That adjustment is for the later box. It's the control valve on top of the box. When properly adjusted the car will NOT self steer with the wheels off the ground. If it is off, the wheel will steer by itself to the side that it is off. Alignment and end play have the effect on self centering. If the adjustment is cranked down to hard in a miss guided attempt to get rid of steering wheel play, you will have to steer the car back to center all the time and it will wander all over because the wheel stays wherever it's pointed. Not enough positive caster will also affect self centering. I'm only familiar enough with the early steering box to see that it's more complicated and less forgiving than the 58 and up style.

Assuming alignment is correct, (caster specifically) and you have the front wheels off the ground and started the car, I believe if set up correctly, hydraulic pressure would return the wheels to straight. I'll try to dig up more info if I can.

After a long winter of replace/repair the last item to do is the power steering. I need advice on the following problem. Vehicle, when purchased, had a "off center" steering problem, i.e., turned left OK but when turning right there's a definite "catch" and car wanted to remain turning right, as if jammed. It appeared to be, and felt like a mechanical bind in the steering box. All suspension parts checked out OK, no binds or problems. I had another steering column that came with the car so we swapped out the column. Car runs and drives great however doesn't return to neutral, i.e., if turning left, wants to stay left, same if turning right. There isn't the "catch" like in original column but obviously has a problem. Any ideas on verifying where the problem actually may be? If needing rebuilding is their a vendor to be recommended? I know the coaxial steering gear is not something all will handle. Any idea of cost to get rebuilt? Thank You Kindly Jim Ashenmacher 300B [Non-text portions of this message have been removed] [Non-text portions of this message have been removed] [Non-text portions of this message have been removed] [Non-text portions of this message have been removed] ------------------------------------ To send a message to this group, send an email to: Chrysler300@xxxxxxxxxxxxxxx To unsubscribe from this group, send an email to bob@xxxxxxxxxxxxx or go to http://autos.groups.yahoo.com/group/Chrysler300/join and select the "Leave Group" button For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm For archives go to http://www.forwardlook.net/300-archive/search.htm#querylangYahoo!
