How to adjust the suspension adjustment of the Land Cruiser five seven

1. 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.

Prado, Land Cruiser and Land Cruiser are all models of the Toyota Land Cruiser series According to the historical era, the Prado is LC80 The Land Cruiser is LC100 And the Land Cruiser is the most **, and it is also LC200 Prado currently has 2 displacements, one is 2700 and the other is 4000; The former is imported, and the latter is produced in Sichuan; The former configuration is very low, and the latter configuration is very powerful, including chassis lifting and other functions The Land Cruiser LC100 has been discontinued, which used to be divided into two displacements of 4500 and 4700, and is now replaced by the Land Cruiser LC200, in order to meet the needs of the ** purchase car can not be greater than 4000 displacement, the displacement of LC200 has been changed to 4000 and 4700. Land Cruiser LC200 is currently Toyota's most powerful SUV (produced in Changchun Fengyue factory), also known as the king of global four-wheel drive, with the world's first low-speed cruise assist system and KDSS oil suspension, but also provides intelligent active ABS, VSC, in addition to 10 airbags, 28 air conditioning outlets, car refrigerators, etc., so that its comfort is also higher than that of competitors!

LC100 and LC200 are liquid, that is, hydraulic, which is true, but Toyota off-road vehicles are overbearing and have air suspension!

It's air suspension. The old domineering is also yes.

There is variable suspension and air suspension, which the RAND does not have, only the high configuration has variable suspension, but the Prado has air suspension on the highest configuration.

The LC100 and LC200 are liquid, that is, hydraulic, and the Toyota off-road vehicle does not yet have air suspension.

There must be Ah, my Prado VX has it.

When using the Land Cruiser speed button, you can directly engage the gear without braking while driving, but do not do so at high speeds and engine speeds.

In addition, when the owner locks in the fifth gear with the speed button, the engine speed will not jump into the sixth gear even if it enters the red zone, and decreases in turn, and then the response speed of the throttle will be accelerated, and the shift time will be delayed, that is, the vehicle will accelerate faster than the D gear, but the fuel consumption is higher, and of course it is less environmentally friendly.

Speed English means speed, you are talking about the gear in the S gear, S gear is a sports gear in the general vehicle, Toyota too, the only difference is that Toyota's S gear will not only speed up the speed, but also limit the gear, you can use +-, that is, move the gear lever up and down to choose which gear to limit in, usually it will be lower than the highest gear by one gear, as the name suggests, for example, the land is six gears, you lock in the fifth gear with the S gear, the engine speed will not jump into the sixth gear when it enters the red zone, and it will decrease in turn Then the throttle will react faster, and the shift time will be delayed, that is, the car will accelerate faster than in D gear, but the fuel consumption will be higher, and of course it will be less environmentally friendly. Usually the manual will say to switch between D gear and S gear in a stationary state, in fact, it is no problem at low speeds, as long as it is not at 100km+, the car suddenly retreats to fifth gear in sixth gear so that there is a "trailer" phenomenon, and everything else is fine.

It can be adjusted by adjusting the screws. [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Your car has KDSS suspension, and the oil pressure must be adjusted as soon as the balance bar is moved, so that the body will be consistent [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Because the left side of the balance bar is hydraulic, it leads to left and right imbalance, and sometimes the left and right sides of the jack for tire repair will also appear on the left and right sides are not the same height, just run and run [If the car has a problem, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Front-wheel double wishbones (suspension for general pickup trucks, rear-wheel drive sedans such as Ruizhi, Audi A4, and performance cars).

The rear wheel integral axle type (the elastic element for vans is steel plates, while for cruisers is coil springs).

The advantages of coil springs are good comfort, the chassis can be raised by changing different springs, good off-road performance, and a wide range of tuning. Disadvantages: the bearing capacity is not as good as that of the steel plate, and the high-speed stability is not as good as the steel plate.
