    28G Momentum Suspension Upgrade Surprise

    Since buying our 28G and considering this our last trailer purchase, I have slowly been making upgrades. Recently I upgraded the suspension using the “Dexter Heavy Duty Equalizer kit with Wet Bolts”. I am happy with the kit; the installation was not difficult and the cost was reasonable. As I pulled the original components off, I was shocked and surprised to find the condition of the original brass bushings. All bushings had wear to the point of no material left. The rear bushings wear was excessive. One bushing came out in multiple small pieces and the other bushing had worn to the point that one side was disintegrated.
    I have put on about 6K miles since the purchase, add another 3500 miles for shipment from Indiana to Washington State and round up to say 10K miles. The amount of wear in the bushings is substantial for the mileage in my opinion.
    Curious to see if others have found this type of wear?
    Due to the excessive wear, I would encourage others to make the upgrade to wet bolts.

    Lots of people have reported the same over the years. I replaced my springs, equalizer and wet bolts on my Momentum after 1 year. They had nylon bushings, but were surprisingly in good condition.

    On a side note, I would get some rust reformer and spray it all over your frame, springs and probably axles. Looks like you have a lot of surface rust, best to address it before it's a problem.

    Thanks for the tip and I agree, that is one of the items on my list this fall

    Identical photos to my suspension upgrade last week! We have a (new to us) 2019 2930RL. Miles on it are two trips from Minnesota to Phoenix. I installed a Morryde shackle \ wet bolt kit for our Dexter 7k axles. My bushings were identical to yours, although 2 of them were totally gone with nothing left for me to remove from the springs. While I was in there I greased wheel bearings and found 2 leaking grease seals that also ruined the brake assemblies.

    I'm now in the process of installing the Roadmaster shock absorber kit.

    The next weekend after the suspension upgrade, I tackled the bearings, found all 4 wheels had blown seals (guessing my fault due to not following the correct process when adding grease via the zerks). After cleaning everything up and testing the brakes all work well. I did replace the bearings and races on one wheel due to slight discoloration on the bearing. I am sure it would have been fine but no reason not the change them once everything was torn down.

    Next Spring, the to do list includes either shock absorbers like you are doing (let us know how it goes) or Sumosprings. Also, I have been looking into upgrading to disc brakes and am toying with upgraded axles as well.

    Common because the spring eyes are not perfectly round. The bronze bushings are regular maintenance items.

    I think on a Momentum, you'd much prefer the Roadmaster shocks. They are great!

    Can of Eastwood rust converter will be a much easier way to go.

    Coming down the home stretch with the Roadmaster shock kit. Its a well designed kit that's not bad to install. I found it easier to take the wheels off when drilling the frame holes. I also did a locknut on the upper mount bolts (see photo). Sorry for the shade / sun in the photo. Was the best I could do at the time.

    This completes my suspension work for now. In my opinion upgrading shackles, wet bolts, and new bushings along with the shock kit are relatively low cost upgrades that are well worth the money and time.

    Thanks for the tip on the Eastwood rust converter! Hoping to have a few other weekends rain free to work on the frame. Since my hunting and camping area is in the middle of the Schneider springs fire in Eastern WA, I may have a lot more time on my hands to get a few projects done. Thanks again.

    Looks great. When I did my initial research on the shock kit, I was also thinking of the lock nut route, so glad to see it worked for you. Any issues drilling into the I beam frame? I always worry if introducing new holes will promote cracking. Thanks for following up with info.

    I was a little concerned at first with drilling holes in the frame, but after getting underneath and looking around, these are basically a few more holes similar to the bolts holding the coroplast in place along the frame. The frame itself is relatively soft and drilled very easy. After drilling, you drive in the 3/8" self tapping bolts and then lock nuts on top of that (when possible to install). I thought about purchasing a 90* drill adapter but in the end I found that long drill bits worked well for the holes.
