Assembly 

1.

Apply anti-seize compound to the threads in the adjusting sleeve.

2.

Thread the two tie rod ends into the adjusting sleeve, turning them the same number of revolutions that were required for
removal.

Installation 

1.

Secure the tie rod to the center link with the slotted nut and tighten to 63-77 lb-ft (85-104 N•m).

2.

Secure the tie rod to the geared hub with the washer and slotted nut. Tighten the slotted nut to 63-77 lb-ft (85-104 N•m).

3.

Install a cotter pin in each slotted nut. If necessary, tighten the slotted nuts to align the holes for cotter pin insertion. DO NOT
back off the slotted nuts to align the cotter pin holes.

CAUTION:  Ensure that the outboard clamp faces the halfshaft and the inboard clamp faces away from the stabilizer bar (front
only) or damage to equipment may result.

4.

Before final tightening of the sleeve clamp hardware, center both tie rod end studs in their sockets(Figure  8-7).

CAUTION: If the stud and socket are not properly aligned, a partial or complete lockout of stud swing could result. Limiting stud
swing can increase component wear and a complete lockout can cause component damage.

5.

Lubricate the tie rod ends.

6.

Lower the vehicle and align the toe-in. 

CAUTION: The sleeve clamps must be positioned between 3/16" and 5/16" from the end of the sleeve and the bolt and nut tight-
ened to 30 lb-ft (41 N•m).

7.

Align the sleeve clamps and tighten the bolt and nut assemblies to 30 lb-ft (41 N•m)(Figure  8-10).
