Have a couple questions I hope some of you can help me with. Been getting a high pitched noise that sounds almost like a tea pot or something after starting the car and driving it in the mornings. Only get the noise after the car starts moving. Could this be the engine belts? If so which ones and how often are they supposed to be changed? I greased the proptshaft bearing this summer. Ive read of a lot of people getting that cold whine. Could that be it? I opened the hood and tried to listen but like I said only when the car is in motion is it that I hear the noise. The last things I did to the car was replace the radiator and an oil change. Any ideas?

 

If it goes away once everything is nice and warmed up, there is a good possibility it is the prop shaft bearing. Some folks find relief by greasing it with a needle fitting on a grease gun. Several posts about it. Search This Forum button is our friend.

 

Thanks for the response but like I said before I have searched the forums and read about this cold whine coming from the prop shaft and I applied grease to it. I had kinda ruled that out because the sounds are different compared to what others experiencing the same issue have said. The sound starts off like if someone was holding a balloon filled with air and slowly real easing the air, a high pitched squeky sound. Then after driving a little bit and accelerating it gets louder like a tea pot. Best way I can describe it...I will try and upload a recording and grease again. Any other suggestions?
Thanks again

 

Does it sound like mine?

 

I thought the whine on my car was the propshaft bearing but turned it was the transfer box instead this is quite distinctive it usually only happens in cold and only over a certain speed, it was 3 years before I worked out what the problem was as everyone I took it too didnt seem to have a clue. Anyway it would be worth considering.

 

Thanks for the reply Aonsaithya my sound is similar except it is a higher pitch and squeakier. At least that's how it starts then goes into a full howl and gets louder. So is the prop shaft at fault? Here is my recording
Jagman thank you for your reply I also have taken my car to two different shops (a dealer and a jaguar specialist) and they couldn't tell me what the noise was either. Although the jaguar specialist did tell me he thought it was coming from the transfer case but couldn't give me a sure answer. The dealer said they couldn't replicate it. If it is do you think changing the fluid would help? I was hoping it wasn't something this serious. Thanks again

 

I've no idea. The independent shop I've visited said they've spent tens of hours diagnosing these issues and they've pinpointed the sound source to be that carrier bearing, but that most of the time at least swapping the bearing did nothing to the sound. They said they suspect it's resonance from elsewhere in the drivetrain that causes the bearing to make noise.

Currently, unless it's really cold, mine stops making the noises after about 500 meters or so.

 

Hard to tell from the video, but if the noise starts at between 28-32MPH I would almost guarantee you it would be the propshaft. If it starts as soon as the car moves then it would be something else.

 

From what I've learned over the last couple of years changing the fluid is not possible, apparently it's a sealed unit? There is a guy in the US that has made a tool that allows the fluid to be changed he does sell them but I cannot find his details? Most people I have spoken too about this have all changed their transfer boxes to eliminate the problem once and for all and that will include myself as I have this planned for coming months when the weather warms up. Sorry not good news but its just one of those things when you have the 4x4 X type. Just to add I was told it was my propshaft as well but after ordering the special grease needles from the states and actually doing the job didnt make any difference to the noise. Not saying dont try it just dont expect miracles. Good luck

 

Changing what fluid? I've had the transfer case fluid changed, it's just a bit complex as you need to take it somewhat out of the car.

Changing rear differential oil is also possible, just requires a vacuum-something as there is no drain hole. I had that changed a few weeks ago.

Both are standard maintenance procedures on these cars...

EDIT:
A non-full TC fluid change doesn't require taking the TC out of the car.

 

So, we gave out 2003 X-Type to our 16 year old daughter for her birthday in May. Today she told me she has this whining noise when it's cold. We went for a test drive, and I could hear a noise briefly that sounds like the video's above.

We had the driveshaft (or propshaft as it's called across the pond) replaced about 10 years ago when the Universal Joint boot failed and spewed grease into the exhaust pipe braided pipe, causing smoke and smell, at a cost of $800 US.

This video here makes it look pretty easy to do..



RockAuto.com has a "Differential Bearing" available, but it doesn't look right.

Does anyone have a source (and replacement procedure) for the carrier bearing? Or is the "Grease it with a needle on a grease gun" method the accepted procedure?

Thanks everyone for all that you do...

Doogie

 

I'd try the "Grease it with a needle on a grease gun" method first.

Here is a thread from 4 years ago that I book marked for future reference. I don't know if the links are good but it gives some info.

Welcome to one of the "peculiarities" of owning an X-Type!

Mine is a SCREAMER at times when it is very cold, the humidity is just right, and the moon and stars are aligned with cold. At most it will last about 2 minutes, never to return for the day.

Through the years I have noted that just about every X-Type owner on this forum has had this complaint, if they live in a clime that gets cold enuff.

Methinks it is just that our beloved kitties really, really prefer a warmer day.

It does not seem to portend the failure of any particular part, and for the most part, can safely be ignored.

Yes - you can chase it down and fix it.
No - it is generally not worth the effort.

Kitties are wont to complain about the cold. My 'real' kitties complain lately much louder that the Jag (-38f chill factor). Keeping (either) inside (garage the Jag) is the cure. The take-away message is that it is too cold to be driving around, mostly.

It doesn't seem to hurt anything, other than the ears for a few moments.

(at least it isn't a rattle!)

 

I think your problem is little or no fluid left in the transfer case. This is a slam-dunk X-Type issue, and you'll find beaucoup threads on how to fix it. Jaguar made changing TC fluid a PITA, then covered their tracks by calling it "lifetime fluid." To me "lifetime" means "until the unit fails, then please ring us up to set an appointment for this very expensive repair." By the way, Jaguar also says ATF and diffential lube are "lifetime fluids," to which many members here say "Hogwash." Pictured are my products of choice for engine, transmission, TC and differential.
