Clutch howl?
Posted: 25 Nov 2010, 09:36
Hey guys,
I've been getting a dry howl when changing gear under load for the last few weeks. It does not happen during normal driving, only when either changing down when decelerating or when using higher revs than normal when accelerating. Obviously, this is my precious van and I don't drive it like a teenage caffeine freak, it gets treated with respect! I only say this to give you a realistic idea of the forces I'm talking about in the transmission. It sounds like brake howl but lower in pitch, and takes place in the gear change at the point that the plates bite, and increases from a quiet 'hoot' under gentle load, to a pronounced 'howl' under slightly more load. The problem does not seem to be worsening (as you'd expect from a worn clutch). I am wondering if my vehicle may have been fitted with a limited slip clutch which is developing a fault, as its a T4 Syncro and I've seen articles relating to Syncros being fitted with 'oiling plate clutches' to protect the transmissions. Has anyone either suffered from this themselves or come across it on other vans?
Thanks guys
