Fix or Get another vehicle?

I blew a spark plug out of my 01 Ford Sport Trac the other day and had it towed to my mechanic who attempted to put in a Sav-A-Thread insert into the same spark plug hole about 3 weeks ago. It'll be $2000+ to have the cylinder head removed and machined out, or more of a new head is needed. The truck has about 250k miles and was still running well. It has been well maintained but is it worth it to have it fixed? Would it be better to look for another vehicle (I'm a college student on limited income) or could I attempt to replace/fix it myself? I've done most of the maintenance myself but this job seems over the top.

Will my slant reck my car?

I have a designated parking spot at the apartment building I'm staying at, And my spot has a little slant, it only looks like its at my spot but its not big but its big enough that my min van (ford Windstar) leans more on the side with the slant I'm only at this place till next March and was wondering if that harm my Vehicle? Or my tires? The van is moved everyday but I have tried to move over closer to the other vehicles and no luck I'm still slanted. And if I park somewhere else my van doesn't slant

Dash noise after remote starter installation from dealer?

Dash noise after remote starter installation from dealer?

Added (1). Just got my car back today after ford dealer installed a remote on my 2005 ford five hundred and now there's a rattle noise in my dash that wasn't there before. I call up the service guy and he immediately responds that they wasn't under my dash. I'm assuming he meant because they were in the steering area instead. Is it possible the remote installation caused this rattle noise?

Big Jeep.Renegade. 350/5.7, Ford Manual Trans, Rockcrusher D60's on 41 s. Mystery Hub/ Axle Seals?

The rear axle seals fit the hub, but the inner diameter is a wrong fit to the axle tube. Its close enough to look good but No seal… Yup, new supers stinking and looking like like diff fluid all over.
It's a Rockcrusher D60 center, but I'm not sure of the manufacturer model axle end's welded in place.

The axle tube sealing surface miked out 70mm (2.75")

Anybody know how to get the correct Axle seals?

Car battery seems to be stuck in place. I have removed the terminals and all of the bolts?

The vehicle is a 1995 Ford Aerostar van (regular one, not the extended one). There's what looks like a plastic base under the battery that is perhaps holding the battery in place, and I have removed the bolts from the side of this base, and I have also removed the battery terminals. After doing this I'm able to lift the battery up from the front, but it appears to be stuck in place in the back. I have not seen any bolts in the back, so I don't think there are any, but it just seems like the battery won't come out, like it is stuck to the plastic base.
I see something in front of the base that looks like a thin metal rod with a metal washer attached to it, but this just looks like it is part of the base, not connected to the battery.

How to remove rust from car?

I've got a few minor surface rust spots on my car (to be expected with a Ford!) One on the front passenger sill where the paint has peeled away a bit and the metal has begun to rust, and a couple of tiny wee bubbles on both rear arches I think. There's also a minute one on the very front of the bonnet. All guides I find online say to sand/grind the rust away till you get to clean metal, then clean, prime, paint, polish, standard procedure. I'm not particularly fussed about it looking good (nearly a 10 year old car), I just want to nip it in the bud and get rid of the rust before it spreads and becomes a problem (had a Ford go to car heaven due to rust in the past).

So can I just have at it with a normal wire brush and sandpaper? Don't really wanna go messing about with actual tools and the like, and don't wanna mess about with chemicals aside from the cleaning and the painting.

As I say, I'm not fussed in the slightest about it looking patchy when I'm done, it's black anyway so shouldn't be too noticeable.
