Hi Mick, I think the reason for the price difference is because the front ones are often the first to need replacing. It is all about making money. Regards Peter.
Hi Andy, Have you checked the rubber seal round the windows? A piece of kitchen roll inside the rubber seal could give an indication of water ingress. The other possibility is water getting in at the bottom of the doors. I have had a teaspoonful in on the passenger side. Regards, Peter
