chirping @ 50+mph?


Asked by Sep 01, 2010 at 03:40 PM about the 2009 Mercury Grand Marquis LS

Question type: Maintenance & Repair

09 with 20K mis.  bought mid July, had been in minor front end colission.  repair was great.  
3 weeks ago a chirp began.  replaced idler brg and chirp stopped.  chirp returned Sat. while doing 65-70 on turnpike.  I replaced tensioner brg which seemed a little loose but chirp's still there.  in fact chirp starts when it warms up and is going 45 or faster.  
I cleaned the belt with a fiber pad and the pulleys with a wire brush.  blew everything off real good.  still chirping.  belt looks good, no cracks or shine.  the chirp seems to come and go without a link to anything besides warmed up and some speed.  not at idle or revved up in N.
there is some end play on the pwer steering pump shaft, not real bad but noticeable. thanks for reading
