On Saturday I went to go pick some morels up towards Mt. Hood, and had the pleasure of the first off-pavement trip in the 4Runner. It handles well, has great visibility, and I was generally very satisfied with its performance... that is until I shifted into 4WD.
In one of those steep and loose sections, my rear tires started spinning a bit, so I came to a stop, put 'er in neutral, shifted to 4LO and released the clutch- only to find my rear tires spinning, and I was going backwards. NO 4WD! This was not what I was looking for. Especially since my fiance was in the car, she was a bit nervous to begin with, and also asked the (admittedly valid) question just moments before "are you sure you know this truck well enough to attempt this [unimproved] road?" To which I replied something like "sure, this thing runs like a top."
At the base of this road was a friends' house, and he was home to help me give me a quick look at the front end when we came down. After driving up a very loose and steep grade to the point of spinning, I turned the wheels so he could see the drive lines. Sure enough, when I shifted into 4WD, they were spinning. So, the lack of 4WD can be attributed to those STUPID automatic locking hubs that Toyota put on some of their trucks (including my 4Runner) in the 1980's.
There are a whole pile of issues with the automatic locking hubs from this era, so instead of fixing them, my first 'mod' to my 4Runner will be replacing them with manual locking hubs. The first thing that came to mind was going with a set of Warn hubs. This seemed like a good idea, but after talking to Warn about their hubs, as well as reading up on some opinions from other sources and other forums, I decided that the best scenario was to replace them with a set of Aisin manual hubs- the same ones that many Toyota's came with.
After searching around a bit, I found some folks who sell them 'refurbished' for about $300, or will refurbish ones that you send them for $100. I figured that having mine refurbished sounded like the good way to go, so I called the local salvage yard. They wanted $60 each for the hubs, so I went up to have a look. When I got there he said that he was really sorry, but the ones that he thought he had on the shelf weren't there. However, he does have a front end from an '87 4Runner that he'd go pull them, off of for me if I wanted to wait for a bit. I suggested that instead of waiting, I just go have a look, and if I liked them, I'd pull them off myself. The hubs looked good, so I went about removing them. On top of the hubs, I pulled the bearing retaining washer, the two 52mm axle nuts, and the star shaped locking washer.
When I got home to get the address of the company that I was going to send them to, I realized that they used the term 'refurbished' to describe taking the hubs apart, degreasing them, regreasing them, and putting them back together. It also includes a new powdercoat on the cover and dial. As far as shop time goes, I'm sure it makes sense. As far as $100 plus shipping goes, I'll just do it myself and chock it up to a few hours getting to know that part of the 4WD system of my truck a bit better.
Coming soon- pictures.
