alliance RV Avenue 2021 SUSPENSION EQUALIZER SYSTEM
In the Alliance RV Avenue 2021, the suspension equalizer is a key part of the complex suspension system. The suspension equalizer is designed to make sure that the weight is distributed evenly and to improve towing and trip performance as a whole. It is an important part of making sure that the ride is smooth and stable. By spreading the weight across the axles in a smart way, it stops uneven tire wear, reduces chassis flex, and makes towing more stable. The suspension equalizer’s careful design shows how dedicated the Avenue is to improving RV owners’ comfort, safety, and general towing experience, whether they are driving on winding roads or going on long trips.
SUSPENSION EQUALIZER SYSTEM
Equipped with dual 6,000 lb. Dexter Axles, a MORryde CRE3000 Suspension System and upgraded Wet Bolt Kit w/ heavy duty shackle links, you will find that this set up will give you smoother towing than a conventional equalizer and leaf springs and better protection of your RV from damaging road shock.
The CRE3000 is located between the tandem axles, replacing the steel equalizer (see below). Designed uniquely to work with your steel leaf spring suspension to improve overall towing performance.
CRE3000 Parts Breakout:
- Equalizer Beam
- Rubber Compression Spring
- Spring Carrier
- Plastic Glide Pad
- Bronze Bushing
- Hex Coupler Nut
- Control Beam
CRE3000 Rubber Shear Spring Inspection
The rubber springs should be periodically inspected for deterioration. If the tabs that protrude from either side of the spring carrier are touching the top of the beam arm, the spring rate of the spring has been affected and the equalizer should be replaced. NOTE: It is normal to see rubber spring weather checking, which is small surface cracks in the rubber, and does not require replacement. It is also common to see minor tearing or cracking of the rubber around the edges.
HD Shackle Links and Wet Bolt Kit
The axles and suspension systems are installed with heavy-duty shackle links and greaseable “wet” bolts with bronze bushings for enhanced durability and less maintenance.
The breakaway switch is a critical safety component of the RV brake system. You will find this located on or near the fifth wheel pin box, if the fifth wheel and the tow vehicle become separated during towing, the line will pull the plunger out and immediately activate the trailers brakes. Always make sure your breakaway switch is in working order. To test your breakaway switch, while the RV is still hitched to the tow vehicle, disconnect the tow plug from the vehicle and then pull the breakaway pin out, only to the first stage, and you should hear the brakes engage.
NEITHER THE BREAKAWAY SWITCH NOR THE TRAILER BRAKES SHOULD EVER BE USED AS A PARKING BRAKE.
ENSURE THAT THERE IS ENOUGH SLACK IN THE BREAKAWAY SWITCH CABLE TO ALLOW FOR TIGHT TURNING RADIUSES.
The tow plug (7-way wire harness) is wired to your RV to connect electrical power from the tow vehicle for the RV brakes, taillights, clearance lights, turn signals, and brake lights. The wiring to operate your brakes must be the same size in both the tow vehicle and RV. Regularly inspect your tow plug for corrosion and build-up, and clean as needed. If damage is noticed, have the tow plug repaired by an authorized RV technician.
PIN BOX MAINTENANCE
- Regularly inspect the kingpin for excessive wear.
- Inspect the skid plate for a neutral/centered position.
- When the trailer is disconnected from the tow vehicle, an equal gap of approximately 1-1/4” should be between the lip of the skid pad and the rubber compression bumpers. It is normal to be able to slightly move and twist the skid pad assembly with hand force.
- Inspect the retainment rods for excessive wear.
- Inspect the plastic glide pads for excessive wear. The pad should be no less than ¾”
- Periodically check hardware torque values.
- Check and grease bearing(s) once per season. If more grease is needed, add it to the bearing assembly.
DO NOT MIX LITHIUM, CALCIUM, SODIUM OR BARIUM COMPLEX GREASES. MIXING OF THESE CAN CREATE A CORROSIVE TOXIC CHEMICAL WITH FUMES THAT CAN RESULT IN SERIOUS HEALTH ISSUES.
NOTE: During the hitching procedure, the bottom of the trailer’s pin box should encounter the hitch skid plate ramp.
- Place blocks against the front and rear of each RV tire.
- If necessary, lower the tow vehicle’s tailgate.
Clearance of the lowered tailgate to the trailer needs to be monitored during hookups, combinations of tow vehicle and trailer have little or no clearance.
- With the RVs front landing gear, adjust trailer height so the bottom of the trailer’s pin box is 1/2” to 1” below the top portion hitch skid plate.
DO NOT ATTEMPT TO HITCH THE RV BY USING THE TRAILERS LANDING GEAR TO LOWER THE KINGPIN ONTO THE HITCH OPENING. THIS COULD RESULT IN THE KINGPIN COMING TO REST ON TOP OF THE SKID PLATE INSTEAD OF WITHIN THE HITCH OPENING, WHICH MAY RESULT IN DEATH OR SERIOUS INJURY.
- Open the jaw on the fifth wheel head.
- Back the tow vehicle slowly toward the trailer until the tow vehicle’s hitch contacts the bottom of the pin box and the kingpin slides into the receiver.
- Latch the fifth wheel hitch in the closed position.
- If space exists between the pin box and hitch, the trailer has not been properly hitched. Do not tow the trailer. Instead, repeat the hitching steps 1-7 until the trailer is properly hitched.
- Connect the electrical and safety cords.
- Raise the tailgate of the truck.
- Do not tow the trailer until a Pull Test has been conducted (covered below).
A: The suspension equalizer is a component in the RV’s suspension system that helps distribute the weight and forces between the axles and wheels for a smoother ride.
A: The suspension equalizer balances the load between the axles by transferring weight from the heavily loaded axle to the less loaded one when the RV is in motion.
A: It helps maintain proper alignment, reduces stress on the suspension components, and enhances stability and comfort during travel.
A: Some RVs allow adjustments to the suspension equalizer settings to accommodate different loads and road conditions.
A: It helps prevent uneven tire wear, minimizes chassis flex, and enhances overall towing and driving performance.
A: Regular inspections, especially before long trips, are recommended to ensure proper functioning and identify any potential issues.
A: Uneven tire wear, swaying during travel, or an uneven ride could indicate issues with the suspension equalizer.
A: Replacing the suspension equalizer may require mechanical expertise and proper tools. It’s advisable to consult a professional RV mechanic.
A: Regular lubrication, inspection for wear or damage, and maintaining proper torque on fasteners are important for its longevity.
A: A well-functioning suspension equalizer helps distribute weight properly, enhancing towing stability and reducing sway.
A: Upgrading the suspension equalizer might be possible, but it’s recommended to consult with professionals who specialize in RV modifications.
A: While both components serve to distribute weight, a weight distribution hitch is typically used for towing trailers, while a suspension equalizer is specific to an RV’s suspension system.
A: The availability of adjustable suspension equalizers may vary based on the RV’s specifications and optional features.
A: Retrofitting a suspension equalizer to older models might be possible, but it’s important to consider compatibility and consult experts before attempting this modification.
