Jaguar Rear hydraulic Hub puller for Mk1 & 2 solid or disc (US term as they all have brake discs) wheels fitted to live axles, not as shown in photo which was 10 or more years ago.

Does the job / is the equivalent of Churchill JD 1 which is shown in the picture,  this in one of only hub pullers that can remove the rear Jaguar 5 stud hubs, approx 12 ton capacity

They also fit independent axle hubs as sometimes they can be difficult to remove, Jaguar from E Type to XK8 or later

These pullers come with a special cap that stops damage to the end of the halfshaft, full instructions & safety advice

A Workshop tool, not terribly expensive for what it is.
