    Hi,all

    I have a 1982 Shasta 165 with external lift arms. I just ordered new Springs for the lift arms and I have a good idea oh how to remove the complete arm assembly.

    I need help with how to remove the spring from inside the lift arms!!! I’ve been doing a lot of searching and can’t find a diagram or exploded view of how the lift arm itself is assembled.

    Can anyone weigh in on this!? I’d really like some insight on how to do this before diving into it.

    Thanks in advance!!!!

[::)]

    So first you have to remove the arms. “YOU MIST DO THIS WITH THE CAMPER POPPED UP!” Springs have the least amount of tension when the arms are fully extended.

    Get a piece of timber or 2x4 to brace the top on the corner your removing the arms. I cut a piece slightly taller than the bottom of the roof and used the tounge jack to lower the corner of the roof onto the timber.

    I removed the side handle looking brace that holds the arms in place.
    Then remove the hardware that holds the arm on. I then had to grab the spring inside the lower arm where it attaches at the bottom mounting bolt. Pull on the spring to remove the leftover tension and slide,wiggle,and pry the arm off the mount points.

    After removing the arm you will have to remove the pin that holds the two legs together. Then separate the arms and replace the spring. Reconnect arms and replace the pin you removed. And reinstall back onto camper.

    The pics above show you the pin you have to remove to separate arms. I will post more pics tomorrow.

    So... on our pop up there are eye bolts that attach the spring to the frame. We were thinking we would remove the eyebolts and replace the springs that way. I havent ordered the springs yet. It is difficuly to raise and comes down dangerously fast.

    Our ms was extremely heavy, me and the wife could barely pick it up and it was very hard to lower. Really needed 4 people on each side. After the springs I feel confident my wife could lift it up herself if necessary.

    Can you post pictures of how the springs attach?

    My springs are inside the arms. There are bolts that stick out of the camper one on top (roof) and one on bottom (box) and go through the arms and a nut on the other side to hold the arms on. The spring loops around the lower bolt inside the arm.

    Hi, I have been following your post. We have an old 1983 au wagon with external arms. The arms don’t seem stable and two have broken.
    Do you know where I can get new ones. Seems to be similar to the ones you have (or I think they can work).
    Thanks

    I am really happy that I found your post. I’ve been looking to do the same thing with my camper. At the moment the springs don’t work(not sure they are still in there) so I have to lift it every time I want to pop it up. Next project will be replacing the springs. I’ve been putting it off because I didn’t want to have to replace the whole arm. Thanks so much for the information.
