Autodata Technical Issue 20 – Knocking noise from the front of 2006 Vauxhall Antara

31 October 2018

Each month the Autodata team answers a common technical question and provides a printable document with technical diagrams to download and keep, exclusively for IGA members. This month, a 2006 Vauxhall Astra has a knocking noise coming from the front end when manoeuvring.

Q. We are having difficulty finding the source of a knocking noise from the front of a Vauxhall Antara which mainly occurs when manoeuvring or parking. We have checked all of the steering and suspension joints but can’t find any excess wear. Have you heard of this problem? The car is a 2006 Diesel model and has covered only 45,000 miles.

A. Yes, this has been reported by other Antara owners and occurs as a result of insufficient lubrication of the steering column lower shaft sliding joint. Remove the steering column lower shaft and pull back the rubber cover (Fig 1.1).

Using a suitable tool insert 7ml of silicone oil into the steering column lower shaft via the breather hole (Fig 1.2). Slide the steering column shaft in and out about 10 times and ensure that it slides freely. This should cure the problem. Refit the steering column lower shaft and carry out a road test.
