I've noticed a lot of creaking recently from the alko stabiliser fitted to our caravan.
I replaced the friction pads but that made no difference.
The towball itself seems ok - I did make the rookie error of not removing the paint before using it, but the paint is now long gone and it is bare metal and looks ok, although it has got some scratches on it. I've sanded it a bit with wet and dry paper and cleaned it with brake cleaner.
Has anybody got any other suggestions, apart from turning the radio up when towing!!

I Know this sounds daft, but the ball may be too smooth, score it with rough emery to give the pads something to key on
no sorry to say you are wrong in your posting.the pads are smooth and grip onto the smooth ball really tight,if you rough up the ball it will damage your pads at great expense.the same as your brakes work when pushed onto the drum or disc.
------------- the only silly question is the one you do not ask.
Try thoroughly cleaning the pads with motorcycle brake cleaner. I used Muc-Off Disc Brake Cleaner from Halfords. Spray some over the pads and rub the pads clean with kitchen roll paper. Repeat this until the paper comes away clean. In my experience this will significantly reduce the creaking noise, but probably not totally eliminate it.

I dont mean to be rude, but I disagree with you and agree with Steve. The pads are not smooth they are rough. If they were smooth they would not be a friction material.
That's why when you wear your pads down on the car to the metal they do not work.
What happens when you wear smooth shoes on ice/snow you slip. When you wear a pair of boots you don't slip, that is because you boots have something to "key" against.
I light roughage of the tow ball will no no harm, just make sure you don't wear away too much.
You also say you have changed the pads, have you changed all 4 pads?
Don't make life difficult for yourself. Follow the simple method of 'clean is good'. Give the pads a thorough cleaning with brake cleaner and use a micro cloth instead of kitchen towel, that way no paper residue will stick to the pads. Also clean the ball off before each coupling up, even when packing up to come home. I would suggest that if you are going to rub the towball with anything that you use fine emery cloth and nothing more abrasive than that, the coupling and the ball are all that keeps your outfit together, treat them with the utmost care and respect.
I also had this problem with my alko stabiliser. Spoke to the guy who fitted my towbar. He told me to give the pads a rub down with fine emery paper and clean off with white spirit. Worked a treat, not had a creak from the stabiliser since.
We had a very noticeable creaking on our Alko stabiliser for some time despite my attempt at cleaning the friction pads. When the van was taken in for annual service in January I mentioned it to the service reception. He said that behind the coupling there are a couple of nuts/bolts which sometimes are not fully tightened and which can cause a creaking problem. Not sure if he meant the two nuts/bolts which actually secure the coupling or others further back the A-frame. Anyway the service engineer removed and checked the pads and there was still plenty of wear on them and also assumed he torqued the nuts in question. The creaking has stopped since I collected the van. So if anyone also has a problem it might be worth checking your nuts.
