I have a 2006 4runner and it has a rather loud whine coming from the rear end, is it the wheel bearings or does the diff need work ie bearings?

My 2002 Sequoia had that ***** whine too.
It ended up being rear wheel bearings.

Not to rule out ring and pinion gears in the rear end, I hope it ends up just being the bearings for you.

Rear whining when I let off the gas pedal. just had the rear diff pinion seal replaced. what could the whining be ?

Pinion gear needs to be adjusted OR bad bearings. Was this a USED unit? Check YouTube for a video titled "How to set up a pinion gear in a differential".

Whining noise rear end

if the noise is occurring on acceleration it will be the rear pinion bearing
if it is on deceleration it will be the front pinion bearing
if it comes and goes s you drive normally it is the incorrect mesh between the crown wheel and pinion and indicates worn carrier side bearings allowing the mesh of the crown wheel and pinion to vary
check for correct oil in the diff and check magnet on drain plug for metal bits

What size socket is needed to remove rear pinion nut on 1997 jeep grand Cherokee limited with a5.2 v8

the rear axle front pinion DANA 44 or AMC?
the answer is not simple , why not read the FSM and unstand it all.
  1. On 1990-98 models, set bearing preload as follows:
    1. The required pinion gear bearing preload torque is 1/2 ft. lbs. over the noted release torque as measured above.
    2. Rotate the pinion gear three or four times with a torque wrench attached to the yoke nut. Measure the amount of torque necessary to rotate the pinion.
    3. Using a holding tool, tighten the yoke nut in small increments and remeasure until the specified torque is obtained.

see diff chapters. its non trivial.

Knowledge base

Wow this a touchy. There are several options to look into. Don't be mistaken with always the most obvious. Sometimes the problems occur right in front of our eyes and we still cant find it. A option i'm thinking is, and i'm not over ruling that what you mentioned, but is to jack up the vehicle with all wheels in the air. Use safety when doing this. Fire up and put her into gear try going through all the gears. Rev only to about 2000 rpm. Get out and try to listen all around the vehicle. Listen to wheel bearings, actually after a drive you place your hand on the wheel hub and feel for high temperature. Wheel bearings get hot if they are on the way out. Listen for grinding near the diff sections, Listen in the engine compartment. Use a long steel rod or something place the one end on the gearbox near the engine and place your ear on the other side. My guess is your crown wheel and pinion on the diff is on the way out. Yet difficult to establish, but when you go through all the gears maybe even look at gearbox syncs. A good way to establish if the pinion of diffs are the culprit is to get under the vehicle when on the ground, engine switched off, and in neutral handbrake down, is to feel propshaft play on the pinion. It shouldnt rotate more than 2mm either way.

Is it common for the diff to whine slightly on a Jeep Cherokee with 89000 miles on the clock. Thanks

Not a common thing but yes they do give out.Get the fluid levels checked 1st and these diffs need friction modifier in the oil(limited-slip diff).Just make sure 1st it's not a rear wheel bearing.If you are sure it's the diff,they are quite easy to change.It's the pinion gear that usually goes.Hope this helps

Axcel rear noisy

Your carrier bearings and possibly the pinion bearings are the source if the noise is a low pitched grumble or gravelly noise that starts just about 20 mph and up. If it is louder when quickly changing lanes to the left, it is probably the right wheel bearing, and if it is louder when changing lanes to the right, it is the left wheel bearing. If it is a whine that is really annoying at 45-65 mph, your ring and pinion are probably worn beyond their design specification limit. If your U-joints are OK, but you can hear a loud clunk from the rear when you get on and off the throttle, you definitely have play in your ring and pinion. Have the cover removed and you can sheck this easily. I have worked on several Jeep Grand Cherokee differentials, and the ring an pinion has needed replacing on them all. A few had bad bearings, too. You should probably replace the bearings and the ring and pinion, because the labor is nearly the same and the parts are just a bit more. If you look through the forums on the www you will find many people that replaced the bearings to fix the grumble, only to finish the job and find out they also have the whine.
