Clunking Coils - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Enrgkid · 03-08-2021, 05:21 PM

Hi All,

I have installed brand new Silvers Neomax S, and now when I'm driving I hear a clunk from the suspension, I cannot determine where the noise is, I have checked all the bolts. I undid the lower bolts on all four corners and then reinstalled, ensuring they were each under load when bolting it back together.

Anyone got tips on what it may be? I've read it could be top hat bolts, but I don't know what talk they need to be?

Cheers in advance.

Were the springs captive when you installed them?

I went in and tightened them all nothing crazy but regardless still tightened them. No slack in the springs etc.

Worn sway bar endlinks?

I got new ones for the front but not the rear, might look to get new ones for the rear

Check if every bolt is torqued to spec.

When you've jacked up the car try to rock the front wheel (push the top outside in and pull the bottom outside out and then the opposite) if you were in front of the car you'd be trying to make the wheel go / | \ (so not rotation you'd have for turning the wheel, it's trying to make the top and bottom of the wheel move in and out).
If it moves a lot (we're talking centimeters, usually you could like slide the wheel in with a loud clunk and it would stay until you pulled it back) you probably didn't tighten the large bolts at the knuckle enough (they should not move and need to be very tight with a high lb-ft).

If it just moves a little check to make sure the lower collar that tightens to where the shockbody enters the lower mount is fully tight. I had an issue with that lower mount getting loose on my FA500 and then I got a clunk when turning, they recommend using a flathead screw driver and a hammer to force the collar to rotate, the tools people think are for tightening are meant just to adjust the height, they will not tighten it enough to hold.

Top nuts also come loose along with swaybar end links causing a 'clunk', zap those with an impact driver.

My left rear started clunking a few days ago after hitting a pot hole.
