I bought a used 2004 Rumble Bee about 3 years ago. I have been running it at the local drag strip for awhile now. The whole time I have been the burnouts, only the right rear wheel has been spinning, so I just asumed that it did not have LSD untlil last night. I made 10 passes and on the sixth burnout both tires were spinning. Does anyone know why this would happen?

 

The stock LSD is very slack, it will rarely lock up both wheels. And it will commonly fail, requiring an expensive repair.

 

bad clutches or fluid. Have you ever had it apart and checked either?

 

Sounds like time for a better posi. Thanks

 

No I haven't. Might be time though, just turned 30,000. Thanks

 

LSD was outlawed in the 60's

I don't know if your glovebox sticker will show the "anti-spin" option or not.
Either way, if you have it, it isn't working. Mine always spins both tires.

 

Mine always would spin both tires also. Although I was never abusing or rough with it, I would get out in soft dirt every so often and check it. I only upgraded mine because I got a deal on a whole new setup.

 

time to replace is with an auburn
