Over time, steering racks are susceptible to wear, which can result in leaking seals from where the tie rods exit the sides of the rack. If your steering rack starts leaking, it will be readily apparent due to the puddle of power steering fluid under the car and the increased effort required to turn the front wheels. Unfortunately, the rack itself is non-serviceable for the common DIY mechanic, due to the specialized equipment needed to replace the seals in the system. The entire rack must be replaced.

Removing the rack is a bit of a chore. You'll need to jack up the front of the car and support it on jack stands, drain the power steering fluid and remove the front subframe beforehand. See our articles on Jacking Up your C30, Power Steering Pump Replacement and Front Subframe Removal for more information.

Left and right sides of car: Loosen and remove the 13mm bolt (green arrow) holding the steering rack to the front subframe.
Figure 1

Left and right sides of car: Loosen and remove the 13mm bolt (green arrow) holding the steering rack to the front subframe. Now remove the front subframe. Please see our article on Front Subframe Removal for more information.

Once the front subframe has been removed, place a floor jack underneath the steering rack in the area of the green arrow.
Figure 2

Once the front subframe has been removed, place a floor jack underneath the steering rack in the area of the green arrow. This will support the rack in place while you disconnect the fluid lines and steering column.

Loosen and remove the T30 Torx bolt (green arrow) holding the power steering hoses to the left side of the power steering rack.
Figure 3

Loosen and remove the T30 Torx bolt (green arrow) holding the power steering hoses to the left side of the power steering rack. Just let them hang free for the time being.

Loosen and remove the 10mm bolt holding the securing plate to the right side of the rack.
Figure 4

Loosen and remove the 10mm bolt holding the securing plate to the right side of the rack. Remove the plate and pull the lines out of the rack. Have a drain pan below to catch any fluid that leaks out.

Now pop the lines out of the plastic clips below the rack (green arrows) and set the lines carefully out of the way.

Now pop the lines out of the plastic clips below the rack (green arrows) and set the lines carefully out of the way.

Locate the steering column coupler on the floor of the car.
Figure 6

Locate the steering column coupler on the floor of the car. This is held together with a single 8mm bolt. You'll want to mark the connections on the upper and lower shafts for when you reassemble the coupler.

Shown here is the coupler disassembled.
Figure 7

Shown here is the coupler disassembled. You'll notice the flat spot on the lower shaft (green arrow) to help orient the coupler during reassembly.

Now carefully lower the steering rack out from under the front of the car.
Figure 8

Now carefully lower the steering rack out from under the front of the car. Be sure to pull the rubber boot (green arrow) off the rack and transfer it to the new one. At this point, you're ready to install the new rack in place. Installation is the reverse of removal. See our article on Power Steering Pump Replacement for information on adding new fluid and bleeding the new rack.
