Electric Power Steering Knock

Electric Power Steering issue on Hyundai 2009 with 60,000kmHyundai i30

Recently we had a customer come in, frustrated that they had been to 4 other workshops to fix the knock in the steering. The knock was present when you turn the steering wheel from left to right or right to left. The car owner either didn’t receive a convincing explanation or a solution from the other mechanics or the other repairs didn’t know or want to know about the issue the car was having.

Vehicle – Hyundai i30 2009 model, which had done 60,000km

Fault – The steering had a noticeable knocking when turning left and right, you could feel it through the steering column.

Cause – The flexible coupling within the electronic power steering motor has completely failed and was causing slop in the motor.

Remedy – Removed dash panels, removed steering column assembly. Dismantled the power steer motor assembly, replaced the coupling and reassembled steering column in vehicle.
