The shims are round and they go beetween the inner tie rod and the rack. Im not 100% sure or not if they are shims or some sort of lock washers. When I pulled the boots off is when I noticed I had a minor amount of fluid in their. I used saftey wire and Gasket crap but they seem to leak worse...now on my exhaust. My old boots pop. I was thinking of putting a vent in them but they didnt have one before and they never popped then so the next logical step would be to replace the brittle noise makers. When at a dealer they do the ends and the boots.
Oh yea and blue loctite never hurts
