for your vehicle.

Not sure why vehicle was in shop, may just need a new pulley belt tightened properly.

Check the Auto MD website for the 'How-To-Guide' feature and specific steps to remove and replace the power steering pump. You may also try the website; www.autozone.com for additional repair steps.
Check the many on-line parts sources;such as www.RockAuto.com, www.autopartswarehouse.com, or www.autopartsfair.com. For example, they (RockAuto) list the power steering pump from around $36.00 (with reservoir) minus the core exchange cost.
Keep in mind - it's also a good idea to replace power steering hoses - both the pressure and return - to maintain the clean and functioning steering system when replacing the steering pump. The hoses list for around; $14.00 (pressure hose) and around $11.00 for the return hose - for your vehicle - same source RockAuto or any of these other sources. You should also go ahead and replace the drive belt - if worn or in poor shape - same reason.

The only thing that,horn,airbag and cruise control have in common is the spiral cable also called clock spring.It the clock spring goes bad(has a open circuit)may cause all the above issues.Before u attempt any repairs u need to stop by at a shop to have your airbag system scanned for codes.That would be a accurate diagnosis before replacing any parts.

Hey Paul just wanted to let you know its the clockspring in your steering column good luck its a $200.00 hit

ru repacing them if so u might have to take the hub off to do this

if there inner and other bearinggs u should check or grease probbally once a year if concealed bearing such as hub they should last approx more than u will think.

A description of the sound would help, but check the front CV joints.

It's 15 years old and showing it's age . But should be fine . Might be time for a few new parts and an alignment .

Yes, the steering rack has seals / o-rings to prevent leakage. You need to purchase a new or rebuild steering rack. Try the many on-line auto parts sources, such as; www.RockAuto.com or www.autopartswarehouse.com for the replacement parts.
For example, they (Rock Auto) list the replacement steering rack for around $180.00 - or you can try to rebuild the unit you already have - get a good repair manual; such as Haynes or Chilton, and the seal / repair kit for around $22.00.

Not difficult to change the tie rod end (outer). First, raise and support the front end - suspend both front wheels off the ground. Next, remove the tie rod end cotter pin (if equipped) and rod end nut. Next, using a tie rod tool (pickle fork) and heavy hammer - remove (separate) the tie rod from the steering knuckle. Loosen the tie rod sleeve and remove the tie rod end - counting the turns. This count will help to install the new tie rod end in the same basic position.
More difficult to change the inner tie rod end.
Try the many on-line auto parts sources, such as; www.RockAuto.com or www.autopartswarehouse.com for the replacement parts.
