Horrible Noises - X5

[DaveG28]

Finally put my leccy bits in my X5 tonight and gave it a quick spin.

Anyway, couple of quick issues:

1. It makes a quite horrible noise during acceleration, I think its either the belt or spur. Anyone know what noise a car makes when you run the pinion too tight against the spur?
This sounds like somethings slipping though, so I'm guessing its the belt, is that normal for an unused old X5? Is my quick fix the one where I make a belt roller to tension it up a bit? FOr anyone who's run them though, do they make horrible noises when the slipper/diff is loose, or do they sound like any other car ina similar state (I bought this car built and have never used a LOSI or similar before, so not sure if there's anything different in the drivetrain!)!?

2. There's bugger all lock on the outside wheel, but plenty on the inside, is there anything I can adjust for this or with a one way etc do I not need much lock? My servo is spannered I think (dumped an old one in and I think I need to change it again) so is it that they normally run with loads of lock on the inside wheel and I am just not able to reach the end points?

3. ANyone running one at mid west regional sunday that I can have a look at? Plus any spare spur gears!!
