Any tips on replacing both springs on one side? I broke the right rear so I’m going to replace both front and rear on that side. Is it necessary to have the weight off both tires on the rear axle or can I just jack up the right side, place jack stands under trailer and axle? I had to replace the rear axle last year and I did it with the boat on the trailer. I know it’s better to have an empty trailer but it wasn’t possible and it wasn’t that bad with the boat on the trailer. According to the specs from the dealer I purchased from the spring is 25 1/4. I’ve already located 2 springs. This is a 2017 tandem Trailer. 3500 lb axles. I just had all the bushings and hardware replaced on this trailer less than 2 years ago because I had a cracked hanger bracket. Thanks
