All RideStar™ RHP Trailer
Air Suspension Systems

7. Inspection Guidelines TP-0527
Use Meritor publication TP-0527 as an aid to perform periodic scheduled visual inspections of the RideStar™ RHP air suspension.
Periodic inspection will help prevent “Progressive Wear” to the upper control arm, frame bracket, and axle seat.

8. General Inspection Information
The upper control arm bushings can be visually inspected from underneath the trailer and without any disassembly of components.

9. One Piece Rubber Bushing Two Piece Urethane Bushing

14. Bushing Locations
Determine what type of upper control arm bushings are
present at every location in the RHP suspension; 8 in
total.

15. Identifying Bushing Types
If any of the upper control arm bushings are the 2 piece
urethane inspection as defined in this document &
TP-0527 should be followed.
If all 8 of the upper control arm bushings are the one
piece bonded rubber type inspection as defined in this
document be followed.

16. Periodic/Annual Inspection Reminder
Inspect for loose, broken or missing fasteners. Repair or replace as needed.
Inspect welds for cracks at the axle, frame bracket and upper control arm crosstube.
Inspect the flex member of the air springs for cuts and abrasions. Replace the air spring if it is cut or damaged.
Check for obstructions or interference to the air spring surface that can damage the air spring. Relocate and secure items, such as air hoses, that can contact the air spring.
Check for leaks in the air lines at the air spring bead plate, piston and mounting studs. Replace air lines, fittings or air springs that leak.
Inspect the shock absorbers for worn bushings, oil leaks and dents. Check that the mounting holes have not enlarged.

17. 2-Piece Urethane Bushing Inspection
Once it is determined that the bushings are the two piece urethane type, use a flashlight and inspect all upper control arm bushings (eight (8) in total) to see if the upper control arm has shifted to one side of the frame bracket or axle seat

18. Inspection Result # 1
Shown is how the upper control arm with bushing should look. Bushing flanges should be intact on both sides of the bushing tube and everything is centered within the frame bracket or axle seat. It is still necessary to verify that the system is within the correct operating range.

19. System Operating Range Inspection
To verify that the system is within the correct operating range requires only a tape measure. Take a measurement from center of A-Frame Upper Control Arm pivot bolt to center of Axle seat Upper Control Arm pivot bolt (See Illustration Below) at all four (4) locations. If this measurement is more than 14-3/16-inches (360 mm) or less than 13-13/16-inches (351 mm) at any of the four locations: Replace all eight bushings at the next available opportunity.
If the measurement is not within the acceptable operating range of 13-13/16"–14-3/16" ( mm), replace all eight bushings at the next available opportunity.

20. Inspection Result # 2
Shown is the upper control arm with bushing shifted slightly to one side. The bushing flange on the side that the upper control arm has moved towards will be worn, but still intact. This condition requires neutralizing the suspension assembly and re-aligning the trailer. This should be done at the next available opportunity.
The urethane bushing flange is worn, but intact.

21. Neutralizing Suspension Upper Control Arm Pivot Bolts
Neutralizing the RHP means to get the adjustable pivots at their centered (relaxed) position prior to aligning the axles. With the suspension at ride height, loosen the adjustable pivot connections on the roadside at the upper control arm. Adjust the front axle lower control arm to 21.50” center of bolt to center of bolt (see illustration). Align axles per Section 4 of Maintenance Manual mm14s.

22. Inspection Result # 3
Shown is the upper control arm with bushing shifted slightly to one side. The bushing flange on the side that the upper control arm has moved towards will be torn, or missing. No indication of significant wear is present between the upper control arm and the frame bracket or axle seat. This condition requires bushing replacement if any one (1) of the eight (8) bushings exhibit this condition. No “Progressive Wear” has occurred at this point. This condition requires bushing replacement at the next available opportunity.
The urethane bushing flange is torn or missing

23. Inspection Result # 4
Shown is the upper control arm with bushing shifted & clamped to one side. The bushing flange on the side that the upper control arm has moved towards will be missing. Significant wear is present between the upper control arm and the frame bracket or axle seat. This condition requires bushing replacement immediately so further component damage does not occur.

24. Inspection Result # 5
Shown are the air springs and shock absorber leaning in a defined direction. This is a prime indication that progressive wear has occurred and rebushing should be scheduled immediately. There is no need to inspect any further if this condition exists at either one of the axles.

25. Bonded Rubber Bushing Inspection
Once it is determined that the bushings are the bonded rubber style, use a flashlight and inspect all upper control arm bushings (eight (8) in total) to see if the upper control arm has shifted to one side of the frame bracket or axle seat

27. Periodic/Annual Inspection Reminder
Inspect for loose, broken or missing fasteners. Repair or replace as needed.
Inspect the welds for cracks at the axle, frame bracket and upper control arm crosstube.
Inspect the flex member of the air springs for cuts and abrasions. Replace the air spring if it is cut or damaged.
Check for obstructions or interference to the air spring surface that can damage the air spring. Relocate and secure items, such as air hoses, that can contact the air spring.
Check for leaks in the air lines at the air spring bead plate, piston and mounting studs. Replace air lines, fittings or air springs that leak.
Inspect the shock absorbers for worn bushings, oil leaks and dents. Check that the mounting holes have not enlarged.

28. Inspection Result # 1
Use a flashlight and inspect all upper control arm bushings (eight (8) in total). Visually inspect all sixteen (16) front and rear upper control arm thrust washers. Shown is how the upper control arm with bushing should look. Thrust washers should be intact on both sides of the bushing tube and everything is centered within the frame bracket or axle seat. This condition requires no service.

29. Inspection Result # 2
Use a flashlight and inspect all upper control arm bushings (eight (8) in total). Visually inspect all sixteen (16) front and rear upper control thrust washers. If any thrust washer is missing it should be replaced at the next available opportunity.
TP-06112; Installing Two-Piece Replacement Thrust Washers document covers this result.

30. Inspection Result # 3
Use a flashlight and inspect all upper control arm bushings (eight (8) in total). Visually inspect all sixteen (16) front and rear upper control thrust washers. If any thrust washer is cracked or no longer concentric (dropped down) to the connection and still in place, it should be replaced at the next available opportunity.
If a thrust washer is cracked, try removing it with a pair of pliers. You may be able to pull it out and replace it. TP-06112; Installing Two-Piece Replacement Thrust Washers document covers this result.
If thrust washers can not be removed or is no longer concentric to the connection, taking the connections loose only on the affected end of the upper control arm is required. Replace all four (4) composite thrust washers with steel thrust washers at this time.

31. Neutralizing Suspension Upper Control Arm Pivot Bolts
Neutralizing the RHP means to get the adjustable pivots at their centered (relaxed) position prior to aligning the axles. With the suspension at ride height, loosen the adjustable pivot connections on the roadside at the upper control arm. Adjust the front axle lower control arm to 21.50” center of bolt to center of bolt (see illustration). Align axles per Section 4 of Maintenance Manual mm14s.
