To remove a stuck aluminum tube from a steel tube, you can try using a penetrating oil to help loosen the bond between the two metals. Apply the oil to the area where the tubes are stuck and let it sit for a few hours or overnight. Then, try using a rubber mallet to gently tap the aluminum tube to see if it will start to loosen. If that doesn't work, you can also try using heat to expand the aluminum tube, making it easier to remove. Use a heat gun or torch to heat the aluminum tube, being careful not to overheat it or damage the steel tube. Once heated, try twisting and pulling the aluminum tube to see if it will come loose. If these methods don't work, you may need to seek professional help to safely remove the stuck tubes. **
