If Ford specs don’t require lube originally and the car was delivered without clunks/rattles, then lubing the jounce bumpers later down the road seems to be masking an underlying problem. Throwing some gunk/lube at it seems to be dampening the clunking sounds I had. Right now I’m two weeks post lube service and so far no noises. I wonder what happens when the lube eventually gets depleted and thinned out, does the clunking/rattle come back? I’ll post if anything changes. Perhaps it’s pointing in a right direction. Is there a design flaw with jounce and bumper design or their interface? Can the bumper be loose from its base? Is there a problem with the materials used?
If anyone has access to these noisy pulled parts, could they examine the jounce bumpers and related parts to see if anything looks at amiss? I assume the Ford Engineers are following all the documentation/invoices and getting to the bottom of this?
