The spring broke on my Carefree Omega I slide topper. I bought a replacement spring and did the job today. Thought I would pass on my experience in hopes of helping someone else.
On the Omega I, the spring is in the right end, as you're standing in front looking at the slide. Below are the steps I took.
1. Drilled out the two rivets holding the end cap on the tube on the right end.
2. Pulled the arm and end cap out of the tube, along with that end of the broken spring.
Now comes the problem! The other end of the spring is up in the tube, and I couldn't figure out any way to reach in and get it! I tried a piece of 1/2" EMT conduit with a stiff wire in the end with a hook, but no luck!
3. Drilled out the rivets on the left end of the tube and slid the tube off the arm, laying the tube back on top of the slideout.
4. Used a length of 3/4" PVC pipe to stick into the left end of the tube, pushing the broken spring out the right end!
5. Reattached the tube to the arm assembly on the left, putting in new 3/16" aluminum rivets.
6. Held the new spring vertically and sprayed it heavily with the new WD40 Waterproof Silicone Spray, hopefully to prevent it from rusting like the old one was.
7. Inserted the new spring into the tube and slid the end cap on the end.
8. Hooked the end of the arm into the end of the spring and very carefully pushed the end cap on and put in new rivets. There is nothing that locks the arm onto the end of the spring, so you have to rotate the arm about one turn to keep it locked while you slide it into place.
9. Rotated the arm 17 turns counter-clockwise, slid it into position and put the retaining bolt back in the mounting bracket! I had trouble getting the arm in the right position because of the spring pressure, and had to roll the tube about 1/2 turn to release some pressure, and use a drill bit in one of the holes in the cap and the anti-furling lock to relieve the pressure.
Mission accomplished! Hope this spring lasts another 14 years like the last one!
