• How can I change driveshaft centre bearing on a 2004 BA Falcon?

  It sounds very much like a seized bush in the rubber-donut assembly that joins the tailshaft to the back of the gearbox. Inside the rubber donut (also called the flex-joint) there’s a metal inner bush and these have been known to seize. Water gets into this bush and rusts the assembly solid. If that happens, it will feel like the thing will never come apart.

  At that point, perhaps removing the slip-yoke from the back of the transmission will allow you to remove the whole assembly and get better access to it on a bench, rather than from under the car. The slip-yoke shouldn’t present any problems other than you might lose a little transmission fluid (so have some rags handy) but you do need to remember to mark the position of all the components relative to each other. That means marking where the tailshaft bolts were relative to the rear coupling, the coupling relative to the flange, the shaft relative to the yoke’s holes and so on. That’s so when the tailshaft is reassembled and refitted, it’s still in balance and won’t create any new driveline vibrations. This process even extends to marking which nuts and bolts attached to which mounting holes in the rear CV joint, as some of these bolts were individually weighted for balance.

  The other thing to check is the actual centre bearing you’re trying to replace. For some reason there were two different part numbers for this series of Ford Falcon. One has a different bearing inner diameter and a different spacing for the mounting holes compared with the other. Make sure you buy the correct one.

• Ford Falcon: Indicator failure

  When a globe in one of the indicators goes out the other indicator on the same side as the one that has failed will flash quickly. At the same time the indicators in the instrument cluster will flash quickly and the audible indicator will click quickly. Turn each of the indicators on and check that they are working. If they aren't it suggests a deeper problem, which could be a fault with the cluster. One thing for sure it won't fix itself. If you want to get a second opinion take it to an auto electrician.

• Ford Falcon 2004: Noise over small bumps

  It's not possible to say with any certainty without inspecting the car, which is what you should have done. But on what you have told us I'd be looking at the suspension bushes and shock absorbers in the front-end.

• Ford Falcon 2004: Shuddering

  I suspect you have a vacuum leak, probably caused by a cracked or split vacuum fitting on the brake booster.
