1999 Volvo V70 AWD with awd issues

[rspi]

Ouch! Looks like I took a bad gamble. Should have taken the time to check this out before purchasing the shaft. If the beveled gear box is up front, it appears that it is damaged. My guess is, once the shaft starts to go bad and it's not dealt with, it will destroy the front gear box?

I have not checked the rear VC yet, will do that in an hour of two.

What will it take to fix the front beveled gear? If to much work, I'll probably look for another vehicle and flip this one as FWD.

Convert it to FWD or plan on making a lot of trips to visit your mother. If her cooking is good, keep it AWD.

I have a funny feeling that your VC is the culprit, but it's hard to say. Did you actually install the new drive shaft yet? If yes, what is happening when you try to move the car? Like I said before, if the VC is locked up, you can see the rear wheels jerking. If that's the case, don't try to move it any more and take the driveshaft out again.

There is a multi spline bushing which connects the bevel gear and the transmission. It is designed to break if things lock up back there. This is to prevent damage to the angle gear and other stuff. If it does break (basically the splines shear off) you end up with a FWD car. This is why I would be super careful testing things with the new driveshaft installed.

To inspect things further, you would have to take the bevel gear out and go from there.

At that mileage I'm not surprised you are looking at a wrecked AWD system to be honest. If you have no history on this, I would expect the worst

Also, keep in mind that even as a FWD car, the bevel gear needs to be fully functional. Do you have any leakage from the gear?

I just watched the video, wasn't able to before so never mind my comments. Catastrophic angle gear failure to be sure

The transfer case is at least very easy to change. The only thing kinda weird is the sleeve that goes between the transmission and the case. The sleeve fits into a double seal that keeps the transmission fluid from mixing with the gear lube in the case.

As I recall one of the bolts was a PITA to get a socket on but beyond that it was quite easy.

How is that any justification?
Any winter driver with half a brain will run quality winter tires with ANY vehicle.
( And AWD with good tires will whip a FWD with good tires any day! )
I don't understand your point...

Robert - Stick with it. There are BGs out there!
Or, yeah - you could always remove the BG entirely.
There are write ups dealing with it here (IIRC...)
and I'm pretty sure you'll find removal info at VS.

Good Luck!

So far the only thing I have done was disconnect the front of the shaft. I moved it a little to the right (passenger side) and tied it there with a coat hanger so that it could spin if it needed to. I took the car about 1.5 miles to have some new tires installed. From there I drove the car about 2 miles to where it sits now.

I'm going to remove the rest if the shaft as soon as I get up in a few hours. I guess I could "test" the VC by raising the rear of the car on jack stands and trying to twist the shaft before I pull it. If the wheels turn it works? I'm also guessing that I will see a lot of marks where the hanger is if the shaft was turning with the rear wheels

...while I drove the car it's short distance?

I did NOT drive more than 35 mph but it seemed to drive fine. My plan is to toss the new shaft in the back of the car and hit the road today to begin my 2,000 mile journey to Pittsburgh. I can visit several you pull junk yards on the way to check for a replacement beveled gear. Is it an issue driving the the beveked gear falling apart?

Huh? The back of the angle gearbox has fallen apart. Are you sure this needs to be serviceable to FWD this car? I can simply pull the angle gear and press on correct?

That BG is directly connected to the transmission output.
It's turning whenever the trans axles are. Park this car!
That BG output yoke has a nonexistent bearing.
BG needs to be repaired, replaced or removed.
