They're either loose, or they ain't. If not, we'll think again.

If you find nothing wrong, Spray some grease into the polys as best you can. If you have a spray grease can or copper shite spray can..?

[Diamond Black Geezer]

Ah, I've actually recently greased the NS (red grease, wasn't sure whether normal grease would corrode the poly as it does with rubber, so thought it safest bet)

It's what copper slip was designed for... hence why Poweflex supply a sachet of the stuff with the bushes

[Diamond Black Geezer]

Ahh, fair enough. The sachet of the copperslip is long gone (the polys were bought about 5 odd years ago, I nabbed them from the wishbones of Turbo Weasel I used to own) and therefore couldn't remember what kind of greasy substance was in the sachet. Will copperslip the OS tonight, then, save my red grease for rubber bits

you dont say if its worse one way or the other? however a little bit outside the box try the brake caliper sliders,can get wear and they do knock

Gentlemen, we have a conclusion 


Went in for the tracking/geometry first thing this morning (that's another story) and asked the mechanic to have a look while he was under there aaaaand... traced it to the droplink.

Happy to say that it was literally a quarter turn on the nut and she's silent. Now I think about it the droplinks were probably done just before I bought my torque wrenches, so I would have done them 'tight' but not too tight. I know for a fact that the Halfords spanners are rather fat, and so tend to be clamped (to the point where you can't actually remove them) when you tighten the nut on the balljoint, hence the last 'nip has to come without the benefit of having a spanner to stop the balljoint rotating. He checked all the others while under there, and they were all bang on, so clearly just one fo those things. I'll make sure they're torqued one evening, though, to avoid further issue 

Problem solved!

Oh, just to say, the wishbones are now torqued to OOF/Vx spec, including angle tightening, too  As ever much appreciated, chaps 

[chrisgixer]

Strange. Once in a bend, turning tighter still shouldn't give a drop link a chance unload and then load up again. There by giving the opportunity to knock. Unless the car goes through a level plain first the roll bar is way too stiff to allow the play to be heard, ordinarily.

[Diamond Black Geezer]

Tell me about it!

No ideal how that would be an issue under lateral load. Hence my putting such as droplinks way down the list of likely candidates, especially as they're new.

Also, why wasn't it knocking under general driving, and in straight line? Why only (apparently) in bends?    I'm not saying it never knocked when going in a straight line, but only on particularly rough ground, where all the suspension components are under considerable strain. I've always found that even the slightest little bump shows up a worn droplink.

So, unless the knock actually kicks off again, and that was just coincidence, at least I can sleep a bit easier - and got to Billing!
