I picked up the additive and put it in last night, hope to run the car on jack stands possibly tonight & see what happens! I will let you know if that is the CURE! Really thanks everyone FABO has been a Great help!
Jack stands won't tell you anything as you will have to drive it a little and turn a few corners to find out anything.
The thing about an 8.75 is that you have to pull the axles and driveline and then take the carrier out to visually verify what's in there.
But it would also be nice to know for sure.
