Jeep Grand Cherokee 4 / WK2

The fourth-generation Jeep Grand Cherokee, known since 2009 as the WK2, is built on the same platform as the Mercedes M-Class W164. The project was created when the American brand was still under German control. But only American gasoline engines and an Italian diesel engine fell under the hood, since the Jeep came under the leadership of Fiat in 2009. It should be admitted that all this has only benefited. The Jeep has received many new technologies, including air suspension. The next model was noticeably larger than its predecessor, which affected the mass. In addition, an independent suspension appeared on the rear axle. Has the comfort side of the road affected off-road opportunities? Absolutely not! The Jeep has remained true to tradition and the flagship model is not afraid to move out of the way. And the depth of the ford overcome reaches 508 mm.

Engines

The gasoline engines are of American origin. These are interesting aggregates. The base volume of 3.6 liters belongs to the new Pentastar series. Combined with an 8-speed automatic transmission, it is quite lively and consumes 11-15 liters of fuel per 100 km. 3. 6 of the first years of production may require repair due to a design flaw in the rocker. One of them could jam, which led to wear of the hydraulic compensator and camshaft. For the restoration of the required more than 100 000 rubles. If you find an outside knock, you should replace the rocker and hydrocompensators. Fortunately, the problem was not a general one, and after the first quarter of 2013, modernized rockers began to be installed, and the defect ceased to occur. It is also worth mentioning the point associated with the removal of the catalyst. After this procedure, the engine often starts to consume a lot of oil. To avoid this, instead of a native catalyst, at least a universal catalyst must be installed. In the cars of the 2015 model year, a new basic engine appeared - a 3-liter atmospheric V6. The remaining gasoline engines are V8 - 5.7 liters, 6.4 liters and 6.2 liters. From a technical point of view, the 5.7 is a rather strange unit - one camshaft in the block and 16 valves. At the same time, it is quite strong and moderately economical. 5.7 V8 is equipped with a system of shutting off half of the cylinders. The system is very sensitive to the quality of the oil. After prolonged use of low-grade motor oils, deposits are formed that block the operation of the system.

Transmissions

Transmissions have a significant impact on dynamics and fuel consumption. All of them are automatic, but in different years the supplier has changed. The previously familiar 5-speed NAG1 from Mercedes in 2014 gave way to the 8-speed ZF. It allowed to reduce fuel consumption by about 1 liter.

In the case of an older 5-speed automatic transmission, in addition to changing the oil, it is necessary to eliminate its leaks. They appear as a result of the wear of seals. With timely detection, it will be possible to do with repairs, which will cope with almost any service. Otherwise, the box will fail (90-120 thousand rubles for a full bulkhead).

Other common malfunctions of the 5-speed automatic are the failure of the electric board (10,000 rubles) or the solenoid of the blockage of the hydraulic transformer (9,000 rubles).

In the more modern ZF, tremors occur, the responsibility for which, as a rule, lies with electronics.

To control the gearbox, a classic selector was first used, and since 2013, a non-fixable lever was used, independently returning to its original position after switching on the transmission. The decision was not very successful. It is easy to get the “P” set wrong. As a result, the car could drive when the engine was running and the driver was leaving the car. In the future, the manufacturer within the framework of a free service promotion updated the management program. And since 2017, the classic type of gear selector with fixed positions has been used again.

All-wheel drive system

Off-road capabilities largely depend on the transmission. Basic versions imported from abroad privately can be rear-wheel drive. Such cars are not worth buying. There are several all-wheel drive versions of the transmission. The Quadra-Trac II and Quadra-Drive II are usually used. Both use a central differential and a gearbox. In the first variant, you have to be content with only locking the wheels with the help of brakes, and in the Q-D II there is an electronically controlled locking of the rear differential (ELSD). In its predecessor, the ELSD was also in the front axle, and here only in the rear axle. There are also Quadra-Trac (modifications of SRT and Trackhawk). It is the same transmission as the QT II, but without a gearbox. The Selec-Terrain system helps off-road. The driver uses a handle to indicate the type of surface on which he is moving. Since the sports versions did not have a gearbox, the 4WD LOW button was missing. The air suspension provided 5 options for ground clearance (from 165 to 271 mm). It wasn't in the basic versions. Sometimes the transmission needs repair. For example, when noise from the rear gearbox appears, bearings wear out (50-70 thousand rubles). Characteristic of gasoline versions of the first years of release. Over time, oil leaks may be detected in the area of the rear bridge. Replacement of oils (about 7000 rubles with work) is subject to. The neglect ends with expensive repairs. After 150-200 thousand km, the ELSD rear differential lock motor may fail. The new motor is very expensive - 80-100 thousand rubles.

Walking

The elements of the chassis are relatively strong. After 100-150 thousand km, the front arm valve blocks may require attention. A little later, ball supports are handed over (from 2000 rubles for an analogue).

Silent blocks of levers on the rear axle usually serve more than 150-200 thousand km.

But the Silent blocks of the rear subframe can wear after 100-150 thousand km. Soon it is the turn of the Silentblocks of the rear gearbox (5000 rubles plus 6000 rubles work).

In old cars will have to reckon with the wear of air suspension. Rear cylinders can lose weight after 100-150 thousand km (from 8000 rubles for an analog or 51 000 rubles for the original).

The front pneumocyllons are much more durable. Sometimes it is necessary to eliminate air leakage through fittings (fittings).

Front hub bearings can make noise in 100-150 thousand km. They change in the collection with a hub (18 000 rubles for the original or from 5000 rubles for an analogue). The rear bearings are changed separately, but they last much longer.

The steering rack can knock or leak, having passed more than 150-200 thousand km. The cost of eliminating the defect will be about 18-27 thousand rubles.

Other problems and malfunctions

Grand Cherokee doesn't usually have any problems with corrosion. Plaque on the chassis elements, where the manufacturer did not protect the parts from corrosion, is natural.

Rust on the body parts appears after poor-quality repair of damages received as a result of an accident. There are exceptions, however. A number of owners faced defects in the factory paint coating of the hood, doors (in the area of door handles) and the upper point of attachment of the front wing.

In the restyled versions, fogging of headlights is detected over time.

The interior has a nice design and good materials. If something creaks, then most likely the plastic was removed and poorly collected.

Particular attention should be paid to the generator. His weak spot is the diode bridge. The cost of repairs is about 8000 rubles. A number of machines have been hit by a recall campaign to replace the generator.

Plastic gears actuator flap stove become unusable after 150-200 thousand km. The cost of the gear 900 rubles, and work on the replacement - about 5000 rubles.

With age, the radiator of the air conditioner is often rented (from 6000 rubles for an analogue or 26 000 rubles for the original).

Before buying, you should spend money on a thorough diagnosis of the SUV in an authorized service. In addition to the story, you can check whether this instance needs a service promotion, of which there were quite a lot.

Trailhawk

This is the version that is best prepared for off-road. There is additional protection of the bottom, improved transmission, air suspension and AT tires. The SUV is different and a number of stylistic accents. It has added to the 2017 model year.

SRT

The SRT was named the fastest Jeep ever. It received an adaptive suspension, reduced by 30 mm clearance, 20-inch wheels and high-performance brakes. The speed was taken care of by an atmospheric 6.4 liters, offering 90% of the torque in the range from 2800 to 6000 rpm. Little? In 2017, the Jeep offered 6.2 liters with a compressor, developing 700 (710) hp.
