Question Axle Suspension Maintenance

My Newmar 5th Wheel, Tandem Dexter Axle with grease lubricated suspension bushings is 13 years old and I believe the shackle bolts should be removed and inspected for wear, but i'm reluctant to do this for fear that I won't have everything supported correctly and something will spring out of place that will prevent me from reinstalling the removed bolt. Most maintenace I do at home with the idea that I can always put it back together and take the unit in for help if the job doesn't go well. It will be hard to do that on this job if I can't tow the unit.

I would appreciate some guidance on how to perform this inspection as I think it's not too difficult if one goes about it right. I've sent a note requesting help from Dexter, but haven't received any response as yet. I've regreased the bushings about every 3000 miles, but have had to turn some of the bolts to get them to take grease. The consequence of one of these bolts failing has me worried.

with jack stands to support the frame after load is lifted off the axles, use a jack to find the no load position of the spring. remove the bolts. I replaced all my dry bolts and shackles in 30 minutes. Nothing is going to spring out of shape.

Thanks for the input Oldbeek. I had to think someone had done this procedure. I think I'll give it a try. The Dexter kit is about a $125 and I have a good place to work on it.
