My son and I installed the Dexter HD Suspension set (without the EZ-Flex Idler) yesterday. It took us about 6 hours; having a 20 year old to crawl under the trailer and do the hard stuff was very helpful.
A couple of comments:
1) I sprayed a "rust busting" magic spray over the threads and nuts of all we'd have to take off the day before. I think that this "soaking" time helped make the rusted nuts somewhat easier to get off.
2) Our fifth wheel has shocks installed. In order to lower the axle enough to get the spring ends installed, we had to remove the nut from the lower shock mount (no big deal, if the threads aren't too rusted).
3) Watch the wiring for your electric brakes. In order to lower the axle enough, we had to make some slack in the wire. There were some clips holding the wiring to the frame that we temporarily removed which created the slack, without having to cut the wire and then have to repair it.
4) That ball joint remover tool that has been mentioned earlier is really needed for this job. It would have taken much, much longer without it.
5) The directions included from Dexter are really not very helpful - read them while employing several grains of salt. The pictures and discussion in this thread, however, were very helpful. Thanks!
