A retractable tonneau cover is a convenient and stylish way to protect the truck bed and cargo. But what do you do when the cover gets stuck halfway or won’t open fully? There can be a few reasons for a sticky or jammed retractable tonneau. Let’s explore some potential causes and solutions for diagnosing and fixing a retractable truck bed cover that won’t open completely.
Is Lack of Lubrication Causing Sticking?
One common culprit for a retractable tonneau cover that sticks or jams mid-open is a lack of lubrication in the rail system. Most retractable covers have side rails that the cover glides along when opening and closing. Over time, the rails and rollers can accumulate dirt and dry out. This friction will start to make the cover stick at certain spots along the rails.
Regularly applying lubricant to the rails can prevent this sticking and keep everything sliding smoothly. Use a silicone-based spray lubricant made specifically for tonneau covers. Don’t use WD-40, as it can actually draw in more dirt over time. Spray lubricant onto a rag and wipe along the entire length of the rails every few months. Make sure to fully clean the rails first and allow them to dry before lubricating. This small bit of maintenance can prevent sticking and keep your retractable cover opening and closing easily for years.
How Can I Get My Stuck Retractable Tonneau Moving Again?
If your retractable cover is already sticking partway open, don’t force it. Applying more pressure will likely damage the cover system. Start by generously lubricating the problem areas of the rails as described above. Open and close the cover multiple times to distribute the lubricant. This may free up the sticky spots and get your cover gliding smoothly again.
Be patient and persistent in working the lubricant into the rails and rollers. If you have a compressed air can, try blowing out any debris in the rails while the cover is open. Opening it a few inches at a time and applying more lubricant may help release stubborn stuck spots. Avoid using any chemical cleaners or solvents on the rails. With proper lubrication and manual working of the cover, you should be able to get it opening fully again.
Could Rust and Corrosion Be the Culprit?
Along with lack of lubrication, rust buildup on the rails can also cause sticking with retractable tonneaus. This is especially true for covers installed in areas with cold winters where they’re exposed to snow, ice, and road salt. The rails may become corroded from this exposure. And rust particles will abrade the gaskets as the cover moves, creating even more friction and sticking.
Carefully inspect the rails for any visible rust spots or corrosion. Use a rag and a gentle abrasive rubbing compound to remove the rust from affected areas of the rail tracks. Avoid harsh abrasives or steel wool that can damage the rail surface. Then lubricate the rails to prevent rust from returning. Regular rail lubrication and tonneau gasket maintenance will help combat rust buildup over time.
For retractable covers in harsh winter climates, you may want to remove the cover for storage during the snowy months to prevent excessive rusting of the rails. An annual deep cleaning and fresh lubricating of the rails each spring will help reduce sticking from winter rail rust issues.
What If the Rails Are Heavily Rusted?
In cases of extreme rust and corrosion damage, the rails may need to be replaced for the cover to slide properly. Check with the manufacturer, as some retractable tonneau systems have replaceable rails available. Measure the length and dimensions of your original rails to find the correct replacement parts. Avoid DIY home-rigged rails, as the wrong design can damage the cover mechanism or not retract correctly.
Installing fresh new rails will provide clean, smooth tracks for your retractable cover rollers. Be sure to lubricate the new rails during install per the manufacturer instructions to prevent seizing. Get in the habit of periodic rail lubricating and rust-prevention care to maximize the lifespan of your new rails. With clean rails, your retractable tonneau should open easily once again.
Do You Have a Faulty Locking System?
Retractable truck bed covers utilize various styles of locking mechanisms to secure the cover closed or at intermediate open positions. Malfunctioning locks are another cause of sticking and uneven cover retraction. Issues like loose or warped lock components can obstruct the cover’s path when opening.
Inspect all locking points along the rails closely to identify binding or catching. Many systems use spring-loaded slam latches that may need adjusting or replacing if the springs lose tension. Some covers have single housing locks with rotating arms that can slip out of alignment and need realignment. And motorized electric locking models can suffer wiring or connection problems over time.
Refer to your owner’s manual for the proper operation and adjustment procedures specific to your retractable cover lock style. Repairing or replacing worn latches, adjusting catch alignment, or reconnecting any loose wiring should have your cover opening freely again. Always double check full lock engagement in the closed position before trying to retract the cover.
When Should the Locking System Be Replaced?
If your cover has multiple failing locks or severely damaged components, a full locking system replacement may be the best solution for restoring proper retractable function. Moisture corrosion, damaged housings, and excessively worn latches will require replacement parts. Check with the manufacturer for replacement lock kits designed for your specific retractable cover.
Have a helper on hand for easier installation of fiddly small parts when swapping lock systems. Be sure to lubricate any sliding components in the new locks per the kit instructions for smooth operation. Taking the time to repair or replace faulty locking hardware prevents fighting against stuck locks when opening your cover.
Is the Cover Not Unlatching from Closed Position?
Before a retractable tonneau cover can open, it first has to unlatch from the fully closed and secured position. If the cover seems stuck when you first try retracting it, the issue may be that the latches are not releasing properly. This can happen when the latch mechanisms become misaligned from extended use or damaged from forcing against stuck points.
Double check that all security latches are disengaged before trying to open the cover. Feel along the rails to identify any stuck latch points not releasing fully. Refer to your owner’s manual for the proper latch operation and realignment procedures. Adjusting strikers, spring tension, and latch hook angles may get them cleanly unlatching again.
Lubricate any stiff or sticky latch components and work them through their full range of motion several times. Cleaning out compacted debris can also free up binding in the mechanisms. Getting the security latches smoothly unlatching allows the cover to then retract without obstruction. Be patient and methodical in adjusting the latches until the cover releases freely.
When Should You Replace Damaged Latches?
If latches are severely bent or broken, replacement will be needed for proper functionality. Manufacturer-approved replacement latch kits will bolt directly into the existing striker holes for easy installation on most retractable covers. Inspect the latch housings for cracking damage and replace if compromised.
Use a quality marine-grade waterproof grease on the latch components during reassembly to prevent rust seizing. Cycle the new latches multiple times with the cover open to ensure smooth operation before fully closing and testing security. Resolving any latch release issues will prevent headache each time you go to open your retractable tonneau cover.
Does Your Cover Need Professional Service?
If you’ve methodically tried all the troubleshooting and maintenance tips above, but your retractable cover still sticks or jams, it may be time to seek professional help. An experienced truck accessory shop can inspect the cover operating components for any underlying damage or wear issues. Hardware adjustments and replacements often require special tools to avoid causing further damage.
Seeking timely professional assessment and service can oftentimes restore smooth functioning and avoid the need for a full tonneau replacement. Be sure to ask for a maintenance schedule and tips for preventive care of your retractable cover system. Investing in some periodic professional tonneau health checks and service can optimize performance and expand the working life of your cover.
