In detail: Mitsubishi Lancer 9 steering rack DIY repair from a real master for the site my.housecope.com.
We are considering repairing rails on 2 cars with standard equipment and “Sport” at once.
... 2 liter, with plastic clamps on the anthers.
... the traction boot was "updated" by 1.6 - wrapping it with tape.
... another option for "restoring" the anther with electrical tape.
... electrician and suspension are incompatible concepts. the result.
... the consequences are sad - the rack and pinion shafts are "eaten" by corrosion.
The prices of the new rail are impressive. 2.0l. rake "Sport".
The removal process is the same, the fastening points are identical, but the mechanisms are different and differ in the diameter of the gear shaft. On a 2.0 motor, its diameter is increased; another type of adjusting nut.
.. the right sleeve is also different.
... accordingly, the stuffing box seals, or rather the high-pressure cuffs of the hydraulic cylinder are different.
Steering gears are equipped with Kayba hydraulic pumps, which differ from other manufacturers in increased working pressure (holding pressure reaches 97 bar. At 750 ± 100 rpm).
... out of "sporting interest", as well as cost considerations, an experiment was conducted to install oil seals from another rail, suitable in size - that's what came of it. packing spring extended by pressure.
Manufacturer. the former Koyo corporation. 1.6 liter engine ..
... remove the plastic cover and unscrew the bolt in the cabin.
..further all work is done from below. longitudinal beam with front support of the power unit.
... intake pipe of the muffler. it is better not to try without gas.
... rear engine mount bolt.
... the muffler lowered down must be supported by a stand, otherwise the wiring of the 2nd oxygen sensor can be cut off.
Video (click to play).
... even better, unplug the connector.
... subframe bolts and nuts - lower it down as far as possible.
... 4 rear engine mount bolts.
... feed tube bolt and return hose.
... four bolts securing the rail.
... and the mechanism is removed. Koyo rake.
... “Along the way” the stabilizer bushings are replaced.
... the shaft with the wear of the central teeth - a consequence of excessive entrainment by the adjustment of the clamping rim, “the shoby did not knock”. the defect manifests itself by the appearance of a free wheeling of the steering wheel within the limits of 8 - 20 º, in the straight-ahead position.
... after consultation with the owners of the car, it was decided to restore the rack and pinion shaft.
... checking the build quality. holding pressure - 100 bar.
The owner of a Lancer with a 1.6 l engine also complained about the knock of the steering mechanism - the rack was modified.
The warranty for the type of work performed is 6 months, provided that the customer observes the deadlines for replacing the power steering fluid.
Recently. on the pages of our site> we talked about replacing the steering rods and tips Lancer 9. In this article, it's time to talk about repair of the steering rack on Lancer 9.
So the rail flowed on the Lancer IX, dismantled, the reason is a rusty shaft. Ordered a new shaft MR589006, a new shaft support MN101696, rail seals 435.PS651 external 435.PS543 internal if you take the original repair kit, then only money down the drain, well, anthers clamps stabilizer and levers seals, since to disassemble a lot, it was decided to change everything. 8500r came out for spare parts of the rack. one day's work is not complete. We start from under the steering wheel, unscrew the gimbal, which is hidden behind the plastic protection, then using the pliers above the column, we will clamp the clamp and pull the shaft into the column:
We remove the protection, knock out the tips, unscrew the muffler only from the catalyst, and the sensor, if not unscrewed, we cut it off and then twist it, remove the mini stretcher with the front engine cushion, unscrew the rear cushion only from the engine, disconnect the hoses from the barrel and from the pump, if you don’t if you change the stabilizer and oil seals in the levers, then we do not touch them (if you will, then you need to unscrew the ball ones and the subframe will come out with levers).
We unscrew the rear bolts of the subframe, and pre-lubricate the front pins with brake fluid so as not to turn the mortgages.When unscrewing the last nut of the subframe, the partner needs to hold the subframe, the subframe is not heavy. It can be lowered and it will hang on the levers, unscrew the support, do not touch the stabilizer, unscrew the rail, and take it out by turning in different directions. That's it, the rake has been removed.
We begin to disassemble, unscrew the rods, tubes, on the right side of the movement, the ringed bushing, twist it until its end appears, pick it out with a screwdriver and twist it further (when assembling, insert it with the bent end into the bushing and twist it all over) unscrew the cover by 22 there we unscrew nut on 17.On the reverse side, unscrew the large nut, the size I do not know, twisted the gas, there will be a spring and a support, take out the worm with the body, take out the shaft, the oil seal remains in the body, we buy a gas can with a burner and heat the body to burn out the oil seal, you need it will pick it up with a long flat screwdriver, break it and take it out, wipe it all in the salary, if you want, to insert a new internal oil seal, use the shaft, put the oil seal on it, insert it all the way into the body and no longer pull out the shaft! We change the oil seal in the outer sleeve, and assemble everything in the reverse order, fasten the cardan with the very last one, fill in dextron 2 and pump the system. Bottom line: you installed a new steering rack for Lancer 9... If you do not start the anthers again, then a century will be enough for two.
Mitsubishi Lancer IX is a front-wheel drive passenger car that is very popular among drivers of all generations. High-quality service and timely repair of a Japanese car guarantee its long and reliable service on the road.
Often, with a mileage of more than 150 thousand km, Lancer 9 cars have problems with the steering mechanism. To solve these problems, it is necessary to understand the design features of the vehicle control. The node system consists of:
steering wheel with a column;
rail with power steering system;
power steering pump;
high and low pressure hoses;
the compensating reservoir of the hydraulic booster.
The steering gear is the most complex element of the car and is used to transfer the force of the steering column to the steering wheels. It has the following construction:
a rotary device that rotates the shaft transfers rotation to the gear;
the gear, rotating to the sides, gives an impulse to the movement of the toothed rack located inside the rack housing;
the toothed rack, when rotated horizontally, creates movement for the rods that move the wheel levers.
The main typical symptoms of a malfunction when it is necessary to repair the steering rack "Mitsubishi Lancer 9":
hydraulic fluid leak - occurs when shaft seals are worn or corroded;
knocking when steering - caused by wear on the center tooth of the shaft or ball joint. The characteristic knock can be caused by damage to the gimbal;
a tight turn of the steering wheel and not returning it to the central position is a consequence of the deformation of the shaft or crankcase.
itchy sound when turning the steering wheel - typical when the oil level in the tank drops;
Difficulty turning the steering wheel at low speed - indicates wear on the flow valve;
poor turn of the steering wheel accompanied by a characteristic whistle - occurs when defects appear on the rotor pair or mating surfaces, as well as the weakening of the drive belt.
The steering gear of Mitsubishi is generally very reliable and designed for high mileage. However, when a number of reasons arise, the working condition of the unit is significantly deteriorated. These include:
driving at high speed with uneven road surfaces and ignoring high obstacles and curbs;
untimely or poor-quality replacement of hydraulic fluid;
ignoring the systematic inspection of the anthers of the steering rack "Lancer 9", which can lead to the destruction of rubbing elements when debris and small particles enter.
If, while driving Mitsubishi Lancer 9, the above signs of a part malfunction appear, urgent repair or replacement of the steering rack is required.
Therefore, in order to correctly identify one or another breakdown and troubleshoot problems associated with car control, it is necessary to diagnose the unit.
Full computer diagnostics is carried out by qualified specialists in a professional car service using special equipment.
They do the necessary disassembly, troubleshooting and troubleshooting of steering systems and amplifiers.
Repair of the Mitsubishi Lancer 9 steering rack is usually carried out by a standard procedure: complete disassembly of the unit, identification of defects, cleaning of parts and replacement of worn out components.
Depending on the complexity of the breakdown, the repair can be superficial, complete or with the replacement of the mechanism.
Surface repairs are carried out to prevent a situation of complete failure of the steering mechanism and the vehicle as a whole.
Professional cleaning and adjustment of the unit is carried out:
tightening of tie rods and tips;
strengthening of bearings;
rail adjustment.
During the repair, a number of works are carried out:
complete disassembly of the mechanism;
troubleshooting;
elimination of corrosion and depletion of parts, cleaning with a grinding machine;
shaft straightening;
boring of the rack body;
restoring the original size of the part using thermal spraying;
elimination of spline gaps;
restoration of rods, tips, ball joints and so on.
If it is necessary to completely replace the faulty elements of the steering rack "Lancer 9" due to their deterioration, the following works are carried out:
replacement of oil seals, teflon or rubber rings, bearings, cuffs, etc.;
replacement of deformed and corroded rods;
replacement of tips and rods;
fluid replacement in power steering;
replacement of silent blocks;
replacement of the crosspiece and shaft support;
replacement of the high pressure tube;
replacement of the rail.
After the repair, the hydraulic fluid is filled and the mechanism is fully checked.
As a rule, it takes from several hours to two days to restore the operability of the steering unit, depending on the wear of the parts and the competence of the auto repairmen.
Steering reliability while driving is very important, therefore professionalism in the work of specialists plays an important role. At the end of the work, they usually do wheel alignment and give recommendations for further car maintenance.
The steering control or SRU Lancer 9 fails, on average, after 70-100 thousand kilometers on the road of moderate quality. You can suspect the problem immediately, as soon as the traction begins to knock. If the Mitsubishi Lancer 9 steering rack completely breaks down, it becomes necessary to carry out appropriate repairs.
Setting up or adjusting the steering shaft of a Lancer 9 car can be done by hand if the part is rearranged from another car or altered. As a rule, the factory rail is extremely difficult to configure, it is easier to replace it, especially since it is inexpensive.
As a rule, the adjustment of the converted right-hand drive Lancers is carried out with a spanner wrench from under the wheel on the driver's side. It will be extremely difficult to adjust the Lancer's factory rail, since there is a manufacturer's protection installed there.
If the lock nut is loose, then you need to tighten it half a turn. It is screwed onto a bolt. Typically, this bolt may require a sprocket wrench to help hold it during adjustment.
The bushing and anthers are the first failures of the SRU. If we are talking about adjusting the steering Lancer 9, then the first thing to do is tighten the bushing. This requires a special key. If it is absent, you can make the tool yourself from a 19 bolt 10 cm long. A force of about 23 Nm is exerted on the sleeve.

At the end of the work, it is imperative to bleed the power steering system, since the lower hose fitting will be removed.
The Lancer's steering wheel is the main control link, which at its disposal has a systematic hydraulic-type amplification mode, as well as a pump, a compensation barrel and a pressure hose.
To consider in more detail the principle of the structure and functioning of the SRU, best of all, directly visually viewing the corresponding video material.
