I like to do one side at a time. Sometimes it hard to beat the spring saddle off of the spring, so replacing the saddle with the spring is alot easier. You can use an air hammer with a chisel end to clean/break out all the dirt in the buckets. The buckets can fill up with crap so the bottom pad doesn't fit correctly. You can use a small car floor jack to lift the buckets into position, the buckets are heavy. You can use a port a power or a come along to push or pull the axles back into place when you install the buckets. Wire wheel the shit out of the trunnion bar and then grease the shit out of it so the spring pack slides back on smooth. Make sure everything is supported as you go along.

Hopefully some of this helps. Thank you fore your response we had to cut all the bolts out 3/4 impact not doing job but we have it all apart. Ready to install one side. learned that you have to sapport the buckets on the spring before cutting the last bolt. lots of tennsion on spring. LOL. Will do other side different. We will be back if we have questions. Thank You.

Really alot of money but you get good results with warranty at a Mack dealer. Think about this you finally get everything stripped down and find the trunnion shaft requires replacing, then what?

Unless you are experianced on what to look for and do it yourself you going to do it all over again next year.

How do you no if u got to replace the trunnion what do u look for.

If we got to replace it I think we are screwed we welded a pintel hook plate on the back last year if u got to take it out of the rear of the frame.

Normally when a trunnion needs replaced you will see cracks in the center section or if the bar is completely shot. If the saddle bushing is completely gone and the steel saddle has been riding on the steel bar for along period of time the bar can be damaged. All the trunnions that I've replaced had cracked center sections. If the bar looks ok its ok. Its like anything else, if the bar is bad you'll know its bad. I've never had or seen a rear suspension rebush or spring replacement come back and bite us is the ass. Tear it down and slide the new bushing or saddle with bushing on the bar and see how it fits. Keep it simple.

If it needed a trunnion replacement everything would just get removed or cut off. The pintel hook wouldnt stop anything. There is also a trunnion that has spacers that can be installed without moving anything. You just put it up and add the spacers, its seems kinda cheap.
