Hey, mine had started to wine. I'm in canada I searched over and over looking for gears etc. Nothing. I could only change the bearings and crush washer/ seals.
I couldn't find the crush washer preload settings, rebuilt it 3 times, then swapped in a used differential from the US. Traded it in never to look back again.
My car had about 110 000 kms when I traded it in.

Here's the simple reason why.
They used a ford differential body. But then made the ring gear .5 inches smaller. In turn these cars are the only ones using these ring gears. So no body decided to help it along.
The failure is from the cleaning process from the differential builders.
The best fix to date is to get a differential off the older jaguars, a good jaguar mechanic can do so but still is costly.

2009 Jaguar XF supercharged rear differential replacement what are my options?
Part 1, part 2 will come when we get to it...
For those of you trying to get your head around which diff is in which car….
Differentials in the late model Jags;
X200, S-Type pre-facelift
X202, S-Type post-facelift
X250, XF all models
X150, XK & XKR alloy body
X350, XJ alloy body
X358, XJ alloy body facelift
X351, New XJ
X152, F-Type
Note that the “Gen” naming is not official and is carried on from the Gen1 & Gen2 nomenclature
Gen1
Ford / Visteon 8” unit, used in the S-Type and the Lincoln LS (also Thunderbird)
Equal length driveshafts, symmetrical diff housing
X200 S-Type, up to M45254 (2002MY)
3.07:1 (manual trans)
3.31:1 (automatic)
3.58:1 (Mexican models)
No LSD option from the factory, but the regular Ford 8.8” center bolts in without modification.
Some X202 S-Type owners have fitted the Gen1 housing and driveshafts, along with a Ford LSD.
Gen2
Here you see a Gen2 on the left, Gen1 on the right.
Ford / Visteon 8” unit, used in various models
Unequal length driveshafts, offset diff housing
X202 S-Type, from M45255 – N52047
X350 XJ, up to H31470
X250 XF, up to R41865
X150 XK/R, up to B32752 (3.5/4.2L only)
2.69:1 (2.7D manual)
2.87:1 (4.2L in XJ & S-Type)
3.07:1 (2.7D auto, 3.5L XJ, 2.5+3.0 petrol manuals, XF 4.2 S/C)
3.31:1 (2.5+3.0 auto, XK/R 4.2 [S/C & N/A], XF 4.2 N/A)
No LSD option from the factory, only aftermarket solution is Quaife ATB (Ford 8.8” doesn’t fit)
See as per Gen1 section it may be possible to fit the Gen1 into a Gen2 car but you need to change the driveshafts and also the ratios.
Gen3 Non E-Diff
Complete re-design, internals TBD
Different flanges & driveshafts to previous generation
X206 S-Type from N52048
X358 XJ from H31471
X351 XJ from V00001 (2.0L, 3.0L N/A, 3.0L Diesel, 5.0L N/A)
X150 XK from B32753 (5.0L N/A only)
X250 XF from R41866 to R47153 (all XF engine options incl 4.2 S/C) & from R41754 (all non-S/C)
X152 F-Type from (3.0L S/C non-S)
2.69:1 (2.7D manual)
2.87:1 (4.2L in XJ & S-Type)
3.07:1 (2.7D auto, 3.5L XJ, 2.5+3.0 manuals, XF 4.2 S/C)
3.31:1 (2.5+3.0 auto, XK/R 4.2, XF 4.2 S/C)
The F-Types without E-Diff are;
3.15:1 V6 non-S, 8-speed (open)
3.31:1 V6 non-S, 6-speed (open)
3.31:1 V6S, 6-speed & 8-speed RWD (Torsen)
No LSD option except for the F-Type V6S which has a Torsen, apparently fits in the same housing as the other Gen3 diffs, supplier & details of the LSD center is TBC…
Theoretically the Torsen from the V6S could be fitted into other Gen3 non E-Diff housings
Gen3 E-Diff
Similar to the Gen3 but with the E-Diff option
X351 XJ, from V00001 to V58602 (3.0L S/C and 5.0L S/C only)
X150 XKR, from B32753 (5.0L S/C only)
X250 XF, from R47154 to S61361 (3.0L S/C and 5.0L S/C only)
2.56:1 (XF and XJ 5.0L S/C with 8-speed auto)
3.31:1 (XF, XK & XJ 5.0L S/C with 6-speed auto)
E-Diff is electronically operated LSD.
Note that the XJ from V58603 and XF from S61362 has a new version E-Diff with 2.56:1 ratio in conjunction with the 8-speed transmission but does not appear to be Gen4 as per the F-Type
Gen4 E-Diff
Similar to the Gen3 E-Diff but with different mounting of the E-motor, probably other changes
X152 F-Type, from (5.0L S/C & V6S AWD)
2.56:1 (F-Type V8S, R, RWD & AWD)
3.31:1 (F-Type V6S AWD)
E-Diff is electronically operated LSD.
Some nice cutaway pictures of the F-Type E-Diff here

Summary
All N/A cars have open diffs
All 4.2L S/C cars have open diffs
All 5.0L S/C cars have E-Diffs
The 3.0L S/C XF & XJ have E-Diffs
The 3.0L base model F-Type has an open diff

Hey Cambo
I Have a 2009 jaguar xf sc. My diff is completely shelled, I know shocker. There is an x200 on ebay for sale with the same model number and 3:07 gear as my XF. 6w93-4A213-BB. Mine looks the same. Are these interchangeable?

Sorry, my bad. My question was unrelated to the original question.
