jasus, hard to hear it properly with that video!!!


sounds like the box though, maybe the diff, its hard to tell. Which would explain why the whine goes away once it warms up. No harm to change the oil in them if you don't know when it was changed last.

edit: I presume when you start it from stone cold and give it a few revs before moving off theres no whining?
