  Q: How to Service and Repair the Rack and Pinion Manual Steering Gear on Chevrolet Metro?

  A:

  Start Rack And Pinion repair by extracting the component from the vehicle then making a notation of the outer tie rod end locknut placement on the inner tie rod threads. You must loosen the outer two tie rod end locknuts before taking off the two outer tie rod ends from the inner rod connections. Start by removing first the retaining clamps (1,2) and boots from the inner tie rods before unstaking the ball nut to extract the inner tie rods from the rack. Proper cleaning solution dissolves all steering Rack And Pinion parts before removing the pinion seal. Use pinion socket (J34871-A) to check the condition of the pinion oil seal before inspecting steering rack boots for wear or deterioration or tears and planning for replacements if needed. Check the dust seal for wear like the other components and replace it if damage occurs. Use a torque wrench to determine the pinion's rotational strength. Measure the torque of the pinion using a torque wrench which should fall within 1.0 - 1.58 nm (9.0 - 12.96 inch lbs.). Rack And Pinion replacement is necessary when the resistance measurement exceeds specification. Dust seal replacement necessitates inside application of chassis grease gm p/n 12377985 followed by ball stud installation. Fit two new inner tie rods to the rack by torquing ball nuts to 70 nm (51 ft. Lbs.) while using the staking tool to create 24 mm (0.95 inch) flat spot separation. The inside of each outer boot requires Rack And Pinion lubricant gm p/n 1052182 or equivalent before the boots should be placed on the steering rack housing grooves and inner tie rods. Secure the outer boot clamps. Use the service boot clamp installer (J22610) to secure new inner boot clamps while maintaining proper boot orientation and secure fasteners. The marked position on the new inner tie rod will receive measurements taken from the previous inner rod. Next place the outer rod end locknuts to these marks on the inner rod thread before attaching outer rod ends to inner rods and reinstalling the Rack And Pinion device in the vehicle.

  Q: How to Replace the Front Rack and Pinion Steering Gear on Chevrolet Metro?

  A:

  In order to replace the Rack And Pinion, pull back the front part of the driver side floor carpet and remove the steering shaft coupling cover. Loosen (but don't remove) the bolt which retains the upper steering shaft coupling as well as the bolt that retains the lower coupling of the steering shaft to remove the shaft from the pinion. Lift and support the vehicle while removing the front tire and wheel assemblies. Remove the cotter pin and the castle nut from each outer tie rod. Put on the tie rod end remover (J21687-02) and disconnect the outer tie rods from the steering plates. To take off the Rack And Pinion from the bulkhead, you need to get rid of the 4 bolts and the 2 Rack And Pinion mounting brackets and get the Rack And Pinion off through the front wheel opening. For the installment, position the Rack And Pinion towards the back in the vehicle through the front wheel on and attach the 2 mounting brackets on the Rack And Pinion. Secure the Rack And Pinion to the bulkhead using the 4 bolts mounted to the mounting brackets, which should not be overtightened more than 25 nm (18 ft. Lbs.). Reattach the outer tie rods to Steering Knuckles without loosening the castle nuts to install the cotter pins. Put in the castle nuts on the outer tie rods, tighten them to 43 nm (32 ft. Lbs.) while keeping the cotter pin slotted position against the ball stud slot and it should not be turned over 1/6 a turn from the tightening specification. Fit new cotter pins to hold the castle nuts by bending the end of the pins. Replace the front tire and wheel assemblies, lower the vehicle, and link the pinion shaft to the steering shaft coupling. Secure the pinion shaft to the lower steering shaft coupling with the bolt, tighten it to 25 nm (18 ft. Lbs.), and then hook the bolt on the upper steering shaft coupling to the same specification. Finally, you may install the steering shaft coupling cover and right back reposition the driver's side floor carpet.
