Am i to assume this issue is more prone in colder climates?

More?

But they still fail, even in places that never freeze. The metal is weak and pulling (rather than the correct rotating lift action) will eventually break the carrier...

The hinge is made of potmetal vs say aluminum billet so fatigue failure will eventually kill the DHC. I recommend putting the zip tie around the weak spot on any X5 door when any door is open for any reason.
If you live where it gets below freezing even if once a year you should also add the anti-freeze fix I've described with the Teflon and grease.

You can find any of my DIY fixes by searching with advanced for thread name has awr-fix. Did that quite on purpose.

I don't remember all the fixes I posted so far but the DHC and actuator as well as as the fuel siphon jet are biggies.

Is this how you grease the gears and add shims under the zip tie?


I watched all your videos and images on iCloud. That that quite involved, great work.
You're the ultimate expert in X5 locks

Now with adding the teflon tape, do you have a link to the type of tape?
My understanding is that teflon tape in very thin, used on threads when connecting pipes.

Can't I just add grease or antiseize to prevent the rivet and metal parts from freezing to each other?

Or just bite the bullet and install a new lock unit and enjoy trouble free working at least for a few years. (Totally against the DIY ideology I know.)

PTFE adhesive tapes are available on many forms.

Well I'd rather fix it once and never have it break again

I guess this tape should do it

Can't you just use duct tape instead? It has great adhesive properties and is pretty slippery

The fix for the actuator solves the problem of the actuator freezing which will regularly cause the break of the DHC. A brand new DHC can easily break when the actuator freezes.

I find the replace everything vs repair anything mentality tragic.

So: you are suggesting: spend $80-90 vs 8-9’ for a repair that is not as strong? (Well with the steel zip tie I guess more like 30’). You suggest that replacing a DHC with a new one gives some significant expectation of trouble free operation, which if used in a sub freezing environment, not true. I have seen a DHC break in less than two months from one good freeze.

If you live where it gets below freezing, mod your actuator so it won't freeze.

That's the fix tape I bought.

And I've also used this.

I tried a test with grease only, the ice that forms acts like a squeegee and scraped it off. I had better luck with a thin film of grease staying when the thin layer of Teflon or nylon between the steel and ice. The ice formed on the steel side but the grease acted as a water repellant and the ice left a tiny gap between the ice and the Teflon.

The force reduction to unlatch the frozen latch was on the order of 100x.

I wouldn't use regular tape. The double sided adesive on the tape adds an insulation layer that helps keep the ice that forms from making a strong grip

Don’t take offense not a swipe other than to point out, my fix is far better than new. It effectively eliminates the design defects of both the dhc (by tuning the brittle joint that breaks into a flexible joint with give) and eliminates the freeze condition of the actuator that sets up for breaking the dhc.
