Default strange sounds

ive been noticing a weird sound, it only happens when i make right turns, and only when the turns are somewhat spirited it can best be described as a very low groaning sound, i originally thought it might be the sidewall of the tire hitting the pavement because the fronts were a little low, but even with them properly inflated it still does it. any thoughts?

Maybe sway bar bushings, control arm bushings? I think the sway bar links are too little to make a groan, but ????

Get under the car and check it all. You should be able to move things around by hand to figure it out.

what exactly would i be looking for? just worn or cracked bushings? maybe something needs a shot of grease? i definetely couldnt get it to make the sound while not moving, it only does it when moving and taking corners at decent speeds....not like going insanely fast, but enough to make the car roll a little bit ya know? im not in any danger am i? the car still feels fine when driving it.

Because the sound only occurs during cornering, I would look at the sway bar bushings and end links first, then the control arm bushings. If you see any rubber crumbs around the bushings, that may be the source. Another possiblility is that your sway bar is cracked. Look closely where the bar transitions from round to flat on the ends; that is a common place for failure. I suppose worn or loose end-link bushings might produce a groan. The endlinks are pretty cheap and easy to replace. If your ball joints have grease fittings, a few shots couldn't hurt. But I would not put petroleum based grease on any of the bushings. If I thought one of the bushings was making noise, I might try a silicone spray, but to be honest, I have never heard of lubricating these bushings.

I might be inclined just to replace the noisy bushings if I found one.

Have you tried bouncing the car really deeply to reproduce the sound?

OK, in the drawing, #1 is the sway bar (stabilizer bar), #2 is the sway bar mount comprising a steel bracket which tightly holds a rubber bushing around the bar and bolts to the frame crossmember. #3 is the end link which comprises 4 bushings, 4 big washers, a sleeve, a center bolt and a nut. The link connects the sway bar to the control arm.

The control arm is the 'Y" shaped part attached to the frame side member at two points corresponding to the top of the "Y" These attachments are isolated with rubber bushings. At the outer end of the control arm (the bottom of the "Y") is the ball joint where the bottom of the steering knuckle attaches. The ball joint will sit right behind and about six inches below the center of your wheel.

These are the parts we have been discussing.

Hope this helps.
