Just travelled back from Cornwall on getting halfway home we noticed that there was like a groaning noise or like a dragging sound comeing from our Alko hitch the noise was only noticable when slowing right down or pulling away any ideas if this is a major problem or a quick fix solution ?
Ours is a brand new van so the hitch is new, however like you it makes a groaning noise as we go over bumps etc, after unhitching I stood on the towball and as i moved found the groaning sound was coming for there am having it checked out this week by guy who fitted towbar.
Also is there anyone out there who can help me with the right towball for the alko hitch? I have a standard alko towball but have been advised that the alko works better with a swan neck.
If this is the case can I have a swan neck extension fitted or do I need to change the whole towbar?

As long as your caravan hitch is not contacting your car/bumper at any stage when towing, your standard hitch should be grand.With some tow-bars, the ball does not allow sufficient clearance from the bumper, hence the reason that some people have to have the extended ball.Swan necks usually all offer sufficient clearance .
To fit a swan neck, you'd have to fit a complete new tow-bar, but at the end of the day, you'd only be wasteing your money, and wouldn't be any better off.
The noise you descibe is a characteristic of alko hitches. It happens because the anti snake/pitch pads become dirty with use, and then you get the creaking noise like an old sailing ship. He He. I clean my tow ball and the pads inside the hitch with a solvent spray which does the trick. Short journies are ok, but anything over 100 miles and I get that noise.

If you have a standard ball and an Alko stabilising hitch then you would be advised to replace the towbal with the Alko towball which is designed for the stabilising hitch. The standard ball does not have sufficient clearance below the ball and it causes problems such as the ones you describe and also causes damage to the internal workings of the hitch which lead to premature wear and a possibility of the locking mechanism failing and the hitch separating from the ball. The replacement ball is about £20 and replacement is just a matter of undoing the two bolts and changing the ball.

I use a cleaner designed for electronic components, but any quick evaporating cleaner that doesn't leave a residue should work. I use the green scouring pad (scotchbrite) and spray up into the hitch, and clean that way. I think something like meths or industrial alcohol would work.
Try a tin of brake cleaner spray (aerosol)from a car parts supplier, spray it on the pads and on the ball then wipe off. It removes any build up of dust/dirt/grease etc
