If you're mechanically inclined it's really a straight forward job, but a little labor intensive. Like others have said be prepared to cut off some very rusted bolts. I did a dual axle trailer from soup to nuts,(axles,springs,equalizers...) in about 5 1/2 hrs, last summer by myself. If I was doing it again I bet I could whittle it down to 3 1/2 to 4 hours. Buy the Dexter suspension upgrade kit that includes all the new wet bolt hardware. Only a couple bucks more and it's going to be apart anyways.
