Got the rear end clunk in my 2012 MCA V-6, 33,000 miles, D55 Brembo lowering springs on rear was only mod. To try and remedy the clunk, I replaced LCA with GT500 set and I greased and re-torqued sway bar links and mounts. This reduced the occurrences of the clunk, but did not get rid of it completely.
I went to local dealer and ordered two replacement sway bar links. They came in, but appear to be incorrect parts. The end of the link which slides onto the sway bar seems to be about 4mm too small, compared to 22mm diameter of old link.
I have left the sway bar off the car while I try and find the correct part. Good news is, the clunk is gone. Bad new is, Ford dealer has no idea what part I need.
Comparing the two links, I notice the sleeve on the end of the link which mounts to the chassis is centered on the new link and protrudes past the link and rubber bushing on both sides. On the old link, the sleeve sat flush on one end. Seems this would allow metal to metal contact and create the clunk over small bumps as the rear suspension binds.
So, after all this rambling, I guess I am looking for two things:
First, anyone run into the issue of having to figure out which link is needed for a 22mm rear sway bar? How did you resolve it.
Next, anyone replace the links and find the centered sleeve cured the clunk.
Efforts here are trying to fight taking car in and fighting for warranty work and trying to avoid spending $300.00 on an aftermarket sway bar and links.
Thanks in advance.
