Is it an Alfa Ideal? If it is, the front slide is separate from the rear slide. I had a 29' Ideal RL and the front slide was a hydraulic cylinder that pushed the slide in and out. The rear slide has a rack and pinion setup with a gearbox and shaft similar to the front jacks. If it is an Alfa and you have any questions, call Alfateers out of California, they bought all the parts inventories and prints from Alfa Leisure when they went out of business. They are very knowledgeable on these units, they will need the year model and serial number.
