Do you have to have your power steering flushed--have 100000 miles
Some say, yes, others no. Save some coin and do it yourself by removing what you can out of the reservoir with a turkey baster(if the opening is to small I use an old clean soap dispenser pump and a large cup to catch it in), add the correct fluid as outlined in your owners manual. Some cars use ATF, some PS fluid. Fill and start the car, in park, turn the steering wheel back and forth, lock to lock a few times to get the air out. Repeat till the fluid looks like new.
My scheduled maintenance schedule doesn't mention power steering nor brake fluid changes as being part of maintenance ; and yet, some people highly recommend it. If your vehicle owner's manual says you should do it then you should. otherwise; it's up to you which camp you are in. can't hurt to do it
BTW: I have my original PS fluid in my 26 year old Mustang. Just added a bit over the years from leaking.
