Ok, firstly I'm getting a kinda buzzing noise all the time when the engines on, regardless of throttle etc, coming from the right rear. I'm no expert but I'm guessing the fuel pump perhaps?
Secondly, a kinda whirring noise when I lift off the throttle.. when its on overun basically, and as soon as I re-engage, bingo its gone. I'm dreading that its the diff, but if anyone can shed any light on either I'd appreaciate it... Maybe try changing the diff oil?
Been trying to ignore them with the stereo on loud tbh.
Any ideas people?
