Alos, if you can, take a look at my questions 2 & 3 above regarding shims & tool drivers

I am not sure what you mean by a "tool driver". You can use a seal driver, but I find a block of wood and a mallet to suffice to install the wheel seal.

As for shims, again. Not quite sure. I assum you mean the ones that go on the ends of the axles. You don't "need" shims, but you do need to put whatever ones that were on there, back.
