Anyone who owns a 4WD Toyota and has dealt with the drain and fill plugs on the IFS front diff knows that they generally suck. They use either a 10mm or 12mm hex key, and that can be a problem for many reasons: The recess that the key fits into can easily get filled up with crud. If the recess isn't cleaned and the hex key doesn't fully seat, it's easy to round over. Hex key's aren't generally all that long, so it's hard to get the leverage needed to loosen the plugs. The plugs can get extremely tight, making…

Well, the Tacoma got a new fuel filter today. It's a part I've had sitting around for maybe 18 months now or so, just taking up room in the garage. Because, who needs to install a new filter when the one that's on there seems to be working just fine. Right? Well, it finally dawned on me why they call it preventative maintenance, and I figured I might as well get it done. Interested in doing this yourself? Here is a handy little how-to that lists the tools and parts you'll need: How-to: Replace the Fuel Filter in a 96-04…

When it rains, it pours! It was only a few weeks ago that I replaced the rear axle seals on the 3rd gen 4Runner. No good deed goes unpunished however, and it was only a couple days after doing the job that the same failure happened on the Tacoma - only this time, I was in Canada. Luckily for me, I already had a well thought-through step-by-step list of exactly what to do, and the muscle memory of doing it once twice already. Step-by-Step: Replacing Rear Axle Seal & Bearing on a 1st gen Tacoma w/ABS (or 3rd gen 4Runner)…

TL;DR - I have oil leaking from the transfer case where the front drive shaft attaches.

TL;DR - The rear axle seal replacement seems to worked beautifully and there is no more leaking at all.

Well, as I mentioned previously, our last family camping trip was both a success and a failure. I mean, the camping part was all success, but noticing that my rear axle seals were leaking when we got home - that part was definitely a failure. The telltale oil streak of a blown axle seal. My first order of business was to address what I hoped was what caused the seals to leak in the first place - by relocating the rear diff breather. With that out of the way, it was time to address the actual problem - so I…

I have a confession to make: I procrastinated this job and it may have cost me. So let's back up for a moment. See, this was a mod that I knew I needed to do to the 4Runner as soon as I got it. Toyota has conveniently placed the rear diff breather right on top of the rear diff - pretty much as low as it can go. All well and good except that it's not at all well and good. In that position, not only can the breather can suck water into the diff when submerged in deep water,…

TL;DR - Couldn't be happier. I was considering getting some CVJs to replace my CVs, but I don't think I will anymore.

Just to set expectations - there are no amazing photos in this post. Actually, there are no photos at all - it's just a story. A story of how my day started off one way, and ended another. Come laugh at with me, and enjoy! So, today I was going to work on the 4Runner. I've been getting it into shape so that it can become our family adventure vehicle and daily driver. As such, it's getting a lot of love in the "let's make sure that key parts are in known condition" department - today's work was going to be…

TL;DR - I think I often overlook the little stuff that I take on trips that just does its job, or that may not be used every trip, but is really handy when the time comes. A few of those things saved the day this time and I think it's worth highlighting their value.

TL;DR - After rebooting my CV axles with Toyota OEM boot kits, I am extremely happy. I think this is absolutely the best way to go - even better than custom boots or extended boots from CVJ or doing the boot slide mod.

People often assume that everything is easy for me. That I just go about doing things, and usually doing them well. That's sort of the case, since I've had a lot of experience doing different things in my life and I tend to pick things up quickly, but I think it's important to recognize that even for people who seem "good at everything," not everything is easy. Getting in there and trying things can still be both hard and rewarding, no matter who you are... I don't know why, but I've been super nervous about changing my spark plugs and…

It was just a couple days ago that I noticed my front diff was leaking. Actually, I noticed it only because I was replacing my AC idler pulley for the second time in a month - having replaced it on The De-Tour last year and recently again with less than a week of the F.U. Rain trip remaining. I sure hope this time lasts longer than a week on the trail and a few muddy water crossings! But that's not what this post is about - this post is about my front diff. While I was under the truck with the…

This is a long, wordy post. Sorry, and enjoy the story. As we drove the several-hundred-miles to eastern Oregon on our recent trip to Owyhee and the Alvord Playa, all was not well with the Tacoma. Four times - each time after three uninterrupted hours of driving - there would be a sudden sound of something that sounded like a bearing "spinning up." The sound was disconcerting enough that I'd immediately take my foot off the gas, and the sound would slow - eventually ending in a clunk and everything would be "back to normal." Everything that is except my…

Well, the good news is that we were successful. It may have taken 14 hours, but the Dan's (@drr and I) were triumphant in our first attempt at a timing belt self-service to each of our 5VZFE's. But oh, how we're getting ahead of ourselves. Let's back up say... six months. Just for a moment. Back in January, I was sure that I was going to have Toyota do my 90K mile service at the end of the summer, after this year's trips were in the books. I knew I'd be a little over 90K, but I figured it was…

I was ready for adventure - running solo, I was returning to Death Valley, having only just wet my appetite on our first trip back in January. With 2500 miles to go, I knew I had a lot of driving ahead - but I was ready - or so I thought - when, less than 50 miles in, the Check Engine Light (CEL) came on. I've covered the details of the first hours of diagnosis in my Back to Death Valley trip report, so if you haven't read that (and are interested), I'd recommend starting there. The plan here is…

Our trip to The Maze was awesome. However, you may recall that near the end, we hit a whoops a little fast, which led to me peering under the truck a few times on the way home to try and determine what the god-awful shake was that we were feeling in the accelerator, seats, and - after 15 hours on the road - our bones. I wasn't able to figure it out on the drive home, but the next day I spent some more time under the truck and noticed two things: The rear diff pinion seal had started leaking…

February 21, 2018. Not all that long ago, the truck got a gear change - from the 4.10 factory gears to 4.88's - meaning that it's now easier on the engine to turn the bigger tires as it climbs up hills, over rocks, and generally towards adventure. Within a couple weeks of the gear change, I'd driven far enough to get 500 miles of break-in complete on the rear diff and changed the oil - and everything there seemed A-OK, which was nice. And then on our trip to Death Valley, we ran as much as we could in 4WD…

February 21, 2018. How many miles do you have on your truck? If you're anything like me, you'll answer this by looking at your odometer, reading a number, and concluding that you have that many miles - 83,078 miles in my case. Like me, you're wrong. Your odometer is lying to you. And so is your speedometer. I covered why that is here - go read it. I'll wait. Speedometers, Odometers, and Gas Mileage – All Lies! OK, welcome back. Or not if you're like me and just skipped over that last link. Let me try to recap: The reading…

February 21, 2018. I've had a rattle for a little over four months. I first heard it (I think), when returning from The De-Tour at the beginning of October, or else maybe a week or so after that. It sounded like a loose heat shield, or other piece of sheet metal, rattling away under the back half of the truck. But I knew it wasn't a heat shield - it only happened at speeds above about 15-20mph, and changed when under load (vs. coasting) and there were certain throttle/speed/terrain combinations where I could almost get it to go away. Of…
