It's been a minute since I happened to glance under my truck on the way home from a trip and noticed that the rear axle housing was cracked and leaking at the passenger side leaf perch. Luckily though, the sinking feeling I had at the time has faded, no doubt due to the smashing success of the patch I installed - following Ryan's @Reh5108 lead - which has been trouble-free ever since. Of course, the only reason I installed the patch was because it was going to take a long time - six weeks was the estimate - to get…

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.

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 recently discovered a dreaded gear oil leak on my 4Runner, and knew it meant only one thing - it was time to change the rear axle seals (and bearings and brake shoes since they were now saturated with oil). In addition to the story of the 4Runner repair, and later the Tacoma repair, I figured a detailed set of instructions for anyone wanting to tackle this themselves would be nice to put together, since it's hard to find that written down in one concise place (maybe even impossible before now). This is of course based on two amazing resources -…
