So I noticed that 3 of the coil springs on my ramp door were broken (that explains why the ramp seemed pretty heavy). After multiple back and forth calls to my nearest Keystone Dealer with little progress, I called Lippert direct; who knew they made the coil springs too?!?!
Ordered three replacement coils ($22 ea) and got them in 3 days. Install took about 2 hours but was pretty straightforward.
I removed the "hinges" using a T45 socket for the frame plate bolts and a 1/2" socket for the door plates. Once off, I simply slid off the broken coil springs and replaced with the new ones; using a little silicone to ensure a good seal. Greased all 5 of the zerks and it's back to new (well, except for one of my stripped out t45 sockets... A breaker bar gets much more leverage than a wrench
I was very relieved to see no water damage in the holes and no rot in the surrounding area
Just thought I'd share....
