I didn't notice this untill I followed my wife towing our Shasta Airflyte. It bounces more than I think it should. The ride height seems correct. Springs ( nice arc ) / shackles / bushings all good. I noticed it a bit when towing myself because you can feel it tugging as it bounces. You can't really see it too much because the trailer is so close to the back of my tow vehicle. There is a few ways to try and address this and I am wondering if there is any experience from others here to share. Good and bad. Hi Friends, Late to the party. Juke box said his springs/shackles/ and bushings are all good. I think we need more of a definition for good. Forgive the questions. I don't want to appear pesky, but I think we need more details - maybe its just me, lol. Are the through bolts clean and or the bushings new or replaced - plastic or brass? My westerner had zerk fittings on the through bolts originally, but they were clogged with dried grease and the through bolts were dry and worn. Are they newly replaced, or recently serviced? You said the springs were good. Again, not sure what you mean. Has the spring pack been taken apart, leafs cleaned and rust removed, and then regreased between the leafs before the spring pack was reassembled? Thats what I did based on the advice I got over at Repairing Yesterday's Trailers. I always thought that all the parts of the leaf spring suspension work together. If one of them is rusty or dry or the bushings, shackles are worn, it's not working efficiently. I hope you figure this out. Rod

Because your rig is only a few hundred pounds you are getting away with it. In reality you have a miss designed trailer that has too stiff of springs. I know the springs are too stiff. I thought about removing a leaf or two but lowering tire pressure improved the ride dramatically without going to low to where it would damage the tires. My point was that too much air will make it bounce more, not nearly to the extreme mine does of course. While I wasn't clear on that point the point was the tire pressure is important too. Finding the correct amount for your trailer. Some people will see max pressure on the tire and just air to that.

Finding the correct amount for your trailer. Some people will see max pressure on the tire and just air to that. Most vintage trailers need to run the tires at max air pressure to prevent excessive heat build up. Tire mfgs have suggested that for years. A light trailer like you are hauling your kayaks on it doesn't matter as you are way over tired but a camper loads its tires by weight and wind pressure. In fact many recommend running up to 10% over max to get better mileage and better control plus increased tire life.
