Sorry my first post is not a good one. I've been on the forum for nearly a year and normally find everything I need by search, but need a little help and advise. Last week I was driving along when there was a bang front the car, it felt like I run over a brick. I drove a bit further and the same thing happen again. Since then I have had a whirring/rumbling noise from the front off the car, which goes away when I press the clutch in or press the accelerator. The noise is road wheel and not engine related. I have replace the o/s driveshaft as the inner boot has split and the shaft was a pattern part. I've also replaced the o/s wheel bearing, but the noise is still there. After reading on the forum, I'm thinking that I could had dropped a rivet off the diff and damaged the gear on the diff. Any help will be appreciated before a fork out for a new gearbox and clutch/ flywheel while the box is off.
