I'll try and be thorough with this. The SX is an absolutely awesome machine so please do not let such a minor hicup tarnish your opinions of it.
The outdrives are strong for the purpose, when they are weak is if something catch's - such as the bone into the slot, or a stone caught in there. So they don't have that added strength to cope with this additional strain.
So do take care with setups. What can cause the additional strain is:
- Too much camber change, raise internal ballstud/use a longer turnbuckle position
- Too much up travel, use external shock limiting of around 2-3mm
- Too much driveshaft plunge, go to diff high position.
If you do break an outdrive, feel free to post on here but I do strongly recommend that you contact Schumacher, take photos, write out a setup sheet. This will help Schumacher in their findings, it is being looked at.
Personally, I have broken 1 on the rear using the manual setup. So to prevent any further I have done the following things: (which also results in a far better setup)
Trimmed the top off the front castor blocks, lowering the outer ballstud.
Remove all spacing from front inside ballstud, raising the inner ballstud.
(Together gives far less camber change, and more progressive steering)
Gone to shortest inboard rear CF bracket, with 4mm ballstud.
Outer hole on hub, with 60mm turnbuckle (longest posible link)
(This gives linear camber change throughout suspension travel).
Limited all four shocks externally by 3mm
Gone to rear diff to high position, set the belt 1 setting looser than manual.
(This will reduce driveshaft plunge, increases traction)
If anybody wants to PM me or any other Schumacher team driver, please do, I'll always put 100% into helping anybody.
