Using Tools
If you're new to all this car-fixing stuff, you might find these guides to using the more awkward tools useful:
Torque wrench - very useful when you don't want to tighten a nut too much.
Adjustable spanner (wrench) - don't have a spanner that fits? What you need is one that changes size.
Thickness (feeler) gauge - helps set the gaps you need between various components.
Grease gun - for injecting grease in to axles and other places.
