And when Ive had this issue it's always been a front axle - usually the drivers side actually. BUt it only happened to me on 2 95-99 Subaru's.

Re-read your original post. 239K on the car! If that's the original axle, that's the problem. My experience has always been with the manual transmission so I don't know if the torque convertor might be an issue. I also have always had this issue on the drivers side; probably since that's right above the catalytic convertor so the boot fails there more often than the passenger side.

What did he mean by a "little warp" on the front axle? If it's related to the DOJ then the axle is your issue.
ok i have had the tire rotated balanced and checked for splits all that is ok. The mechanic did say that there was a little warp on the driver side front axle but he said that should not cause this bad of a vibration ....... now that being said i just remembered back in may we pulled a code from the car ( check engine light came on ) and it was for a torque converter locking up could all this be related ?????

CVJ is the outer joint; inner joint is DOJ.
Could be a cv axle on it's way out. Check to see if either inner boots are torn.

I know this, I just said the axle in general, and then specified the inner.
I agree if it's the original axle, it's probably the cause. They can look just fine, and "feel" just fine when you grab and try to move it by hand, but can cause vibration when driving. Just because it looks ok, doesn't mean it is.

Never seen a BAD subaru torque converter, much less one that causes vibration. Sounds like you need to find a more subaru specific mechanic.

That would vibrate with engine speed, not wheel speed, and would not change when taking your foot off the gas.
This is drivetrain related. Bad U joint, bad inner CV axle, bad carrier bearing or carrier bushing.

I've replaced quite a few aftermarket axles with rebooted OEM used axles and had good results too as long as they weren't making noise. That is also a cheaper option. Boot kits are fairly inexpensive and not too terrible to do. Just be ready for a greasy mess:brow:

Is it a vibration, or a knocking?
Were the wheel bearings checked?
When you speed up does it speed up with the speed of the wheels or about 4 times as fast?
The axle could be shot and seem tight when the car is up on the lift.
Make sure it gets checked with the weight on the wheels.
