    You may need new air lines also.The fittings on the steel tubes connecting the bags almost always leak when reused.

    If replacing 1, replace all, its more expensive, more work, but when one fails, the rest are on their way out too

    I agree but it’s harvest time and I’m harvesting my own crops and hauling them. In a days time, if I’m lucky(sarcasm), I’ll wrench on two combines, two headers, tractors, augers, grain bins and the other trucks. I’ve got a list of stuff to accomplish before harvesting starts today. 1 air bag to replace, is about 4th on the list.

    A pair of vise gripes in the appropriate spot will keep you rolling.

    Just pinch off the air supply going to the blown out bag,one of the plastic lines,then duct tape to keep the vise grip from coming off.We do it all the time hauling gravel,best to not load it quite as heavy as you normally would.

    They make quick connect caps now. 20 for $15 on Amazon. Great for brake cans and air bags that fail. The days of bend and pinch with vice grips are over. I work parts at a TA Stop. Just found this discussion group. Air Bags change out quick when you can find one. We have some still on back order 3 months ago. there are some weeks we will replace over 30 airbags.
