For the last 3 years my 4 wheel drive is hit and miss meaning some times it worked and some times it didn't.
When it didn't I could usually get it to engage with several pushes of the button.
Well this year no luck. Push the button and all I get is the flashing 4x4 light on the dash.
I tinkered with it and have it narrowed down to the front drive axel actuator.
If I tap on the actuator with a small hammer it will engage correctly.
So I read a post here and they were talking about greasing the actuator and mentioned di electric grease.
I started to pull the actuator so I could tear it apart and look things over but as soon as the seal between it and the axel was broke loose it started leaking fluid and since I'm not sure what type and weight it takes I quickly tightened it back up.
A few questions.
What type and weight gear lube does the front axel use?
Can the actuator be serviced with out removing it from the axel?
I'm assuming that the grease they were talking about goes inside the plastic cup that is held on with 4 Philips screws and is it di electric grease or just regular bearing grease?
Is there anything else I need to know about the removal/repair of the actuator?
If I cant get this actuator to work where is a cheap place to buy a new one, are there any aftermarket or does it have to come from Toyota? Anyone know the part #?
