    Best bet is to download the instructions and guide from truvativ.

    oder does not matter.

    use the correct spacers, simple really.

    so you have not read the instructions!

    sounds like you will have killed the bearings UNLESS you have a 73mm bb shell. but if you have a 73mm bb shell the axle will move.

    for a 68mm shell with a standard chain device you need one spacer each side.

    (But If you device is 5mm thick then you are OK).

    chain device is 5mm thick,there abouts,if i put spacer on the driveside there wouldnt be enough axle to fit the arm/chainring,the axle does not move side to side,all feels very tight etc
