My '06 4.0 Tacoma has had an RPM relative whine for many months. Even though I am out of state, yesterday I had the power steering pump replaced by a highly recommended diesel shop. Sadly, the new pump still makes noise. The shop changed the fluid from Toyota recommended ATF to something green, per the NAPA pumps recommendation.
I am now concerned that good money was thrown after the wrong issue and have concerns about how a different fluid might affect the rack.
Have any of you had PS problems on the 06 and later Tacoma? The sound migrates around the running engine and is hard to pinpoint. IT only changes with RPM, not steering input nor effort, even at full lock.
Any help / ideas would be appreciated.
