Check the rubber mounts on the bottom of the shockers first........turn wheel outward as far as it will go...grab hold of shocker at the bottom, and shake. if there is too much movement, then this is your problem

Raised the vehicle with the front tires off the ground,and grab the front end parts they should move very stiff or not at all,if they move very easy that part is in need of replacement.

Check for bad wheel balance, struts, lower ball joints ( no upper joints) , outer tie rod ends, inner tie rod ends, stabilizer bar bushings, lower control arm bushings , and finally a wheel alignment ,you have some bad looseness in one or more of these front end parts. GOOD LUCK FRIEND.

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.

I have a 1997 Jeep Grand Cherokee, Im getting a rattle under the jeep. It sounds like metal hitting metal its not the exhaust for that is not hittig anything. it sounds like its to the rear. Someone said...


Your jeep has two upper and two lower control arms attached to the rear axle. They have rubber bushings where they bolt to the axle and to the body. If the bushings are badly deteriorated, you will get a metal to metal sound when hitting bumps. Have them all checked.

Rattles really bad over bumps sounds like the front end is gonna fall off


I have a 2002 Escape 3.0L with 120,000 miles and have had a couple of rattlers.
The first was a constant light rattle. It was the sway bar links.
The second sounds like what you've got. Occasional rattle, but nasty on bumps. The rear bushing went bad on the passenger side lower control arm the control arm was banging on the "frame".

Here is a picture of my new control arm. The bad rubber bushing was the "lowest" one in the picture, near the vise.

zeevert_32.jpg The control arm was the cheapest from the Ford dealer; maybe $50? Repalced it myself. Not too easy.

2003 chev trailblazer creeks as you stop or hit bumps


A few things to check, I'm going through this as we type here, and have narrowed mine down to the front A-arm bracket, which is located on the bottom of the frame with bushings.

Check your swaybar links (if you replace, I like Moog brand,it's greaseable), swaybar bushings both front and rear for both. From there, check the a-arm bushings , and finally, the upper and lower control arms. The way to narrow it down further with bushings is squirt silicone lubricant on these bushings and see which one i creaking. Forgot one more common squeak, it's your hood latch, lube it up good and adjust the hood stops up a bit and use some rubber lube for the stops( Napa has this) . Had that squeak for 7years until last weekend, dealer couldn't even find it.

What r problems to be on the look out for on a 1999 chevy malibu with the 3100 v6 in it and there is a rattle when i hit bumps or rough road the struts are fine


Broken stabalizer links, broken stabilizer bar, and worn out stabilizer bar bushings are fairly common. As well as the rear bushings on the front lower control arms. A quick inspection of the front end and you should be able to tell if the links are bad, bar is broken, or the lower control arm bushings are separated. If the rear bushings on the front lower control arms are seperated the lower control arm will look like it is resting on the subframe.

Sounds like broken spring, or collapsed suspension strut, or collapsed wheel baring, or broken upper or lower control arm or extremely worn bushes, or all the above. what is it your driving? what sort of bumps? speed bumps? or 4x4ing bumps? or just general bumps in the road?

Front driver side suspension knock over bumps


See if you can bounce car and replicate the noise. If you can, you should be able to find it, and put your hand on it. Stabilizer bushing are a place to look, both at the lower a arm and on the frame. If you narrow it down to the strut, it will need to be replaced. The front trans mount also goes bad, try putting it in drive with your foot on the brake and give it some gas and see if the engine moves an excessive amount.
