How to choose a repair kit for the steering rack

A repair kit is used to extend the lifespan of components. Let's consider:

• Classification and Composition of Repair Kits;
• When a Repair Kit is Needed;
• How to Choose the Right Kit.

Composition of the Repair Kit

The appearance and composition of the kit are influenced by the type and model of the steering gear. To understand which kit to choose, you need to familiarize yourself with the classification of kits, which is similar to the classification of steering gears:

• For mechanical steering gears;
• For power steering gears.

In the repair kit for "dry" (mechanical) steering gears, fewer components are included because the design is simpler:

• Dust seal on the vertical shaft;
• Guide bushing;
• Sealing rubber rings.

The second type of repair kit is for power steering gears. Typically, the following elements are included:

• Seals on the gear rack;
• Seals on the distributor - top-bottom;
• Complete set of Teflon and rubber rings for the distributor and gear rack piston.

Depending on the specific steering gear construction, the repair kit may also include a guide bushing, O-rings for it, slides on the thrust stone, O-rings for the hoses, anti-dust seals, and more.

Model-specific parts affect the quantity and dimensions of the components. For example, in the Mercedes-Benz Sprinter 2-t, 3-t, and 4-t (2000-2006) steering gear, two types of distributors were used - with a wide or narrow roller. The repair kit for this model will include components for each distributor. Moreover, for most steering gears, only one less extensive kit is suitable, containing 5 Teflon rings - 4 for the distributor and 1 for the gear rack piston.

When to Use a Repair Kit

A repair kit is needed when:

• Oil leaks from the vertical shaft or accumulates in the rod cover;
• There is play in the gear rack or vertical shaft. Note: the repair kit may not always help because the teeth may be worn.

It is known that the main reason for buying a repair kit is a gearbox failure. Remember that the steering gear is a crucial unit that affects the entire steering system. In the event of gearbox damage, it is best to consult a workshop. A professional will assess the unit's condition and, if necessary, suggest using a repair kit.

Technical inspection is a regular procedure during which a professional checks the condition of each unit. If a potential part failure is identified during the inspection, it should be removed immediately and checked on a special stand or disassembled into individual parts. Not all damage can be confirmed without disassembling the part.

Methods of Selecting a Repair Kit

There are only two methods:

• Use the OE number or VIN to find the appropriate kit independently;
• Contact a parts supplier - such companies have the right program for verification.

Having all the vehicle data, you can try to choose a kit yourself, but it's essential to note that several types of steering gears could be installed in one model. However, it is best to consult professionals as they will surely choose the right kit, saving time primarily.
