All XJs were built as a "Unibody" design with the body and frame rails tied together as one piece as opposed to a body on frame design. All XJs have solid axles front and rear. The suspension is coils/leaf springs. All XJs came with disc/drums brakes.
(small differences may occur depending on optional equipment or trim level)
wheelbase = 101.4"

curb weight 2wd = 2,891 lbs - 2,993 lbs
curb weight 4wd = 3,057 lbs - 3,386 lbs
cargo capacity = 71.0 cu ft.
The body comes in both 2-door and 4-door styles with a rear hatch (liftgate).
side-impact beams were added in the doors and roof was strengthened. The 3rd brakelight was added to the top of the liftgate.
the body structure was strengthened some although it was not noticeable in appearance.
the body (and interior) was redesigned to freshen it up a bit. Most noticeably it gave the body smoother lines by changing the bumpers, flares, and moldings. The front fender was trimmed just below the headlights and replaced with plastic bumper endcaps that wrap around to the wheel well. The liftgate was also changed from fiberglass to sheet metal in this year. The windshield washer bottle was also moved to the inside of the drivers side front fender.

The transfer cases used are all chain driven with aluminum housings. NP stands for "New Process" which is the brand, if you will. The newer ones are NV instead which stands for "New Venture". It is the same transfer case just a different name.
NP207 - "Command-Trac" part-time only - 2.61:1 ratio low range - used 84-87
NP231 - "Command-Trac" part-time only - 2.72:1 ratio low range - shift pattern 2H - 4H - N - 4L - used 87-01

Front Driveshaft - On 84-87
XJs (NP207 t-case) the front shaft is a "GKN" style shaft. On 87-01
XJs (NP231/242 t-case) the front 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 84-95
models, the yoke slides in and out of the transfer case and is lubricated by the ATF fluid internally. On 96-01
due to a design change, the slip yoke is external (does not slide in and out of the transfer case). This slip yoke is covered with a rubber boot.
Dana 30 high pinion - reverse cut - 27 spline, 1.16" diameter shafts, 7.13" ring gear - used 84-99
(some axles through 91
are vacuum disconnect, 92+
are non-disconnect, 89-95
with ABS have 5-297x u-joints, all 95+

(Note on Dana 35 axles sometimes referred to as Dana 35C - The "C" does not stand for 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. 8.25 axles are c-clip)
