A big thing I do with my wintec saddles is get the girth points changed over to leather. They always degenerate quickly and the plastic cracks. Not sure but that may be where is it squeaking as there is a fair bit of pressure.

 

I've had my wintec 500 dressage for about 5 years now and my girth straps are synthetic and only just starting to crack slightly. I take really good care of my saddle, but I'm sure others do too, perhaps I got lucky for them to last this long lol!
My saddle sometimes squeaks. I'm not too sure, but I think it has to do with how the saddle can come apart when you change your gullet plate. I always make sure everything lays down inside correctly before closing it, as I've made the mistake before of not checking and found it would squeak... not incredibly loud, but enough for you to get irritated lol.
Good luck in finding your squeak!

Really? Well your lucky then!

Actually, when I think about it mine probably lasted a fair few years, i've had my original Wintec 500 for 8 years... lol. My new one hasn't started cracking yet, but having synthetic pints again makes me remember how much I hate them!

I love my wintecs :]

 

Yup, baby powder / talcum powder. Sprinkle it between the panels. I've "heard" it work. Shouldn't need a whole lot -- start conservatively and apply as needed only.
