Hi David- aka steering wheel slop

I've had the steering linkage tightented up (inside the steering box & steering wheel centered) on the E320 Coupe twice in the last 40K miles by factory authorized service - - and the results are nothing less than , "as new"

fyi-currently there is negligible play in the steering - if any at all & I've had a lower control arm replaced to maintain the suspension 100% within the last 40K miles as well

let us know what turns out

tks-fad
