Frequently Asked Questions
Which CJ body styles and model variants does this manual include?
Coverage spans all CJ variants produced from 1949 through 1986, including the CJ-3A, CJ-3B, CJ-4, CJ-5, CJ-6, CJ-7, and the CJ-8 Scrambler pickup. Both early flatfender designs and the later high-hood models introduced with the CJ-5 are fully addressed with model-specific specifications and procedures.
Are the Dana axle and transfer case rebuild procedures included?
Yes. The manual provides complete teardown and reassembly instructions for the Dana 20 and Dana 300 transfer cases, as well as the Dana 30 front axle and Dana 44 rear axle commonly fitted to CJ models. Torque specs, bearing preload settings, and seal part references are all included.
Does the manual cover the AMC 258 inline-six carburetor and fuel system?
Absolutely. The 4.2L (258 cu in) AMC inline-six was the most popular CJ engine in the later production years, and its fuel system – including carburetor rebuild procedures for the Carter BBD and Motorcraft 2150 – is covered in full, along with fuel pump testing, intake manifold service, and emissions-related components.
What format is the manual?
The manual is delivered as a PDF file, compatible with any device running a standard PDF reader – including Windows PCs, Macs, tablets, and smartphones. The text is fully searchable so you can jump directly to any system, spec, or torque value, and individual pages can be printed for garage use.
