ECGS bushing, diff fluid loss

So I plan on doing ECSG mod when I have the truck up for suspension work. I was just curious if you guys just did the bushing and didn't worry about the fluid loss? Flush and replace the fluid after install? Added a little to place the fluid loss?

I haven't done this before but have watched a few videos, doesn't seem like a lot is lost during the install, but wanted to see what you guys did

 

Top it off or just fully replace it. Their isn’t much diff fluid in the front diff anyways. I did mine right at my interval for changing it out anyways. Whichever is more convenient for you.

 

Only 30k miles on the car, but since I'll be working on it, might think about just changing it

 

Best is to be prepared to drain n fill. There's a chance that the head of the tool or one of the rollers in the bearing can get in the diff. Then you have to open the drain anyway.

 

30k is a good time to change it out anyways. Especially if it gets used as a truck or see 4wd use often.

 

I watched some videos and they just jacked up the drivers side fairly high and barely lost any fluid at all.
But I agree with @Texoma though, make sure you have the tools and oil you’ll need for a full fluid change in case something goes south....

 

Jack up the drivers side before removing. Gravity works well.

 

Just drain your diffs and transfer case and replace the fluid. 30k isn't bad for a first change if you use 4wd or tow.
