new svx owner with a strange popping noise
made a sweet trade for a 92 svx because the previous owner couldnt find the problem or was to broke to try. I suspect it to be in the rear dif (sounds like a pos unit thats not clutching properly) . Rear wheel bearings and cv axles are seemingly good. Do I have positive traction in this thing?

Could be the front diff.

Yes, the rear diff is limited-slip. What one sounds like going bad, I don't know. dcb |

not tires
I've put new tires on out of dire need(they were all mis matched and dangerous). the noise seems to be coming from the rear of the car when I back up or make any kind of turn. I can also feel it under the middle of the car when it happens. I did the LSD thing yesterday and some figure 8's but no luck. I know the person I got the car from and they probably drove on mismatched tires for a while, I hope thats not going to hurt me

If the previous owner ran it with miss-matched tires, it could have damaged the rear diff, the transfer clutches, and the front diff....
I've got a spare rear diff if you need it....and I'm not TOO far away....

Popping noise?
Doesn't a "popping noise sound", come from a worn shaft joint, half or tail shaft joint?

when a viscous coupling LSD goes bad (assuming gears arent chewed up), you usually loose the ability for the tow rear tires to turn at differnt speeds, it feels like torque bind. If the gears are shot you will get a howl that increases with volum with speed.
Popping noise from the middle of the car will be bad universals or bad carrier bearing. There are two driveshafts (half shafts) ubder the car delivering power to the rear wheels. They use good old fashioned U joints and are easy to diagnose. Just get under the car and shake everything in the x-y direction, there should be zero play. When do you hear this popping noise, and can you feel it in your seat or your feet. nipper |

when the noise happens
while I'm driving there is little or no noise. only when taking off, turning from a stop or backing up. U-joints and cv joints seem fine. I can feel it in the seat

If you feel it in the seat, it may be the transfer clutches binding....try installing the "FWD" fuse in the fuse box under the hood, and see if it goes away.
