Not sure about yours, but some boxes had a screw held with a locking nut
accessible from the top of the box. Loosen the locking nut, and with the
steering straight ahead, turn the screw in till snug, then back off a tad
and tighten the locking nut. This solved a few highway speed wobbles in a
few vehicles I owned over the years.
