I talked to you already about the mounts in the PM and by the sound of the squeaks over speed bumps I bet its them, also I haven't paid too much attention to it but that also proves the fact that I don't hear the popping noise anymore when reversing. I'd have them checked out and like I said, make sure your struts are in good condition before replacing the mounts since they can do the job at once and save you the labor.

 

Squeak only when both wheels move the same direction at the same time (not when going over a speed bump at an angle)? Look at the sway bar bushings.

So if it squeaks going straight over a bump then check sway arm bushings if going over a bump at an angle check strut mounts? It even squeaks when hitting dips in the road but mostly going straight over a speed bump.

 

Is the top black disc part of the strut mount supposed to move when the wheels are turned back and forth?

 

Nope.

 

Yeah cause I had the hood up and I was turning the steering wheel back n forth and the black disc was moving.I guess that's next on my list.do I need one of those spring compressing things when I do it?

 

You either need a new mount, or the strut shaft but is loose.

 

I do get the squeaking sound when going over bumps and dips,I also get this rattling/tapping noise at highway speeds sometimes not sure if its all related.

 

Do I need one of those star things to try to tighten the strut nut and if I do what size is it.

 

Yes, a Torx bit, and a wrench. I don't remember the sizes.

 

Strange. That looks similar to my Deville, but mine had no Torx fitting on top like that picture above.

 

I know I don't even know if aap even has one that size.

 

Any parts store will have it. Remember you're looking for a socket, not a Torx screwdriver.

 

I'll check my work first, thanks for letting me know cause I would of probably looked for the screw driver type.I was wonder if I would have to have a heeman grip trying to hold that with a torx screw driver.I'll check that first before I replace it.

 

If the strut mounts are bad can they cause the car to ride ruff or shake on the highway?

 

No. They can squeak and clunk, and you may feel the clunk or a rattle through the steering wheel if they're really bad. Only very slightly though.

 

Can bad strut mounts mess with the alignment?

 

Yes, they locate the top of the strut. You can tell they're bad by removing that steel cone and inspecting them for tears and/or cracks, or by having a helper turn the wheel while you watch for forward/backward/left/right movement of the strut shaft/steel cone. There should be none.

 

Is the steel cone the black circular disc thing.so I can take the shaft Bolt off and pull the cones off to inspect?

 

Yes and yes. However, if your struts have lost their gas charge, the shaft may retract once the nut is removed. If the shaft begins to lower as you loosen the nut, don't remove the nut completely, just loosen it enough so that you can lift the cone a bit, and inspect the mount.

 

Oh ok thanks for letting me know that.one more thing about the alignment would bad mounts affect the the steering wheel being off center, cause I've had a few alignment s this year and every time the steering wheel is off center, inner and outer tie rods new and both control arms.

 

I don't think it would cause an off center steering wheel. That's caused by incorrect toe, or a tech that didn't center the wheel during the alignment. Bad mounts will throw off camber and caster.

 

Any particular strut mount to stay away from? What are some good ones delco,moog,Monroe? Oh yeah I was trying to take that shaft bolt off but I couldn't get it to loosen (need help) but when I turn the wheels back in forth the center strut shaft moves around anyways, so its probably a waste of time to get that nut off to check the mount if the shaft if moving anyway.

 

I would just stick with A/C Delco. They're not all that expensive.

 

If I have changed cv axles, control arms , inner and outer tie rods,and more on this car how hard are the strut mounts to change? any tips ,I do need one of those spring compresser things right?

 

Yes, you'll need a spring compressor. You'll need to remove the strut, hold the spring with the compressor, swap the mount, and reassemble.

Take a look at your spring isolators before you order the mount. If they're torn, or don't look too healthy, order new ones. They're pretty cheap, and replacing them will take an extra 30 seconds.

Have you inspected the other mount as well?
