One of the unusual suspension solutions is the control arm link in BMW 5 Series (E39, E60, E61), 6 (E63, E64), 7 (E38, E65, E66, E67), X5 (E53), Z8 (E52). The link consists of 2 metal-rubber bushings, one of which has an additional element attached in the form of a metal rod. In the case of replacing standard bushings with polyurethane ones, this original rod should be used. The polyurethane set consists of 2 elements: an external metal sleeve and a polyurethane element.
The instructions below show you how to properly replace this element.
