Hi chaps Bought a mk2.5 focus last weekend got some questions about the IB5 gearbox from what I have read not the best of gearboxes

Don't have any problem with the gearbox selecting any gear including reverse no problems.

But the Reverse noise on the car, Don't recall hearing this in any other gear but while reversing backwards it sounds like a dry bearing the pitch of the noise is nothing I have heard in anyother car I have had before mostly diesels to be honest 2.0tdi's

Thoughts?
