Vibration can be so many things. As far as the leaking goes, you can remove the cover from the rear and re-seal. Vibration can be unbalanced tires, bad u-joints, bad rear, (hope not), and in my case it was my motor mounts were a little worn, and the slight drop in motor height caused my exhaust to vibrate off the cross member on the tranny, and I replaced everything and couldn't figure it out. It was crazy. Good luck, if any new info comes up on the vibration, please comment back, I am sure we can figure it out.

REPEATLY worn out carrier bearing on my 2001 GMC Sonoma extended cab ( 4.3 , 4speed auto 2wd) what could be the cause of this even after I've had it rebalanced?


  • If the bearing fails and seizes up, the rubber will be torn away from the bearing. The seized bearing can tear away the rubber mount that supports the outside of it allowing the bearing to rotate with the driveshaft. This allows the driveshaft to wobble up and down causing a vibration.
  • The rubber can also deteriorate due to age or contamination with oil. The driveshaft will operate at the wrong angle and vibration or noise will result. The vibration occurs most often during hard acceleration.
  • A worn center support bearing can cause a whining sound that varies with vehicle speed. The noise is constant in pitch, rather than changing or intermittent like U-joint noise.
  • If the truck has been raised , the alignment of the drive shaft will also change, A damaged driveshaft can exhibit a variety of symptoms. A clunk that is heard when the transmission is shifted into gear is the most obvious. You can also encounter unusual noise, roughness, or vibration.
    NOTE The engine, torque converter and driveshaft change in frequency as rpm changes. A rebuilt torque converter is often the cause of a vibration that is rpm-related.

    To help differentiate a potential drivetrain problem from other common sources of noise or vibration, it is important to note the speed and driving conditions at which the problem occurs. Unfortunately, it is often difficult to accurately pinpoint drivetrain problems with only a road test. Expand the undercar investigation by putting the vehicle up on the lift, where it is possible to get a good view of what is going on underneath.

    • Check the companion flange, carrier bearing, pinion shaft seal, and pinion bearing, transmission's extension housing seal and bushing, and the u-joints.
    • Check the driveshaft for runout, or the amount that a part wobbles up and down or side to side when it is in motion.

I have 2004 GMC Safari Van. I am hearing a loud rattling noise under the van. someone is telling me that it is a heat shield and others are telling me that it's my catalytic converter going. I do I find...


If you drive on gravel roads it may be gravel inside the shell,covering the converter this is the heat shield,or it may be loose and vibrating.Check fot any of the exhaust grounding out against the frameworks. If you have or can barrow a rubber mallot use it to beat on the converter pipe close to the converter ,you may find the noise related problem,look for loose hangers or clamps.

Klunking noise in rear end/drive train


Have the vehicle run on a lift with someone in the vehicle while someone else is under it listen for the racket diagnosting it this way should be a breeze, inspect the U Joints...the axle wheel bearings and the fluid in the rear if low refill.

05 camry SE 2.4L. while driving i feel a vibration under my feet.


Without feeling the vibration, it is hard to speculate, but, my experience here is this: you may have a bad rear wheel bearing. It is covered for 5 years/60,000 miles by Toyota

My vent will not change from defrost on my 2000 Safari


YOU HAVE A VACUUM LEAK AT A/C PLENUM. IT'S VACUUM CONTROLLED AND DEFAULT IS DEFROST, IF VACUUM LOSS IS EXPERIENCED THIS WILL HAPPEN. TRY TRACKING FOR A SMALL PLASTIC LINE THAT GOES INTO VEHICLE FROM UNDER WINDSHIELD FROM ENGINE COMPARTMENT. USUALLY BY ACCUMLATOR OR EVAP CASE. FIND A BREAK IN IT OR HEAR A HISS NOISE WHILE VEHICLE RUNNING THAT'S IT. REPAIR HOLE OR SUPPLY HOSE TO MANIFOLD

My safari all wheel drive 92 gets a vibration at around 85km. I have changed the universal jionts and the transfer case but it is still their?


If you feel it in the front end it is a very good possibility the it is the wheel bearings....if in the rear....the rear wheel bearings are questionable....OR you could tell me where you are feeling the vibration from.... ;)
