Returned yesterday from a lovely trip down in the surrey hills.
No problems at all until we got back to our storage facility. As we obviously slowed and started manouvering around the facility, particularly in reverse, this awful screeching noise was coming from the hitch. No problems when at cruising speed but just when it was slow manourvres.
I have no idea what it is. Despite the noise the hitch was all fitted on perfectly well and was fine, it was just this noise. The one thing I did notice was that once i had reversed it into place, I normally let the car go forwards a few inches to release the tension on the alko 'spring' thingy. This seemed reluctant to extend again, although ultimately did.
Has the hitch head had a service and grease?, there are nipples for use with a grease gun. If noise is coming from stabiliser hitch then you can lift the arm when manourvering on pitch\storage, also if there has ben any contamination of hte pads use break cleaning fluid to remove and de-grease.
if alko stabiliser hitch head then the pads need cleaning of dust.brake cleaner is good as you can spray it inside without removal of the pads.see also
I had the same problem but quite easy to solve, i removed both pads from the alco hitch the faces had a shiny coating on them i just removed the coating with some emery cloth also while you`ve got the pads out check to see if there worn down they may need replacing. cheers Stan
Its away in storage for the next few days but will be with it again at the weekend. I haven't greased the areas discussed personally (only had the van a couple of months) but will do that. I will also look to clean the pads and tow ball. I do Mountain Bike racing and have a disc brake cleaner which I use when pads etc get contaminated to clean them up. Would this be a suitable product to use?
Yes, that brake cleaner should be fine. I had the same problem recently and before setting off for my recent trip I sprayed inside the Alko hitch, let dry and then wiped out with a lint free cloth. I used a fine wet and dry sandpaper on the tow ball and then cleaned that too with brake cleaner before hitching up. Not a squeak this time, even when pitching.
