cayenne diff problem??
hi all,
i had a noise coming from what i thaught to be the right front wheel bearing so changed it,
noise was still there so changed it again.......
still there so changed the drive shaft.......
still there so changed the discs and pads as they were on there way out anyway.....
still there so im starting to think it may be the front diff?
has anyone heard of any diff problems on cayenne's? it is a 4.5 cayenne S.
thanks alot.

I haven't heard of any problems with the differential.
Throwing parts at this issue sounds like an expensive way to diagnose a problem. Might be time for a trip to the mechanic...

Any metal particles in the oil?
If you are correct and based on the sounds/feel, I would imagine by now there are metal particles in the oil.

Clearly one of the weirdest threads to date. Based on the first post, some of us could only assume that this vehicle had been carjacked, or otherwise stolen. Thus the lack of initial responses. It takes only a passing knowledge of English to understand why, so I won't explain it.
Now the problem is that although we seem to be speaking English for the first time, we are missing some information. Reading between the lines, it seems that you are saying that the noise is related to vehicle speed, and not engine RPM. Are you SURE that this is the case? When can you hear it best? When braking? (I mean, uhh, "breaking") When turning? Do you hear it when you are idling near a wall with the window down? It would be helpful to know under what conditions you really hear this noise clearly and then the best description you can provide as to what it sounds like.
I really doubt that there is any "major" problem that can be traced back to VEHICLE speed. Problems, maybe. But killer problems, unlikely. It's more likely to be related to ENGINE rpm and could be just a belt, although it could be a semi-expensive accesssory (uhhh, I mean "Axsessorie")

definatly a speed related noise, had the car on a ramp in drive and all the wheels but the left front turn, there is a noise coming from the point the drive shaft goes into, like a knocking sound, only heard this with a stethescope.... (excuse the spelling once again)!!!

Wheels off the ground the diff will make all kinds of noise as there is nothing to hold preload on the gears. You have to remove the psm relay, then run it up in a high gear, and have to l hold 100% steady, other wise your chasing ghosts

Just a guess here...... Now you mention a popping noise when turning...... This is usually associated with a CV joint.
Did you look at the front outer shaft boots and see if they were clean and dry? If not, then you may have a CV joint going bad. I've never heard them "grind" but the popping is consistent.

I have seen one or two differentials making a bearing type noise, due to what turned out to be the bearing on the outer drivers side of the differential, just inside where the C/V axle would mount.

is this a replaceable part then or will it be a new diff?
