JEEP TECH

Jeep Cherokee (XJ) Stock Specifications


All XJs were built as a "Unibody"…meaning that the body and frame rails not just tied together, they are one piece, as opposed to a frame with the body mounted to it (like Wranglers are). All XJ's have solid axles in the front and in the rear. The suspension consists of coil springs up front and leaf springs in the rear. All XJ's came with disc brakes in the front and drums in the rear.
Dimensions
(There may be small differences, dependent upon trim level and/or optional equipment)

Wheelbase = 101.4"
Overall length = 165.3" - 168.8"
Overall width = 67.9" - 70.5"
Track = 58"
Height = 64" (with roof rack 66.8")
Ground clearance from differentials = 7.3" (Upcountry = 8.3")
Approach angle = 37.6º - 38º
Departure angle = 31º - 32.1º
Breakover angle = 21º - 21.9º
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 to the doors and roof was strengthened. The 3rd brakelight was added to the top of the liftgate as well.

In 96 the body structure was strengthened some...it was not noticeable in overall appearance.
In 97 the body and interior were redesigned. 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 windshield washer bottle was relocated to the inside of the drivers side front fender and the liftgate was also changed from fiberglass to sheet metal.

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
BA10/5 - 5 speed manual - manufactured by Peugot - used only up to 89
AX5 - 5 speed manual - manufactured by Aisin - used with 2.8L V6 and 87+ with 2.5L I4
AX15 - 5 speed manual - manufactured by Aisin - used with 4.0L I6 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
All the transfer cases used are all chain driven with aluminum housings. T-cases were designated either NP or NV. They are essentially the same t-case...just a different "brand name" (NP was used for the purposes of this list:

NP ="New Process"
NV = "New Venture"

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
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.
Note: 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: 8.25 axles - none of these axles were used on XJ's 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.

Gearing
3.07 - used with 4.0L engine / manual transmission
3.31 - only available on older (pre87?) 2 door XJs with "Fuel Economy" package
3.55 - used with 4.0L engine / automatic transmission
3.73 - found in some XJs with the towing package
4.10 - used with 2.5L engine usually, and older XJs with the "Off-Highway Vehicle" package.
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.
Airbags
Drivers side airbag (mechanical) was added in 1995.
Passenger side airbag was added in 1997. Airbags changed from mechanical to electronic in this year also.

51 Oxygen sensor stuck at lean position (this may be tripped by a bad MAP sensor system causing a rich condition.

If you get poor cold driveability, stumbling and bucking, and acceptable warm driving with poor gas mileage (a drop of 10 mpg or more), that is usually the O2 sensor.

Axle Trouble Shooting Guide
CONDITION POSSIBLE CAUSES
Noise in all driving modes Road and tires, wheel bearings

Noise tone lowers with vehicle speed Tires
Noise louder on turns Differential pinion and side gears, axle wheel bearings
Noise in one or more driving modes Ring and pinion gears
Clunk on change of speed or direction of power flow Worn differential shaft or thrust washers; worn U-joints
Wheel noise Wheel loose, faulty or bad wheel bearing
Vibration Damaged drive shaft, missing drive shaft balance weight, worn or out-of-balance tires, loose wheel lug nuts, worn U-joints, loose spring U-bolts, loose/broken spring, damaged axle shaft bearings, loose pinion gear nut, excessive pinion yoke run-out, bent axle shaft
Differential gears scored Insufficient lubrication, improper grade of lubricant, lubricant contamination, excessive spinning of tires
Loss of lubricant Lubricant level too high, worn axle shaft seals, cracked differential housing, worn drive pinion gear shaft seal, scored and worn yoke, axle cover not properly sealed, plugged vent or vent tube
Axle overheating Lubricant level too low, incorrect grade of lubricant, contaminated lubricant, bearing preload too high, excessive gear wear, insufficient ring gear backlash
Gear teeth broken Overloading, erratic clutch operation, wheel spinning, improper adjustment
Axle gear noise Insufficient lubricant, incorrect backlash, improper tooth contact, worn/damaged gears
Axle noise Insufficient lubricant, improper ring gear and drive pinion gear adjustment, unmatched ring gear and drive pinion gear, worn teeth on ring gear or drive pinion gear, loose drive pinion gear shaft bearings, loose differential bearings, misaligned ring and pinion gear, loose differential bearing cap screws, worn bearings
Limited slip differential The most common problem is a "chatter" noise when turning corners. The probable cause is incorrect or contaminated lubricant or lack of friction modifier additive in the lubricant, worn or damaged plates and discs, plates and discs improperly assembled
