Looking to put new suspension parts in today and am confused by ball joint nut torque specs.

Our FSM says Upper at 135 ft / lb and lower at 135 or 175 ft lb depending on bolt size. However, the two sizes listed are not the size of the bolts on these new ball joints.

The new ball joints both upper and lower are 15/16 wrench size on nut which makes the bolt part a 5/8" fine thread.

The general torque specs in the front of our FSM say 160 ft lb for 5/8 fine thread. If I went by those then the upper would be 160 and not 135.

I'd go with the 160ft/lbs general prescription.
