Hi, my mechanic, after fixing up a whole host of issues, has also found that rubber support mounting for the carrier bearing of my main 2 piece propshaft needs to be changed. He contacted the Jaguar dealership for a replacement mount and they told him that this is only sold as a complete unit together with the entire main propshaft. Can anyone tell me if the rubber mounting is available as a separate unit for replacement, without having to change the whole propshaft? Thanks

 

Found this, I think it explains everything.

Thanks for the link. If this is the reason why, then it's a real bummer as it would mean a new driveshaft every so often (another expensive consumable item like the air suspension....) when other cars just have to have the support bearing / mounting changed. When I checked, a new driveshaft is going to cost 685 Sterling excluding freight..... sigh....

Sounds like a possible business proposition for aftermarket carbon fibre driveshaft manufacturers, with a one piece driveshaft or a two piece with a replaceable support bearing...

 

Sorry for the less than anticipated news, but just because there is a certain procedure and/or parts limitation, does not mean there isn't any other option available. A new throttle body was the only way to replace the pedal position sensor on my xk8, yet within the least few months, members have located the individual sensor after much investigation and research. The microswitch that was once only available by purchasing an entirely new door latch (about 2 years ago, and same car) can now bought separately...even Jag started offering it. All jag is saying is they don't want to take the time to separate the entire driveshaft for those individual parts, for one reason or another. Like that jurid coupler up front...for my MY it doesn't show any separate parts, yet on the 1997-2002, it does. And I am fairly confident that this same coupler can be used up to 2006, as I found one source that listed it as such (in the UK) If your mechanic is good, he may be able to locate or find another model that uses the same part, but the current dealer parts catalogue and parts counters cannot locate to sell.

 

Yes that's true, but it would be difficult to source for one without having the car laid up for a significant period unfortunately (The car is driveable currently and only makes some vibration noise during hard acceleration). I'm now trying source for a used one to see if it can be used as a sample. In the local context, finding an alternative is likely to be problematic as Jags are rare and spare parts for Jags are also hard to come by ex-stock for comparisons to be made. This, of course, is one of the reasons to have forums like these to see if anyone else has a past experience that they can share, but I have a feeling this particular issue will be more peculiar to topical countries at this stage as the rubber parts of Jags seem to self destruct at a much faster rate than in temperate countries.

 

I was talking to my local Jag dealer about some other parts today and asked about the drive shaft. It is the same in the XJ8 and XJR. One part number including the flexible coupling at trans to flexible coupling at diff.

Seems like the couplings and bearing should be aftermarket available.Yes I know they say it's a "refined" complete balanced unit. I'll give them that as it makes sense. But I can't see a bearing being off even slightly or rubber couplings that poorly manufactured.

 

I'm wondering if just shimming the center support bearing about 1/16 or so wouldn't tighten things up and make it run true again?
may even be doable without removal of mufflers, etc. Ask your tech.
Just thinking this might work.

 

That's what I thought but some of my local mechanics feel otherwise as they've seen harmonic oscillation of the driveshaft cause full separation of the shaft joint resulting in total destruction of the car (not a jag) as the car somersaulted at high speed, somewhat like a pole vaulter, so they're a bit wary.

BTW, how did you like your Europa? ?5 Speed. I used to have a +2S130/5

 

Access to the shaft requires dropping of the exhaust system unfortunately and shimming (and gluing) the shim in place may be involve quite a bit of guesstimation, which of course can lead to eccentric positioning, with all the associated potential vibration problems, which may be risky. I think it would be safer to either replace the entire bearing/mount. The only problem is that these seem to come with a driveshaft attached, which is either expensive if bought brand new (last checked approx US$1600) or if used, potentially has shipping issues due to size.... sigh....

 

You're right.
Guesstimation is not good.
Especially with hard, rotating parts like these.
Guess I will drive mine at speeds where no vibes occur.
Can't see wasting all that money for only a slight improvement. The rubbers and mounts and couplings are fine.
I'll go for a new set of hankooks and a road force balance and see what happens.

 

By the way, can anyone verify what is the correct part number for the complete propshaft for the 2005 XJR. I have been told the part number for my car's propshaft C2C 35603 but other numbers have come up on the net as C2C 39452 and C2C 24807 and I wouldn't want to pick up the wrong prop-shaft. Thanks

 

Realise i'm a little late to the party here, but I got a kick start to look into this issue because of another thread here on the forum https://www.jaguarforums.com/forum/x...85/#post761706

So with a bit of investigation, I think that the rubber flange coupling from the S-Type will fit the X350. P/N C2C12747, these are the same for the front & rear connection between the gearbox & propshaft, and the propshaft & diff.

The flanges at the transmission & diff are the same for the S-Type & X350, makes sense that the couplings will fit too. Still looking for the center bearing mount, that is not listed separately for the S-Type...

P.S. the rubber coupling C2C12747 is £64,77 list price +VAT in the UK

 

Prop shaft not man enough for 400BHP xjr?

They told me they never see Aluminium XJ's -not many around and too reliable!
