A squeak that occurs when turning the steering wheel in a Mitsubishi Lancer 9, most often indicates critical drying of the lubricant in the upper bearing or wear of the universal joint of the shaft. This unpleasant sound appears immediately after starting the engine or when turning the steering wheel in place and is a direct signal of friction of metal parts without a proper lubricant film. Ignoring the problem leads to accelerated destruction of the shaft and the appearance of backlash, which will subsequently require an expensive replacement of the entire assembly.

Owners of cars of this model are well familiar with the design features of the control system, where rubber-metal elements lose elasticity over time. Dry bearing begins to emit a shrill whistle or squeak, which is transmitted to the steering wheel and irritates the driver. Diagnosing a malfunction requires carefully listening to the operation of the unit and sequentially checking all moving connections to accurately determine the source of the noise.

The main reasons for the appearance of extraneous soundsCreaking noise in the steering column Lancer 9 does not always mean a breakdown of the unit itself; often the problem lies in adjacent components or operating conditions. The main enemy of the mechanism is moisture and dust, which penetrate through damaged boots and wash out the lubricant from working areas. As a result, metal begins to come into contact with metal, causing a characteristic friction sound that intensifies as the temperature in the engine compartment changes.

The second common cause is wear and tear. universal joint steering shaft, which connects the column to the steering rack. This unit contains needle bearings that are deprived of the possibility of lubrication during operation, and when exposed to water they quickly rust. Also, a source of noise can be the plastic bushings that attach the column to the body, which dry out over time and begin to rub against the metal due to vibrations.

⚠️ Warning: Driving for a long time with a squeaky steering wheel can cause the universal joint to jam, which will create a dangerous situation on the road when trying to maneuver.

Noise source diagnosis and localizationTo accurately determine the location of the squeak, it is necessary to carry out a series of simple manipulations that do not require complex equipment. The first step is to remove the plastic steering column trim and have an assistant turn the steering wheel left and right while you listen carefully and feel the components. The sound can come from both the upper bearing under the steering wheel and the lower driveshaft, located deep in the engine compartment above the steering wheel.

If, when you turn the shaft by hand, you hear a creaking sound in the area of the retaining ring, then the problem is in the upper plain bearing. In the case where the sound comes from below and is accompanied by slight jamming, you should look for the cause in steering shaft crosspiece. Sometimes the creaking is imitated by plastic elements of the dashboard or steering column switches, so it is important to eliminate their friction on the column by gently rocking the lining.

How to distinguish the creaking of a column from the creaking of a rack?

The creaking of the steering column is usually heard in the cabin and depends on the rotation of the steering wheel, regardless of whether the engine is running or not (although with power steering the load changes). Steering rack creaking often occurs when driving, on uneven surfaces, and is localized in the front part of the car under the hood.

Required tools and suppliesTo properly troubleshoot a problem, you will need a minimum set of tools that can be found in any car enthusiast’s garage. The main attention should be paid to choosing the right lubricants, since the use of inappropriate compounds can only temporarily suppress the problem or damage the rubber elements.

It is important to choose the right bearing grease, which will retain its properties over a wide range of temperatures and will not leak over time. For plastic bushings and rubber seals, it is better to use silicone lubricants that are not aggressive to polymers. It is not recommended to use graphite lubricants in places of contact with plastic, as they can cause accelerated destruction.

It is critical to clean all surfaces of old dirt and rust before applying a new lubricant, otherwise the effect will be short-lived.

Step-by-step instructions for bearing lubricationThe process of restoring the silent operation of the steering column begins with dismantling the decorative covers and accessing the upper rotation unit. After removing the steering column switches, access to the retaining ring and the shaft itself opens, where the source of the unpleasant sound most often lies. Carefully clean visible parts of the shaft from dust and old grease using a rag and cleaner.
💡

Before applying new lubricant, blow out the assembly with compressed air or use WD-40 to wash away sand and small metal shavings.

Apply a generous coat of grease to the shaft and bearing area, then rotate the steering wheel several times to distribute the grease. If the creaking is associated with the upper unit, this procedure completely eliminates the problem in 90% of cases. In cases where access is difficult, you can use a syringe with a thin needle to deliver lubricant to hard-to-reach places without complete disassembly.

  • 🔧 Remove the lower steering column cover by unscrewing the fastening screws.
  • 🔧 Clean the shaft from dirt and check for play in the vertical plane.
  • 🔧 Apply lithium grease on the bearing and shaft, turning the steering wheel.
  • 🔧 Reassemble the structure in reverse order and check the result.

Repair and maintenance of universal jointIf diagnostics show that the source of the noise is in the lower part of the shaft, more serious intervention will be required. Cardan joint on Lancer 9 made in the form of a needle bearing covered with a rubber boot, and often this is where moisture gets in. For high-quality repairs, it is better to remove the unit from the car, which will require unscrewing the bolt securing it to the rack and dismantling the shaft itself.
Secrets to extending the life of a cardan

After disassembling the driveshaft and cleaning the needle bearing from rust, you can fill it with high-temperature CV joint grease. This will significantly extend the life of the unit even when used in harsh conditions.

In some cases, simple lubrication does not help due to wear and tear on the bearing needles. Then careful troubleshooting is required: if there are deep cavities on the metal surface, the assembly must be replaced. However, if wear is minimal, careful cleaning and padding grease allow you to restore silent operation for a long time.

⚠️ Attention: When installing the shaft back, pay attention to the position marks so as not to disturb the wheel angle and ESP settings.

Table of faults and solutions| Malfunction | Characteristic sign | Elimination method | Required materials |

|:--- |:--- |:--- |:--- |

| Upper bearing drying out | Creak when turning the steering wheel in place | Bearing Lubrication | Litol-24, rags |

| Cardan Joint Corrosion | Crunching and jamming of the shaft from below | Disassembly, cleaning, lubrication or replacement | Grease for CV joints, keys |

| Wear of plastic bushing | Knock and squeak when shaking | Replacing the bushing or winding | New bushing, electrical tape |

| Moisture getting into the column | Creaking after washing or rain | Purging and conservation lubrication | WD-40, silicone |

Prevention and recommendations for useTo prevent the squeaking problem from returning in the near future, it is important to follow certain operating and maintenance rules. Regular car washing should not involve direct exposure of a high-pressure jet to the area of ​​the steering column and universal joint. Periodic checking of the condition of the boots and seals allows you to identify the initial stages of destruction before sound signals appear.

It is also worth paying attention to the condition rubber seals in the floor of the car through which the shaft passes. If they dry out or shift, moisture and dirt will freely enter the mechanism. timely replacement of these cheap parts will save expensive components from corrosion and premature failure.
