It’s all too easy to get a steering rack delivered that doesn’t fit. Make a few simple checks before ordering a replacement.
Check the Mounting Bracket Positions
Check the location of the mounting bracket positions on your existing steering rack and take note of whether the bracket sits above or below the main body of the rack. These dimensions can vary between different model years, even for the same make of car.
Note the Tie Rod Configuration
Are inner tie rod ends threaded or is it a clip in design? Also take note of the thread size where applicable, as early and late models of the same car may have different steering racks, particularly electric steering racks.
Confirm the Connector Type and Pin Count
Check the connector type (e.g. ISO 11745, 6-pin plug) and the pin count for the motor and for the torque sensor. A plug with a different number of pins cannot be modified in a safe manner, since different markets (e.g. LHD vs. RHD) can have different connectors on the same model.
Check the Shaft Spline and Input Length
Also check the length of the input shaft of the steering column and the number of splines. Even a difference of a few millimeters or a few splines will mean that the steering column cannot be fitted correctly. These parts are approved for vehicles and must therefore be fitted correctly.

Measure the Overall Rack Length
Compare the overall length of your current steering rack (end to end of the tie rods) with the specification of your replacement part. Even a few millimeters difference can affect steering geometry.
It is so much easier to get these few checks right before you order rather than having to return the steering rack.
