If I am not mistaken, have a look on motorgeeks forum http://www.motorgeek.com/phpBB2/viewtopic.php?t=24201&highlight= The carrier bearing interchanges with a BMW part, the u joint interchanges with a Suzuki Grand Vitara. Read up on the forum and you will find out more. I hope this applies to the Urq aswell, as it should have the same parts as the 4000. Dave
