Steering wheel not straight after steering box replacement

Recommended Posts

Hi all,

I replaced my steering box yesterday for the 2nd time this year (first box was still loose), I followed the same procedures as the 1st time except this time I had to remove the drag link from the pitman arm and remove the pitman arm from the steering box with the steering box removed from the vehicle, long story...I couldn't get the pitman arm puller on because the pitman arm was too close to steering gear and the puller wouldn't fit...had to use some persuasion in the form of a BFH (big freakin' hammer).

So after a little persuasion I got the pitman arm off and everything reassembled. it all went together just fine except now my steering wheel points to about 1:30 when going straight down the road. I did not have this problem last time and am sure all the correct placement of notches was made (steering shaft to steering gear & steering gear to pitman arm) could this be an issue with the steering box not being straight or is it just an issue for the alignment shop? (I just had it aligned...three times as a matter of fact, once after getting new tires, second time after camber sleeve installed, third after new axle pivot bushings installed...so I know alignment was good before the steering gear swap).

Thanks for any help

Yo T,

Before touching anything underneath, did you turn steering wheel so tires line up straight, then secured steering wheel with tires still line up straight?

Hi miesk5,

Yes everything was lined up straight and locked during disassembly and reassembly. All notches lined up same as they did the first time. Only big difference this time was I had to take drag link off pitman arm.

Hi miesk5,

Thanks for the info,

Wondering if it's possible that something in the steering gear, steering shaft or column got bent when torquing pitman arm nut (torqued to 210ftlbs haynes spec said 190-230ftlbs)?

Thanks again for your help

Yo t,

Following by Ford;

"Recheck torque readings and replace the steering gear sector shaft arm. Tighten the pitman arm-to-sector shaft nut 230-310 Nm (170-228 lb-ft)." In a 96, but same for your 95.

Hi miesk5,

Is it ok to torque that when in the vehicle? Or should that be done off the vehicle?

Thanks again

Yo T,

Sorry, we have a bad comcast connection.

In-Vehicle Adjustment

SPECIAL SERVICE TOOL(S) REQUIRED
Description Tool Number
Pitman Arm Puller T64P-3590-F

Adjust total on center load to eliminate excessive lash between the sector and rack teeth as follows.

  1. With the engine (6007) off, turn the steering wheel (3600) from full right stop to full left stop at least once.

  1. Refer to Section 11-04 for proper steering wheel hub cover removal procedure.

  1. Disconnect the steering gear sector shaft arm (3590) from the steering gear sector shaft (3575) using Pitman Arm Puller T64P-3590-F.

  1. Attach a newton meter (pound-inch) torque wrench to the steering wheel hub nut and determine the torque required to rotate the power steering gear input shaft and control (3D517) back and forth across the center position (± 90 degrees).

  1. Reset the meshload only if the measured torque for total on-center load is less than 1.5 Nm (13 lb-in). If reset is required, loosen the adjuster lock nut and turn the sector shaft adjuster screw until the measured total on-center load torque is 2.0 Nm (18 lb-in). Hold the sector shaft screw in place and tighten the lock nut to 48-61 Nm (35-45 lb-ft).

  1. Recheck torque readings and replace the steering gear sector shaft arm. Tighten the pitman arm-to-sector shaft nut 230-310 Nm (170-228 lb-ft).

  1. Verify no binding condition in steering throughout full stop-to-stop travel. Verify customer concern is resolved.

  1. Replace steering wheel hub cover.
