I thought I may have had some problems when I first put it into 4wd when we got a big snow, but I kind of filed it away as a normal sound. Maybe not? It wasn't too bad but definitely noticeable.
4wd Noise while driving 07... not the clunk
so.......
Had to drive about 20 miles in a snowy mess yesterday, was going around 45mph or so. Threw it in 4, (07 tacoma, 5sd. 2.7 reg cab) and the whole time i was in 4wd the engine sounded a bit louder. Should it be louder? It drove fine, only has 10k on it. When 4 was off sounded normal. It wasn't absurdly loud, just a bit more than normal
i really think it may be the engine under more load. it didn't sound "bad" just louder. No radio or talking and i could hear it, the slightest yapping or radio etc and i wouldn't have heard it.
I'm probably just paranoid. i've owned so many beater jeeps and junkers that i freak and investigate all noises and still look under this 10k miles only tacoma for drips.
thx!!

normal...maybe on the new ones? 94...never did it, 98 t100...nope, 99 trd...nope. Couple of heeps....nope, no noise w/ them either.
I dont remember there being noise in 4wd when new, there's no sound difference between 2wd & 4hi for me or other Tacomas I've been in. Sure you weren't in 4lo? at higher speeds there is a slight gear whine.
It's normal, the engine has to strain more in 4wd and it makes the valve tap/injector pulse more noticeable. The 1GR-FE is a very loud engine.
never heard it before on anything else tho...
thx

do you have a 4 cylinder? it drives fine and it's not ridiculously loud, just noticable. Then again I've owned several jeeps, so i'm accustomed to listening for all kinds of s hit.
i guess i'm not going to sweat it....the regular cab 4x is loud as hell anyway, makes since if it's working harder, besides i'm fairly proactive w/ maint, oil changes etc and climb around alot under it, taking notice of things. Runs great. I'll ride this out.
bump for additional feedback
I have the V6, so take this at face value...
I have not noticed an increase in noise while driving, just the need for a little more throttle than otherwise would be necessary.
I have noticed that at 30 MPH when accelerating slowly, and when slowing (no brakes) down I get a harmonic noise while 4 wheel drive is engaged. It only happens from 30 - 32 MPH, and only with 4 wheel drive engaged. It's a subdued sound, but I can hear it when the music is off. Not sure if that sound is normal, but I haven't had any issues in the 10K that's on it.
