On my 99 Grand Marquis , which is in great Granny Car shape, has started to creak, squeek and moan. but it only happened to start after it was put on a lift and all for wheels were allow to drop. I assume it is the front shocks… but I want to check with you guys first….
every up and down makes the noises… but also when stopped and just turning the wheels

Well how i usually find these noises is have an assistant either turn the wheels or bounce the car which ever duplicates the noise and if its something obvious like a lower ball joint ill carefully put my hand on the lower ball joint and feel for the noise usually you can feel it.
Yeah, could be anything that is moving in the steering or suspension. I’ve even encountered where the frame would creak. As K5mudlife stated, you have found it when you’ve found it.
🙂 Your Marquis is 15 years old and if you are in an area that gets snow, you are subject to rust in your suspension. From your description of the problem, it sounds like your upper and lower A Arm suspension bushings are going out. They have gotten old and are dried up pieces of rubber suspension pieces that mount the A Arm to the car’s frame. Also your shocks could have bad bushings and are causing the problem, but I would look at your suspension bushings in the Left and Right, Upper and Lower A Arms. When you take the weight off the suspension when you lift the car up, you are unloading the suspension and any noises that occur are from the bushings squeaking from being old. This is a common item to happen to older cars and trucks as time will make the rubber deteriorate. It is not a very hard job to replace the bushings, but it labor intensive and will require being able to press out and reinstall the bushings in the A Arms. I am not sure if complete replacement A Arms are available any more.
If you plan on keeping your car then you will need to have the bushings replaced, If this is just a old car for you, then you could spray some silicon spray on the bushings and it will quiet them for a while. Good Luck.I agree with the above about worn out rubber. My wifes Impala had dried out bushings and was loaded with rust (thanks Indiana). I found it cheaper and easier to replace the entire A-arm as it already had a ball joint, and pressed in bushings (I purchased most of my stuff from AdvanceAuto and RockAuto.com; I’m not advertising for them, just mentioning they have a lot of parts online that others don’t seem to carry)
For our 91 Suburban, I did press in the front bushings for the leaf-springs, but for the rear I used polyurethane bushings. I plan on using polyurethane for everything now as they were a huge time saver and the ride was just as comfortable (it is a suburban though).
In my experience, once some of the suspension starts failing, the rest isn’t usually far behind. Unless this is going to be a beater car it may be easier to replace all the front (then the back).
see if this helps.
