The "WARNING" symbol above is a sign that the installation procedure has a safety risk involved and
may cause death, serious personal injury and/or product or property damage if not performed safely and
within the parameters set forth in this instruction sheet.
Introduction
This document details the steps to remove a damaged Correct Track™ hanger and replace it with a new hanger.
Safety
Always lift trailer by the frame, never the axle or suspension. Do not go under the trailer unless it is
properly supported by jack stands. Unsupported trailers can fall causing death or serious injury. This
repair should only be completed by an authorized service technician.
Always wear eye protection when performing service or maintenance to the trailer. Other safety
equipment to consider would be hearing protection, gloves and possibly a full face shield,
depending on the nature of the service.

CORRECT TRACK™ HANGER REPLACEMENT
Failure to remove flammable objects, obstructions, tires, axles or additional suspension components
may result in death, serious injury and/or severe product or property damage.
6. Using heat-resistant material, cover any remaining components within the welding area that could not
be removed or relocated.
7. Stabilize axles with floor jacks.
8. Measure the distance between the axle hanger to be replaced and the adjacent hanger (Fig. 1). Record
the measurements.

9. Remove cam and bolt assembly from the hanger (Fig. 2) and set aside.
NOTE: I-beam removed for clarity.
NOTE: Record position of cam for later use.
10. Lower axle and spring nearest the hanger to be replaced.

Installation
1. Measure and mark the frame where the new hanger will be mounted (refer to Preparation section).
Make sure the new hanger is properly aligned.
2. Weld the new hanger into place using a 1/4" continuous weld bead on all four sides (Fig. 4).
Post-Weld Cleanup
1. Allow welded areas to cool completely.
Overspray or dripping of paint and solvents onto an unprotected oor can create a slipping hazard.
Slipping on wet surfaces can causes personal injury. Use a drop cloth or other similar protective
material on the work area to prevent slipping.
2. Chip off any flux from the welds and inspect the welds for completeness.
3. Paint over the welded areas with rust inhibitor spray paint or brushed-on paint.
NOTE: Spray and brush applications will have uniquely different appearances.
4. Let painted areas on the chassis/frame dry completely.
5. Reinstall all previously removed or relocated components (steps 3-5 of the Preparation section) to their
original location.
6. Raise axle and spring to align the spring holes with the hanger.
7. Reinstall Correct Track cams on front and back sides of the hanger in their original positions (step 9 of
the Preparation section).
8. Insert shoulder bolt from the back side of the hanger and extend bolt through the cams and hanger.
9. Torque shoulder bolt nut to 30-50 ft-lbs.
10. Reinstall axle, tire and other components previously removed.
11. Lower the trailer to the ground.
