Volkswagen Transporter T4 Power Steering Rack 1990-

VW Transporter T4 — The Versatile Workhorse

This hydraulic power steering rack (OE 701422055C and cross-references 702422055N, 702422061Q, 702422061J) fits the Volkswagen Transporter T4, produced from 1990 to 2003. The T4 was a revolutionary vehicle for Volkswagen — it was the first Transporter to use a front-mounted water-cooled engine and front-wheel drive, replacing the rear-engine, rear-drive layout that had defined every previous VW van since the original Type 2. This unit is configured for right-hand drive (RHD) vehicles, making it suitable for UK, Irish, Japanese, Australian, and other RHD market T4 models. The T4 was marketed as the EuroVan in North America and the Caravelle in certain European and Asian markets.

Four OE Numbers — What They Mean

This steering rack cross-references with four different OE numbers: 701422055C, 702422055N, 702422061Q, and 702422061J. The reason for so many numbers is that the T4 was produced over a 13-year span with multiple engineering revisions, and Volkswagen assigned different part numbers to each revision. The "701" prefix identifies early T4 models while "702" identifies later variants with updated components. Despite the different numbers, all four refer to physically interchangeable steering racks with the same mounting points, hydraulic connections, and steering ratio. Our rack is manufactured to the latest revision specifications, making it a direct replacement for any of these four OE numbers.

RHD Steering Rack — Specific Challenges

Right-hand drive steering racks present unique manufacturing challenges compared to their LHD counterparts. The rack body, valve housing, and pinion assembly are mirror-image components — they cannot be produced by simply reversing an LHD rack. The internal valve body geometry must be precisely machined to provide the correct hydraulic assist direction for RHD steering input. KITLAMT manufactures dedicated RHD tooling for the T4 rack rather than attempting to adapt LHD production tooling, ensuring that each RHD rack delivers identical steering feel and assist characteristics to the original Volkswagen unit. This attention to RHD-specific engineering is why our T4 racks are trusted by UK and Japanese market importers.

T4 Van Fleet Maintenance Perspective

The VW Transporter T4 remains in widespread commercial use across Europe, particularly in the United Kingdom where it is the backbone of countless delivery, mobile workshop, and tradesperson fleets. For fleet managers, the steering rack is a scheduled maintenance item rather than an unexpected failure — most commercial T4 vans will need a rack replacement between 150,000 and 200,000 km depending on the severity of urban driving conditions. Bulk ordering steering racks for fleet maintenance reduces per-unit cost and ensures that vehicles spend minimal time off the road. KITLAMT offers volume pricing for fleet maintenance operations and can arrange scheduled deliveries to match your fleet's replacement cycle.

T4 Caravelle and Multivan — Premium Variant Considerations

The VW Caravelle and Multivan are the passenger-oriented premium variants of the T4 Transporter, featuring better insulation, more comfortable seats, and additional sound deadening. These vehicles often cover long motorway distances and their steering racks tend to develop a different failure pattern compared to commercial T4 vans. Rather than the heavy, leaky failures seen on delivery vans, Caravelle and Multivan racks typically develop a subtle vibration through the steering wheel at 80-100 km/h, caused by microscopic wear on the rack bar creating an uneven surface that the piston seal rides over. This vibration is often mistaken for wheel balance or tire issues, but persists after rebalancing and tire replacement. A new steering rack eliminates this vibration entirely.

Compatibility with T4 Engine Variants

The VW T4 was offered with an extensive range of engines over its production life: 1.9L petrol (AAC, AAF), 2.0L petrol (AAC), 2.4L petrol (AAD), 2.5L petrol (AAF, ACU, AEN), 2.5L TDI diesel (AJT, AYC, AXL, AYC), 2.4D diesel (AAB), and 2.5D diesel (AJA, AAB). All of these engine variants use the same steering rack regardless of displacement or fuel type. The power steering pump varies between engines (different mounting brackets and pulley configurations), but the rack itself is universal across the T4 range. This makes the 701422055C / 702422055N rack one of the most versatile replacement parts available for the T4 platform.
