Re:driver side drive tires spin when taking off from a stop

I have a 2004 Monaco Dynasty with a 400 cummins and allison 3000 6 speed. Today when i took off from a stop the driver side drive tires would spin if i gave it to much throttle. This is on dry level pavement. The coach has a tag axle also if that makes any difference.

Could be a air suspension issue with drive axle or you did not let air brake compresssor build pressure past 60 psi to release all air brakes.

thanks for the reply. i was kinda thinking the same thing about air supply to the axle. the system was fully charged at 125 lbs however.

Well when was the last time you had the brakes, wheel bearings and wheel seals looked at. The brake slack adjusters might need adjusting or a s cam is stuck on the pass side of drive axle. Is the back side of brakes (axle side) wet aka not completely dry. If so this can cause the brake pad to stick to the drum on the one side as well. Let me know what you find

Oh do you have individual push switches for air brakes and air suspension?

Check the level valves make sure your ride height actuators are not broken and properly adjusted. I'm leaning towards the tag axle is carrying all the weight.
