400E slack spot in steering
 

I was turning my wheel the other day and my friend spotted a point in the steering where there is a dead spot, about 2-3 inch slack back and forth at a certain point both directions where the wheels don't move. not sure where I should start.

Inspect all the tie rods, pitman and idler arm, and the whole steering setup in general. If you don't find the slop there, it'll be the steering gear, or the steering column flex discs.

If somebody drove the car for any length of time with a front end vibration, chances are the steering gear is worn out. Seems to happen pretty quick from what I've seen.

I'd bet it's the gearbox, but it's easy enough to check the rest of the "stuff" first.

FYI, if you need a steering gearbox, make sure it was a rebuilt from "C&M Hydraulics". Chris completely disassembles the box and his crew puts them back together right.

No affiliation, etc., he's just a good guy.

Where is the slack spot, in a turn or going straight?

Could be an alignment issue.

while the wheel is turned

Off center there will be more play than at center, 2" to 3" inches seems like too much. Thanks for the "plug" Mike.

Does this much play require a new box or a rebuild?

If there is that much play off center, I suspect there is too much at center. If the box has not been "rebuilt" by someone else, you might try a pitman shaft adjustment however I don't think it will help much. If the play is that much and in the box it will need to be replaced.

I drove the car today and you can't feel the slack spot when driving as you can while stopped. Steering tighens up a little at slow speed as well

When the car is stopped, engine running or not, it is normal for the steering wheel to move 1 1/2" to 2", if you move the steering wheel and watch for the tires to move. You are moving the reaction valve inside the gearbox, that is normal. To check for play, following how MBZ says to do it reqiures too much feel, when is the valve moving or is it play. I think the best way is to drive the car, if it feels normal when driving I would not worry about it. If you have any questions feel free to call. 702.734.8090

I see the steering fluid is leaking from some where. I replaced the seal to the ps fluid top but it still seems to be leaking although not as much. I was wondering if the is a way to drain & clean the system before addind new fluid?? Thanks for the input from the masses!!!

No drain - you just suck out the resovoir fluid and change the filter.

Common leak points:

Front seal and o-ring
resovoir at the bottom
return (lower pressure) hose.

Clean everything well and see where your leak is. george said dusting the area with talc powder after cleaning.. helps make the leak show up clearer.

Best of luck..

Might add on the original note-

With the wheel turned, there will be lots of play. You need to check play with the steering box centered. I think the manual says about 1 inch of slop on center is acceptable.

Sucked out the resovoir today that stuff looked 17 years old added fresh fluid did not have the filter. I will do it again when I get the filter
