I took the 2011 XKR175 to the dealer for its six-year/90K service (40K miles on the odometer) and was told that the rear struts need replacing. It's a warranty item (thank you CPO) but still, 40K miles seems like a very short lifespan for a set of struts.

But what do I know about Jaguars. Is this normal?

BTW: The dealer burst my bubble a bit. This is the San Francisco area, and this one dealer has serviced four XKR175s in the last month, all except mine owned by football/basketball/baseball stars he says. I thought of the XK as more James Bond than Footballer, but I guess I was wrong about that.

Oh, and the service cost $840, which seems reasonable for this area. The next one is supposed to be more expensive though.

 

It does seem like an unusually short service life but I guess every so often these things happen.

 

Yes, very normal. There are quite a few threads on here about cars (mine included) needing full suspension rebuilds under 50,000 miles.

 

+1 mine shot to pieces at the 55k km mark.

 

And now I find out that struts are a wear item not - as originally quoted to me - a CPO warranty item. The technician states that one of the struts is leaking. So I think that I will get a comparative quote from a very reputable Jaguar-specific independent.

 

Yes, OEM green struts are available on eBay for fire sale prices.

Per the failure I sincerely think most wear on these cars comes from sitting. It's hard on rubber components which need exercised to live.

 

Does anyone have a reliable way to determine the part number for rear struts given a VIN? There appear to be several different options available, ranging from $100 to $555 - all for brand new Jaguar struts with CATS but with differing part numbers. I am hoping that C2P17674 is the magic part number, because eBay has a great deal on those.

 

40,000 is ridiculously low mileage for shocks to start leaking, but I guess it's possible. I replaced all four of mine at about 110,000 miles when the ride started to degrade and noises were apparent going over speed bumps. I purchaed Jaguar XKR oem shocks from British Parts Place on ebay, all four for $349, I believe. That is less than the cost of one shock from Jaguar. These were CATS suspension original equipment, Jaguar stamped shocks. The 2011 shocks are the same as the 2010. The parts number changed in 2012, I believe. I will look back and see if I can find the specific part number, but I researched it extensively before I ordered.

 

Here is what I purchased and is still available from the same vendor.

And by the way, even though it shows on the compatibility chart only the XK model and not the XKR, if you check with the Jaguar Parts Catalog, these are, indeed, the part numbers for the 5.0L XKR models as well. I did the research before I bought, called British Parts Place, and informed them that these were the correct part numbers for the 5.0L XKR.

 

My worry is that these mention "CATS" and not "Adaptive Dynamics". The 2010+ X150 manual declares a big distinction between the two.

 

j.w.s
You need not worry, take a look at the following two pages from Jaguar Parts Catalog and you will see that these are the part numbers for ALL 2011 XKR models. Period!

You might also take a look at the price for EACH Shock, $432.90! Multiplied by 4=$1731.60 vs. $349.00!

 

Well if I look at the Jaguar Reno site you reference, the part number for the rear is C2P17674. That is the magic number! eBay has them new for $200 per pair from British Parts Place!

Yes, I know that is the number. I sent you the link for all 4 shocks (fronts are C2P1760) thinking that if you're replacing the rears, then you might consider replacing the fronts at the same time since the fronts tend to wear out first. An independent Jag mechanic can replace these fairly easily, so you should be able to save yourself a couple of thousand dollars. By the way, it was a pleasure doing business with British Parts Place. They shipped promptly and sent exactly what they presented.

 

Based on your find, I am thinking of getting all four - I'm sure I'll need them eventually. And talk about an enormous savings!

My out-of-pocket for replacing the rears has gone from:

$2,700 - dealer parts and install
$1,600 - dealer parts and independent install
$600 - eBay new parts and independent install

I'm going to confirm the part number with the independent jag installer tomorrow, but this is pretty darn good news to me.

 

You can also get aftermarket Bilstien shocks that will work with the adaptive dampening system from summit.

 

You can go to www.parts.com and type in your VIN, then search for the parts, guaranteed to fit AND work as designed originally this way. It is a great source for genuine parts at big discounts.
There are way to many counterfeit parts on Ebay and Amazon. Beware.

 

There are lots of different ways parts wear.

For rubber, time(aging), use, and prolonged lack of use(Extreme aging).

Luxury cars, trend to softer/quieter suspension materials. These age out faster, and wear out faster. They also make for a quieter car. They figured the replacement time is worth the quieter vehicle. (It is.)

Environment has a lot to do with it to.

 

My 2010 has 61,000 and I've never let it sit longer than three months, and only that a few times due to cold and snow. I had all my struts and bushings checked last autumn and they were all perfectly fine, and original.
