i went out to my car, to figure out what the knocking noise is. i grabbed the tire on the yellow spots (see image bellow) and rocked it left and right (along the yellow arrow) and it makes the noise. grabbing it on the green spots and rocking it up and down (along the green arrow) and it doesn't make it... i figure, that due to the geometry of the links, the only thing it can be is the toe-link. i don't know if its the inside or outside bushing... but that is unimportant because i'm going to replace the toe-links and bushing with either the rx7store ones or the rotaryextreme ones. is my prognosis a good one???



please leave this in the 3rd gen room as its only to do with suspension on an FD... thanks p.s. i found the picture on yahoo search, if its yours and you want credit or for me to not use it anymore, please let me know but for now, i hope it helps

 

Grab the toe links and verify that's where the slop is. Could be ur bushings on the upper A-arm or perhaps pillow *****.

New trail links or toe links with rod ends is a good mod to stiffen up the rear suspension so you might want to change them anyway.

 

More than likely it's one of the pillow ball bushings. Jack the car up, take the wheel off, shake the rotor and determine the source of the noise. If you can hear it you should be able to see which bushing actually has play in it.

 

i already jacked it up and shook the crap out of it... it looks/feels like the play is in the toe link. who knows... is there anyone from MD that knows what they are talking about that is willing to meet me somewhere (near baltimore) to check it too?

 

If the toe link is bad, you should feel some movement in it when you try to move the arm itself. Grab the arm and shake it. The stock toe links are every bit as good as the aftermarket ones, and they will last longer. If you decide to replace them, just get the OEM bearings, and have them pressed into your existing arms.

Replacing bearings that are still good is a major waste of money. Make sure they are bad before buying new ones.

 

Replace all the pillowball bushings and it should fix that problem, it worked for me.
Just to be sure change toe-control links.
