Steering Rack Part Numbers and Families
The references below are identification guides collected from established specialist catalogues. They are not a direct interchangeability list. Confirm every digit on the original Volvo label, any Bosch or ZF number, right-hand-drive specification, connectors, steering ratio, software, production date and vehicle equipment before repair, supply or fitting.

Bosch and specialist references
Bosch: 7818994946, 7838974465, 7838974763, 7838974421, 7828994166, 7838974761 and 7838974423. Related specialist family: ATGE42191RB/ATGE42192RB. Vehicle and unit identification remains essential because the same broad family also appears in other SPA models.
Volvo Steering Rack Identification
Volvo may use different steering racks within the same model family and registration year. We confirm every application from the VIN, registration, right-hand-drive specification, complete original rack label, connector arrangement, steering equipment and diagnostic information.
Important: similar-looking units and shared base references are not proof of interchangeability. Steering ratio, travel, software, driver-assistance equipment and production changes must be checked before repair, supply or fitting.
Safety first: do not fit or calibrate a rack until compatibility has been confirmed from the original unit and vehicle data.
Common Volvo S90 / V90 Steering Faults
Heavy or intermittent steering
Assistance may reduce, disappear or return after restarting. Power, earth, wiring, communication and the steering unit should be diagnosed before repair is agreed.
Warning messages and fault codes
Send the full diagnostic scan, not only the dashboard wording. Exact codes help separate rack faults from voltage, network, sensor or calibration problems.
Noise, play or notchy steering
Mechanical wear can occur without a stored electronic fault. The rack, inner joints, mountings and connected steering components should be inspected.
Calibration after fitting
Some applications require steering-angle settings, end-stop learning, software or calibration. Requirements depend on the exact rack and vehicle.
Our Assessment and Repair Process
Private Customers, Garages and Trade Welcome
We support individual customers, garages, workshops, vehicle specialists and resellers across the UK. Rack-only repair, reconditioning, supply and fitting can be discussed where appropriate. Most units are covered by our one-year warranty; resellers should tell us the actual sale or fitting date if it differs from the invoice date.
Frequently Asked Questions
Can you identify the rack from the registration?
The registration helps, but the VIN and complete original rack label provide a safer identification.
Will the rack need programming?
Many correctly matched racks do not require full programming, but some vehicles need calibration, coding or steering-angle settings after fitting.
Do you cover new and fully electric Volvo models?
Relevant mild-hybrid and plug-in hybrid applications can be assessed; the new fully electric ES90 is covered separately.
