The first digit (from the left) of the odometer didn't turning over. I had 89,999 miles, but rather than going to 90,000 miles, it reads 80,000 miles.

And my speedometer cable makes noise.

I took out the three layers of panels that protect the gauges. But, how do I take out the entire display cluster? I need to get behind it to disconnect the speedometer and replace the odometer.

Do I need to romove the dash pad above and the kick panel below?

You will need to follow the speedometer cable into the back of the speedometer. There is a tab that you need to push that is on the back of the speedometer but while you are pressing the tab you need to pull on the speedometer cable at the same time. Then there are two 10mm nuts in the corners of the gauge cluster in the front that needs taken out. I found that it is also easier to drop the steering column. There are two 13mm or 15mm (I can't remeber which right now) nuts that hold the column up. After all that is done the cluster should pull right out.

 

I took out the gauge's frames and I couldn't anymore nuts to take out. Are these two nuts on the back of the gauge cluster?

When I looked inside the gauge cluster, all I saw were the display panel's light bulbs. Do I need to remove these bulbs too?

Hm; you've got a "1989 2.8 5-speed", but is it a Camaro or Firebird?

For the camaro, look in the lower left and lower right corners of the dash cluster. There are holes with bulbs in them. Two holes (one on each side) don't have bulbs, they have "fake" nuts. They're stamped out of a gray steel, and "bite" onto a plastic stud. You need to remove these to pull the console out.

To lube the speedo cable, buy some speedo lube. With the cluster out, remove the center cable from the outer sheath by pulling with a twisting motion. When the whole metal cable is out, put a glob of the lube into the palm of your hand. Feed the cable back into the sheath with one hand, while you run the cable thru the glob of lube in your other hand. Again, use a twisting motion as you reinsert the cable. DO NOT LUBE the last inch of the speedo cable, where it goes into the gauge. (It can cause the lube to get inside the speedo and totally screw the speedometer up.)

Before you pull the cable out, take note (and maybe a measurement!) of how "Deep" the end of the cable is, compared to the cable sheath. This way you'll know when the cable is fully seated.
