- Axles: The Dana 30 front axle and Dana 44 rear axle were standard. Key parts include: axle shafts, bearings, seals, differential gears, and brake components.
Important Considerations:
- Engine Choice: When replacing engine components, ensure compatibility with your specific engine. Identifying the engine code (stamped on the engine block) is crucial.
- Transmission Type: Verify the transmission type before ordering parts. Differences in gear ratios and internal components exist.
- Gear Ratios: Maintaining the correct gear ratios in the axles is vital for optimal performance. Changing tire sizes can necessitate a change in gear ratio for proper power delivery.
2. Suspension and Steering:
- Leaf Springs: The CJ-5 uses leaf springs for both front and rear suspension. Parts to consider include: leaf springs (main leaf, individual leaves), shackles, bushings, and U-bolts.

Important Considerations:
- Spring Rate: Selecting the correct spring rate is essential for ride quality and load-carrying capacity.

Important Considerations:
- Brake System Condition: Inspect the entire brake system thoroughly for leaks, corrosion, and worn components.
- Brake Fluid: Use the correct type of brake fluid and bleed the system properly after replacing any brake components.
