It’s possible that the front wheel needs to be lubricated. Give this a try – take out the front wheel, wipe it clean with a rag, then get some vaseline and apply a small amount to the metal pin. Put it back and move it around so it coats the front wheel housing.
This needs to be done every 6 months as part of servicing.
