Question about Mercury Grand Marquis
SOURCE: high pitch sound
Front wheel bearings. We have a 2004 Limited and ended up getting both replaced (at different times) paid for by Ford. We only had 40,000 km on the vehicle at the time and had to fight Ford to cover the cost. The did come through in the end.

No Adjustments. The shocks are just too Soft. Replace them with the Originals From Factory and they will be better. They get softer the longer they are used.

you might need a stethiscope to hear where this is coming from could be a idler or maybe the tensioner or maybe the alternator .. none of these would bother power

That Squeeling is your Belt. You may need a New Belt Tensioner to keep it Tighter. As a Quick fix, Go to your Auto Parts Store and get a Can of Fan Belt Dressing and spray this on the Belt and it will be Quite for a while. Please Rate my Solution, I need all the Help I can Get! Thanks!

Could be several things. WHICH ENGINE?.. 4 cylinder (has three belts, power steering/water pump, alternator & A/C compressor, one tensioner pully A/C compressor), The V6 2.7 (has only one belt, 1 Idler pully and 1 tensioner pully), the V6 3.5 has two belts - A/C/alternator, and power steering - there are two tensioner pullys). Noises can be caused by the belt(s) themselves, pullys, bearings, pully bearings, water pump shaft bearings (or belts/pullys rubbing up against something). Let's not forget that there is also belt(s) behind the Timing Belt cover as well as pullys and bearings associated with the timing system. You could start by removing one accy drive belt at a time (alternator, water pump, compressor, power steering, etc) to see whether or not the noise goes away in each case. If after each case, you discover the noise is still there, it's probably behind the timing belt cover (idler/tensioner pully, water pump shaft bearing, crankshaft bearing, etc.). Good Luck
