Suspension noise SC&C control arms..

I am getting this weird noise. When I turn all the way to the right it makes this little click like something is catching then when I turn to the left it goes almost all the way and then makes a loud banging sound like somethings being released when the click sound was made.

Just concern yourself with the banging the other grounding sounds are from the two pieces of sheet metal under the tires..

The noise goes away if I jack the car up an inch or so from the middle of the frame.

Thank you!

I think I’ve heard that sound once when a spring snapped into the upper pocket correctly after changing the springs up front.

Me too Jason! I know I've heard this sound before. I am pretty sure its coming from the spring. I think I need to raise the front end up a little since the noise goes away. These are the problems you run into when you put after market parts on your car..

Not sure what sc&c upper arms you have, might want to check your main cross-bolt if you have one. Mine was a little loose and made that exact noise. The arm was actually moving fore and aft and would pop when it traveled. Tightened it up and no more noise.

Re: Suspension noise SC&C control arms..

Is it just me or does it look like one of your PS hoses jump every time it makes the noise? Something binding there, for sure. I think the BEST way to diagnose this is to lay under the car and feel the suspension parts while someone else does the steering.

Yep, I was going to suggest just that. I'd start with hand on upper, then lower control arm on each side, then knuckle. What about steering arm that bolts to the knuckle?

Re: Suspension noise SC&C control arms..

Check the adjuster nuts on your tie rods, may be making contact with the sway bar.

Re: Suspension noise SC&C control arms..

I cant find this noise. It has me worried. I'm going to go over the brake calipers today. I wonder if its the shocks or cracked front springs?

Re: Suspension noise SC&C control arms..

Did you recently install new front springs ?

The "flat" end should go to the top.

Maybe measure both front fender lips to see if the heigth is the same ? Indicating a spring not seating correctly ?

Could the steering linkage be hitting the frame ?

Re: Suspension noise SC&C control arms..

The shocks and springs do not move while turning the wheel when the vehicle is not in motion. I would place my money on a tie rod end, center link end, idler arm, or a ball joint. It has to be in one of the moving parts - I can not see how the stationary parts would cause that noise.

Just as a test, jack the car up with the front cross member (just to get the tires about 3" or 4" off the ground). Do not place any jack stands under the car (so that the suspension is in full droop). Reach in through the window and turn the wheel lock to lock. Is the noise still there?? If not, then something is binding when under the pressure of the vehicle weight on the suspension. I would be looking at all of the twisting/rotating parts that I listed above.

Re: Suspension noise SC&C control arms..

Not that this is it but why is the bolt head so far away from the idler arm where it bolts to the frame. Did you check the 2 nuts that bolt the upper arm to the frame where the shims go. Some of these aftermarket a frames have faulty ball joints in them that end up snapping off.

I was thinking of the same thing but the only thing he may get another noise if the sway bar bolt comes in contact with the upper ball joint stud.

Maybe, maybe not. My sway bar end link bolts don't hit my upper ball joint at full droop (I have UMI uppers/lowers, with Viking double adjustable coil overs). Even if they do touch, the ball joint stud should not be moving, so he shouldn't have any new noises.
