Replacing the steering gearbox is an important part of steering system maintenance, especially when it comes to older models of the domestic auto industry. Drivers of classic models often have to deal with problems such as play, stiff steering, or oil leaks. In this article, we will take a detailed look at how to replace the steering gearbox on a VAZ 2107, as well as on a similar model - the VAZ 2106.

What is a steering gearbox and why replace it

The steering gearbox of a car is a unit that transmits force from the steering wheel to the steering mechanisms of the front wheels. It allows the driver to control the direction of travel with minimal effort. Over time, the steering gearbox can wear out: play, jamming, noises appear, and feedback deteriorates. In such cases, it is necessary to either adjust or completely replace the gearbox.

When to replace the steering gearbox

Before replacing the steering gearbox on a VAZ 2107 or VAZ 2106, make sure replacement is necessary. The main signs of malfunction are:
  • strong play in the steering wheel;
  • uneven, "jerky" steering wheel rotation;
  • knocking sounds in the area of the steering mechanism;
  • oil under the gearbox (seal leakage);
  • difficulties when driving at high speed.
If adjustment does not help, replacement is required.


How to replace the steering gearbox on a VAZ 2107

Replacing the steering gearbox on a VAZ 2107 takes from 2 to 4 hours, depending on experience and the condition of the fasteners. The work can be done independently using a standard set of tools.

Tools and materials:

  • jack and stands;
  • set of wrenches (13, 17, 19);
  • pry bar;
  • WD-40 or similar;
  • new steering tie rod (if necessary);
  • new steering gearbox;
  • hammer and chisel.

Step-by-step instructions:

1. Vehicle preparation

Place the vehicle on a level surface, engage the parking brake, and place chocks under the rear wheels. Open the hood. Disconnect the battery terminal for safety.

2. Removing the steering column

Unscrew the steering shaft in the cabin (between the steering wheel and the engine bulkhead). Then unscrew the universal joint connecting the shaft to the gearbox. For convenience, you can remove the steering wheel.

3. Removing the steering tie rod

From under the car, disconnect the steering tie rod from the gearbox. If necessary, use a ball joint puller.

4. Unscrewing the steering gearbox

In the engine compartment, find the gearbox (it is attached with three bolts to the body). Pre-treat the bolts with penetrating fluid (WD-40). Then carefully unscrew and remove the gearbox.

5. Installing the new gearbox

Clean the installation area. Install the new VAZ 2107 steering gearbox and tighten the mounting bolts. Check the clearance and position of the mechanism.

6. Assembly

Reconnect the steering tie rod, connect the universal joint to the steering shaft, and tighten all bolts. In the cabin, make sure the steering wheel is positioned straight.

7. Check

Lower the vehicle and reconnect the battery. Check for play and smoothness of steering wheel rotation. If necessary, perform adjustment.

How to replace the steering gearbox on a VAZ 2106

The procedure for replacing the steering gearbox on a VAZ 2106 is almost identical to that described above. The main difference is in the fastening details and the design of the steering column, but the general principle remains the same. Also, when replacing on a VAZ 2106, pay attention to the condition of the steering tie rods and the pendulum lever - wear of these elements often goes "in tandem" with the gearbox.

Tips for replacement:

  • Before installation, check that the splines of the new gearbox match the shaft.
  • If the bolts are heavily corroded, it is better to use a pipe wrench or heat.
  • After replacement, it is advisable to perform a wheel alignment.
Now you know how to replace the steering gearbox in a car, including how to replace the steering gearbox on a VAZ 2107 and VAZ 2106. This operation is quite feasible for a car owner with a minimal set of tools. The main thing is to follow the sequence, use quality parts, and not forget about safety.
