[QUOTE="Badgertits, post: 1833584, member: 31322"] Not sure whether this is “normal” & I never noticed it until now, but been raining heavy last few days & had left truck in 4a, was nice out this afternoon & had all the windows down going down highway & realized truck was still in 4a so I switched it to 2wd & immediately noticed was quieter overall. Put it back in 4a & sound returns - only under throttle. I guess it could be a bad bearing noise but would still hear that in 2wd, it’s a whirring/whooshing air type sound, not a grinding whining typical mechanical issue sound Literally opposite of what an IWE issue sounds like- it comes on in 4a under throttle goes away in 2, iwe seems like it’d be the opposite I know the front hubs are engaging as I can feel the front biting when it was wet out & did a little off-roading last week as well. Any ideas? On the passenger side I noticed a little bit of weeping at the axle seal - which I know is common- but my truck showed this from day 1 & it was initially a little wet when I first got I figured maybe overfilled and/or weeping stopped on it’s own- you. Can tell from this pic, certainly doesn’t look like it was weeping anytime recently, also I heard this from the driver side (Altho may also make it on passenger side but can’t confirm yet) Any ideas? Would post a vid but not sure how [/QUOTE]
