Unfortunately my 4wd wouldnt engage- ended up swapping transfer cases (huge gamble if the replacement would be good or not... got lucky.

I now have a transfer case from my 04 4.0 that needs an actuator. Any ideas what it is worth? I figure this is a great option for someone to install a new actuator while its out of the car and save a ton of time. I was thinking $200 or so?

I had a 2002 benz G500 before, those had problems with engaging 4lo as well. Shift motors were fine, modules had bad grounds and dealer cost was $700 CAD parts only. Luckily with 4gen 4runners its a matter of using a shift motor to keep it operational. Cant wait until Fri to get my truck.

This is eppic work. But reading through many posts, the breather seems to be the issue with lettin in condensation and freezing up the motors and gears

Crazy thought on my part, but wouldnt it be possible to just run a lithium grease spray or some type of lubricant down into the breather hose?! In which it will Coming contact with the dc motor and or anything else the water came in contact with?

Seems the simplest way to come in direct contact with the internals without actually tearing anything apart?!!!

Hello from naper- I read your post and would liek to knwo how hard you tapped if at all and if by slightly loosening was there any fluid that came out? Or is it dry-
