Diagnosis and Repair of Steering Gearboxes
A steering gearbox is one type of vehicle control mechanism. Today, these units are mainly installed on trucks and heavy off-road vehicles, although they were previously used in passenger cars as well. The operating principle of the gearbox differs from steering racks. In it, the steering effort applied by the driver is transmitted using two perpendicular shafts - the primary shaft and the distributor shaft. A worm wheel is mounted on one, and a worm or "endless screw" on the other. Although the repair of worm gears is a service in demand, not all auto repair shops can provide it.
Signs that worm gear repair is necessary
Steering gearboxes are very reliable units. But despite this, it's necessary to regularly check their functionality and ensure they are in good working order. Symptoms of problems may include:
- heavy steering;
- play, noise, and vibrations when turning;
- lubricant leakage from the steering gearbox;
- steering wheel binding and uneven movement;
- the car veering to one side.
If one or more of these signs appear, it's urgent to diagnose the worm gear and repair it if necessary.
What does steering gearbox restoration involve?
The repair and restoration of a worm gear proceeds in several stages:
- Dismantling and washing the unit.
- Connecting to a special stand and checking parameters.
- Checking for play, leaks, and extraneous sounds.
- Complete disassembly and defect detection of the worm pair.
- Replacement of faulty parts.
- Polishing of shaft surfaces, seal seats, etc.
- Reassembly of the gearbox.
- Re-checking on the stand.
- Installation of the vehicle.

Problem: In the case of a critical discharge of a low-voltage battery (12–48 V), the electronics prevent charging because it is dangerous with Li-Ion batteries. The manufacturer recommends discarding fully functional batteries and replacing them with new ones. This is expensive.
Problem: We received an electric car with very discharged traction batteries. The problem is typical for the Fiat 500. During idle time, the batteries discharged below the permissible level, and the car's electric motor stopped starting.

Problem: Failure of Toyota hybrid batteries is a common problem that our customers come to us with. The battery cells degrade, making it impossible for the car to operate normally.
Problem: Land Rover Range Rover Sport 3.0 SDV6 Hybrid AT AWD - the hybrid system did not work, the VBB was in emergency mode. The car was running only on diesel fuel, the low-voltage battery was not charging.
Problem: None of the car's systems were working at all, it wasn't even possible to raise it on a lift because the air suspension didn't activate either. I had to install the Porsche near the repair box on "goat" stands.
Problem: Errors P0AA6, P1F0E - high voltage charging system service
Problem: The problem with the car was the incompatibility of the Chinese GB/T standard charging system with European charging stations. This created difficulties for the owner of the Audi Q4 e-tron, since the car, produced for the Chinese market, could not charge at European stations with the required speed and reliability.

Problem: The Hyundai Kona made a rather loud noise. The customer diagnosed the malfunction on his own - in his opinion, the gearbox was the cause of the extraneous sounds.
Problem: There was water and rust inside the rail, which damaged both the needle bearing in the cover and the torque sensor, i.e. both the mechanical and electrical parts
Problem: The client complained about a knock at the bottom – it was as if a gnome was sitting there with a hammer and hitting plastic with it. However, the dwarf did not always do this, mainly after an energetic ride. Then, the sound could disappear and reappear with a new sharp push on the pedal.
Problem: Destruction (wear) of differential satellites and, as a consequence, noises (hum) when driving the vehicle.
Problem: Steering rack leakage from under the tie rod dust cover

Problem: The owner of a Citroen C4 Picasso car came to us with a complaint about poor engine performance. The car literally could hardly drive: the engine would not rev above 2000 rpm and did not develop the necessary power. Fuel consumption increased significantly. The problem lies in the car's clogged particulate filter.
Problem: We were approached by the owner of a 2017 Citroen Berlingo with complaints of a knocking steering rack.
