I'd never done this before - but wish I'd done it earlier, the difference is phenomenal. Both my cars have squeaky suspension and this has cured it.

Get yourself one of these:



They're less than £8 and are more than adequate for the job.

You'll also need this:



Or this if you're so inclined:



Under your car, locate your spring cans (you can't really mis them, they're very round and very can like.) A little in front and behind each can you'lll see these:



Gently pull the rubber back:



You can then insert the smaller tube in the hole. Keep inserting it, it should go in about 18".

Stick the other end into your oil:



And pump away. I easily emptied a one litre bottle and the cans would have taken more.

Van now drives smooth and quiet. No Squeaking.

Extra bon.

Did I detect sexual undertones Or subliminal messages in this one!

worryingly I didn't intend it to sound like that at all! It just came out. Oh dear. This doesn't bode well for 2cvGB!

Sexed up 2CVGB News.

Sam,
best keep away from any areas of posh new block paving for a while, if you've put half a litre of oil in each canister...

Also watch out for MOT testers telling you that your "dampers" are leaking.

Or you could use a washing up liquid bottle filled with the oil and some washer hose...

I always heard that sunflower oil or similar isn't that good a solution, as it only takes away the noise.
With castor oil the frictionmaterial is able to do what is is supposed to do (damping).
At least, this is what Jeroen Cats always told.

Isn't it the springs that do the damping? I couldn't remember if it was engine oil or castor that rots the rubbers, guess that's engine oil

jeroen cats told me the friction material was there for the 2cv that had no telescopic shock absorbers.
it's an organic like material, that dries out, which makes the squeaky noise.
you need something that lubricates as well as penetrates the material. Castor oils seems to this the best

Other oils make the noise go away, but don't penetrate in to the friction material, so it give friction to the arm movement.

I have a bit of text about this, but it's in dutch and is has some words in it that are hard to translate

Tom & Sam,
sorry to disagree, but my view is that any damping of suspension movement is provided by either the friction damper/inertia damper combination or by hydraulic dampers, with the latter sometimes used in combination with inertia dampers.
That lining on the suspension cups is solely to provide a durable sliding surface.

If you think about it, the last thing you'd usually want to do with _any_ material which is designed to provide friction is to lubricate it, thereby reducing its coefficient of friction
That goes for clutch linings, brake pads or shoes, friction damper mechanisms and so on...
