Front bearing making different than normal noise has front wheel drive

This can be caused by several different things, such as: A bad axle shaft, the differential or transaxle bearings. The ring and pinion drive, wheel bearings etc. Any one of these will cause shaking and noise on deceleration. Check transaxle fluid level, raise vehicle front end and check for slop in the wheel bearings and check for noise while spinning the tire. The wheel bearings will often make noise when lugging down as you put it due to the weight shift to the front wheels. This also applies to the axle shafts and CV joints and the differential.

It should have been thoroughly checked. Noises like these on four wheel drives could several different things. A bearing, CV axle, or the differential, or bearings in the differential. A wheel bearing will make different sounds when making a turn. A CV axle is a constant sound. Differential bearings can come and go, depending on if it is a bearing for the axle or a pinion bearing. Axle side bearings usually make a constant noise. The differential can also come and go. Depends on acceleration or slowing down. All these sounds are also with a vibration. Slight to harsh.

It could be the hub bearing. Once the car is on the ground, the weight puts more load on the wheels. See if the noise changes when driving while turning the steering wheel

WHEEL BEARING USUALLY STARTS MAKING A ROARING TYPE NOISE WHICH USUALLY GETS LOUDER THE FASTER YOU DRIVE, SOMETIMES THEY WILL BE LOOSE , TO CHECK JACK UP THAT WHEEL AND GRAB TOP AND BOTTOM OF TIRE AND SHAKE, IF THERE IS MOVEMENT, TRY TO GET SOMEONE TO ROCK TIRE FOR YPU AND WATCH WHERE AXLE GOES INTO CENTER OF BEARING AND SEE IF AXLE IS MOVING WITH TIRE MOVEMENT AND SPINDLE REMAINS STATIONARY, THEN IT IS BAD BEARING, OR SOMETIMES THERE WILL BE NO MOVEMENT, THEN BLOCK REAR WHEELS AND RUN CAR WITH THAT WHEEL IN AIR AND SEE IF YOU HEAR NOISE, GOOD LUCK.

I believe the bearings in the front wheel are about to come to the end.
Have it checked in a garage.... NOW! otherwise you will be driving on 3 wheels... sooon.
Iceman.

well did the noise start after the tires were rotated?could be choppy tires,,,if not ,i strongly think it sounds like a bad wheel bearing,,,,if you drive and while its making the noise turn left and right quick and see if the noise gets louder and which way turning makes it louder,,if you turn leftand it gets louder its usually the right wheels bearing as you are putting load on it, if it makes the noise louder while turning right its the left wheel bearing,,,got it

We have the same problem at our shop. We haven't rebuilt the front differential yet. We tried 3 different shafts on 2 different Jeeps and the noise is on both just the same. By greasing the front driveshaft cv joint, we got he noise to quiet some, but it is still way to loud. With the driveshaft out, the noise is gone. We are about to buy a new shaft from the dealer for $600. There are some service bulletins about some noisy driveshafts.

That's a hub bearing. Replace the one that's doing it. I'm assuming this 'roar' is coming from the front, NOT the rear.

That is the bearings going bad on it.

Check wheel bering for play if there is no play , it doesn't mean that bearing is NOT bad its can still be dry and would be making that grinding sound you described Also check axle and see if boot is broken. That may be your problem also make sure that rotors are not gouged/scraped up and pads are good.Contact if you need more help and thanks for using FIX YA
