The dealer said the center drive shaft (Part 95542102015) should be replaced in its' entirety since attempts to replace only the bearing tend to fail.
Also while at it, the (2) exhaust brackets (95511122012) should be replaced as well.
The instructional videos online either only show the bearing area of the center drive shaft but not the removal/replacement of the drive shaft itself.
I can usually follow the Pelican photo tutorials well but didn't see one on this.
Is this an intuitive/easy job or does this require a tutorial?

It is pretty straight forward to change. Just have a safe way to lift the truck up. Once you're under there you'll realize its only a few bolts.

Save yourself big $$ and avoid the dealer.

I purchased a rebuilt drive shaft and bearing, which the local Goodyear shop replaced.(2 hr. labor charge)

There was a core charge but excluding that the total cost was approx. $700 installed.

It worked perfectly for about 40K mi., until sold.

What were the apparent symptoms that the car was exhibiting, thus prompting you to bring the car in for service?

If/when I have to do this job, I plan on going the Lindsey Racing/Driftshaft Shop route. Looks to be bullet proof, and the price is right if you install yourself.

2005 V6 vibrates when pushing the RPMs higher. Does it in neutral as well but much moreso while driving. I'm going to change coils and plugs as well.



That says it's for a V8, mine's a V6, plus that one's $700 and the OEM aftermarket ones are going for <=$500

Doesnt sound like a drive shaft at all. Are the vibrations RPM dependent while stationary? Are there any codes?

When you are in neutral and hear the sound is the car moving ?

If the car is stopped when in neutral it might be the coils & plugs as others have said and not the drive shaft. Do the replacement of the plugs and coils first too see.

Mister Quickie

No codes. The more gas/higher the RPMS, the greater the vibration.
However there is even greater vibration while driving and the dealer said the bearing is worn.



I'll do the coils and plugs first but I figured since the dealer said the drive shaft bearing is bad and needs to be replaced I might as well do that too.

Problem is I just learned you need this tool to do it *right*:

Apparently an experienced mechanic can finesse it without the tool but that's not me and at $276 for a tool ... ouch!

PartsGuyGT

Agreed. Skip the dealer. You can buy brand new GKN OEM ones for about $400. At my work we sell them to shops for about that much. (Not trying to advertise. I run a European parts store in CT).

ECS wants $537 for GKN but that includes the remounting bolts which are invaluable since they tend to rust/break so it's nice to replace those.
The $276 for the tool.
They do have free shipping though.
Do you sell a package of the shaft, bolts, and tool and if so how much?

Andy E.

Standing still and in Park or in Neutral? If so, the dealer is not God and either may be wrong (won't be the first time) or may be very slow at this time of year and needs the work. Have you tried bringing your Cayenne to an independent mechanic for a second opinion? I would also advise against telling the Indy what the dealer said and have him figure it out for himself...

See above as far as "what the dealer said..."

Try the "jimi fix" first.

Vertex assured me that no special tools were required. They guaranteed their assembly without it.

It was not used for my repair.

That dealership is either incompetent or a crook.

That shaft bearing will cause a thumping sound right under your elbow if your arm is resting on the center console, and at first it will only do it when you're hard on the throttle.

The RPM of the shaft is only related to vehicle speed, not engine RPM. At rest in neutral the shaft is not spinning, so there is zero likelihood of it being that.

Even if your vehicle did have a bad shaft bearing, the dealership will not suggest or install an aftermarket product without a blessing from the fatherland.
