Question about Cars & Trucks

I have a knocking noise coming from the left front end of the vehicle. Just wondering if it is the steering or something to do with the control arm. You can feel it at a slower speeds and feel in the steering wheel.

Could be a ball joint , tie rod , bad tire or wheel bearing. That's pretty much everything. Unless its front wheel drive? Then a CV joint can be added to the list :)

How do you tell if your ball joints or bushings are bad


Best Answer - Chosen by AskerWhat is the difference between control arms bushions and ball joints. There is a big difference between the two and the job they do. The bushion conect the control arms to the fram. There are two bushion per control arms. So there is a total of four per front wheel. Two for the upper control arm and two per lower control arm. It let's the vehicle go up and down. And is the back half of the the system that hold the coil spring in place with the two control arms. The ball joint are known as upper and lower ball joint. So you have two ball joints per front wheel. They hook in to the outter end's of the control arms. And hook to the top and botton of the spinner. They allow you to trun the wheel's to the left and right. Along with the spinner hole the outter side of the control arms to hole the coil springs in place. Putting the spring under pressure. In small a Srud is used and takes the place of the bushion's and ball joint's.
What has play in it? There should be some play but you should be able to move it by hand. Most ball joint's can be lubbed. If it still has play of a 1/4 inch it should be replaced. A really bad ball joint can pull out of the socket. This will cause the wheel go up in the fencer well. If the top one brakes loose the wheel will lay down. That is the danagous of the ball joint giving away. It will be hard to control the car to a stop. The bushion's will let moving of the part and wear out the front tires really fash.
I know you don't care to hear this. The car should go to a front end shop. Where they have the special tools to do the job safety. Pluse can line the vehicle back up. When it will need. It be cheaper than a roll over.

Steering wheel and front end shakes with knocking noise


easiest check struts for leakage or if the top nut came loose.
next Ball joints support bottom of lower control arm and try to move tire in and out on the bottom.
next check bearing plate for movement by trying to move top of tire.
last check tie rod ends by moving as in right turn left turn.
do both sides. if one side is bad replace both sides so you don't have to tie up vehicle in a couple months.

Thumping/Banging noise at the front end.


check front-end out, immediately, could be a bad bushing/ control arm, this would need attention, asap, you could lose control of vehicle, or somethingelse is broken, shock, but the control arm / bushing is my bet. get it repaired, unsafe condition !!!

2006 Dodge Charger front end rattle and noise. I have replaced both ball joints and lower conrtol arms which had loose ball joints. Still have a suspension front end rattle but the steering is tight...


Look at the brakwe strut arms that connect to the lower control arms and the cross member below tghe radiator. Also if it happens while making turns left or right into a driveway (knocking type noise , look at the sealed wheel bearings. I had this ande water waqs getting into the bearing through the dust cap

My Front left tire is tilted inward and underneath the truck i found one of the support bars that run's across is broken off on the left side. I looked around the wheel and found that no metal was bent so...


General Description
The front suspension allows each wheel to compensate for changes in the road surface without affecting the opposite wheel. Each wheel independently connects to the frame with a steering knuckle, ball joint assemblies, and upper and lower control arms.
The control arms specifically allow the steering knuckles to move in a three-dimensional arc. Two tie rods connect to steering arms on the knuckles and an intermediate rod. These operate the front wheels.
The two-wheel drive vehicles have coil chassis springs. These springs are mounted between the spring housings on the frame and the lower control arms. Double, direct acting shock absorbers are inside the coil springs. The coil springs attach to the lower control arms and offer ride control.
The upper part of each shock absorber extends through the upper control arm frame bracket. This bracket has two grommets, two grommet retainers, and a nut.
A spring stabilizer shaft controls the side roll of the front suspension. This shaft is mounted in rubber bushings that are held by brackets to the frame side rails. The ends of the stabilizer shaft connect to the lower control arms with link bolts. Rubber grommets isolate these link bolts. Rubber bushings attach the upper control arm to a cross shaft. Frame brackets bolt the cross shaft.
A ball joint assembly is riveted to the outer end of the upper control arm. A rubber spring in the control arm assures that the ball seats properly in the socket. A castellated nut and a cotter pin join the steering knuckle to the upper ball joint.
The inner ends of the lower control arm have pressed-in bushings. The bolts pass through the bushings and join the arm to the frame. The lower ball joint assembly is a press fit in the lower control arm and attaches to the steering knuckle with a castellated nut and a cotter pin.
Ball socket assemblies have rubber grease seals. These seals prevent entry of moisture and dirt and damage to the bearing surfaces.
Four-wheel drive models have a front suspension that consists of the control arms, a stabilizer bar, a shock absorber, and right and left torsion bars. The torsion bars replace the conventional coil springs. The lower control arm attaches to the front end of the torsion bar. The rear end of the torsion bar mounts on an adjustable arm at the crossmember. This arm adjustment controls the vehicle trim height.
Two-wheel drive vehicles have tapered roller sheel bearings. These bearings are adjustible and need lubrication.
Four-wheel drive models and RWD Utilities have sealed front-wheel bearings. These bearings are pre-adjusted and need no lubrication.
Heat treatment may create darkened areas on the bearing assembly. This discoloration does not signal a need for replacement.
Hope this helps?

I have front end noise in the front left.


I work for a Chevrolet dealership and am appalled that they couldn't or wouldn't help you. The noises in the Cobalt, HHR, Malibu, and any other ELECTRONIC POWER STEERING car that GM builds are too common to not know what is wrong!!!!

This is a bulletin for the noise issues:
#04-03-08-006D: Steering and Front Suspension Noise Concerns
This bulletin is available to any dealership to view. The tool used to find noises is called a chassis ear. It is a required tool for the dealership. Again no excuses for not finding the noise.

The most common issues are the intermediate steering shaft, steering rack, control arm bushings, and steering column. There are other things that can cause noises but these have been most common since 2005. Again there is no excuse for not knowing the car.

My advise is to try a different dealer and give them the bulletin number above, and good luck to you.

You would have to put the Jeep up in the air on a lift. Put it in 4wd and check for noises from the front hub bearings.
