A torsion axle for a trailer for transporting a load such as a pontoon boat. The torsion axle assembly is part of a wheel unit for maintaining stability for the trailer during transport. The torsion axle is assembled to have two pairs of resilient elements and an elongated shaft housed between inner and outer elongated sections. The inner and outer elongated sections are held together temporarily by a weld and then releasably held together by releasable fasteners in a normal use position.

[ I claim:] [1.] The method of assembly of a torsional axle assembly comprising the steps of:forming a first elongated outer section having at least three sides formed at right angles in cross section;inserting a first pair of elongated resilient elements each into an opposed interior corner of said

[ I claim:] [1.] The method of assembly of a torsional axle assembly comprising the steps of:forming a first elongated outer section having at least three sides formed at right angles in cross section;inserting a first pair of elongated resilient elements each into an opposed interior corner of said outer section;placing an elongated shaft having a square cross section within said outer section in a nested relationship with said first resilient elements, leaving a pair of free outer surfaces of said shaft;placing a second pair of elongated resilient elements each into engagement with a said free outer surface of said shaft;forming a second elongated outer section and engaging said first section therewith to enclose said first section and form a right angular interior therewith, whereby said free outer surfaces nest with said second resilient elements;forcing said first and second sections together into a normal use position against resistance of said pairs of resilient elements;temporarily fastening said first and second section together in said normal use position, and releasing said force; andreleasably fastening said first and second sections together for normal use to obviate failure of said temporary fastening during normal use.
