Torque specs axle nut and spindle knuckle bolts

Hi,

Pics 1 and 2 show the torque specs. Pic 1 is the axle nut and pic 2 is for the ball joints which I believe what you are referring to when you say steering knuckle.

I don't know if you need it, but here are the directions for replacing the axle. The remaining pictures correlate with the directions.

12. Remove the lower strut bolts and nuts using power tool. Refer to Exploded View FSU-13.
13. Remove steering knuckle from vehicle.

INSPECTION AFTER REMOVAL
Check for deformity, cracks and damage on each part, replace if necessary.

Ball Joint Inspection
Check for boot breakage, axial looseness, and torque of transverse link ball joint and repair as necessary.

INSTALLATION
Installation is in the reverse order of removal. Note the following:
Refer to "Removal and Installation" for tightening torques.

CAUTION: Do not reuse non-reusable parts.
