where do i lube?
 

I was changing oil in a pair of Proteges today ('93 DX and a 2002 P5),
and I realized that it was probably time to "lube the chasis" as they say.

So while I was under there, I looked for place to squirt some grease,
and I only found one place on each car that looked like it wanted to
have grease pumped into it. It was a rubber boot toward the center
of the car on a rod that ran front to rear.

Can anybody describe where I should be lubing Proteges? I guess
there are three possibilities:

There's only one place and I hit it. Yay!
There are no places to put grease, so I shot some where I oughtn't.
There's more than one.

Anybody know?
