What are the torque specs for the front strut-to-knuckle bolts?

49 - 59 N·m (5.0 - 6.0 kg-m, 36 - 43 ft-lb) to the knuckle.

What torque is used for the transverse link (lower control arm) fasteners?

88 - 108 N·m (9.0 - 11.0 kg-m, 65 - 80 ft-lb) and 98 - 118 N·m (10.0 - 12.0 kg-m, 72 - 87 ft-lb). Final tightening should be carried out at curb weight with tires on the ground.

Can the strut assembly be disassembled or repaired?

No — the strut assembly is a non-disassemble type. If oil leakage occurs on the welded and gland packing portion, or if the piston rod or threads show cracks, deformation or other damage, replace the strut assembly.

How is the coil spring removed from the strut?

Compress the spring with a coil spring compressor (special tools HT71730000 and ST35652001) just enough to permit turning the strut mounting insulator by hand.

Should the cotter pin be reused?

No — the cotter pin should always be replaced once it has been removed.

This is page FA-11 from a Nissan factory service manual section titled "Front Suspension," covering the spring and strut assembly. The top half shows an exploded parts diagram of the front strut and transverse link (lower control arm) assembly, identifying components such as the coil spring, non-disassemble type strut assembly, strut mounting insulator case, strut mounting insulator, strut insulator bracket, dust seal, thrust seat, spring seat, bound bumper rubber, dust cover, and cotter pin (which must always be replaced once removed). Torque specifications in N·m (kg-m, ft-lb) are given for major fasteners: strut top nut 25-30, mounting nuts 31-42, strut-to-knuckle bolts 49-59, transverse link 88-108 and 98-118, and 36-47 for another fastener. A caution warns against damaging the piston rod during disassembly/assembly, and a note states the transverse link's final tightening should be done at curb weight with tires on the ground. The lower half covers disassembly (compressing the spring with special tools HT71730000 and ST35652001) and inspection procedures for the strut assembly (oil leakage, piston rod cracks, thread damage), strut mounting insulator (rubber bushing condition), and thrust seat, each requiring replacement if damaged.
