My doblo cargo van has started squeaking/rattling and had it diagnosed by a specialist as 'the thrust bearing'. They said its strange though, as depressing the clutch makes no difference to the noise but were 100% that its the thrust bearing?!! Quoted £795 to replace dual flywheel and clutch. My usual garage say there's no need to replace the DFW and quoted £350 to do the clutch. Any thoughts?
