I have a 2001 Catera base model (I believe equivalent to an Omega B Saloon Model 3.0L V6) with about 160,000km or 100,000 miles.
I have lately started noticing a clunk noise when I shift from park to reverse and then from reverse to drive, normal backing out of one's driveway.
Do the Cateras have a Universal joint or yoke assembly that can be replaced as I was told my universal joint may be going?
I have searched compnine.com and rockauto as well as acdelco but cannot find a part number.
Any help in comments as to the following,
- Safety or driveability wise how serious is this issue
- Fix suggestion with part number (Vauxhall number is OK) if possible please
- Is it a home repair for a hobbyist some some tools with jack and jack stand
Regards and I will be happy to clarify if it is not clearly described. :-[

in true omega tradition, a thump when engaging drive means time to service box fluid, but a clunk implys metal on metal banging type noise...?

I had the rear drive wheel on a jack today free and clear. When I moved it I could hear a play type noise from almost under the middle of the chassis.
Thanks Chrisgixer for quick reply.
I am planning to do the Transmission and differential oil change. What you call the box in UK (Transmission or differential), I know it has other connotations as well ;)

automatic gearbox, autobox, box (Transmission)
rear differential, rear dif, dif. (differential)

Thanks again.
So the noise I was hearing when I turned the rear driving wheel back and forth when on a jack stand could it still indicate the box, differential or did they use something like a U-joint in the main drive shaft assembly.
Cheers. :y

Prop shaft has a UJ on it but cause little to no trouble.
There is a centre rubber mount with bearing in it so worth checking that for damage but again, not prone to issues.
I would be checking the gearbox fluid levels etc and checking rubber mounts (gearbox, diif and engije) for excess play/damage

On my last car the gaiter / seal on the splines in the centre of the prop shaft had disintegrated allowing the splines to dry out and wear.
The symptoms were exactly as you described. (though the car was a manual [stick shift?])
It was still running fine at 200,000 miles (when the rust got too embarrassing to ignore) but I should really have greased the splines and fitted a new gaiter.

DTM, chrisgixer and Andy H I thank you greatly.
I have saved this thread and I will go through all that both of you suggested. I am budding hobbyist trying to learn this car as I kind of like it.
I will post as appropriate whatever turns out to be successful resolution. You guys across the Atlantic really know a lot.
I am very happy for the answers and time you guys gave.
Regards. :y
