Is steering box shaft indexed? - PeachParts Mercedes-Benz Forum

I just took the steering box off my 81 300SD parts car to put on my 85 300SD. Unfortunately I didn't pay attention to the position of the steering wheel as I ASSUMED that the splines on the shaft were indexed. After I had the box off and cleaned up it appears that this is not the case. Any suggestions on putting the box back on properly, or am I just blind and the splines are actually indexed to the steering arm?

There is a lock nut in the bottom. Search around for alignment and youll see the bolt needed.

if this is the pitman arm?

There is an alignment groove on the arm face and output shaft end...

If the steering wheel is not level:
Note:
Wheels straight, full vehicle weight on the tires.

#1. Remove the flex joint pinch bolt (at the gearbox).
#2. Insert a screwdriver in the pinch slot, and carefully drive it in to spread.
#3. (engine off), Grab the steering wheel and force it to center ignore the ratcheting feel/noise = slipping across the splines.
#4. If the screwdriver slips out to soon = you may need to repeat.
#5. Remove the screwdriver.
#6. Install and tighten the flex joint pinch bolt (at the gearbox).
#7. Test drive.

Thanks! Did the r and r today and all went smooth after I found the mark on the end of the shaft and on the pitman arm. Seems like all other steering boxes I have done in the past had a flat to index the arm, but it's been a while. I don't know why I put it off for so long- it was a fairly simple deal and only took 1.5 hours in my dirt driveway with handtools.
