front top hat clicks

Postby ttcheung97 » Tue Mar 19, 2013 9:23 am

School me a bit on the details of a shock mount; mine "clicks" when I push down on the car. I place my hand on the shock mount and feel some sort of vibration on the shock mount. Not loud, but you definitely hear it when the engine's off. The ride doesn't feel disconnected (or maybe I've gotten used to it), and the car tracks straight. I had an alignment performed recently by Motorsport Techniques and they never mentioned anything odd.

The clicking is only on one side; the passenger side shock mount does not click. The car has ~177k miles; the suspension is AGX with FM springs with about 70k miles on them, but still feeling good besides hearing the clicking.

Should this something of concern? Thanks in advance.

You *did* check the nuts for tightness, right?

the nut at the shock shaft? that i haven't checked closely, but will do that. if I tighten that nut too much (since it's nylock), does it just end up turning the shock shaft with it? I haven't put together a shock/spring assembly in a long time so i'm not recollecting fast enough.

That one too. Theoretically, it shouldn't back off precisely because it's a nylock nut, but it won't hurt to double check. Yes, it probably will spin the shock shaft, so you'll have to figure out how to secure that while you check the nut.

I damaged one very expensive shock while trying to tighten up the top nut by spinning it with an impact wrench, although I had done just this several times before with other shocks. The best way is probably to compress the spring, maybe second best way is to clamp the shock shaft with a vise grip and hope nothing bad happens to the shaft.

I checked the nuts, yes, they were "loose." But not "jiggly" loose, just not up to torque. The shock shaft nut was also a few lbs off torque, so i managed to get that tightened w/out rotating the shaft. The noise, for the most part, went away; thanks for the tips.

How does one usually torque the shock shaft nut if it rotates. I could've swore all the installation instructions I've read explicitly said "do not clamp the shock shaft."

Most of them have some sort of provision on the top for a tool to hold it still. That, plus a crow's foot socket on the torque wrench would be the right way to do it.

By chance, do you have aftermarket sways/sway links?

I was thinking that too, but he said he could feel it in the top hats. Doesn't mean it's not contributing, though.

no, the swaybars and endlinks are all stock.

i pushed down on the car again yesterday, and it was clicking again. it's almost like there's some sort of disconnect within the shock mount itself. i push the car side-to-side and it feels solid.

maybe it's just time to look into some new shocks. maybe just older car symptoms.

btw, Ken, the link on your signature is not working. I've been eyeing those door pulls your group initially had as the door arm rests are jamming into my seat's thigh bolsters.
