4WD kills you - but there is hope!
When the starter in our 2001 Toyota 4Runner 4WD V6 died (ok a hammer tap got it to turn after a cold night), I decided to try the repair myself.
After watching many YouTube videos and scouring forums like this - I was hesitant because there didn't seem to be any consistency on what worked/didn't work. But some videos showed the starter coming right out and others the brake line bit seemed the most common so....
I jacked up the truck and set it on two stands. Removed battery terminal, the power wire and exciter lead from the starter. With an 18" extender and swivel joint, getting the starter off was a piece of cake.
But it was NOT coming out. I could get it ALMOST out over the stabilizer bar and power steering line, but the dipstick tube welded to the transmission pan blocked it. After fighting this for a while, I removed the rubber panel in the wheel well and unbolted the two brake line brackets. It moved, but not enough. Even after I removed the upper half of the dipstick tube - the manifold was too close to the wheel/spring assembly. That starter was not going to come out through the wheel well. The 4WD was the difference from what I saw in the videos. The spaces are just too tight.
I did NOT want to drain the power steering or brake system to undo the lines and get it through. But based on some earlier posts here, I decided to take the starter apart just to get it OUT. The two long motor bolts came right out and I just cut the short motor wire. In two pieces, the starter came out over the power steering piston/line with no problem.
But I *really* didn't want to try and reassemble the new starter in that cramped and VERY dirty place (lots of caked dust/oil crud). I know I would have gotten grit into the motor housing. On a whim I grabbed the old motor and held it up to the new one. The new one was like an inch shorter and MAYBE a hair thinner. The gear box had a couple small differences.
So on a whim, I got back under the truck and gently tried to get the starter in over the power steering line. I *think* I got it in with the gearbox tilted in first (but can't really remember) and a slight twist here and there - the darn thing slid right into the starter space!!! I didn't have to put any type of pressure on the dipstick tube or power steering line. It was JUST different enough
Then it was trivial to bolt it on and reconnect the wire. Took more time to get the brake lines rebolted than it took to put the starter back on (and the dipstick tube)
SO moral of story - your new starter may be small enough to slip in even though the old starter won't come out. Take the old starter apart, slid it out in pieces and save yourself a whole lot of trouble. I probably wasted 4 hours on a job that knowing all this would have taken 30 minutes.
This is the starter I got:

Can't believe how the truck starts now!
