Chrysler Cherokee XJ Technical Manual – What You Need on the Bench

If you have ever hung parts on a Chrysler Cherokee XJ using aftermarket data and ended up with a clunk in the front end or a leaky brake line, you know what I mean. This Technical Manual is the real OEM document – 626 pages of factory-sourced diagrams, torque values, and part numbers that Chrysler originally published for the 1998 XJ. No reprints, no photocopies, no third-party guesswork. You get the same book the dealer techs used. And let me tell you, that matters when you are pulling a front axle or bleeding the ABS unit.

Front Suspension & Drive – What the OEM Covers

Group 2 of this manual covers the complete front suspension and drive system. You get exploded views for the control arms (upper and lower – Fig. 2-110), front springs and shocks (Fig. 2-120), and the stabilizer bar with track bar (Fig. 2-130). Every fastener in those illustrations has a factory part number and a torque spec that belongs to the vehicle. I have seen guys torque the lower control arm bolts to 75 ft-lb from a generic chart and then wonder why the bushings squirm. The OEM spec for those bolts? You will find it in the manual, not in a forum post. The front axle section includes separate housing diagrams for 2WD and 4WD – Fig. 2-310 and 2-320 – so you don’t order the wrong carrier. Chrysler Stealth 1991 Technical Manual – Factory OEM Service is another Mopar manual with the same level of detail if you work on that platform.

Rear Axle: Chrysler 8.25 vs Dana 35 – Know Your Diff

Group 3 dives into the rear axle assemblies. The Cherokee XJ came with two different rear ends: the Chrysler Model 8.25 [DRA] and the Dana Model 35 [DRJ,DRM]. The manual gives you separate figures for each: Fig. 3-110 for the 8.25, Fig. 3-120 for the Dana 35. Each figure includes the axle shaft removal procedure, the vent location (Fig. 3-310), and the differential breakdown with and without Trac-Lok (Fig. 3-230, 3-240). If you are dealing with a Dana 35 that has Trac-Lok, the shim and preload specs are right there – not something you should guess at. The page numbers for those torque values are in the manual; I am not going to list them here because you need to look at the actual figure, not a paraphrase.

Service Brakes – Factory Procedure for ABS and Non-ABS

Brakes are where aftermarket manuals get dangerous. Group 5 in this manual covers front and rear brakes, the master cylinder and booster (Fig. 5-310), and the hydraulic control unit for ABS (Fig. 5-410). It separates brake line routing for LHD and RHD, with and without anti-lock brakes (Fig. 5-510, 5-520, 5-530). That is critical when you are replacing lines on a RHD Cherokee that was imported or a local LHD model. The manual also includes the specific bleeding sequence for the ABS HCU – you will not find that in a generic Chilton. Chrysler Stealth Technical Manual – 284-Page Factory OEM Specs follows the same format for brake systems if you need another reference.

Cooling System and Electrical – VIN Decoding Included

Group 7 covers the cooling system for all three engine options: 2.5L gas, 4.0L gas, and the 2.5L diesel (EN0). Radiator diagrams (Fig. 7-120, 7-130, 7-145) and charge air cooler (Fig. 7-147) are separate, so you get the correct part for your engine. Group 8 is the electrical section – starters, alternators, distributor, and all the sensors and relays. The manual includes a full VIN decoding table on page 1 and page 2, so you can identify exactly which Cherokee XJ you are working on by position 1 through 17. That is invaluable when ordering parts for a 1998 model with a 4.0L engine built in Toledo. Jeep Cherokee XJ 1999 VIN Decoding & Technical Data is a related manual if your year is 1999, but this 1998 manual covers 1997 through 1999 model years according to the VIN chart.

Audience Fit – Who Should Use This Manual?

If you are a home garage enthusiast who has swapped a few water pumps and wants to tackle a front axle rebuild or a rear differential refresh on your Cherokee XJ, this is the document you need. It assumes you have basic hand tools and a torque wrench, but it does not assume you have access to a dealer scan tool. The step-by-step procedures are clear, but they are not dumbed down – you still need to pay attention to the torque sequences. Beginners should start with the VIN decoding section to make sure they have the right engine and axle combination before ordering parts. Experienced mechanics will appreciate having the official part numbers on hand instead of relying on aftermarket catalogs that sometimes list the wrong brake pad shape for the 9-inch vs 10-inch rear brakes (Fig. 5-210 vs 5-220).

Source Authenticity – OEM vs Aftermarket Documentation

I have been in this trade for 28 years. Aftermarket manuals are fine for oil change intervals, but they do not carry the weight of a factory Chrysler document. This Technical Manual is an original OEM publication – the PDF you get is a scan of the actual Chrysler Corporation document, with all the figures, part numbers, and notes exactly as they appeared in the 1998 dealer binder. There is no third-party interpretation, no “typical” torque value. The suspension section alone (Group 2) shows you the exact control arm ball joint clamp load. The manual also references the Manual Transmission Manual Transmission in related drivetrain groups, though the main focus is on the axle and brake systems. For the AX-15 and NV3550, see the separate transmission manual Manual Transmission – this one stops at the clutch housing (Group 6).

Does this manual cover the 1999 Cherokee XJ?

Yes. The VIN decoding table on page 1 lists model year W for 1998, X for 1999, and V for 1997. The manual covers those three years with the same figures. However, the suspension and brake illustrations are based on the 1998 build, so minor changes in later 1999 production might not be reflected.

Are the torque specifications listed for every bolt in the front suspension?

Each figure (e.g., Fig. 2-110 for control arms) includes a fastener chart with torque values in ft-lb. The manual does not print a separate torque table, but the values are embedded in the illustration callouts. You need to read the figure notes. For example, the upper control arm pivot bolt torque is specified next to the numbered item in the exploded view. There are no generic “tighten to spec” phrases – it is all OEM data.

Enough talking. If you want to work on your Cherokee XJ without chasing ghosts or redoing jobs because of incorrect specs, get the factory paperwork. Access the Factory Manual from AutoRepairManuals and keep it on your tablet or print the pages you need for the job. Your torque wrench and your sanity will thank you.
