The spindle will be inserted into the axle and then welded at the end. The axle tube will need to be a minimum of 2" x 2" x 1/4" . This will be the axle tube item number 124997.

Fitment
Supposing this stub goes inside a 2x2x1/4 tubing ? Thanks
1 answer-
UltraTowExpert11· 13 years ago
This spindle should fit into 2" square tubing with a 1/4" wall thickness. Northern Tool recommends measuring the inside diameter of the tubing to ensure it will accommodate the spindle.
