Bob,
Both gear leg fairings need to be aligned with the fuselage center
line (for lateral trim purposes), No balancing needed. The wheel pants
need to be statically balanced fore and aft. First remove the wheel
pants and build a jig that will freely support the fairing along the
axle center line first. The rear of the pant should be considerably
heavier. Then add weight to the very front of the fairing until it
balances. You can add the weight to the outside, then when they balance,
epoxy the weight inside to the front of the fairing. Lead shot and epoxy
work great for this.

How does one balance gear leg pants and wheel fairings?
Thank you for your contribution. Bob Haas.

Good Afternoon,
I had some serious shimmy problems in my Vans RV3 which has
similar gear/leg construction.
Nearly all of my shimmy problem was solved by simply balancing
the pant/wheel fairings. I also reduced tire press. to 22 pounds.
Bench testing revealed considerable aft weight prior to
balancing.
