1996 Jaguar XJ6 Vanden Plas. There has been whining noise coming from the rear. No vibration, shimmy or grinding noise at all. Had the differential fluid changed. No metal found in the REALLY OLD fluid. There is no evidence of any leakage anywhere, All joints are tight as can be. Mechanic hooked up microphones to several moving points of the rear and then I took him for a ride. Well Drivers side output bearing is SCREAMING. My question is, Is there a way to easily change this bearing with out dropping the subframe? The car is so clean and nothing looks rusty at all as it was a snow birds car prior to our purchase.

 

There probably is a way, but the subframe removal is really a piece of cake compared to the rest of what has to be done, in my experience.

 

There is no need (indeed no advantage) to removing the subframe or the diff to replace the output bearing.

1. Remove the inner driveshaft nuts (bottom arrow) and move away the driveshaft.
2. Remove the bolts holding the output shaft and bearing flange (upper arrow) and pull out the assembly.
3. Take the assembly to a bench and remove the bearing collar. This is an interference fit on the shaft and needs to be split to remove. The recommended method is to drill increasing size holes in it until it can be split with a chisel.
4. When the collar is removed the bearing can then be removed and replaced, and a new collar driven in to place.
5. Also replace the oil seal in the output flange before the bearing/collar are put in place.
6. Refit the assembly and the driveshaft.

 

Great report, Brendan!

The only thing I would add is to be a little careful with the mounting flange if you drive the new collar on with a hammer and pipe. The flange is thin around the five screw holes and could be damaged if you subject it to any undue pressure at those points. I have a small hydraulic press that makes the job easy.

I have some additional photos of the job on our '93 XJ40, which is essentially identical to the X300:

Yes good point Don, and your pictures / write up on Jag Lovers are excellent - I haven't seen that one before.

 

Don and Brendan both of you are reliable individual as you do not pretend to know but seriously have the knowledge and experience to share, TWO THUMBS UP TO BOTH OF YOU.

 

The microphone idea sounds interesting, how do you do it?

It's always great to give thanks of praise. I personally want to thank you all. I hope I can provide helpful. I love this family.

 

My mechanic has a tool which consists of 4+ radio transmitters which can be placed in specific areas of the car. This helps with pin pointing noise from suspensions, rear differentials, engine, any place where it is difficult to pin point the noise points. Then the car is taken out on the road and the tool can have each channel switched. The key is to write down which radio transmitter number is attached to what so when you dial a specific radio to transmit you can pin point what is making the noise. You also have to make sure you secure the transmitters properly no to fall off or get twisted in moving parts.
