AWD question
I dont know anything about our awd system. This morning me and the wife were out in the snow. I have pretty much bald all season tires on the svx. Amazingly it comes out of my drive way and up my huge hill and it is slick. My question is, I had my wife to stomp it while I watched in the walmart parking lot and the two drivers side wheels spin but only the front passengers side spins. Does anyone know if all 4 are supposed to spin. We dont it a couple of times and the same results, the back passenger side wouldnt spin. Thanks.

Re: AWD question
It should be the other way around: One in the front should spin while both in the back should spin.
The front differential is open, so the one with the least resistance is going to spin. The rear differential is LSD, so after a little bit of one spinning, they both should start to spin. Also, if you have nearly bald all-season tires I wouldn't expect your car to be going much of anywhere. AWD is good, but bad tires make AWD worthless. You might as well be driving a FWD car with bald tires.

Re: AWD question
Actually it went really good. I dont know whey but both front and the drivers side rear spins and that it. Anyone else know of anything it could be or if it is normal.

these are not mechanical limited slip diffs. the oil used might be gone or bad. I think they also use clutch disks and if they are toasted that might do it. |

Re: AWD question
It's hard to say if I take what you're saying correctly...
Basically, Open differential means that the power goes to whatever wheel has the least restriction (traction) on it. -So if one wheel is on ice, and the other on dry pavement, only the tire that is on the ice will get traction LSD which stands for limited slip differential should apply power to the wheel that has the most traction and if a wheel is slipping, will transfer the power away from that wheel to the other. So it is possible for one of the rear tires to spin depending on how slippery the surface is. -So, again, one wheel on ice and the other on dry pavement, it will probably put a little bit of power to the wheel on ice before transferring all power to the wheel on dry pavement. So, the tire on ice could get enough power to spin it, and then because its on ice, there is no traction to stop it from spinning giving the allusion that it is spinning. So disregard most of my previous post as I was not thinking clearly |

Re: AWD question
Sorry I'm not getting this guys. So, does our rearend have fluid that truns the axles? How do you replace the fluid? I am usually very mechanically inclined, I just dont know squat about this awd system. I have a thumping coming from the back to which kind of sounds like that wheel may be trying to kick in. How do I check the fluid level. Sorry guys, any help is appreciated.

The LSD is sealed for life, needs no servicing! 2) There are two 1/2" drive plugs on the back of the rear differential. Unscrew them and drain it. 3) When you refill it you use the top hole. When the oil spills out of it while filling it, its full.
