Tocking rotational noise coming from right side wheel...?

[Miles Monroe]

Could this be something to do with the CV Joint or wheel bearing...i originally thought something might be trapped between the disc and guard but sounds more mechanical.Any thoughts...?

Front or rear - CV joints are only on the rear.

CV joints are usually a lower (bass like) sound - usually on first forward or first reverse.

Wheel bearings are usually higher pitched and can be varying due to vehicle speed.

Sorry...yes the rear.It makes the sound when rolling.Sounds like someone tapping on the wheel with a block of wood...

Have you checked the tire for road debris?  I know that is really simple, but I have had rocks stuck in the tread that makes the same noise.  Also picked up a large bolt one time.  Stuck straight in and I could actually feel it when rolling.  Ruined the tire.

Been rumageing underneath this afternoon & it sounds like the infamous inner CV joint clunk (O/S).So now i guess its a case of a new joint/boot or the full axle assembly....and whether i can fit it without a nervous breakdown.If i fit a new shaft unit will i have to remove the exhaust or wheel hub for clearance.

On your Boxster, you can remove the axle assembly without removing the hub or exhaust system, but it is a bit "fiddley".  Partial removal of the exhaust on the affected side will give you more room.

Thanks....the cv joint + bits & full shaft assembly look like Porsche only parts.If i decide to go for just the joint is it essential i get the Porsche sealant to "glue" the cover/lid on to the joint...?Why is it so expensive for a tube of said sealant..?

Just about everything Porsche sells is grossly over priced, but is also often found in the aftermakret for considerably less.  Shop around and look at online resources as well.

Cheers....by the way are outer cv joints as prone to failure as the inner..?

I understand these are totally unavailable and cannot be separated for replacement on the driveshaft.
