Guys and girls I have a strange issue wheni fill the car up it squeeks and gets louder I think its a weight issue as it comes from rhd side any ideas how to resolve this problem

Mouse? Lol

It'll be a dry bush somewhere, reverse up onto a set of ramps and get someone to bounce the back about a bit while you ars underneath with a can of wd40, when you spray the offending bush itll stop squeaking and you will know what one will be needing changed soon.
