Vibration and noise from front end Toyota 2002.

Possible have a caliber not retracting all the way and the brake shoe is slightly scrubbing the rotor. Don't overlook the possibility of wheel bearings or CV joints.

sounds like front wheel bearings. does the noise change, get loader when making turns?

Hello, I see you may a lot of changes and replaced a lot of parts. We leased an Explorer the same Year as yours. In our case there was a slight noise as well as vibration. The problem was the Front Hub bearings, They were bad at 18000 miles.

There are a few things I want to suggest. The spinning of the wheels on the lift will not load the bearings. A Dyno table can get everything turning with a load on it. As your vehicle is a 4x4, most Dyno's were 2 wheelers. You would have to call to find one for a 4x4.

Next, if the new Hubs do not help, have a look at the rotors. They are also balanced. You can spin balance the Wheel and rotor as a unit with a floor motor. It's not the best way to Balance because tire rotation or even shifting the Wheel on the lugs will UNbalance it. But this method CAN pinpoint a problem if a Balanced tire does not spin true when bolted to the vehicle. You will know the Rotor is off-balance and which axle is causing the problem.

Would be interested to see a Post of what you found.

Vibration at 40 mph hard to diagonisis without looking at front end. Could be wheels need balancing, new wheels and rims. Loose or worn suspension items.
Bring vehicle into a tire and alignment shop. Most Sears auto center have them.
With regards to rubbing noise again hard to diagonisis without looking at the affected tire, probably a splash shield hitting the tire in reverse.
Alignment shop will find the problem.

Jack up the front end and put stands under it and block rear wheels. Look at axle boots and see if they are cracked. Try turning wheel back and forth sharply and see if you can hear any clicking. Problem could be outer axle joints. If the boots are cracked or you hear a clicking noise you will have to replace the axle. The axle and boot come as a complete unit. Please let me know what you find out.

That sounds like a left front wheel bearing gone bad My friend.. turning right transfers weight to the left side and it probably has a roar similar to a turbo fan jet.. Try it and lemmie know.. thank you

Sounds like front differential or front drive axle issues. Check the front differential gear oil then take er' to the dealership before you end up spending a bunch of $. Most people change their oil frequently in the engine but forget about flushing the transmission fluid and changing oil in the front and rear differentials. I have three Ford 4X4s. Two which really get used hard. The 93 has 311K miles and still runs excellent. Trans and differentials get a fluid change every 25K miles and moble one synthetic engine oil changes every 5k miles.

hello have u rotated the tires front to rear then drive and see if u still have the noise and vibration if drive yes while driving slowely turn the steering wheel left to right just a small amount if the noise changes its probably a front wheel bearing if that doesn.t help drive the truck till you get the vibration then let up on the gas pedal does the noise go away if so you might have a bad u_joint but do the tires first how many miles???????

100 series landcruiser auto 98 model 226000 km
whine from front end after 25 kmh no noise when backing off

Check the U-joints and axle baerings. But its most likely because the truck is in four wheel drive.
