1999 ml 320 , right side steering arm is Loose 1/4 inch play , left side is fine . is this adjusable any help appreciated TIA....Bill.. upon further investigation it seems it is where the inner tie rod engages the steering rack, rubber boot is somewhat broken. When I grab the wheel I can move the tie rod in and out about a 1/4 or 3/8 of an inch.

 

replace both tie rods. I have to do the same thing on my 99 ML430...mine feels like your driving on ice.
