Toyota Highlander 2022 Owner Experiences Sagging Rear Suspension after Installing Bike Carrier, Suffers Bottoming Out on Minor Bumps
The 2022 Toyota Highlander, a popular unibody SUV, has been noted for its five-star safety rating from NHTSA and Top Safety Pick+ designation from the IIHS, despite a noticeable sagging issue when carrying extra cargo, such as bike carriers. This sagging can lead to safety concerns, particularly if the headlights point upwards, potentially blinding oncoming drivers.
While specific aftermarket solutions designed explicitly for the 2022 Highlander may not be readily available, several typical and effective methods can help prevent rear sag under load.
Helper Air Springs or Airbags
These additional support systems, installed alongside the factory suspension, can provide extra support when carrying heavy loads. They are a popular choice for many SUVs and can help level out the Highlander when towing or carrying heavy cargo.
Load-Leveling Coil Springs or Progressive Springs
Replacing factory springs with stiffer aftermarket springs designed to handle extra weight is another option. These springs can help maintain the ride height and reduce sag.
Upgraded Rear Shocks
Performance shocks can help maintain ride height and reduce sag, making them a valuable addition to the Highlander's suspension system.
Suspension Helper Kits or Blocks
Some kits add spacers or blocks to the rear suspension to compensate for sag. These kits can help improve the Highlander's rear suspension firmness.
Given the Highlander's relatively new status, compatible suspension helper kits or airbags specific to the 2022 model may need to be sourced from specialized aftermarket companies or off-road accessory suppliers. It's essential to confirm fitment and compatibility with the exact model year.
Upgrading to a stronger set of coil springs designed explicitly for hauling can provide a more permanent solution for the Highlander's soft suspension, but it might be more expensive and require professional installation.
Coil spring spacers are another option to increase ride height and prevent sag in the Highlander. Affordable options like Coil SumoSprings can help prevent the Highlander's coil springs from compressing too much under load.
Air springs/air bags, like Air Lift systems, offer adjustable support and can help level the vehicle when carrying heavy loads or towing. They can be more expensive than coil spring helpers.
Before purchasing aftermarket suspension components, it's crucial to research different brands and products to ensure compatibility with your Highlander model and year, and look for customer reviews and installation instructions. Some users have explored aftermarket solutions like Sumo Springs, AirLift bags, or SuperSprings to stiffen the rear suspension and mitigate the sagging.
It's essential to consider the specific needs and budget when exploring solutions to address the Highlander's suspension sag when carrying extra cargo. Professional installation is recommended for some of the aftermarket suspension options, especially if you are not comfortable working on your vehicle's suspension.
Lastly, it's worth noting that installing aftermarket suspension components can void some parts of your warranty, so it's always advisable to check with your dealership before making any modifications. Maciej Jakub Tyszkowski, a Toyota Highlander owner, has posted on the Toyota Highlander Owners Club Facebook page asking for solutions to prevent sagging when a bike carrier is loaded. Several users on Reddit forums have reported similar issues with their 2022 Highlanders sagging noticeably when a bike rack is loaded, even with a relatively lightweight rack.
In conclusion, while the 2022 Toyota Highlander may experience sagging when carrying extra cargo, several aftermarket solutions can help address this issue, making your driving experience safer and more comfortable.
Sports enthusiasts who own a 2022 Toyota Highlander and often carry bicycles or other heavy equipment might want to consider upgrading their vehicle's suspension to enhance safety and prevent sagging. For instance, installing helper air springs or airbags can help provide an extra support system under heavy loads, reducing the risk of safety concerns such as blinding oncoming drivers due to the headlights pointing upwards.
