    Normal sound , especially when going downhill in lowest transmission gear while in 4 wheel drive low . The sound is the coolest to me .

    Yup that sound is normal. I think it sound cool, kinda like a big blower. The faster I go in 4lo the louder it gets.

    Well, depends on your transfer case, but prolly normal, yeah.

    My '205 is a fresh rebuild and makes a serious high pitch gear whine in low, especially in 4:1.

    If you have a 203 or 208/241, i.e. a chain-drive case, I'd be more worried if you heard whirrrr-chunk-whirrr-clunk, which would indicate the chain slopping around or doing some other evil thing.
