In this generation of the XJ there were several changes. Double sided keys, optional illuminated entry sysem,
carpeting for base models, leather interior just like the Limited, stainless steel exhaust system was fitted to all models and driver side airbags.
Both the four- and six-cylinder engines were improved to bring smoother peformance, being more responsive, better towing capibility and reliability.
The electrical system was upgraded via a heavy-duty alternator and battery. And the engine received a stronger engine block, aluminum pistons and powertrain control module.

Driveshafts
Front driveshaft from 1987 onward is a " double cardan" two piece driveshaft with a CV joint at the transfer case end.
Rear Driveshaft
The rear is a one-piece shaft with standard u-joints at both ends. The slip yoke is located on the output shaft of the transfer case.
On 1984 - 1995 XJ's the yoke slides in and out of the transfer case and is lubricated by transmission fluid internally.

Rear Axles

Sometimes Dana 35 axles are referred to as Dana 35C - The "C" doesn't mean c-clip. It stands for "custom" meaning it came from Dana unfinished.
Note on 8.25 axles - none of these axles were used on XJs with ABS brakes. If you have ABS, you have the Dana 35. Without ABS you could have either axle.
