Rattles and Vibrations

A common rattle, just as you pull away (it sounds hideous and tinny) but is often not the propshaft, just the heat barriers that are bolted to the body up above the prop. The bad news is that to correctly fix this, you have to take the prop and the exhaust off, then take off the heat shields and then bolt them back on firmly with no guarantee this will cure it!!! a bit hit and miss, but the only way.

The Trekka uses a Nissan derived hydraulic coupling rather than a viscous coupling to transmit drive to the rear wheels.  If the front and rear axles rotate at different speeds this causes a hydraulic pump to actuate a set of mini brake shoes within the coupling to lock the two axles together restoring drive.  The Scenic RX4 used a conventional disc/silicon fluid viscous coupling.

 

One of the big problems is owners who only replace a pair of tyres (usually fronts only) which creates a constant difference in axle speeds and eventually overheating and failure of the coupling.

 

Always replace all four tyres at the same time to avoid damaging the coupling.  Typical symptom is a sort of metallic rattle from the coupling when turning on full lock. Very noticeable in a multistory car park and may be accompanied by tyre squeal if the coupling has seized.
