Torsion Axle Care and Maintenance Torsion Axle Care and Maintenance

Congratulations on the purchase of your new trailer. This trailer manufacturer has
chosen the Tie Down Engineering Eliminator Torsion Axle for your trailer’s
suspension requirements. There are several important facts in using your new
trailer with the Eliminator Torsion Axle.

Four cords inside the axle housing handle suspension travel and shock absorption.
As the wheel moves up or down, the rubber cords compress, offering a progressive
rate of resistance.

Benefits to this system are: Independent suspension, each wheel acts independently for a
smoother ride. Trailer rigidity, the axle is bolted to the trailer frame. This acts as an
additional cross member which stiffens the frame, reducing flex in cross winds and rough
roads. Progressive “spring” rate, small bumps are handled by a soft initial rate, while
larger bumps use a stiffer rate. This makes for a smoother ride over all types of roads.

Corrosion resistance: Each Eliminator torsion axle tube is galvanized inside and out.
Since there is no metal-to-metal contact as with springs, bare metal is not exposed that
promotes corrosion. The torsion arms are available with E-coat or with hot dip galvanizing.
Longer life with fewer problems. Reduced un-sprung weight: The Eliminator torsion axle
tube is bolted to the frame. The moving parts are reduced, lowering the weight that the
“spring action” must move. This results in a smoother shock action.

Stainless Steel Wear Sleeves: Rear oil seals ride on stainless steel sleeves on the 3500
series, 5000/6000 and 7000 series axles. This reduces the chance of worn seals due to
corrosion build up on the spindle surface where the oil seal meets the spindle surface.
Backing Plates are built into the casting design of the torsion arms. All surfaces are
machined to assure that the backing plate and spindle are “square” to each other. This
assures a better fitting brake assembly.

The Eliminator Torsion Axle has an industry first with its removable spindle. Gone are the
days of sitting by the side of the road when the spindle is damaged due to extreme
bearing failure or an accident. Available from your trailer manufacturer or dealer is a
spare tire-hub-spindle carrier that replaces the old style spare tire carrier. This gives you
great peace of mind by having a spare tire, a spare hub with bearings and grease and
something no one else offers, a spare spindle that can be removed with standard tools.

Road Side Repairs

When required, you have several options when confronted with a flat tire, bearing failure
or spindle damage. Flat tires should be handled like any other trailer tire change. Make
sure trailer is on level or near level ground. Loosen lug nuts on wheel. Use jack on trailer
frame to elevate tire in order to place spare tire on the hub. Make sure all lug nuts are
securely tightened before moving trailer. Re-check lug nuts after several miles to make
sure they are tight. Bearing failure is usually discovered by a loud grinding noise or
wheel wobble. If there is obvious bearing damage, jack up the trailer to remove the tire.
