Look to see if the bushings on the bar are worn, also check to see that the metal washers are in good shape. Sometimes, you may need to remove the center bushings, and grease them, sparaying does not get inside of the bushings.

Why does my 2007 ford edge se squeak when going over bumps or imperfections in the road or pushing down in rear bumper?

In the old days, 50 years ago, cars had their oil change every 3,000 miles, and they received a "lubrication" at that time. ( Some "lube" jobs were a "lick and a promise".)
Conscientious mechanics would spray lubricant (like "Ruglyde") on all the rubber joints, to help quiet them.
Today, no one does that.
I suggest you find a garage that has a drive-on hoist, and drive it on and raise it up in the air.
Then pull or push the areas of the car, and you may find the location of your squeaks.
Hopefully, you have no worn out parts.
God bless your efforts.

Squeaking noise when i go over just the slightest bump on my 2004 chevy trailblazer

There are a number of rubber bushings in the suspension of the truck. Try to at least isolate the squeak to the front or rear, then spray silicon lubricant on the bushings in that area.

Check your sway bar links, the two bars at each end of the sway bar, connecting to the lower control arms. Sometimes you can spray them with silicone. Most likely have to replace them. Hope this helps. TJ

My front in squeeks an creeks when i hit a low spot or bump. I have had in the shop 3 times> I bought an extended warranty. I am bought ready to give up.

Front end squeaks are usually caused by rubber suspension parts. The most common source are the sway bar bushings. Nest would be the control arm bushings. You can spray the bushings with penetrating oil to see if the squeak stops. This would only be a temporary fix. Do the sway bar bushings first. Spray them down really good, and drive the car for a couple of days. If the squeak goes away, you will know you need to replace the bushings. Do the same thing to the control arm bushings. If you replace any of the bushings, use a high performance neoprene bushing, and use the special lube available before installation. The sway bar bushings will be an easy fix. The control arm bushings will require special equipment, and will need to be done in a shop.

Have a 05 sebring sedan. front end squeaks in the suspension when it gets warm. have replaced everything in the the last year. what else could it be.

Usually squeaks are rubber bushings that need liquid soap lubrication. The anti-roll bar bushings and end links are common sources. So is the lower arm bushings that work with the strut assembly. Suggest getting under the car while someone pushes down on the front end to get it squeaking. Good luck!

Car sqeaking when going over bumps

It could be the wishbones, the springs or the inside panels rubbing which is also very common. Also, some shocks have plastic shields on them that tend to squeak

2000 Ranger front end squeaks

There's a bunch of rubber to metal connections under your truck. Suspension parts, body mounts, sway bars, etc. See if you can find rubber lubricant in a spray. In the good old days, mechanics would do that for you when you got a lube job. Speaking of lube jobs, your truck does have ball joints. If it doesn't have lube fittings, see if you can get some put in. After nine years, your ball joints could be worn out, too. If you get new ones, try to get ones with lube fitttings.

Squeeky windows and front seats

Go to the auto parts store and ask for advice (They are usually very helpful especially Advanced Auto Parts) or purchase a can of dw40 or similar lubricating product and spray the seat metal joints under the seat.
As to the window, if it's squeaking where the glass meets the rubber spray the rubber or treat it with armor all.

Hope this helps!

1992 toyota landcruiser squeaking

Actually, there are not a places to lubricate, other than the Rzeppa joints (those at the big ball & socket looking things right behind the front wheels). That being said, here is what I would look for if it was in my shop:
Examine the front sway bar bushings. They may be bad or worn. Rocking side to side will move the swat bar. Look at the bar, there are 4 bushings; 2 at each end, and 2 under the center of the vehicle, held in by a "half-moon" looking clamp. Spray WD-40 or something like that on it real good & drive it.
Get back to me if this does not help.
