The maintenance of the suspension system is mainly to check the installation and function of each component, and the components are required not to have defects such as looseness, deformation, excessive wear, excessive clearance, and weakened elasticity; In particular, the deformation of the suspension arm and the wear of the bushing and ball joint will make the wheel alignment inaccurate and prone to failure. The cost of maintenance varies greatly depending on the model, region, and level of repair shops, etc., and the specific situation shall prevail.
Second, the fault phenomenon.
1. The connecting pin (rod) of the shock absorber falls off or the rubber bushing (cushion) is worn and cracked.
2. The oil volume of the shock absorber is insufficient or there is air.
3. Poor sealing of shock absorber valves.
4. The piston and cylinder barrel of the shock absorber are worn excessively and loose.
3. Fault diagnosis and elimination.
1. Check whether the connecting pins (rods), rubber liners and connecting holes of the shock absorber are damaged, falling off or cracked, and if so, they should be repaired or replaced in time.
2. Check whether the shock absorber has oil leakage and obsolete oil leakage traces.
3. Press the bumper of the car hard, the hand is loose, if the body can have 2 or 3 jumps, it means that the shock absorber is good, otherwise, the fault is inside the shock absorber, and it should be removed for maintenance.
4. Wheel alignment: check the wheel alignment to make the positioning parameters within the specified range.
3. Miscellaneous. 1. Suspension springs.
Spring wear check: cracks, wear or damage.
Elasticity check. Spring installation: the installation position and direction are correct, and the clearance meets the regulations.
2. The vehicle is overloaded or overspeeding on uneven roads, or the speed is too fast when turning, and the load suddenly increases.
When the vehicle is used under the condition of long-term overload or uneven loading, the load of the suspension spring is not released according to the regulations when the vehicle is sealed.
If the maintenance is not timely, the lubrication between the suspension springs is poor or there is no lubrication at all, which reduces the relative displacement capacity between the suspension spring plates, resulting in a decrease in bearing capacity and breakage.
The U-bolt is loose, and the load is concentrated on the top few pieces of the leaf spring, which are prone to breakage.
The curvature of the new suspension spring blades replaced is different from the curvature of the original.
The car has too much emergency braking (especially in the case of good front braking and poor rear braking), or when going downhill with full load, the emergency braking is used to move the car load forward, and the front suspension spring is suddenly subjected to additional load, resulting in the suspension spring.
One or two pieces are broken.
3. Suspension rods.
Pry the fixing frames of each suspension arm, support bar, stabilizer bar and control bar, check the clearance in all directions, and re-tighten or transverse the bushing if it is too large.
For the strut suspension, you can use the hand to push and pull the top of the wheel to check whether the upper bracket is loose or damaged.
Check the suspension arms for deformation.
Check the installation connections.
Check the gap of the ball joint joint, if the gap is too large and the wear is serious, it should be replaced.
4. a shock absorber.
Check that the shock absorber should be free of oil leakage, deformation and damage, otherwise it should be replaced.
Check the installation of the shock absorber.
Check the working condition of the shock absorber: press the body with your hands.

Yes. The all-new 2014 Range Rover Sport (7-seater).
Appearance: The 2014 Range Rover Sport has a simpler, more sleek and tough appearance, which is unified with the new high-performance engine. New LED headlights, a two-spoke grille and a larger grille create a new angular front image that enhances the car's sporty character. >>>More
From the eighth-generation Camry to the C-HR, and then to today's new generation of Levin, these three cars have one thing in common in addition to the Toyota logo, that is, they are based on the TNGA architecture; Unlike Volkswagen's MQB, Nissan Renault's CMF, and BMW's CLAR, Toyota's TNGA architecture is not only "modular R&D + production", Toyota engineers have also added "time concept" to the modular "DNA" of TNGA architecture, < >>>More
You go to the second-hand car market to take a look Then there must be a Bora I used to drive a Bora The acceleration is really good Very flexible It's really a good car The appearance is also the classic style of Volkswagen The integrated rectangular headlights are very powerful Later, I changed the horse 6 and didn't have that feeling My car sold to the second-hand car market I bought it in 03 and sold it in 06 The car was in good condition at the time When it was sold, the odometer was 90,000 kilometers 90,002 was processed What you want should be Bora R version This car is better than the ordinary ** of the year is also more expensive I estimate that the 60,000 kilometers of Bora R will be about 13w Support you to buy Bora I will regret selling Bora!
A new generation of Jaguar in the new range.
After Ford took over Jaguar in 1989, it invested £200 million to redesign the XJ40 to make it even higher. After a redesign, the new XJ, codenamed X300, was introduced in 1994. It uses a modified liter and liter V-8-cylinder AJ-16 engine and a 6-liter V12 engine. >>>More
