Hola... esta es la informacion que tengo de las Cherokees o XJ :

Introduction

This page will detail the stock specs of the Jeep Cherokee (XJ) which was produced between 1984 - 2001 in the United States. That is a remarkable 18 year lifespan in which 2,884,172 Jeep Cherokees rolled off the assembly line! Originally designed and built by AMC, Chrysler continued the same design when they bought AMC in 1987. Anyways, the Cherokee was the icon of compact SUVs which led to a market full of those who tried to imitate it. Now the term "SUV" doesn't really mean a rugged vehicle that actually performs off the pavement, but the Cherokee remains one of the best "utility" 4x4s ever made.

Common Design

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 consists of coils for the front and leaf springs for the rear. All XJs came with disc brakes in the front and drums in the rear.

Dimensions

(small differences may occur depending on optional equipment or trim level)

wheelbase = 101.4"
overall length = 165.3" - 168.8"
overall width = 67.9" - 70.5"
track = 58"
height = 64"
height with roof rack = 66.8"
ground clearance (from differentials) = 7.3" - 8.3"
approach angle = 37.6* - 38*
departure angle = 31* - 32.1*
breakover angle = 21* - 21.9*
curb weight 2wd = 2,891 lbs - 2,993 lbs
curb weight 4wd = 3,057 lbs - 3,386 lbs
cargo capacity = 71.0 cu ft.

Body

The body comes in both 2-door and 4-door styles with a rear hatch (liftgate).

In 94 side-impact beams were added in the doors and roof was strengthened. The 3rd brakelight was added to the top of the liftgate.

In 96 the body structure was strengthened some although it was not noticeable in appearance.

In 97 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.

Transmissions

Manual Transmissions

AX4 - 4 speed manual - manufactured by Aisin - used 84-86 with 2.5L I4 and 2.8L V6 engines
T4 & T5 - 4 & 5 speed manual - manufactured by Borg Warner - used 84-86 with 2.5L I4 and 2.8L V6 engines

NV3550 - 5 speed manual - manufactured by New Venture - used in 00-01 in SE models with 4.0L I6 engines

Automatic Transmissions

Torqueflight 904 - 3 speed automatic - used 84-86 with 2.8L V6 and 2.5L I4 engines
30RH - 3 speed automatic - used with 2.5L I4 engine 94?-00
AW4 - 4 speed automatic, electronically controlled - manufactured by Aisin - used from 87-01 (87-91 models include a Power/Comfort button that adjusts the shift points)

Transfer Cases

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

NP228/NP229 - "Selec-Trac" - 4Hi(full-time) - N - 4Lo (part-time) - used 84-87
NP242 - "Selec-Trac" part-time OR full-time - 2.72:1 ratio low range - shift pattern 2wd - 4part-time - 4full-time - N - 4LO - used 87-01

Driveshafts

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.

Axles

Front Axles

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+ have 5-297x u-joints, all others have 5-260x u-joints)

Dana 30 low pinion - standard cut - 27 spline, 1.16" diameter shafts, 7.13" ring gear, 5-297x u-joints - used 00-01

Rear Axles

(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)

Dana 35 non c-clip - 27 spline, 1.18" diameter shafts, 7.58" ring gear, 2.62" axle tube - used 84-89
Dana 35 c-clip - 27 spline, 1.18" diameter shafts, 7.58" ring gear, 2.62" axle tube - used 90-01
Chrysler 8.25 - 27 spline, 1.17" diameter shafts, 8.25" ring gear, 3" axle tube - used 91-96
Chrysler 8.25 - 29 spline, 1.21" diameter shafts, 8.25" ring gear, 3" axle tube - used 97-01
Dana 44 non c-clip - 30 spline, 1.31" diameter shafts, 8.5" ring gear, 2.75" axle tube - used 87-89 on some(not all) XJs equipped with towing package.

Gearing

Cooling Systems

Open style - any normal cooling system used today. Opposite of closed style described below.

Closed style - has no radiator cap and utilizes a pressure bottle. This style cooling system was used in 87-90 XJs.
