The point of taking spares is to carry the items that will enable you to keep driving ie. what will stop your vehicle from moving if it breaks due to a mechanical or physical problem eg. bearings, springs, flat tyre.
The list of spare parts you choose to take on a trip will depend on your assessment of risk vs packing space. Start by checking your vehicle service manual (sometimes difficult to obtain if you've purchased second-hand but worth the expense) and look at every spare item listed.
Even if you don't know how to perform the repair, at least if you have the parts with you someone who stops to help you might. Many townships cannot hope to keep stock every spare part for each vehicle type. To order and wait for parts to arrive in remote parts of the country are not only expensive and slow, but a waste of precious travelling time. It could really ruin your trip if you can't move on.
An ideal list would be:
- Set of springs to suit your vehicle
- Trailer spares if towing- springs, spring hangers, axle
- Water pump and fuel pump kits
- Ignition coil, plugs, condenser, points, rotor button, distributor cap
- Radiator and heater hoses and clips
- Spare belts for fan/aircon/alternator/power-steering etc
- Flexible tubing and spare hose clamps
- 4mm and 6mm electrical cable
- Electrical connectors
- High-tension leads
- Fuel filters, oil filters, air filter
- Lubricants, fluids, oils
- Wheel bearing kit and packing grease
- 2 spare tyres (at least one spare wheel)
- Puncture repair kit and recovery tools
- At least 2 inner tubes (a tubeless tyre with a hole can hold air if you insert a tube)
- Related tools from the list above
And it is also wise to carry spares of the following important items:
- Aerials for UHF, HF
- Globes for headlights, taillights, blinkers etc
- Spare car keys[/LH]
- Shock absorbers - optional. They don't stop the car and are readily available but driving without one shock is not only uncomfortable it can put such undue force on the other shocks that they are all likely to fail. Also fitting a mismatching length shock absorber on one side of the vehicle will do no good. May as well carry one or two if you have the space.
