2700x1923 230kb(If the image has failed to load, click on it to view large version) Description: Before you raise the car and support it on jack stands, put the transmission in Park, set the handbrake, and loosen the rear axle nuts with a long breaker bar. The single-use deformed-thread Nylstop nuts are torqued to 221-236 lb-ft, so you need all the resistance available to break them loose.
2400x1949 236kb(If the image has failed to load, click on it to view large version) Description: Don’t even bother trying to disconnect the handbrake cables from the rear wheel hubs. It’s frustrating and unnecessary. Instead, fully disengage the handbrake lever, then, working under the car, remove the cotter pin and clevis pin from the wishbone below the driveshaft…
1900x1456 229kb(If the image has failed to load, click on it to view large version) Description: Then disconnect this slip union in the cable that runs from wheel to wheel. On our ’93 this union was to the left of the driveshaft when facing the rear of the car. You may need to clean gunk and grit from the union before the cable can be pressed toward the center of the joint and slipped out.
2991x2592 227kb(If the image has failed to load, click on it to view large version) Description: Each half of the handbrake cable is secured to the front differential mounting frame by a slide-on circlip (arrow).
1800x799 230kb(If the image has failed to load, click on it to view large version) Description: You can do the bearings with the hubs still connected to the control arms by the lower pivot bolts but disconnected from the axles, but it’s easier if you remove the axles and do the work on the bench. See my archive posts and photo album on Differential Removal for details on removing the axles.
2054x3162 223kb(If the image has failed to load, click on it to view large version) Description: It’s convenient to hold the axle in a vise while removing the pivot bearings and hub. Pad the axle with a piece of thick leather or softwood.
2000x1579 229kb(If the image has failed to load, click on it to view large version) Description: Begin disassembly by removing the hub carrier pivot bearings, seals and pivot bolt sleeves. Don’t lose the thick spacer washers on each end of the pivot bolt sleeve, which may fall out as you separate the hubs from the control arms.
2200x3191 210kb(If the image has failed to load, click on it to view large version) Description: If the hub won’t pull off the axle by hand, use a 3-jaw puller.
2200x2811 214kb(If the image has failed to load, click on it to view large version) Description: From inside the carrier, use a hammer and socket with a diameter a little smaller than the hub tube to tap the hub downward until it is free of the ABS reluctor ring, or use a hydraulic press to push the hub out.
2000x3251 215kb(If the image has failed to load, click on it to view large version) Description: The U-joint and splined shaft with the hub and carrier removed.
2142x2423 231kb(If the image has failed to load, click on it to view large version) Description: Hub damage is rare, but clean them thoroughly and inspect carefully for cracks or other problems. If any wheel studs have damaged threads, now is the time to replace them. As of this writing, they’re still available new from Jaguar (all XJ40s and X300s used the same studs).
2200x2123 228kb(If the image has failed to load, click on it to view large version) Description: Set the carrier on the bench with the hub end down and begin disassembly on the inside of the carrier. First out is the ABS Reluctor Ring, or “Sensor Rotor” in Jaguar-speak.
