Removing
Details of fastening of a spring of a forward suspension bracket
1 - bolt; 2 - bushing; 3 - nut; 4 - U-shaped bolts of the ladder; 5 - leaf springs; 6 - earring plate; 7 - plate; 8 - ladder support plate; 9 - washers
1. Jack up the front of the car and place it on jack stands under the frame.
2. Install the jack in the center of the front axle housing and cock it, removing the load from the shock absorbers.
3. Disconnect the lower shock absorber support from the spring ladder plate, push the shock absorber up, moving it away from the axle housing.
4. Lower axle by removing weight from springs, loosen ladder U-bolt nuts and remove skid plate.
5. Turn away fixing nuts and remove fingers and plates of an earring from the forward end of a spring.
6. Give a nut and a bolt of fastening of an anchor finger from the back end of a spring. Remove the pin and remove the spring from under the car.
7. Use a wire brush to remove all dirt and corrosion from the leaf springs. Inspect the leaf springs for cracks and dents. Check the tightness of the central bolt.
8. Check the rubber bushings, clevis pins, anchor pin and travel stop for signs of wear and damage. Replace defective components.
Note. The compilers of this Guide recommend in all cases to replace the suspension springs in pairs, even if only one of them is faulty.
Installation
Installation is in the reverse order.
1. Do not tighten the ladder U-bolt nuts to more than 118 Nm, as this may deform the spring against the axle seat brackets or shear off the U-bolts. Tighten the nuts with the required force evenly, in several stages and make sure that the base plate is in the correct position.
2. Do not tighten the nuts securing the clevis, anchor pin, and lower shock absorber support until the entire weight of the vehicle is transferred to its wheels. This will help avoid excessive stress on the rubber bushings when they move into the working position.
Replacing the anchor pin for fastening the rear end of the spring and its bushings
Note. Replacing the rubber bushings of the anchor pins of the front suspension springs can be done without removing the springs from the vehicle.
1. Jack up the front of the vehicle and place it on jack stands under the chassis frame.
2. Install the jack in the center of the front axle housing and cock it by hanging the front axle and spring assemblies.
3. Give fasteners (bolt with nut) anchor pin from the rear end of the spring.
4. Remove the rubber bushings from the spring.
Installation is in the reverse order.
1. Lubricate the bushings with rubber lubricant beforehand.
2. Tighten the anchor pin fastening nut with a force of 76÷102 Nm, and the fixing bolt with a force of 11÷15 Nm, after the weight of the vehicle has been transferred to its wheels.
Attention! The final tightening of all fasteners with the required force must be carried out after the weight of the car is transferred to the wheels, otherwise the bushings will be subjected to excessive loads during the operation of the car.
Replacement of plugs of an earring of a spring
Note. The rubber bushings of the front suspension springs can be replaced without removing the springs from the vehicle.
1. Jack up the front of the vehicle and place it on jack stands under the chassis frame.
2. Install the jack in the center of the front axle housing and cock it by hanging the front axle and spring assemblies.
3. Give the fixing nuts and remove the earring assembly from the front end of the spring and suspension bracket.
4. Remove the rubber bushings from the spring.
5. Installation is carried out in the reverse order.
6. Lubricate the bushings with rubber lubricant beforehand.
7. Torque tighten the fixing nuts.
Note. If you cannot properly align the clevis assembly bolts with the holes in the spring and hanger bracket bushings, insert a block of wood between the spring and chassis beam, then jack up the end of the spring until the components align properly.
Attention! The final tightening of all fasteners with the required force must be carried out after the weight of the car is transferred to the wheels, otherwise the bushings will be subjected to excessive loads during the operation of the car.
