If your Sera is experiencing power on / power off steering problems, then it is likely that the lower wishbone bushes have worn. This is something that can be done by an amateur with an average toolkit.
PARTS & TOOLS REQUIRED:
Jack & axle stands.
Socket set (with long arm for extra leverage)
Loosen wheel nuts, jack car up and remove wheels.
Remove anti-roll bar – 12mm nut. It would be best to do this at both sides which will allow the anti-roll bar to turn freely along its inner mounting points.
Undo bottom ball joint – 2 x 13mm nuts and 1 x 13mm screw.
Remove front lower wishbone mount – 17mm bolt
Remove rear wishbone bush bracket – 2 x 17mm bolts.
The wishbone should now be free and can be removed from the car. Then continue as follows:
Replace wishbone and replace all items, including antiroll bar, but do not tighten fully. Put wheels on temporarily and bounce suspension a couple of times.
Raise car, remove wheels and tighten all mounts fully.
Refit wheels & tighten as normal.
- Test drive
After the test drive I would recommend checking all mounting points.
