Thread: Whining noise at certain speed

  1. #1

    Default Whining noise at certain speed

    2000 Limited, Selectrac, 4.7 V8, 85k miles.

    At a certain fairly high steady speed, I get a whining noise. Starts at about 55, loudest at 60 and diminishes to 65 when it goes away.

    If I'm accelerating, no noise. It only occurs if at steady speed or on decel. Only happens in that 10 mph window. Quiet at 50 and at 70.

    Noise seems to be coming from under the tranny or xfer case area. Definitely not the rear axle.

    Anyone know what's up? I've never had Selectrac before, understand it's rare with V8 limited; could it be the transfer case? I can't tell exactly where it's coming from; could be trans.

    Don't think it's the front axle, I drive in 2wd on the highway (and 99% of the time anyway).

    Don't want to damage anything.

    Please don't tell me to just drive below 55 and above 65. Trying to figure what's wrong.

    Thanks in advance.

    Should have mentioned that. Flushed and changed fluids/lubes in both axles, auto tranny and transfer case about a year/8,000 mi ago. The old flluid/lube looked fine.

    well i have a 93 zj and it also has the whine(for now) and its the front diff. even if you drive in 2wd the axles and gears are still turning. There just not being driven. Sounds just like my problem. Except that you have 85k and mine has 293,000 miles. But weird and unfortunate things do happen.

    Could it be a u-joint in front driveshaft?

    I bad U joint would make vibrations rather than a whine. But it wont hurt to check it all.

    I had a similar problem at the same speeds until they changed one of the wheelbearings (front) and it was gone. Maybe something to look at?

    '99 4.0 Laredo with select-trac, 136,000 miles. Great car.

    Good luck.

    Could also be the crown & pinion. Lots of vehicles get that from these. If it really annoys you that much look for another gear set with the same ratio and try them. We did that for my Challengers resto, lots of them whine, the one I have now doesn't, it's boxed as Yukon but we all know they're basically cut at the same place. My 0.02c

    thanks...

    Anyone know how to find a whine?

    First thought is to have a garage put it on a lift and run it at 60 mph. Use a stethescope. Wouldn't be a load on the components, but it might still whine.

    i had a similar problem on my 2000 v8 limited. i could usually only hear it when the windows were down at any steady speed above 30mph and it ended up being the front left CV joint. take a look there might be some grease slinging out. it happened a couple of years ago so i could be thinking of something else (you know how "the jeep thing" goes) but it doesn't hut taking a look.

    2004 Overland it was the pinion bearing in the transfer case. Then they changed the rear gears and it seems okay. There is a tightness and slight hum at 50 mph then it goes away...from the front end but I had the same thing on all for GC's i have owned.

    Seems Chrysler had a problem with preload on the pinion bearing. They don't put enough on it when assembled and when it breaks in it has too much clearance and does its whiney thing. I have had many with the same noise.
    My 2000 Limited makes it too. There is a TSB on it somewhere I remember reading it. Doesn't seem to bother it much cause I have ran them thousands of miles and they never get any worse.

    Good Luck...

    Maybe not the u-joint, but look and see if the boot over the cv has failed (you'll have a spray of grease on the underside of the car). Whe my front drive shaft went, it produced a whine very similar to what my front diff did when it was low on fluid...

    I've replaced the front dirve shaft today. Not thing changed. The sound still there. The wheel bearing also checked today, looks at great condition. Any suggestion??

    I know I had a whine for long time, which seemed to be especially noticeable during deceleration. I had one of my diffs rebuilt, or at least the pinion bearings replaced, but can't really remember which diff. From what I gathered, it was a pretty common problem. Other than the whine, I had no other symptoms. I had an extended warranty that covered the repair.
