KN Drive shaft wear

[tiskev]

Anyone had drive shaft problems with their Kn ?
I am getting a bit of a rumble on lock when coming
out or going into the garage.She has only done 40K
Could it be anything else ?
It has just had a full service and one assumes this
would have been checked ?

I am on my second Kn and both have had the same problem
The drive shaft bearing needed changing on both cars the bad news is
the bearing cannot be replaced separately and the whole drive shaft
needed replacing, both cars were relatively low milage.
Apparently checking the drive shaft is not part of a Porsche service.

Many thanks Luther.
Strange but as i backed up and put her on lock today
there was no rumbling noise .I was telling myself it could not
be worn shafts with 40K miles mostly on long distance motorway
journeys .Sounds like bad and expensive news
Cheers

Could anything else be making a rumbling noise up front ?

I have bought recon shafts in my MINI days anyone heard of them for the Kn ?

I think it was Sherlock Holmes who said something about once you have eliminated the impossible, you should examine the improbable or summat.

As you did not get the rumble the last time you reversed into the garage, is it possible that on the previous occasion you were reversing.....:

• over small children or animals present on the drive at the time;
• through an encampment of anti-capitalist protesters;
• into someone else's garage?

"How often have I said to you that when you have eliminated the impossible, whatever remains, however improbable, must be the truth?"

It's hercuile Poirrot who said that in the ABC Murders AFAIK.

Mr Spock also said it in Star Trek but that doesn't make him the first. I think AC nicked it from SACD.

You may have cracked it Chris
When i drive in i run over the junk but reversing i dont .
I may have to as Mrs to ask Mr. Smart .
Meantime someone out there must have bought recon drive shafts
they have to last longer than originals .....
My Ford Ka is 13 years old and still on the originals

Normal recon drive shafts are ( FWD )available at £ 80 so double it for a Kn at a guess

The drive shafts have started to rattle again.This was after a long run .
It is a bit of a mystery how it comes and goes .As before it started when putting it into the
garage on about3/4 lock .
Anyone else get this intermittant noise ? do you think I am right assuming
it is the drive shafts ?
Would you drive it 600 miles back to UK ?

I do believe we have the same symptoms!

Mines going back in tomorrow morning for further investigating - the good news is the mechanic has now heard the car making the noise!

I also had the big service done two weeks ago

On a happy not took the pig to work today 100 mile round trip and loved it ;-)

Ok Tiskev. Had my piggy on the ramp and checked over again by head tech and gearbox guy. Nothing loose, nothing perished and nothing missing or broken!!

But Its definitely their intermittently and they have heard it happen once. On Rocking (I mean turning by hand) the front center drive shaft, it obviuosly turns the wheels but hey presto a very similar noise can be replicated - so final analysis is slight wear and tear in the joints which when hot after a decent run seems to show up....but only sometimes. The techs said they would not advise to go looking for something by replacing parts. So I'm kinda happier now!!

BTW Porsche across the country are having a open workshop for all Cayennes to be given the once over checkup by one of their trained technicians - Early March I believe the 4th.

Anyone else having or had these noises??

What was your outcome?

Cheers Frutti Pig

Well she is at the OPC again and they cannot find anything wrong with it
I just do not know how it can make such a loud crunching noise and nothing shows up.
Someone else must have had this problem Any suggestions please ?

Hi Tiskev,

Check the "Cayenne forum" on www.rennlist.com

I use it all the time, very helpful bunch and a lot busier than the Cayenne section on here, unfortunately....

 

[tiskev]

Thanks will do that.
Just do not understand why the noise is so acute when it occurs but when cols or just warm
No noise or probs can be found.
It is the same with the ,door mirrors nothing can be done about them unless a ,procedure is
Started ,that could run into hundreds of pounds (sorry for ,the commas the iPad has a diction of its own )

 

[RSGulp]

Just a thought... could it simply be 'tyre skip'?

 

[tiskev]

Well my son collected the car today and it ran home quietly as expected
The OPC swopped the winter tyres and wheels around to no avail.
They could find nothing wrong with it .i know it is not tyres as last tme I got the rumbles
It was on the summer wheels .
Meantime I will make sure I have European recovery on the next run

Article in this month's Porsche and 911 World re drive shaft and bearing replacement, now possible to replace bearings alone and not the entire drive shaft.
