What is the reason behind draining the transmission fluid when changing out the half shaft? I changed a half shaft on a van without draining the fluid and it went just fine. Anybody know if it is absolutely nesessary to drain the tranny fluid i.e. will there be problems down the road after the axle change if the fluid isnt drained for the change out?

 

uhh..I have never drained the tranny fluid to change a CV....nor have I ever heard anybody say to.

 

I have a crappy haynes manual that says you should do it. I did one on an odyssey not too long ago and that manual said also to drain the fluid for the change. It wasnt a haynes manual but something else. I didnt do it because I didnt see the point. just wanted to know from someone else who agrees.

 

I wouldn't do it. I drained the fluid from my 5-speed, and had to pump the clutch about 500 times to get the air our of the lines. Pain in the butt.

 

that doesn't even make sense....

 

There's no real reason for the fluid change other than it's convenient and you'll likely leak some when you pull the half shafts.

Just as a side note, aftermarket axles for civics are so cheap ($40 a side) that I'd probably just throw a new axle on rather than replace the joints.

 

I found that out pretty quick. Cheaper to get one at a parts store new then bother ebaying or junkyarding it. As far as draining the tranny goes, I've drained and refilled my manual tranny oil at least once on 3 different hondas I bought and didnt have any problems with air in the system.

 

Sorry about that. Wrong part.
