You re-use your thrust washers with an Aussie locker. As long as they aren't in bad shape.

In my build thread I have a link to someone else's install that I used in conjunction with the paper they send you.

 

Well I pulled it out again and reinstalled it and checked all tolerances again, everything was within spec. I took it down the road and still had the same issue, so I pulled it out and put the spider gears back in. I had checked the tire pressure before to make sure it was the same, but I started thinking after I put the spiders back that I should have checked the tire circumfrence the tires only have 1500 miles on them but they are treadwrights, sure enough there's a 3/4 diffrence between the two back tires so Im guessing this was causeing the problem because the tires are turning at two diffrent speeds. When I get more time I'll measure all of my tires and see if two are the same then put them on the back and put the locker back in and see what happens, If I don't have two the same I'll have to wait untill I can save up for some diffrent tires, although I really like the treadwrights they might not be locker freindly.
