How often do I need to change the differential and axle fluids? I changed them @ 25 K miles 1 year ago, but I tow my 5er every now and then.

How often should I have the tranny flushed? I had a SC III 1 year ago and have put on @ 25 K miles too. Every other oil change I change the tranny filter and the fluid still smells good and looks cherry red.


Thanks

Diff fluids depends on how much you tow. You can check the fluid and see if it looks dirty or if it still looks new. Mine after 20K looked new (after the first change at around 1k miles) but I don't tow.

If you had synthetic put in the tranny and you change you filter like you said you should be good for 50K miles.

I put synthetic into the diff and axles but not the tranny. Thanks

I'd change the tranny fluid to synthetic otherwise I'd flush it and replace it with dino and flush it every 20K-25K miles. That's just what I'd do with mine.

Thanks
