It's easy to unjustly persecute someone with a blind response, and an emotional response is dangerously quick.

Yes it does wobble

The subtext is true as an adult who has a job, a family should also have something called life insurance! It is also true that if you kill a kid you can expect to pay 3x more on average. Juries like kids plus they don't have a job and when taking expected income into account Johnny is gonna be a Wal-mart heir and the Dallas QB

I'm not the one who got emotional as if you knew me you know I really don't. Selfish people though .

off topic can we please get back to the topic guys, i can really use some help

the car does wobble, and sounds almosy like something is stipped... DIFF? Driveshaft? I dont think it can be the tranny, can it? cuz it goes in reverse fine, and still moves forward sometimes

As I have almost the same problem I am curious weather it can be front diff. as this sound occuring for 15k KMs in my case. Personaly do not belive that front diff can stand this for so long, checking fluid regularly and it is always on the full mark. As I am still more and more involved in this it is very hard to find from cockpit from where it goes. I was convinced it goes from the front but now I can say that maybe from prop. shaft area (rear bearings on prop.shaft/rear dif?). In my case it would be easy to test it just inserting fuse to disable rear. This should tell me weather it is on front or rear part of car. If no sound occures it has probably someting to do with prop.shaft, if there is no change, it could point to front diff (pray not to be), axle, cv joints and stuff like that. I will have chance to test it thoroughly with my mechanic next week, so I will be back with conclusion.

see that sucks, cuz when i put my fuse in, it makes it RWD hahah wtf this car is weird!

[Nobody]

your damn american models. We in Europe have via inserting fuse only FWD, fuse disables fransfer to rear wheels. I am just thinking to convince myself it is not front diff as this would be very expensive scenario. At my case it occures only on a sharp turns under full/half gas or on stright on full gas. If it is front diff, I asume, it occures all the time where diff work is needed, does not mind on low or high speed the work diff has to do is let's say equal. But...
I have AWD car which means that (in SVX case) on shrap turns on low speed the power has to (or is) transfered via tranny("center diff") to the rear and than noise is up. If I am going faster I can feel in sharp curve moving the power from front wheels to rear (very exciting feeling) with no noise (prop. shaft is working in high speed). On stright it does not occure until I fully press gas pedal (I do not like to burn my tranny so not doing that very often). This is the same case, 90% of power on front wheels and when tranny recognize that it is supposed to move power to rear wheels to keep the traction, noise occures. So conclusin for me is to focuse on prop. shaft. and rear diff connection (see here). There is quite few parts that could cause this. I had recently problem with bearing in my tranfer case so this will be the first thing I will start with. Comments welcomed.

92AWDSVX,
Can you jack the car off of the ground, and safely support it with four jackstands?
With all four wheels off the ground, the engine off, and the automatic transmission in park, you should be able to turn (spin) the front tires.
When you do, look under the car and see if the other side turns the opposite direction.
It should, and it should be smooth.
This will let you see if the side gears and planetaries in the front diff are (mostly) OK.
If the wheels turn smoothly, and freely its time to check out the front ring and pinion gears.
This SHOULD BE DONE BY A COMPETANT MECHANIC, as it can be dangerous!
If you start the car, put it in gear, let off the brakes, the front wheel/wheels should spin.
KEEP AWAY FROM THE SPINNING TIRES!
Does it now make a clunking/banging noise?
Do not get under the car with it running.
Have someone in the drivers seat while it is running, so that they can shut off the car engine.
Shut off the car and report back to us.

Like someone else said, drain the front differential and look for metalic debris, or metal chunks of teeth!
If your car is rear wheel drive when you install the FWD fuse, you have the only one in North America.
NOTE; Unless you have a JDM, or European transmission.
A correct SVX awd automatic can spin the rear wheels when up in the air as described, with the fuse in, (and it should spin with the fuse out) with the engine running and the car in gear, but it is because of friction in the F/R clutch pack, or a bad solenoin C.
What is probibly hapening is only one of the front wheels is spinning under power, and you can't see it.
Have someone else check this out with you.
Only one wheel needs to spin when the car is up in the air.

Petr,
A correction. For JDM and European models putting the fuse in locks the centre differential - it does not disable drive to the read wheels.

So I guess now BOTH of your diffs are toast.

I'm not the one who got emotional as if you knew me you know I really don't. Selfish people though .

I suppose turnabout on the emotional card is fair play. It's kind of a knee-jerk reaction. I always feel offended when somebody implies that I'm less important [or valuable] than someone so young that there's no possible way they could have already redeemed the expense of being raised to adulthood. I don't want to come off as completely heartless and cold, but children are a dime a dozen. Anybody can make one. There's a surplus of them actually. Making a child is a lesser miracle than successfully raising one to an adult. I think both parents and children would agree on that point. Sometimes one party more than the other.

I'm glad you understand why a view that children are more valuable that adults might rub me the wrong way. I'd probably feel differently if I were just a wee lad.

You're right, we're off topic, but I think we're pretty much all out of help. Have you jacked up the car yet? Have you drain the differential fluid and looked inside? Have you checked the lug nuts? We've told you how to find the broken part. You need to go do that now. When you find it, let us know and we can help again.

I think you are a bit confused, on the AWD operation Petr.

You have a VTD that has power to all the wheels all the time. 36% to the front and 64% to the rear wheels. In cornering the torque to the front wheels is increased, maybe 42% front, 58% rear. Inserting the fuse, locks the Limited Slip clutch to make it 50% front,50% rear. You can't turn the rear wheel drive off, like inserting the fuse, does in the US transfer AWD.

The front diff in the VTD AWD is not subjected to the same loads as the diff in the US AWD. The US version can lose the drive to the rear wheels, if the transfer clutch doesn't work. This leaves only the front drive that can be subjected to high impact torque loads, as the front wheels spin. This can't happen in the VTD version as it can't lose the rear drive. So it doesn't suffer the same high impact loading.

I think in your case, the problem would have to be in a Constant Velocity joint, either in the front or rear axle or on the center bearing in the prop shaft. Lift the car on a hoist, run it in D, turn the steering side to side, to see if it is there. I doubt it is in either diff.

Thanx Harvey I am probaly lost :-) but like to learn...
This week I will let my mechanic to check it so will know what it is in couple of days. As for me it is not center bearing on prop shaft as I once drove old Outback with this problem. It was clasic failed bearing sound beeing noisy at higher speed, so noisy all the time (terrible sound). As for me it is someting on front wheel (joint) or bearing on the end of prop.shaft/rear diff or both of them:-). I will stop guessing and let you know what it is after check.
