Default Creaking while jacking up C4

Hey guys,

While doing an inspection of the fluids in the car, I noticed the brake fluid was a dark brown color, and I figured I'd do a brake bleed. I am new to DIY auto repair, and am excited to give this a shot (with some help).

I've read a fair amount on how people jack up their C4s, and I figured I'd try the factory recommended locations first - meaning under the rocker panels as indicated next to each door. When I did this, there was a lot of creaking. I know it is an old car (1991), but I have also read that these C4s can flex, and it got me a little worried. Should I be worried?

I have a low-profile jack from HFT that can fit under the front lip, but it isn't long enough to reach the front cross member. Should I just buy ramps and then use the jack?

As for raising the rear, I was going to purchase the Corvette GadgetMan's attachment. I've also come across a 4Guru Tech Tip guide that tells me where I can place jack stands once I lift it up.

I was wondering if you guys had any tips ...

All of mine have squeaks of various sorts if not jacking up square
If you use a floor jack under a rear jack point you can lift the whole of that side off the ground so there is obviously not too much sag

I jack my 1992 up from the front of the two side jacking points. Both the front and rear tires come off the ground. If I want the rear a little higher I put a jackstand under the front frame and then jack the rear up.

Thanks for the help guys. I got a heavy duty Craftsman hydraulic jack and did as Kmcoldcars suggested.
It worked great.
