I've learned so much from this forum, I though I would pay it back by sharing something I just made for my 5er. Inexpensive and very effective.
I wanted to eliminate the side-to-side sway up front that is typical for 5er landing gear. I know there are commercial solutions like the JT Strongarms and others, but I wasn't prepared to spend $300+ on a solution that I know I could work out myself.
I was stacking several pieces of 2X8 (5-6) under each landing gear foot to limit the extension, and that worked to a degree, but still was not as effective as I wanted it to be.
After a couple of attempts, I wound up with this.
For about $30 in parts (Menards) this eliminated all
of the the side to side sway, and the trailer is now feels solid. I'm also using X-chocks between the wheels to control front to rear wiggle, which has never been much of a concern.
The trick is to make sure there is no axial play in the assembly. It is adjustable for any needed length with the use of the 1.2" threaded rod. Jam nuts tightened after adjusting the length, and snugging up the mount bolts at each end eliminate any play in the assembly.
It quite light too because I used 1.25" wood closet rod for the main rod. Wood??!! Yes, The only forces I needed to control is tension & compression and wood is a good material for this. Some good paint to seal it and it's good to go. I reamed out 3/4" bores in each end and glued 1/2" threaded couplers inside with JB Weld.
I mounted another simple L-bracket on top, under the front belly (you can see it in the top pic) so all I need to do is remove one side and swing it up for stowing. Everything metal is zinc plated, so protected from the elements.
This also allowed me to leave ~12 pieces of heavy board at home and opened up more front storage for better things.
Works great in the driveway and I'm looking forward to trying it during our camping trip next week.
Yeah I'm Dutch, but proud of it
