After driving and enjoying the ride in my 54 with the Jag front end, I have developed a leak in the power steering rack.
Anyone have experience rebuilding a Jag rack? Or is it more feasible to buy a replacement and use the current one as a core.
The power steering fluid is dripping from the drivers side boot.
Feedback welcome.

They can be rebuilt but it’s a tedious process you need a dial gauge and have to set them up just right or you end up with stiff steering or if it’s not centered correctly will blow the seals out again on your first full lock turn
Better off getting yours rebuilt
Install the trw bushings at the same time Makes a big difference on steering feel

These should only be rebuilt by a shop that has had experience rebuilding them before.

Hi Ben, I think you have the right plan, but make sure they know what they are doing and understand Jag racks. If they do it right it will do another thirty or forty years. If they don't you have warranty.
Hey VDP, do you mean use aftermarket nolathane bushings in the mounts? They will probably make it a touch more responsive. But they will also transfer more road noise and vibration. So if it's a cruiser then I would go stock rubber, if you want it sharper then that will do a little, but you may get more noise and discomfort.
If you want super sharp and responsive steering then you really don't use a power rack in the first place. But if you want one of the best touring front ends available then you already have it. V12 jags will sit at 120mph plus all day and they don't fall over in corners either.
What most folks call mounts, Jaguar calls isolators. Same as the one in the column. If you were driving a Kit Cobra with a Jag front and you did track days occasionally then fine to use nolathane mounts.

Ben, you might call the nearest Jag parts dept and make friends with the parts man and ask him where they send their power racks to be rebuilt. That's what I did.

If it is coming out of the boot, it is a piston seal leaking. I would try some Lucas power steering stop leak first i have been suprized what a little lucas can do. That seal is a round seal about 3/32 of an inch square. If the boot is torn pull it off and make sure the piston shaft is clean. The drivers side end will have the teeth that the pinion runs on and the seal is past that area. They can be rebuilt it is not very complicated but does take a special tool to install one seal and some knowledge of hydraulics.
Autozone does have a premium rack that comes from a Jaguar rebuilder that is very good, you can check there site for availability and i have seen a 20% coupon number on there from time to time.

Hey kiwi not sure of the compound but the bushings are made by trw they are blue when I worked at jag we installed them all the time made the steering more responsive but did not really effect noise or harshness to the point a jag driver complained
The trw bushings pressed into the rack same as oem style there are 3 required

I used the urethane bushings on SWMBO's 76 XJ-12 also. They worked great.

In doing research to find a replacement, it appears as though there are two different units. One has inner tie rod threads that are 14 millimeters long, while the other the threads are 16mm long.
I can't imagine that there would the that much difference in the racks, but the 16mm variety is about double the price.
I have no idea what the inner tie rod thread length is on the rack that is currently installed.
Any way to tell a difference without taking it apart? Or are the 14mm and 16mm racks interchangeable? I can't imagine that 2mm (0.0787 inches) would make that much difference.

I might be wrong but, I thought the 14 mm they were referencing would be thread diameter not length.

Hi VDP, that's what I was wondering. Whether we were discussing internal bushings or mounts.
I used Nolathane bushings inside my Capri rack, but it's not power steer so no internal pressure.

I may be confused about the length versus diameter.
My main question is if I get a replacement rack, does it make any difference if the measurements are different?
If I go this route, I plan to send my old one back for a core.

Those 14mm and 16mm measurements are the thread diameter of inner of the tie rod. Most of the racks i have seen are all 16mm thread dia.A rack with either size thread will fit the same application.
