Chirping traveller doors

[Grumpy21]

I’ve had 4 travellers and all have had chirping rear doors. My current one is by far the worst, it chirps like a budgie on heat!

I’ve had minimal success before with bending springs, tightening, fixings, adding tape and foam here and there and lubricating bits and bobs but I’ve never achieved anything like total success

Any tips and ideas before I commence battle this weekend?

Thanks

Get a real budgie and keep it in the back!

Squeeky floor boards can be cured by putting talcum powder on the joints.
Not sure how you could keep it on vertical doors though.
