At this point it would really be great to have a sticky on the first post of this thread detailing what folks need to do, instead of reading through 17 pages of comments. Maybe a mod will throw this up front if it's accurate. If its not accurate, can somebody help me make it more accurate?
The steps as I understand it:
1. Block the back tires of the side you are NOT working on. Raise the side of the coach your ARE working on w/ your levelers so that the rear tire is grazing the pavement.
2. C-clamp the helper spring and the stock Ford spring. Clamp it just tight enough to hold it in place in case it snaps back at you.
3. Using a 7/8" ratchet wrench, begin tightening the 'top' nut a few turns. Starting from the front of the helper spring, work on each side a little at a time. Back the 'bottom' nut up to the top nut after each adjustment, however the C-Clamp is there to provide that insurance.
3a. I assume you have to tighten up the C-Clamp as you tighten up the nuts.
4. Once you have 2" left on the front gap of the spring from the dip of the helper spring where the shackle rests to the top of the Ford spring, verify that the thread length on each side of the shackle is equal from the bottom nut to the end of the shackle
5. Undo the C-clamp, the front side of the spring is done.
6. Repeat 2-5 for the back side of the helper spring
7. Drop the levelers
Repeat 1-6 on the other side of the rig.
Am I missing anything? Feel free to edit/amend this until we have it right.
Any value in spraying the threads w/ WD40 in case they have some gunk holding them down? I definitely don't want to strip anything as I work through this. My threads are in pretty good shape (visually).
This doesn't seem like an incredibly difficult job.
