## Rear Shocks

Whereas the front suspension has a strut unit consisting of the shock running inside the spring, the rear suspension contains the spring separate from the shock. Replacing the rear shock is relatively easy. It is held with two bolts at the top attached to the frame body, and one bolt and bushing at the bottom attached to the wheel unit.

The lower bolt goes through a bushing on the shock and screws into a welded nut. Since this is fully exposed to the elements, everything was heavily corroded, and it was hard to even notice that the nut was actually a welded nut. The bolt just wouldn’t budge, even with an air impact wrench.

I had to pull out my oxyacetelyne torch and heat the nut until it was cherry red. The rubber inside the bushing was also starting to burn. Using an impact wrench while the whole thing was still hot did the trick in removing the bolt.

In comparison, the upper two bolts were a lot easier to remove. However, the threads are not very deep, and it is easy to strip the threads.

## Alternator

Replacing the alternator on the Kia Rio is probably one of the most difficult work I have done, which is a strange thing to say because I have done far more complex tasks on this vehicle. Even though it is relatively easy to disconnect the belts and remove all the retaining bolts, there is simply no room to extricate the alternator out of the engine.

At the top, the path is blocked by the AC lines and the power steering lines. At the bottom, the the mounting block obstructs the path.

After checking many sources of information, the only apparent way to get it out was by lifting and moving the engine. This clearly seems like a poor design and unnecessarily complicated.

Therefore, passenger-side engine mount was removed, letting the engine hang from the other mount points. Then a hydraulic jack was placed under the oil pan to lift the engine block. This procedure moved the engine by about an inch, and allowed the alternator to just barely squeeze out of the bottom of the vehicle with no extra room to spare.
