Ok, I'm lost here. Most recommendations I've seen say we can go 30,000 miles between PTU fluid changes. Are people changing fluid at 30,000 or 10,000 in the OEM PTU? Thanks

Check your owners manual. Mine says SAE 80w-90 for RDU and SAE 75w-140 for PTU

That tube you used is a little bigger than what I had on-hand. Next time I'll give it a try. I used AMSOL in my last PTU change and I've got Motorcraft ready for the next. I was late on the RDU and wanted to get it done because there are mentions of RDU failure/replacements here and on youtube. The fluid I took out was really bad. Another thing I noticed is the rust and pitting on the exhaust pipe from my cat on back to the muffler. Isn't this supposed to be stainless? Looks like it will fail soon and I'll need a new pipe and muffler.

Not sure what diameter of silicone tube you're using, the only tube I could get to fit was 1/4 inch. The RDU is packed tight with gears and a big one right behind the fill plug opening. It took me three stores to find SAE 80w-90. Finally settled on Lucas SAE 80w-90 heavy duty gear oil. Thanks

Ok, that's what I was looking for. Hoping the fluid change will prevent a RDU failure. Thanks

Is there a drain plug on the 2018 RDU? My 2018 PTU has a drain plug. Did they put a drain plug on the RDU in 2018? Videos on the subject show a pump out by hand from the fill plug and not getting all the old fluid out. Thanks

Is this fake?

No, I didn't upgrade the battery just went with the recommended one from the Interstate website for my 2018 Edge 3.5L. Thanks. Just wanted to be sure.

I put in the recommended battery from Interstate. Besides resetting the BMS is there any other changes I need to make?

Perfect. So the new tire is on the same rear axle as a tire that's just been riding around not used for much braking or acceleration. It's just like a new tire. Those tires will be moved to the front in the rotation. Thanks

2018 Edge Titanium 3.5L AWD

Pretty sure my rear axle doesn't disengage at cruise speeds. That feature was added to 2020 and later AWD models. Starting tomorrow I'll be rotating my tires twice a year with each oil change.

Ok, after every oil change. Thanks

Yea, saw that. But when? After how many miles?
