New tires yesterday and shop says my Idler Arm needs a repair kit prior to aligning. We're under a 1992 400E, 215k miles - probalby time. Looks pretty straight forward, but any tricks to this? Breaking the nut free looks like it may be "fun", given the space provided, no rust however. Given that that's achieved:

- Is dis-assembly and reassembly best done with the wheels grounded or in the air? I'm thinking minimal tension on everything would be best/essential.

- How about bushing removal, given I do not have the MB special tools suggested in the shop manual?

Any experience out there much appreciated. Scott
