Hello, i'm new to this forum. Just had a question regarding the rear diff.
I'm going to be doing some maintenance on my friends '06 pilot. It has almost 200,000 miles and she's NEVER changed the rear diff fluid. I know, yikes...
If i drain/fill it twice, will it cause it to fail faster since the fluid is still the factory fluid?
Or has any of you drove it around that long with the original fluid? Wasn't sure if i should just leave it alone or drain/fill twice. I'm planning on doing the trans 3x drain and fill as well. She's had it drained/filled a few times.
