Need some suggestions, I have a single axle trailer with a 20 ft center console, I need to change the springs, I have all the needed hardware already. Unloading the boat is not a wasy option, I would like some suggestions on how to do it safely. I wish I could do one side at a time, but the pressure on the opposite wheel would let the axle move dangerously. I have already replaced the rest of the trailer hardware with stainless, springs are the last to complete.

I have done that on a tamden axle. What i did was raise it up untill the wheels are almost off the ground and put 4 jack stands in front and behind the springs under the trailer frame with the wheels barely touching the ground. Be sure you are level and everything comes off and goes back real easy. I lowered the front of the trailer as low as the tongne jack will go and put the stands in the back then raise the jack untill the wheels are almost off the ground and put stands in front of the wheels. Hope this works for you john

Lift and block up the trailer itself taking most of the weight off the tires and springs. That way there will be no load shift when you use this on it....

I've changed my springs twice over the past 9 seasons (the ones on it when I bought the trailer were bad) and I wouldn't advise doing it with the boat on the trailer. With all the banging and jacking you have to do to get it all to line up, it's much safer if you can do it with the boat off...
Either way, get a can of Kroil or PB Blaster and spray the nuts holding on the springs and the nuts on the axle ubolts and let it soak in for a few days. They if you use hand tools, use a 1/2 drive ratchet, a 3/8s may not cut it. Best would be to have air tools but it can be done with hand tools.

Find some place where you can leave your boat for the day. That job will be so much easier and safer with the boat off trailer.

Check dealers, I found one in my town that was willing to hoist my boat off the trailer and leave it on the hoist for one day for $75.00. 18' CC.

Block the boat, slide the tralier out then swap them out. It is pretty easy to slide the trailer out on a boat that size. lower front block rear and slide trailer out using bocks to stabilize.

I let my son use the boat for half a day.... A friend would work as well.

Drop them off, take the trailer home and do the work.

Ive done it with the boat on and off. Easyer with it off but not to bad with it on. I just blocked it, pulled tires and went to work. Good luck.
