Then I'm waaaaaaaaay out of spec, grabbed a helper and measured it to about 5mm wiggle on the wheels outer perimeter which translates to about 3 mm on the idler arm.
This is achived with very moderate force and the same done on the drivers side produces no visible play whatsoever.
Like the cheap doitallbymyself type I am I'm gonna turn me some new bushings in teflon with the inner sleeve from the old ones as the base at work tomorrow.
I'll report back with my experimental results.:p
