Hi there all,
I'm planning on changing the differential bushings and subframe bushings in the future (after I recuperate financially). I bought some differential fluid with the intent on changing it now. My 03 track is reaching 100k miles, and my plan is to change the differential and subframe bushings by 150k. If I change the differential fluid now, am I wasting it? In other words, when changing the differential and subframe bushings, will the fluid need to be drained? Thanks all.

 

Just do it now, and you'll be fine for the rest of the car's life. Any idea how old the fluid is that's already in there? There isn't any reason to drain it when doing bushings unless you sit the differential on the ground upside-down.

 

Long story short, no

 

Thanks for the quick reply guys. I have no idea when it was last changed, so I'm assuming it never was. I'll go ahead and do it then. Expecting an improved Zxperience soon!

 

You won't need to just keep it right side up so it doesn't drain out of the breather tube.

 

Don't expect any marked improvement in the feel of your VLSD from a fluid change alone. What viscocity and brand of differential fluid are you using?
