Hi there,
Why would you have the servotronic. In my experience the none servotronic is much better in terms of feel for the road and the front wheels. Although the servotronic feature controls the amount of fluid pussed through the steering box depending on speed, in practice it feels to light for me. I just replaced mine for a complete revised NONE servotronic box from hydroline. See URL
Hydroline Powersteering BV, Kwaliteit Stuurhuis Revisie
These guys do not only replace the seals but comepletly revice the internals of the box using shimmingplates to minimize all sorts of play. somebody on the forum, forgot his name, already has one of hydroline and tested it on the ring. He was over enthousiastic about it.
Hydronline has one on the shelf WITH servotronic I belief. I know this because I had contact with them a couple of weeks back about mine.
Give them a call. They know all about the E34 M5 box with the short ratio compared to the standard E34 box.
My advise, for what it's worth
leave the servotronic for what it is and GO for the NONE.
I forgot to mention: Stealers price is around: 1100 euros. Hydroline 450......there you GO!
Cheers

Ginger, I might be interested in your servotronic box together with the control module. Sorry to know the reason why you will sell it. Hope the paperwork does not take too long. Is there much play in your steering box? I mean would it be recomendable to send it fot revision before mounting it in the car?
Crash&Burn, the reason why I prefer servotronic is because the non version is too heavy for me when parking the car. I would prefer something "lighter" like the one I have in the 740i. Thanks for the link

Just got the car back with a completely revised steeringbox ex serv. Paralell to do that a CH11S flush. Steering has much much improved and I think cause of the new fluid, the steering is not heavy at all. So.........
@Robinson: Unless you like to park and unpark the car all the time, please reconsider this...Especially with a used servobox. A normal (revised) one with new Pentosin does miracles....

Adding to this some easy checks to exclude other forms of play.
1) Check the steeringcolumn nut between the pedals. This can come loose. Don't overtighten it because you won't be able the axial move the column. Hand tight with 20 degrees extra should be enough.
2) Pitman arm: When mounting the pitmanarm make sure there is at least 1,5 mm space between the face of the pitmanarm and the face of the steeringbox. Reason is: When turning the wheel the outgoing steeringbox ax is slightly pulled. If the pitmanarm is too close to the box, the faces will rubb against eachother. This in itself is not that bad but the increased force needed on the box for the pitmanarm to move wil cause an increased sense of play when sterring the car.
3) when flushing the fluid make sure the filter in the reservoir is thoroughly cleand. You can ONLY do this by removing the reservoir and flush upside down with brakecleaner or something. You cannot buy the filter alone so it's either cleaning or e new reservoir. And they are kinda expensive for just a reservoir

Thanks for your advices Crash, All these points were already checked time ago. When I move the steering wheel to one and other direction I can see how the input shaft turns but there's not any output from the box so the play must be there.
