Well I eventually got shamed into getting rid of the front end clunks in the
16V that had everyone convinced it was in fact a pop corn machine on wheels
When little old ladies keep asking "Wot's wrong with yer car???" you
know it's time for action.
Did the usual check list; brake pads - check; OK
Movement in drop links on sway bar - check: OK.
Ohoh!! here we go; big problems - I think to myself.
Check upper & lower, control arms, ball joints, tie rod ends, pipes, cables,
cross member; all checked out OK. Put suspension up; down, in the normal and
high settings; I jumped the front up & down, kicked wheels, pulled, pushed,
swung off top & bottom with handbrake on & off, used jacks to take the
weight off and iron bars to put load on and guess what? Not a sound!!!!
Decided that I'd start at the drop links anyway so I removed the RHS one first.
Looked OK but was a bit tight I thought, so I removed the dust cover to have
a decent look. The grease was black and obviously water contaminated so I cleaned
up, smacked the bottom joint from behind with a ball pein hammer a couple of
times and it suddenly freed up. Took the dust cover from the top one and did
the same thing followed by a tapping around where the ball is retained in the
drop arm (which I think Bob Smith has recommended in the past) regreased both
before refitting the dust covers and refitted to the car. Noise gone.
I have suspicions that these things wear, grease becomes moisture contaminated,
and then bind inside the ball housing thereby causing a cracking sound as they
move, which duplicates the sound of loose brake pads we all know and learn to
live with on BX's but to a louder degree.
The big problem is that the noise cannot be created with the car stationary
as it depends on the wheel moving up and down rather than the car, so movement
is a necessary factor.
Best news is that it only takes half hour to do and apart from the fact that
you no longer make heads turn when you drive down even a smooth street, there
is an instant improvement in ride and handling due to the smoother operation
of the drop links to the sway bar.
