Do NOT reuse the nut.
Notice: Do not hammer on the pitman arm, pitman arm shaft or puller. Damage to the pitman arm or steering gear may result.
Mark the Pitman arm (1) and the Pitman shaft in order to ensure the proper alignment at assembly.
Greetings and Welcome to Just answer.
First off, if you were only replacing the Pittman arm, then you did not need to remove the gear. All you needed to do was separate the Pittman arm from the relay rod, take the 3 bolts and move the steering gear. Because you were advised to take the gear out and not hold or secure the steering wheel, the intermediate shaft is out 1/2 turn and the steering wheel was rotated to the point the clock spring in the steering column has failed. You need to replace the clock spring and rotate the shaft 1/2 turn to correct this.
The gear should have 2 flat spots, maybe you separated the shaft up a bit higher? Near the fire wall?
It is nearly impossible to put the Pittman arm on wrong.
The clock spring you need to take the steering wheel off, remove the clock spring is right there. The steering needs to centered before installing a new one.
Then if there is no way the steering wheel is out, then the pitman arm is not perfect and is the cause of it being out.
No the steering wheel is master splined. THis steering gear, was it straight before you pulled it out?
What brand of pitman arm did you buy?
Ok, I was not understanding that you had replaced the steering gear as well. In that case, the I would suspect the unit was assembled wrong.
