New Excursion Owner, just trying to get it right

[Excursioned]

First of all, I'm a new member to the site. However, I'd like to thank the users of this site, as well as the Diesel Stop website. Your information was my guide, when I went looking for an Ex. Thank you all!!!
Ok, been tinkering a bit, found an all but obliterated rusty fuel filter(repaired+cleaned), but may end up needing to drop the tank and clean it. Going to tackle the oil change this week as well, and then look for a tuner.
My front wheels, look like they are toed out sometimes, and I'm not sure what that's about, but I'm thinking it may be the bearings??? Brakes, are sometimes a bit shaky(they vibrate), may just need new pads. And lastly, three of the four doors have a tough time locking and unlocking with the button and keyfob. Hopefully I can fix this without replacing ALL of the actuators?
Overall, I LOVE this truck, have improved my mileage from 8 mpg with a gasser 4x4 pickup to 12 mpg with the PSD Excursion, and have space for the family!! Can't beat it. Any suggestions to the above issues will be greatly appreciated

We can fix your suspension and brake problems, suspension if its a 4x4..first have it checked out by a good alinement shop..Ball joints and Unit bearings..if needed first.

Not 4x4. Unfortunately the first truck that I've ever owned that's not a 4x4. The front end sometimes looks perfect, but has the toed out look at other times. An alignment will likely be in my future, but I'm trying to hold out for a couple months. I'd like to change the shocks, and install a sway bar. I plan to have an alignment performed after those are added. I have yet to put it on a jack, and give it a wiggle. But am hoping someone else has seen this on thier truck, and could post a solution.
