Regular AWD Mav's (non-Tremor), the PTU is always engaged, and the drive clutch (disconnect) is in the RDU.
Interesting article and how he mentioned the PTU is not enaged all the time......." driveshaft and gear sets that it’s attached to stop spinning". I find that pretty hard to believe that it engages while the driver doesn't feel it..... When "driveshaft and gears" are not spinning and then it all of a sudden spins to match the speed of the gear to be engaged, you'd think there would be a big thud/gear sound. Pretty cool they can make it silent or not enough for the driver to even hear or feel it.
No debate, they are different oils (and part no's) & different weights....the RDU is indeed straight 75w.
OK and there we have it- Now need to order SAE 75W - Ok to reuse drain plugs ?
Yep. I use just a dab of liquid gasket to insure a good seal without over-tightening.
Thx - Saw that as well.
The RDU takes 1.4 Quarts for a D/R ? Was hoping to only have a single quart to buy- Thx
No, both should be about half quart each. Very small capacities, thus the advantage of changing more often.
Correct. Doing my fluid swap today. Will be interesting to see what the fill level and condition of the oil is at 16K miles - RDU will be next week.
I did my rdu and had some clutch material there. But nothing mayor. I did it at 26k and i track thos truck before. Im kind of worried about my ptu because i did have a overheat code before..
