New 4runner owner. So many questions

I am a new 4runner owner. This is also the first vehicle that is more or less my own. I did quite a bit or research before settling on this vehicle and a big thanks to 4-Ripcord for the 3rd gen buyers guide. I have lots of questions, some of them 4runner specific some of them are more general. If any of them are answered I will be more than grateful.

The vehicle: 1996 4runner SR5, 3.4L v6 4x4 automatic transmission. 264,000 miles and I picked it up for $4,500. The previous owner was a toyota technician and I believe the 4runner has been serviced at a dealership for most of its life. It appears well taken care of. The engine is clean, no leaks that I can tell and most everything is in good condition.

My driving conditions: I live in the mountains of British Columbia. It is 8 miles down the most heinous dirt road I have ever lived on to town. The roads where I live are mostly smooth highway or backwoods logging roads. They don't salt that much because down in town it usually rains and where it does snow is mostly just plowed and sanded.

What I have done to it: I replaced the PCV valve and grommet. I had the transmission fluid and differential fluid changed along with the oil change. I replaced the air filter in addition to a couple burnt out LED's and a marker bulb.

The big question: This is the highest mileage vehicle I have ever owned. How can I get the most out of it? Should I just drive it into the ground, doing just enough maintenance to keep it rolling? Or if I do preventive maintenance and try and keep everything as it should be will it go the distance?

MPG: I am getting pretty terrible mpg's. I go about 200 miles before I have to refuel, this roughly when the gas light comes on. I think this is a bit low even with all the vertical feet of climbing that it has to do every day. There is no engine light on, but perhaps the O2 sensors are bad. I don't know if they have ever been changed (it looks like $80 a sensor so I am hesitant to change it if it doesn't need it). Is there a way to check the O2 sensors myself? I also plan on changing the fuel filter when I find the time. And maybe run some SeaFoam right before my next oil change.

Brakes and tires: The tires that came with the vehicle are 32x11.50R15LT. They are a bit big and I don't go mudding, however I have come to fall in love with them anyway. I think they are contributing to my terrible gas mileage. I was very interested in doing the tundra brake upgrade because I am breaking so much when driving (rolling) down to town. After some research I realized that the calipers won't fit on 15" rims. I also need winter tires in the next month or so. Here is my conundrum, do I keep on going with the standard 4runner brake set up and get winter tires for the 15's or do I go out and buy bigger rims so I can fit the tundra calipers on there. I was told when I got it checked out that one of the front calipers is really sticky and will need to be replaced soon. Are calipers something that need to be replaced at the same time? For example, can I replace one caliper or will I need to replace both at the same time? I like the look of the big beefy tires, but I have heard that as far as winter tires go, the thinner the better in order to cut through the snow and ice. Any suggestions here? The last question is what sort of maintenance needs to be done to the rear drum brakes to keep them ship shape?

General questions: The road I live on has more washboards than the 19th century and pot holes that could comfortably fit a baby. I am afraid the whole vehicle is just going to rattle apart. I believe it still has the stock suspension and springs on it. Is there anything I can do to prolong the life of my 4runner on these conditions? New shocks? Different shocks?

There is shrieking noise when I am accelerating between 15 and 30 mph, I was told this could be a hole in the muffler or bent bits in the exhaust manifold (I don't really know). Any insight here? Perhaps it just needs some Tiger Patch tape?

Everything that I can do to my 4runner right now comes down to resources. Money is very tight right now and winter tires are pretty much all I can afford with a little extra left over to keep things running well. In a perfect world I would fix everything I could, but it doesn't work like that right now. What should I prioritize in terms of general preventive maintenance? Finally, any general tips for a new 4runner owner would be awesome. Thank you for reading the wall of text.

First of all, Welcome to the family.

I saw people in here or others 4runner forum ride their 4runner with 400 000 miles on it.
This car is invincible. Just trust her. 4runner is one the easiest car to maintained in my life. There is such a basic maintenances to keep her in good life conditions (Sparks plug, sparks wire, throttle body clean, MAF sensor cleaning, radiator etc etc...)

And for the gas milage, I would say it's normal. I have around 250 to 285 miles with my lift, stock tires and wheels.

What I can say, take it easy, do your maintenance step by step and she will guide you :)

for suspension if you dont' want to get any lift and want to bring back the stock ride, just invest in some KYB, they are OE and really close to stock ride and pretty cheap.

I have mine 1997, with 140 000 miles on it, and still strong and capable.
 
and for your road conditions drive.

if the Ball joint has not been replaced, just do it and you can rock her in those pothole for some 100K + more...

:welcome:

If you treat it well (which it seems like the previous owner did) it will treat you well. I've got almost 300k on my 91 Pickup with the 3VZ-E engine, which was possible one of the worst engines Toyota made, still leaps and bounds beyond other manufacturers though. Don't be put off by my low post count, I'm new to these forums but not to Toyotas.

1. MPGs: Because you are running 32's your MPG's are higher than recorded. This link might be helpful: Bigger Tires and Gas Mileage: How to determine actual gas mileage?. So going from 31's (stock) to 32's means you are off roughly 3% on both your speedometer and your odometer. For example, 17 MPG becomes 17.51, etc. Or whatever that is in kilometers.

2. Wouldn't worry about the tires, those mud tires should do just fine. If you don't like the extra road noise you can go with All Terrain tires. I drive the Sierra Nevadas in the winter with my truck and never had issues with 4 wheel drive and A/T. You might be losing some gas mileage because of the tread, but I'd focus on the maintenance items (clean MAF, replace fluids, etc.) and you'll notice more differences there.

3. Brakes: My 98's rotors are going bad anyway, so I'm doing the swap. Looking into the aftermarket parts since I could do it for $250 or less if they check out ok. I'd say if you have to change the calipers, do the swap. If not, keep them as is. Calipers are not a regular maintenance items. Drum brakes are pretty easy on maintenance, you might need to bleed your brakes though (suck out the old fluid, replace with new fluid, then bleed the line that goes to each brake, don't get air in the lines though!).

4. New shocks and new struts will do the trick. I'm also not planning on lifting or nothing and it sounds like you are not either so replacing with OEM shocks and struts is the way to go. If you end up getting off-roading shocks like Bilsteins it'll be more stiff and you'll feel the bumps more, but they are great with lifted trucks since they provide more stability.

5. Exhaust: Yeah that could be a very small pinhead leak. Take yourself a 3 foot (1 meter?) section of hosing and "listen" to all the exhaust pipes while holding the other end to your ear. You'll be able to find the source of the noise if it is indeed an exhaust leak. Also listen for a rushing air noise since it might not be loud at idle. Either that or run seafoam through the intake and watch for the smoke to leak out (an exhaust shop will do a similar process to find leaks) and search around with a flashlight.

6. Prioritize what you can afford. Bleeding brakes takes $5, 30 min and a friend. Sparks plugs will run about $25. Cleaning the MAF is free. Start there and then move to the pricier items.
