Did you remove the bearings?

Your bearings will indicate by mileage whether they should be replaced.

The Calibra setup is very old fashioned small diameter and bad design for side loading. Previous comment on the steering knuckle (bearing housing) is important if everything else has been ruled out. These can be deformed by kerbing, even the ball bearings can be crushed and flat sided. If you had the leg off -  for the price of the bearings to be pressed out and new pressed in and if the Calibra was high mileage might have been a good idea if it had to be done eventually.

You will never gauge the bearings wear when they are cold, when cold any movement is a sign of the start of a bearing collapse. As a mechanical engineer you would know that vibration turns to audible frequency that you can hear and feel, if the problem is at 90kmh there is a sound? the frequency of that sound in Hz is the revolutions of what is worn - lets hope it´s not your differential (pinion) which is turning around 3.46 times faster than your wheels. it is a rotational problem you have and not a clunk (which is top mounts)?

I have a rear bearing that starts whining after 2 hours at 60+ mph, just as everything has heated up to maximum. otherwise you would never notice everyday.

So... after some time, coming back to my favorite topic :)

I have replaced the Bilstein shocks with Monroe ones. These are much softer and have improved the ride. Even with 18inch wheels it feels better too.

The one thing I still note now, is that there is a knocking sounf when turning sharp right. This happens mainly in reverse, but can happen sometimes (not always) when driving forwards while hitting a bump at slow speeds. There is nothing audible at any other time.

What could it be?
