Spring adjustment details.....and you'll need these details for bolt repair.


PLEASE NOTE THAT IF YOU DO NOT FEEL COMFORTABLE, DO NOT ATTEMPT THIS PROJECT.....AND PLEASE UNDERSTAND THAT YOU ARE DOING THIS AT YOUR OWN RISK.....this is just the way I've done these repairs in the past.


It's important to fully understand where the loads are at all times when supporting the roof. Sometimes the springs are supporting the roof, sometimes springs + come-along and sometimes the 2x4's.


If you are just adjusting the springs you can remove the helper springs and cover plates and cut a 2x4 to length and lay in the channel to support the roof. When you relieve tension on the crossbars/extension springs the crossbars will push against the end of the 2x4 and the roof should be supported robustly.

Since you are replacing pivot bolts you'll need each corner supported. You will need the crossbars unloaded to be able to move them for hole alignment, so the 2x4 in the channel doesn't work for pivot bolt replacement.

..and obviously just do one side at a time for safety

There is a large hole/circular cutout along the inside edge of the channel for one end of the come-along to attach to; you'll have to carefully pull back the upholstery at the hole to get to it. It's on the inboard side of the channel away from the extension spring.

You need to hook one end of the come-along into this hole and connect the other end to the end of the extension spring. I use a motorcycle tie down (just for the hooks on each end) to get into the hole in the channel and the loop in the end of the spring. The hooks on the come-along are big/bulky. I hook the tie down hooks to the spring end and the hole, then connect the come-along hooks to the loops in the tie down hooks.

Crank the come-along until the S-hook connecting the spring to the chain has some slack, then remove S-hook and carefully relieve come-along tension. Now that side of the roof is supported 100% by the corner 2x4's.

At this point the crossbars should have some movement to get holes aligned.


If you are just adjusting springs crank the come-along until you can get the S hook in the second link. Then zip-tie the end link back to the second link so it won't rattle, then carefully relieve the come-along tension. If the roof is still harder to push up than to pull down you can shorten by another link. At some point the roof won't come down very easy and/or you may be bending the crossbars, especially if you have solar panels/other weight on the roof.
