I'm getting mentally prepared to replace the thrust arms on my E34 535 (parts on their way from, whom else, bma). Two questions come to mind:

First, is the BMW ball joint puller available for rent from any of the major parts places? Has anyone had success using a generic puller?

Secondly, Bentley does not offer a torque spec for the nut on the ball joint for the thrust arm (perhaps I missed it?) but does mention 68 lbs-ft for the ball joint on the control arm. What should one torque to, 68?

Thanks for your input,
