I don't think any automobile manufactures undercoat and rustproof their vehicles. I wish I had the time to get carried away like they did in that video but I've done pretty good with cans of rubberized under-coating, Transtar Amber rustproofing and a few cans of Surface Shield every fall.  I live in a nasty rust-belt and my 2011 Edge was still in amazing shape when I sold it a few months ago.

Found a video for an MKZ same exact rear suspension. I missed the loosen the sub frame bolts. Now to just try it.    

I am on day 2 buying spring compressors to try to reinstall the rear springs on my 2017 MKX. I cannot find a video or any reference to do this job. It seems like I am the only one ever to replace these springs. Anyone have any insight?

I am the original owner of my 2019 Edge ST and it just turned 100,000 miles today. I know I'm due for spark plugs, but wanted to ask about the serpentine belt(s) and pulleys.   Is there one main serpentine belt for everything, or are there two, with one belt just spinning the AC Compressor?   The motor is currently very, very quiet, but I'm thinking about replacing the belt tensioner pulley and idler pulley. I assume there are just two pulleys with one being the tensioner?    If there are two belts, is there a separate belt tensioner for the AC serpentine belt?   Is there anything else that I'm missing at the 100k interval?    This car has been absolutely trouble-free with only one return to the dealer to replace a USB port that stopped working. No leaks, no oil burning, everything still works (well, except the sunroof shade broke last summer  ).   Probably the best vehicle I've owned.    Thanks very much for your assistance.    Regards,    Rick  

I understand all this and what rust can do and I do not want to cover the rust. That area at the bottom of the door is very difficult to cut and re build and that's the reason I posted here to get info from other members. Hopefully the dealer tomorrow will tell me how it can be fixed. Thanks

Doesn't matter which end he sprays in.  If you see rust, then you have rust, plain and simple.  You will not know how much rust you have in that door unless you take the door apart.   Covering the rust with any type of lubricant / sealer / anti-rust compound does not make the rust go away.  It masks it. The only real way to eliminate the rust is to cut it out and you will have to take a good section of the rusted area and the surrounding non-rusted area out to ensure you get it all, or as much as possible.   Rust is a cancer.  What you don't see is what can kill your car.

Good point mate but I thought he sprays the inside of the cavity at both ends?  Anyway tomorrow I go for an oil change and will see what the dealer has to offer Thanks

The only problem with the video above is that you are now spraying over the rust that is already there.  The best time to do that is when you first buy your brand new car.

I want to get IPC climate control working

Is there any hack or alternative software to install that I can change the layout of the touch screen? I hate the current layout. For example, see the attached. When I want to go into climate, my eyes and finger must travel a LOOOOONG distance on that display and that is terrible in of itself, its also distracting and dangerous. 1. say I want to turn off the climate system. Finger presses Button on bottom, finger to top off button, finger back to bottom to close the screen. Ridicoulous 2. say I want to recirculate the air. Finger presses Button on bottom, finger to top circulations button, finger back to bottom to close the screen. Ridicoulous   UGH! I have no clue who allowed this navigation nightmare in the first place, but it sucks. Plain and simple.   So now, in all todays day and age, is there a hack to this software where I can override and change the layout to my liking?
