Rear Diff Breather Relocate Mod
Did a quick diff relocate before I went offroading the past saturday and luckily I did because it poured and lots of water crossings.
Parts:
Toyota Part # 9040451319 = Union Fitting
Toyota Part # 9093003136 = Breather Plug
6 feet of fuel line, ID 3/8", OD 1/2"
2, 1/4" 5/8" hose clamps
Teflon Tape
Zip Ties
Tools:
deep 14mm socket or wrench
deep 12mm socket or wrench
knife
How to:
Unbolt the current breather which will most likely be rusted, dirty, stuck open or closed (especially if you live in the North East) with the 14 mm.
This looks bad...maybe I should get the diff flushed?
Side by side...new one looks cheap. Might go and get a metal oem one soon. Not sure why every write up I see they say the plastic?
So I put some teflon tape around the end of the Union fitting, stuck the 3/8" hose on it and clamped it down.
Then make sure the hose doesn't go down anywhere (keep it going up). Now just start running it up to the gas tank door.
Take rubber boot out of gas tank door. The pin that pops the door open twists and pops out. There will be thin metal clips around the outside metal and inside metal that holds the rubber onto the truck.
Run the hose up and through and you will have a bit extra sticking out if you got 6 feet.
I rushed here because it was the night before I was going offroading, I will get back to it and clean it up. I basically cut a hole in the rubber, could not get the smaller inner ring to sit right with the hose now next to the gas spout. Clamp the Breather plug on the end of the hose and put everything back together.
