Features of the rear suspension of a Nissan Almera car

Rear suspension semi-independent with an elastic beam, spring with double-acting telescopic gas-filled shock absorbers.

Brackets for spring support are welded to the beam and levers.

To increase lateral stability and reduce roll angles, a stabilizer bar is installed inside the beam, the ends of which are welded to the lever amplifiers.

Flanges are welded to the suspension arms for mounting the axles of the rear wheels and the shields of the brake mechanisms.

Front, the levers are equipped with welded bushings with silent blocks pressed into them.

The outer sleeve of the silent block is plastic, and the inner sleeve is metal.

The rubber mass of the silent block, vulcanized to the bushings, is asymmetrical in cross section.

Therefore, when pressing the silent block into the lever, it must be strictly oriented.

The elastic elements of the suspension are coil springs.

The spring rests through rubber gaskets: from below - on the arm bracket and from above - on a support welded to the side member of the body.

The lower coil of the spring has a smaller diameter.

Rear suspension springs are divided into classes according to stiffness.

Spring class is marked with paint. Springs of the same class must be installed on the right and left sides of the car.

When replacing, it is recommended to install springs of the same class that were installed on the car.

A rubber-metal hinge is pressed into the lower eye of the shock absorber, through the central bushing of which a bolt passes, securing the shock absorber to the suspension arm.

The shock absorber rod is attached to the body through two rubber pads (one at the bottom of the support, the other at the top) and two metal washers.

A spacer sleeve is installed between the cushions on the damper rod, which prevents the cushions from being excessively deformed when the stem nut is tightened.

The shock absorber is fitted with a compression stroke buffer to which the boot is attached.

Double-row rear wheel bearings.

The role of the rear wheel hub is performed by the brake drum, in the hole which the outer ring of the bearing is installed with an interference fit.

The inner rings of the bearing are mounted on the trunnion (axle) of the rear wheel with a small gap.

In the drum, the bearing is fixed with a retaining ring.

During operation, the bearing does not require relubrication.

The installation angles of the rear wheels are specified by the beam geometry and cannot be adjusted in operation.

Angles can only be checked on a special stand and compared with control values.

If the values of the rear wheel alignment angles do not correspond to the control values, it is necessary to check the condition of the rear suspension elements.

Possible malfunctions of the rear suspension and solutions

- Cause of malfunction

Remedy

Noise and knock in the suspension when the car is moving:

- Faulty shock absorber

Replace shock absorber

- Weakening of the shock absorber mounting or wear of the bushing of the shock absorber lugs

Tighten the lower shock mount bolt and nut or replace the bushings

- Wear of silent blocks of longitudinal suspension arms

Replace silent blocks

- Settlement or breakage of a spring

Replace the spring

- Wheel bearing failure

Replace bearing

Moving the car away from straight ahead:

- Unequal tire pressure

Set your tires to the correct pressure

- Wheel tires have different wear or tread pattern

Change tires

- Violated camber

Remove the cause of the camber failure

- Settlement or breakage of one of the springs

Replace the spring

- Deformation of trailing arms

Replace silent blocks

Increased or excessive tire tread wear:

- The air pressure in the tires is not correct

Set normal pressure

- Violated wheel settings

Remove the causes of incorrect wheel alignment

- Vehicle overload

Do not overload the car

- Wheel imbalance

Balance the wheels
