I own a Gen X, and have 1 question. in the manual for building the dif it doesnt show a thrust bearing being used, but the car i have does have one.

Can someone explain what the difference is in running one. I've been running with it since i got it, but now i want to try it without, will I be sorry, or should i try it? Is there an advantage to running it?

Also are the washers that go on either side of the thrust bearing supposed to be smooth or have a grove in it?

thanks
