How to fix a steering rack on a Mitsubishi Lancer 9?
Repair of the Lancer 9 steering rack is different, but as a rule, the main process, which is also the most difficult, is grinding and polishing the shaft, because not only leaking oil seals will contribute to rack leaks and backlash or runout, but also the rack shaft covered with corrosion.
You also need to be able to disassemble and assemble the rack (so as to correctly, without confusing, put all the cuffs, gaskets and rings), but having damaged the shaft, the steering rack of the Mitsubishi Lancer 9 after such an unsuccessful repair with your own hands can be thrown into a landfill. In addition to tools for disassembly and repair, you will need graphite grease and a liter of brake fluid.
First of all, in order to carry out an independent repair of the Lancer 9 steering rack, you need to dismantle it from the car and start disassembling it. Disassembling the steering rack only to replace the repair kit for oil seals and bushings often does not give a positive result, because these rails require the restoration of the shaft without fail.
And here is the first problem for those car owners who decided to repair the ninth Lancer's rail in a garage, because there is hardly a lathe available, which you also need to be able to use correctly.
The shaft is sanded with sandpaper starting with coarse P80, then P180, P280, P320 and up to P1000 and ending with the finest grit. You should not get carried away with the process, because each stage needs to be controlled and measure the run-up along the shaft and you cannot tolerate more than 10 acres.
With such a repair of the steering rack, the most important thing is to ideally grind the working area of the shaft. Polishing is done with goi paste (applied to the shaft) and felt.

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 is 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 17.On the reverse side, we unscrew the large nut, I don’t know, we twisted it with a gas one, there will be a spring and a support, we 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, it will need to be tucked in a long flat with a screwdriver, break it and take it out, wipe it all in a salary box at will, in order 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.
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.

Let's take a closer look at the situations that the owners of the Lancer 9 face, regarding the steering rack or PP.
The first difficulty
Mitsubishi Lancer steering rack repair
In the SRU zone, a characteristic knock is heard, sometimes with recoil, and sometimes without it. The reason for this is often a worn hinge located on the steering rod and the tip of the same name. You can verify a malfunction in the PP using a simple test:
first, the steering wheel is turned quickly to the right, and then to the left;
if a knocking sound is observed during this manipulation, then the PP requires urgent repair or even a major replacement.
From a practical point of view, it is almost impossible to eliminate the above malfunction by sorting through the PP components, since for this you need to have an appropriate highly specialized store of knowledge and skills. They are, of course, rarely owned by the average motorist.
The exact cause of the sound can only be determined after the vehicle has been lifted onto a lift. This is necessary in order to detect various kinds of microdefects and traces of wear on significant components of the steering rack.
Second difficulty
Sometimes, when you turn the steering wheel after a solid run, there is a buzzing sound. This is a reliable indication of a hydraulic malfunction.

The most common occurrence of this phenomenon occurs when a little of the appropriate fluid (oil) has been poured into the hydraulic system or the high pressure hose has been replaced. The possibility of damage to the latter as a result of wear cannot be ruled out.
If a buzzing noise appears after replacing the hose, then there is no reason for excitement, since during operation it will stretch, and the extraneous sound will go away on its own.
It is justified to judge about a malfunction of the hydraulic system of the steering wheel if the steering wheel turns with a significant application of forces, which has never been observed before.
You can find out how to change the power steering oil with your own hands here.
Third difficulty
The steering wheel has practically ceased to function, and it takes incredible efforts to turn it. The cause of this functional phenomenon is often a PP defect. Water gets inside, which spoils not only the sleeve, but also the PP itself. In this case, a complete replacement is already being carried out.
It is extremely difficult to repair the node on your own, as mentioned above. If the part is in a faulty condition, then it is better not to hesitate with the replacement. Its approximate price is 3-4 thousand rubles, so this does not threaten with a big waste of funds.
Advice. At first, it is better to perform all stages of work not by yourself, but in tandem with an assistant, which will significantly speed up the repair process.
The Mitsubishi Lancer 9 steering rack is dismantled by removing it from the subframe. You should not rush when performing this technical manipulation, so as not to damage the nearby power nodes.
How to remove the steering rack from Mitsubishi Lancer 9
Sometimes it is extremely difficult to remove the PP in some trim levels of the 9th generation Mitsubishi Lancer, since it is held by the side members with the help of four mounting bolts.
Disassembly instructions look something like this:
the levers fixing supports are attached to the drains, which must also be carefully removed;
the rods are equipped with tips, they need to be pressed out and then unscrewed;
a special fastening beam with a longitudinal section can also interfere (it must also be carefully removed);
then it becomes possible to get to the hoses without any difficulty.
The hoses and subframe together with the rail must be removed without fail.
Attention. The subframe and PP are removed in a prefabricated form, after which they must be thoroughly washed from a dense layer of dust particles and other compounds that have accumulated during the operation of the car.
The hardest part is over, now it remains to install a new rail instead of the old one.
Thus, replacing the PP is easy. You can, of course, try to disassemble the old part and fix the malfunction with your own hands, but this will require a thorough bulkhead, diagnostics of all elements.
If the hydraulic fluid flows out from time to time, then the PP will certainly fail in any case. Since dirt, water and other corrosive substances regularly affect the CPU, the boot will rupture soon. Actually from this moment in time all problems begin.

It turns out that even the most durable part quickly fails due to a torn boot located on the steering tip. In fact, corrosion has a detrimental effect, which occurs due to the regular ingress of water. In this regard, anthers should be given special attention.
