My quinny buzz front wheel
First remove the front wheel assembly from the pushchair by pressing in the two buttons on the sides and pulling it out.
Now look more closely at the assembly - on one side, just where it bends at an angle you will find a small hole, a couple of millimetres across. Take a small screwdriver or some other thin object and push it into the hole a little way, which presses a metal catch inwards, releasing the swivel assembly. While continuing to push this in pull the swivel assembly apart - grasp the wheels in one hand and the L-shaped plastic housing in the other and pull them apart.
Now clean all the surfaces with a piece of strong cloth.
When all the surfaces are very clean, take a can of TEFLON SPRAY and spray it onto all surfaces that rub against each other, before reassembling the wheel unit. Silicon grease is a cheaper alternative, but the teflon spray is supposed to be the best for lubricating all moving parts on the Buzz. Whatever you do, don't use WD40.
Hope this helps! Dan.
