Clunking at low speeds - Ground Controlls.

[SHOspazz92]

The car has Ground Controlls with SHOsource CC plates and SHOsource Articulating spring mounts. The clunking happens when the car is turning left or right at very low speeds (Say, 5-10 MPH). It's pretty loud and I can feel the vibration from it on the floor and sometimes in the wheel. It's coming from the driver's side of the car. Where should I start looking?

*Edit*

Im starting to think it's the strut rod bushings or possibly the retainers. We'll see tommorow.

It's most likey the spring and articulated ball upper perch. As you turn the wheel, the spring loads and unloads, which causes it to chatter and make noise. Time to jack up the front end and re-grease the mounts. Try different kinds of grease to see which lasts the longest.

also maybe the ALSFB or SFB. maybe one bolt has loosened up.

Look at your LCA bushings, both on the strut rod and subframe. Just another place that can cause a pop/clunk.

Thank's Mike. What kind of grease did you and your father use?

I assure you they are nice and tight. :sun:

Turn wheel, open both the doors and have a couple buddies hang out and load and unload the suspension by bouncing. Hopefully you can replicate the sound while the car is stationary. You can find a noise like that quite easily if you can.

Synthetic wheel bearing grease, syl-glide, etc.

I think it's just one of those things that you need to do every month or so when the noise comes back. The penalty for a kick-butt suspension.

No doubt. The car had just been sitting for the last few months becuase I had not had time to replace the clutch. I had completely forgot about the noise until today when I was commuting in it to work (To put some mileage on the clutch) and got on to base where the speeds are very slow. Either way, Thank you all for your input. I will have an update either tommorow or Thursday.

I thought these were self-lubricating? Lubricating the mount wont damage the mount, or collect dirt and destroy the surface?

When you grease the spring mount Is there any particular way to do it? Or just Jack up the car, Reach in there and get it where you can? I just want to be sure I did it right in case the noise comes back, So I can look elsewhere.

no real trick. Pick the corner up off the ground, and put a few gobs of grease between the two halves of the mount. The point is to reduce the coeff. of friction between the pieces. Graphite powder might even work. Without lubrication, it goes into a stick/slip kind of chatter. It's hard to project whether or not this would lessen the life of the mount, but it sure is annoying.

You are right. The material used for the mount has self-lubricating properties. It's just not quite enough to get the job done.

The surfaces are finished as milled. A little wear will polish them nicely.

Adding a bit of goo isn't that hard. Consider it to be something you do with each oil change. It does make sense to wipe away the old grease before adding any more. No reason to let dirt hand around hen getting it out of there is so easy.

I think I found the Issue and it's quite suprising, Will post a video hopefully later tonight.
