Sorry for the lack otftext to go along with this post,I will try to be a little more wordy in future!
Cin was driving,came to a light,went to go,and she said the car "lurched",and made a clunking sound.A slight grinding sound followed as she nursed the car home.
On a test drive,the back of the car felt loose,and a slight "grinch;grinch",matching my road speed.I placed a rafter square against the wheel,and the top of the wheel was a full two inches in toward the car.Very visible.
It came apart quite easily,Haynes book not much help,seems I have to be a dealer to take it apart;HA!
Timken bearings throughout,new Timken,s ordered to go back in.
The last pic shows the only way to remove the small races from the carrier,No way to get a drift on the back of the race!
I am no stranger to bearing carriers,but this is the first Jaguar assembly I have ever had apart.
Seems to me,that this failure was caused by lack of lubrication,after all,we service our front wheels all the time,not so bad!
Cindy,s beloved buggy now has 237000 kms,and these do not look like they have seen any service,EVER!!!......NOT EASY TO DO!!!
If the bearings had seen a shot of grease every 5000kms,we would not be in this kind of shape.
I will be looking at the possibility of installing grease zerks,I do not want to wonder why Jag did not do it in the first place.As we continue along with this job,I will post more pictures,and try not to mess it up!haha
Looking at the assbly. from a design point of view,LOTS of load,NOT much R.P.M.
Anyone have the spec for preload?seems that "shim to zero play and one or two thou less" would be of the order here.

Hi Jim,
You shouldn't have to mess with the shims - just replace the original ones in the same places where you found them. The Timken bearings are manufactured with such precise tolerances that you should be just fine. The main thing is to use a new axle nut as specified by Jaguar because the helical insert deforms when the nut is torqued and is not reusable, and torque the nut to spec (230 ft. lbs.?), which pulls the bearings tight to sandwich them firmly against the assembly. You'll need a 250 ft. lb. torque wrench.
I have a lot of photos of this job in my albums, but the large images may still be down at Jag-Lovers - sorry if that's still the case.
OK,after a little thinky,and many beers,here is what I did,seems that the only place to get a grease gun onto a fitting, is at the top of the carrier,beside the ABS sensor.
So,I pulled the sensor out,allowing a 1/8'' drill at around a forty degree angle to pass clean into the cavity.
Then drill at a ninety degree angle on top of the hole to cut a shallow thread,M6x1,and use a 90' grease fitting.
Now a shot of grease every oil change will keep things fresh!
Cheers,Jim and Cindy Drill going in Drill inside the grease cavity
With everything installed,wheels and all,you can still get a grease gun loaded with your favorite flavor,onto the fitting!
