Hi,
I recently had the transfer actuator die on my '02 SR5 & this repair was beyond my capabilities. No user error, nothing. Just decided to die.
My 4Runner was turned into a 2Runner. Given I'd added Bilsteins, new UCAs, etc this just you know, hurt bad. Not that I'm looking to sell, but pretty much any value in the vehicle, beyond separated parts, felt like it vanished overnight.
Obviously, LBJs, the timing belt/water pump, head gasket failures are all potentially if not usually catastrophic, but...I'm just gonna throw out there the transfer actuator might be up there in terms of pain. It doesn't kill the vehicle, it just removes the one feature that defines the character of the 4WD 4Runner.
Not to mention the expense of the parts & labor -- f'ing yikes. And at least in my area, the availability of the OEM part was nearly non existent.
Anyway, if I'm voting the most painful/unfortunate repair, it's this.
In for a penny, in for a pound with these vehicles. I went ahead and did it. Woof.
The shop is taking apart the old actuator to see why it failed & if they can rebuild it, they're just going to give it to me.
