I drive a 1980 Jeep CJ-7, and I've noticed when I turn the wheel sharply to the left or right, I can hear a hissing sound. It seems to be coming from the engine compartment/end of the steering column area. Is this a potential problem, or nothing to worry about?

Probably something steering related... does it have power steering? When did this start? Side note: your Jeep is 33 years old, if the only thing wrong with it is a hissing sound, you deserve a pat on the back. – hillsons Mar 14 '13 at 1:50

When the steering wheel is at the end of its travel (completely left/right) it is normal that the power steering pump starts making some extra noise

At max travel, the steering pump will produce its maximum pressure and will have to work the hardest. This will create a "hissing" type noise.

When the fluid level is low, then you will hear the pump moaning the whole travel range. You could easily check the fluid level yourself, there is a small dipstick fixed on the bottom side of the fluid fill cap. (the cap itself has a yellow decal with a steering wheel on it)

The pump itself is just at the right side of the alternator when standing in front of the engine (It's been a while since I've seen one of those in the shop, so the location may be different).

As cinelli stated this is definitely something related to the power steering pump. Check your power steering fluid level and maybe replace it.

If that doesn't help you may need a new power steering pump.
