OK,
I had my first go at replacing the thrust and control arms on my '94
540iA this evening. The balljoints on the control arms are gonzo and the thrust arm bushings are shot (60 mph braking shimmy) so I figured I'd replace both arms (on both sides obviously) and refresh the front suspension. With 115k miles on them they don't owe me anything.So anyway, everything looks fairly straight forward *except*... How the heck are you supposed to remove the Bolt and Nut at the bushing end of the Thrust arms? The bolt head is easily accesable, but there is no way I can get any kind of wrench on the nut end. It's wedged in behind and between the round section cross-member and frame so tightly that I can't even get an open end wrench on it to hold it and try to spin the bolt, though that would be a less than desireable method.
Anyone done these on a 540 before? I'm guessing from the descriptions I've read online and in my Bentley that there is more clearance in that area on the 6 cylinder models or in other years. They don't mention doing anything fancy or having to remove anyuthing to gain access to the nut.
The only thing I can see doing is removing the sway bar mount bracket and moving the bracket and sway bar down and out of the way? Of course that bolt would not budge for me and I don't have an impact wrench (yet), but that may be my next purchase... ;-)
TIA,
