To lower the spare:
1. Locate the Release Latch: This is usually a small, often easily overlooked latch or lever located near the tailgate or on the carrier itself. It might require a bit of fiddling to find. Look carefully around the spare tire's mounting area.
2. Release the Latch: Once you find it, carefully push or pull the latch to release the retaining mechanism.
3. Lower the Spare Tire: The spare should then swing down under its own weight. You may need to help guide it slightly as it descends to prevent it from hitting anything.
To raise the spare:
1. Lift the Spare: Carefully lift the spare tire. It's likely quite heavy.
2. Guide it into Position: Manually guide the spare tire back up into its mounting bracket on the carrier. You might need to align it carefully.
3. Secure the Latch: Once it's in place, make sure the latch engages firmly to secure the spare.
Important Considerations:
* Rust and Corrosion: On a vehicle this age, rust and corrosion can significantly affect the functionality of the latch and hinges. Lubricating the hinges and latch mechanism with penetrating oil might help.
* Weight: Spare tires are heavy. Be careful not to injure yourself while lifting and lowering the spare. Consider getting help if needed.
* Condition of the Carrier: Inspect the carrier for any damage or weakness before using it. A damaged carrier could fail, resulting in the spare tire falling off.
If you can't locate the latch or if the mechanism is seized, you may need to consult a repair manual specific to your 1985 Nissan PU 2WD or seek assistance from a mechanic. A picture of your specific carrier would be helpful if you are having difficulty locating the release mechanism.
