Steering finished

Finalised power steering The picture above left shows the ecu for steering. this comes bolted to the column but has to be removed and fitted elsewhere. I have tucked it up above the pedal box on the outer footwell panel but this meant that the short loom back to the column torque sensor had to be extended. The picture on the right shows the speed control unit – this little box is connected to an independent speed sensor located at the diff UJ and effectively controls the maps for speed sensitive power steering assistance variation I will be able to fine tune this once the car is moving. As a side note I am also working with Dave at Canems to hopefully make this box redundant since a modification to the canems ecu allowing it to collect speed input data is eventually going to enable direct control of the power steering maps and the tremec reverse lock out solenoid.

Power Steering Column Fixed to Body

I have bolted the power steering column end to the body with a simple u clamp type arrangement this has a fairly substantial backing plate on the underside. The  blue tape is the position for my bonnet lock down keep brackets.

Finally fitted the ujs and shafts down to the steering rack and was able to power up the unit – very pleased the steering feels excellent very smooth and silent whilst in powered mode!



Power Steering

Eventually got round to making more progress on the power steering installation. After a couple of trial fits in the car and lots of measurements I am now very happy with the position of the column. The top left picture shows the replacement cross member – this replaces the GD cross member due to structural and geometry requirements. as well as substantially beefing up the mounting bar and the side fixing plates it has to lie in a slightly different position to accommodate the power steering. I chose to mount the power steering to a top hung bracket so the columns collapse mechanism can operate as intended in the Oem installations (hope i never get to test that out though)!

Once installed everything fits very well and the wheel position falls in the correct place.dsc_0065

only just fits in – but im happy with “Only Just”. Notice the little bracket on the square section bar with two holes – these will take further reinforcement straps fixed down the side of the body tunnel adding even more rigidity to counteract the torque of the motorised column.

New wiper motor mount cradle required. and new demister vent fabrication to allow for glovebox.


The column on the engine bay side. A new bracket will be fabricated to fasten directly to the body at this corner location Rather than fasten it to the GD chasis. This should work  well since it means the uppermost column is attached entirely to the body, with the lower part of the of the column attached to the chassis. The next section of column incorporates a splined slip joint, so small movements between body and chassis will be taken up in this joint.dsc_0042

Final Check that wheel sits nice and square to the car and approx 120mm back from the A post shutline.
