Hello folks,
I have a 64 MKII. I want to install new front stub axles and therefore need to remove the originals. How does one remove the stub axles. I assume that they are a press fit and that one should use a press to push the back side so that the axle will push out of the carrier. Also assume the reverse for installation. I also know what happens when you assume things, so I thought I better ask. Nothing in the shop manual about this that I saw.

Hope someone who has actually done this can be of some assistance.

Thanks very much.

Hi Lin

Yes, I have replaced a stub axle, and assuming the Mark 2 is the same as the XJ6, which I am sure it is, No, it is not a press fit, it is on a taper just like the balljoints except much bigger.

I removed the old one by first removing the hub carrier, (the upright), taking off the very large securing nut on the stub axle, then mounting it between two large baulks of timber with the stub axle facing downwards, but clear of the floor, then walloping it with a sledge hammer - out it came !! Clearly as it is scrap, you are not worried about damaging it. You then insert new stub axle and tighten up the nut to the specified torque. I think if I remember correctly, the nut is a self-locking type so you may need to buy another one. Then reassemble suspension as normal.

I actually found the job quite easy.

 

Thanks. That is what I meant by press fit. Rather than "hammer" it out, I was going to put it in a press and exert pressure from a press to pop it out. Thanks very much!

Last week I had enquired about the process for removing the stub axle from the carrier. I have a friend who owns a number of Kenworth dealerships, so I took the parts to one of his shops to use his press. I didn't actually do the job, but the fellow who did said that it took twenty tons of pressure to "pop" the first one, and about thirty to break the second one loose. Wow, that is tight! One of those "don't try this at home moments!"

I didn't press the new stub axles in hard, just put in place and will tighten down when I assemble the front end?

Just thought I would offer an update.

Lin,

Did you take a picture of the parts?

What Fraser described is a taper fit which requires some initial force to break the fit but will then fall apart. A press fit describes two parallel parts with sufficient interference that they will require to be pressed together, tighter than a push fit and looser than a shrink fit.

The main thing is that you got the job done, congrats!

 

The latest Jaguar Enthusiast Club magazine has a feature on maintenance of the Mk 2, S-Type, and 420 front suspension, and includes the official Jaguar technical drawing of the suspension layout. This confirms the stub axle is secured on a taper fitting.

 

I didn't doubt you Fraser, I think the confusion was over the definition of a press fit, or maybe it was only me that was confused.

 

There is no question that it is a taper fit. A quick look at either the manual drawings or inspection of a new stub axle confirms that. My question was about its removal. What I was asking in simple terms was " to remove do you strike the back side of the stubaxle with a sharp blow (big hammer) or do you push it out with a press? " The word "press" is getting confused. I was referring to the procedure and a tool - not the design and fitment of the component.

A sharp blow from a hammer may well have worked -I didn't try it. Using a press with considerable force did work. As was stated, the important thing is that they are out and replaced, and I am moving on to other work! Now, to get those bushings in-let's see, push, pull, press? Just kidding!

Thanks again.
