Note: The following procedures require a press, suitable mandrels and tubing.
Removal
Upper reaction rod
1. Jack up the rear of the vehicle on the appropriate side and place it on supports placed under the chassis frame and rear axle assembly.
2. If necessary, remove the corresponding rear wheel.
3. Loosen the nut of the torque rod mounting bolt to the axle bracket. Try not to damage the brake lines.
4. Loosen the nut of the bolt securing the reaction rod to the chassis frame bracket.
5. Remove the bolts by knocking them out with a brass drift (support the bar while knocking out the bolts). The longitudinal reaction rod of the rear suspension with fastening parts is shown in the accompanying illustration.
1 - bolts; 2 - longitudinal reactive rod; 3 - nuts
6. Remove the torque rod from the vehicle.
7. Inspect the reaction rod for cracks and signs of deformation; replace if necessary.
8. Check the condition of the bushings in the reaction rod. Replace defective bushings:
- Support the rod under the bushing to be replaced with a piece of pipe of a suitable diameter (the sleeve should pass freely through the pipe).
- Using a tool whose mandrel rests against the outer steel tube of the bushing, press the bushing out of the rod.
- Wet the outside of the new bushing with soapy water and begin to gradually push the bushing into its seat using a piece of pipe that will rest against the outer steel tube of the bushing.
- Make sure the bushing is seated perpendicularly and is centrally located.
Lower longitudinal reaction rod
1. Jack up the rear of the vehicle on the appropriate side and place it on supports placed under the chassis frame and rear axle assembly.
2. Remove the corresponding rear wheel.
3. Loosen the nut of the bolt securing the reaction rod to the bridge bracket.
4. Loosen the nut of the bolt securing the reaction rod to the chassis frame bracket.
5. Remove the bolts by knocking them out with a brass drift (support the bar while knocking out the bolts).
6. Remove the reaction rod from the car, remembering its installation position - the ends of the rod are slightly offset.
7. Inspect the reaction rod for cracks and signs of deformation; replace if necessary.
8. Check the condition of the bushings in the reaction rod. Replace defective bushings:
- Support the rod under the bushing to be replaced with a piece of pipe of a suitable diameter (the sleeve should pass freely through the pipe).
- Using a tool whose mandrel rests against the outer steel tube of the bushing, press the bushing out of the rod.
- Wet the outside of the new bushing with soapy water and begin to gradually push the bushing into its seat using a piece of pipe that will rest against the outer steel tube of the bushing.
- Make sure the bushing is seated perpendicularly and is centrally located.
Installation
Installation is carried out in reverse order.
1. If the bushings have been replaced, carefully check the condition of the rod axle bolts. Replace any worn components.
2. Install the torque rod on the car, install the fasteners (nuts, washers and rubber bushings), but do not tighten it completely at this stage. Lower the car to the ground.
3. Rock the car several times to settle the suspension components, then tighten the nut securing the rod to the chassis frame with a force of 147÷177 Nm.
4. Tighten the nuts securing the rods to the bridge with a force of 98÷137 Nm.
