I believe that Stretch has done first, second and third from reading the post through.
As Build pointed out, something else is wrong, bent or just wrong part and with Stretch's old box he had an extra 1/4 turn on one side. Fourth is the likely problem and it seems to have existed before the new box was installed. If nothing is bent then at some point in time wrong part(s) were installed if adjustment cannot be made without changing the first, second or third. If all other parts are in good condition, Moog makes many lengths of adjuster sleeves. If your coming up short on one side this is the easiest and safest fix; Edited by Trader - Aug/16/2018 at 8:12am |

Stretch, hoping you can tell me what you found. I have exactly the same problem you described in your first post. Have two AMX's both a little over 4 turns lock to lock. ( Full lock in this case is hitting on the lower control arm stop before gearbox travel limit ). Project AMX I am working on now is a little over 3 turns lock to lock. ( Full lock here is end of travel in the steering gearbox and hitting lower control arm stop about the same time ). As you said one tie rod right out one up tight. Same saginaw #7800746 steering gearbox in all three cars. The one in the project car doing one less turn lock to lock has an "F" stamped on the pitman shaft cover. Am thinking it may have been rebuilt sometime. Something different about that box. Doesn't leak at all and not wanting to pull it apart. |

Was the splined upper sector disconnected at some point?. If so its easy to get those splines off by a few as there is no keyway to prevent it going on wrong but there is a pin that fits against a flat that is hard to get just right once you take it apart. Had that problem in my car after I replaced the couplings and box. Was off by about the same as yours. You have to pull the box back out to correct unfortunate as there isnt enough room to tap out the upper sector. I was able to get mine very close after I did this

There's a fairly standard procedure for putting in new steering boxes, or work that affects steering wheel centering. I've done all the short cuts and they don't work :-)

Huh, the manual Saginaw box in my 68 american and the Gemmer in the 61 both have a funny spline so that they only go on in one position. I'm fairly sure, now you're making me wonder! But yeah in general, the steerping box, column (if applicable), steering wheel need to be centered before the linkage is mounted so you have a reference for adjusting tie rods to center steering.

Researching the subject I found saginaw offered different ratio steering boxes.
Then looking on APD I noticed " remanufactured steering gear, quick ratio, 3 turns lock to lock " is listed. Think this AMX has this quick ratio cos without the pitman arm fitted the steering wheel has 3 turns lock to lock. With the pitman arm and steering linkage fitted, same three turns goes from one lower control arm stop to the other. I changed the pitman arm and got the tie rods almost even, steers well. 3 turns of the wheel instead of 4 seemed a problem at first, now looks good.
