Inner Steering Rods



  1. Raise and support them front of the vehicle.
  2.  
  3. Matchmark the tie rod end to the steering rod.
  4.  
  5. Loosen the tie rod end locknut, then lightly retighten the locknut.
  6.  
  7. Position the steering rack so that whichever side is to be disassembled, the steering rack is as fully extended as possible.
  8.  
  9. Remove the pleated accordion boot from the steering rack housing and slide the boot up the steering rod toward the outer tie rod end.
  10.  
  11. Use a chisel to open up the lock plate, then loosen the ball socket from the steering rack using BMW Tool No. 32 2 100 or an equivalent tool by turning it counterclockwise.
  12.  
  13. The tie rod ends can be removed from the knuckle at this time, then as a unit, turn them counterclockwise to remove the inner tie rod end from the steering rack. Then remove the inner and outer tie rod ends from one another using a suitable vise, counting the number of revolutions it takes to release them from one another. This will help to retain a toe-in alignment base line for assembly.
  14.  
  15. Otherwise, rotate the inner ball socket counterclockwise to remove it from the steering rack. Then loosen the locknut and count the number of revolutions needed to remove the inner steering rod from the outer tie rod end.
  16.  

To install:

  1. Transfer the accordion pleated boot to the replacement inner steering rod, then transfer the outer tie rod end locknut.
  2.  
  3. Apply a light coating of an anti-seizing compound to the inner steering rod-to-outer tie rod end threads and thread the inner steering rod into the outer tie rod end the same number of revolutions as counted during removal. Then lightly tighten the outer tie rod end locknut.
  4.  
  5. Using a new locking washer, apply a thread locking agent to the steering rod ball socket-to-steering rack threads and tighten the steering rod to the rack using BMW Tool No. 32 2 100 or an equivalent tool. Tighten the tie rod joint to 54 ft. lbs. (75 Nm). The boss must fit into the groove on the rack. Use pliers to bend the lock plate over the flats on the nut.
  6.  
  7. Install the accordion pleated boot to the steering rack housing.
  8.  
  9. If removed, install the outer tie rod end using a locking nut. Tighten the nut to 23-29 ft. lbs. (33-40 Nm). Do not use a locknut on a tie rod that has a hole for a cotter pin. If originally equipped with a locknut, use a new locknut for installation.
  10.  


NOTE
If the tapered outer tie rod spindle rotates when assembling, seat the spindle by rapping on the ball socket with a soft faced hammer, or use a C-clamp or a pair of locking needle-nose pliers to press the two together.

  1. Tighten the tie rod end-to-inner steering rod locknut.
  2.  
  3. Have the alignment checked and adjusted as necessary.

  1. Raise and safely support the vehicle. Loosen the clamping bolt that retains the toe-in adjustment by keeping the tie rod end from turning in relation to the tie rod.
  2.  
  3. Remove the cotter pin and castellated or self-locking nut from the bottom of the tie rod end. Then, press the tie rod end out of the steering knuckle with the proper tool. Then, unscrew the tie rod end from the tie rod and remove it, counting the number of turns required.
  4.  

To install:

  1. Install in reverse order, using a new cotter pin or castellated nut. Recheck the front alignment and reset the toe-in, if necessary.
  2.  
  3. Torque the castellated or self-locking nut to 26 ft. lbs. (36 Nm) and the clamping screw to 10 ft. lbs. (14 Nm). Final torque the clamping bolt with the vehicle resting on its wheels.
  4.  

Outer
  1. Raise and support the front of the vehicle.
  2.  
  3. Matchmark the tie rod end to the steering rod.
  4.  
  5. Loosen the tie rod end locknut, and move the steering rod back and forth until it moves freely.
  6.  
  7. Loosen the tie rod end-to-spindle locknut, but do not fully remove.
  8.  
  9. Separate the tie rod end using a suitable tool, using the tool to press on the locknut to avoid damaging the threads.
  10.  
  11. Remove the locknut. If necessary, hold the spindle above the rubber boot.
  12.  
  13. Remove the tie rod end, turning it counterclockwise to remove it from the inner steering rod. Count the number of revolutions it takes to release the tie rod end from the inner steering rod. This will help to retain a toe-in alignment base line for assembly.

To install:

  1. Apply a light coating of an anti-seizing compound to the inner steering rod-to-outer tie rod end threads and thread the outer tie rod end onto the inner steering rod same number of revolutions as counted during removal. Then lightly tighten the outer tie rod end locknut.
  2.  
  3. Install the outer tie rod end using a locking nut. Tighten the nut to 23-29 ft. lbs. (33-40 Nm). Do not use a locknut on a tie rod that has a hole for a cotter pin. If originally equipped with a locknut, use a new locknut for installation.
