| | Trailer Bouncing during Towing
Back before the new year I decided to replace everything on my 1993 bass boat (single axle) trailer -- springs, u-bolts, wheels, tires, hubs, and bearings/races...everything except the original axle.
I haven't towed the trailer more than 20 miles since doing all this, and most of those miles were with the boat off the trailer. But anyway, I was taking the boat over to the marine shop, less than half a mile away from where I keep it, for maintenance, and until I got up to about 20-25mph, the trailer seemed to bounce up and down slightly, like I was driving over a row of small speed bumps. It wasn't so bad that it seemed dangerous, but I could definetly feel the up and down motion while pulling it with my Dodge 1500. It stopped when I got over a certain speed and then pulled just fine. I also remember it doing this also when I first took it back home after replacing everything, with the boat off the trailer.
Any suggestions to what could be causing this? Is everything just 'breaking in'?
Thanks for any input! JBT
