Hi guys, I have another towing update and figured I'd get your thoughts on the results.
I towed the camper again but this time I went up highway 285 in Colorado. It's still steep but not nearly as long and drawn out as i-70 here. It was a bout a 2hr drive and ended up stopping around 10,000ft.
Result:
I experienced the whine again but it was quieter this time, and didn't last as long. After I got to less grade/more flats with hills, it generally goes away slowly.
On the way home last night, I was heading from 10,000ft elevation down to about 5,000ft. I payed close attention to the temp gauge for the tranny and it never got above 180-190. The outside temp ranged from 45 degress to a max of about 65 as I got down in elevation, however I did start to hear the same "whine" sound coming alive after I was using the gears to hold down a 5-7% grade.
Given that the transmission wasn't hot, or wasn't nearly as hot as previous runs, I'm now wondering if it's my transfer case making the noise and not necessarily the transmission?
I generally start to notice the whining noise when I touch the brakes, the noise only comes from the front and it seems that it's due to the braking stopping the wheels....which are connected in the AWD to the case...then the tranny.
Temp wise it doesn't seem like it was nearly as hard on the transmission to use it to brake down the pass, but I'm sure it was equally as hard on the transfer case/diff as going up hill.
Any thoughts or speculation/recommendations?
