awning

[Joede7458]

My large patio awning has 2 locking knobs on the upper support arms.
One of them doesn't tighten up anymore. When you turn it, it feels like the nut that it threads into has come loose and just spins with the knob.
I have tried to remove the support arm and divide the two halves so I can replace it but the two pieces will not come apart. Does anyone know if this is repairable or does the entire support arm need to be replaced?:

It has a nut in there that square or like a 6 point nut, when you slide the small arm down there is one or two allen screws in the end of main arm remove those and it will come out you might have to raise the main arm to get room for it to come out the part left on the unit will have the part in that you need to replace it can be seen in the end, the screws that is used are crimped on the ends to prevent them from falling out but they will come out.

You will need to buy a rafter support knob kit (knob on bolt and locking nut) and cut off the old bolt (hack or reciprocating saw) and install the new knob and nut; then re-assemble.
