190E sloppy steering question

I have a 1985 190E 2.3 with 168,000 miles on it.
The steering has felt a little loose for a while but I just put new
tires on it and now it is impossible to drive on the hiway.
It jumps right and left like there is a huge amount of play in the steering.
My question is this, I understand that the steering box is adjustable to take play out of the steering but there is no instructions in my Chilton manual, can someone explain how I would do this??
Question 2, how hard is it to rebuild the idler arm, I'm guessing that by now it needs a rebuild!!

Thanks in advace for any suggestions!!

A common problem on the all applicable Mercedes is the Idler arm bushing failure. Over time they just wear out.

Also, pick up a steering dampner & a drag link. You should be able to buy an aftermarket draglink for around $50 & the dampner should run you no more than $35.

Oh yeah, the idler arm bushing replacement kit is pretty inexpensive as well. It is a project that you could handle in about 2 hours w/ a couple of 17mm wrenches & sockets !!

Thanks Pat,

I did change out the damper because I had checked it and it basically wasn't doing anything! I will get a Idler arm kit and a drag link from MB.
Hard to find aftermarket stuff in Canada!

Sure appreciate the help!!!!
