bushings? is anything rubbing anywhere it shouldnt be?

[genericforumname]

not 100% sure myself but your tire seems to be sitting up against the fender, when you were pushing down on the car the tire sidewall was bouncing along with it. Probably is rubbing pretty bad there. other wise are they new springs on whatever suspension you're using?

Oh wow, that was significantly different than expected.

Check your tire to fender clearances, and see if they're making contact (though you would see wear with the amount of noise it's making).

It almost sounds like a bushing, have you recently changed your ride height without correcting the bushing loading? Also, check to make sure that all of the bushings are properly torqued and not staying stationary while the suspension is moving. Grease all of your aftermarket heims, and any poly bushings too.

check the top mount of the shock.

i recently bought the coilovers and wheels there is no rubbing between the fender and tire or anything like that but i was making that noise before and the bushing shouldnt be that bad the car only has 110k miles but maybe there dried out

Try spraying some grease on the bushings and see if it goes away

One of my heim joints does the same thing. It may just need to be cleaned and lubed if it isn't damaged.

i like your video. what kind of rear suspension do you have (oem, chinese coils, quality coils? arms etc)

[e1_griego]

Sounds like a rod end. Hit them with lubricant or just replace them.

someone else should do that while you try to hear where its coming from

Here's a bit of insight in case you can't find the cause of that squeak in the obvious places... uhh where to begin...

So, basically, it's possible that the squeak is from busted welds that hold the sheet metal pieces together on your car. In the rear of a 240, you basically have the wheel that's connected to a shock, and then the shock is connected to the shock tower on the upper mount. Sometimes, if you're real unlucky (or if you've got a ton of miles on your car) you'll go over a bump so hard that the force will travel from the ground to the wheel, to the shock, to the shock tower, and literally force the sheet metal on your shock tower apart from the sheet metal towards the middle of the car.

From what I can tell, it looks like some pieces are just held together by tack welds in strategic places. And when the force from the ground is strong enough, the tack welds will break. Then, when force is applied to that sheet metal, it'll move against the other piece of metal that it would be welded to, causing an annoying squeak.

If you've got a rear tower strut bar, try tugging on it with some weight and see if that causes noise. Also, if you take your interior apart, look for popped-off welds and surprise tears in the sheet metal. On my s14, I had torn metal by the upper shock mount on the interior of the car, also some visible from inside the trunk, and some visible from inside the wheel well.

I hope that you don't have to deal with the caca that I'm dealing with now, but at least it's good welding practice. Good luck!
