Expert Answers about Chevrolet Lift Supports


  • Troubleshooting Thule Bike Rack On 2019 Subaru Outback Wagon with Automatic Liftgate
  • The issue you are experiencing is likely that the lift struts and motor aren't able to support the extra weight of the bike rack itself on the hatch. The motorized hatch is designed to retract when it experiences resistance like if it were to hit a garage door for instance when opening. In this case it is the safety feature that you are having issue with. You will have to use the manual lift function and may need to even support the hatch when opened.

  • Can Firestone Air Bags F2558 On 2019 Nissan Frontier Support Weight Of Axle When Jacking Vehicle?
  • Yes, Firestone airbags such as the # F2558 you have installed on your 2019 Nissan Frontier can support the weight of the wheels and axle. This is due to Firestone using a roll crimp that holds the endplate to the rubber. With that said, if you'll be leaving the truck like that for an extended period of time like a day or two, I'd still go ahead and use jackstands to support the weight of the axle anyways, but that's more of a personal preference.

  • Troubleshooting Unlocking the TorkLift Fortress GasLock Kit for Propane Tanks
  • I contacted Tech support at TorkLift for your issue with the Fortress GasLock Kit, # TLA7770. They stated that while they have in the past had a few that fit tightly at first, they have not had any feedback of them not opening or the keys breaking off. You may just need to put a little more force to it. I asked about suggestions to loosen this up, lubricate the tumblers in the barrel. They responded with suggestion of white lithium grease or graphite. But do not use WD40 or something...

  • Troubleshooting Lippert Stabilizer Jack Not Lifting in Auto Level Mode
  • The Lippert Components High-Speed Power Stabilizer Jack - Black Waterproof Switch Kit - 30" Lift # LC298707 has a threaded rod that runs from one side to the other. It sounds like there is an issue with the leg either showing a little resistance so it only moves one leg to try and level to that other jack leg. We have the support for the leg, and the foot, motor and switches as replacement parts but the components that you describe not functioning we do not have replacements for so there...

  • Troubleshooting Trailer Break-Away System that Isnt Fully Applying Trailer Brakes
  • The first thing I'd check is that the break away battery is fully charged and in good condition. Check the terminals for corrosion, clean them if needed. Then, you'll want to take a look at the wiring instructions for a common break away system that I've linked for you, and ensure that the system has been wired properly. With the pin pulled, use a multi meter like part # PT89ZR and make sure you're getting a full 12 volts at the brake magnets. I would also check the brakes for proper adjustment....

  • Scissor Jacks Slowly Lowering on Their Own
  • I spoke with my contact at Ultra-Fab, who is one of the leading names in stabilizer jacks, and she said that she has never come across the issue that you are having. The best we could come up with is if you are using the stabilizer scissor jacks to jack up your trailer instead of stabilizing it once it is already jacked up then that could have possibly damaged the scissor jacks. Since your scissor jacks seem to be defective I recommend checking with the manufacturer to see if they have...

  • 2012 Dodge Caravan With Failed Airbags Troubleshooting
  • Per Air Lift the leading cause of air bag failure is tearing or punctures from flying debris or interference with other parts underneath the vehicle. It may be worth taking a look at your existing system and inspect for adequate clearance under the vehicle to try to prevent future failures. A couple of measurements from the instructions on the Air Lift AirLift 1000 Air Helper Springs for Coil Springs # AL60814 include checking the tail pipe clearance to ensure that it is at least 2-3...

  • Brakes on Only One Trailer Axle are Working
  • There is no setting on the Brake Controller that would make one axle work, and one not. I would first use a circuit tester like part # PTW2993 and verify that the brake magnets on the axle that does not seem to be working are getting voltage. Use the tester on the brake output wires as close as possible to the brake magnets while a helper activates the brake override switch on the brake controller. If the magnets are not getting power, you have a wiring issue. You will have to check the...

  • Brake Controller Works When Brake is Activated but Trailer Brakes Do Not Work
  • I would start by using a circuit tester such as part # PTW2993 on the brake output pin on the trailer connector while activating the override switch, to see if you are getting any output at the connector. If this checks out, probe the brake output wire just before it reaches the brake assembly. This will verify that the power is reaching the brakes. We have a brake controller testing video for you to review, see link. There are a few other problems that might be causing your problem. The...

  • Troubleshooting Tire Rubbing at Full Suspension on 2004 Coachmen Viking Tent Trailer
  • Other than flipping your axles, the only way to change the ride height of your trailer is to change the hangers unless your trailer suspension is really bad and has been very overloaded. It sounds like you research things like axle capacity so I'd be shocked if your suspension was that bad without you being very aware. If you want to change out your hangers, I've linked the page to all your options. Different shackle straps won't give you that kind of lift. There is only one suspension...

  • Troubleshooting Trailer Valet JXS Trailer Jack No Longer Fully Extending With Cordless Drill Adapter
  • It sounds like you may need to add some more grease to the Trailer Valet JXS Trailer Jack # TV64FR. With the performance of the jack getting worse the portion of the screw inside the jack is likely drying out making operation with the Drill Attachment # TVDA more difficult on the drill. There is a grease zerk on the back of the jack below the crank handle area.

  • Maxx Air Fan Lid Unable to Fully Open
  • It sounds like the lift arms aren't able to keep the lid up to the fan's fully-opened height. There are a few things that may cause this. You may have already tried this, but push the manual knob in when the you've reached the fully-opened position to engage the locking mechanism. If that doesn't solve the problem, there are some troubleshooting steps to take. First, check to make sure the bolts of the lift arms are fully tightened. If there are loose components, it may not be able to...

  • Auto Level Operation Of The Lippert Electric Ground Control TT Automatic Leveling System
  • The tongue jack for your Electric Ground Control TT Automatic 5-Point Travel Trailer Leveling System # LC672136 is supposed to lift up so that the other jacks can properly level out your trailer and does require you to go back and lower the tongue jack once the others are set in place.

  • Leaking Air Helper Spring System on 2004 Honda Pilot
  • Actually, the Air Lift # AL60740 can be used on 2WD or 4WD vehicles, I've confirmed this with my Tech Support contact at Air Lift. Usually, a leak occurs at points where the air line was cut to length. It's important that these cuts be perfectly square, so using a tubing cutter like # AL10530 to get nice clean cuts is very important. The easiest way to find the leak is to add air to the system, then take some liquid dishwashing soap and dilute it with a small amount of water. Use a small...

  • Removing Broken Lippert Electric Stabilizer jacks
  • If your Lippert electric stabilizer jacks will not operate via their motors or via the manual crank (which is now broken) I am afraid the only option to let you move the trailer is to remove the damaged rear stabilizer jacks. You will need some method of safely stabilizing the rear of the trailer so that you can unbolt the damaged jack(s) and move the trailer. I understand that your rear jacks are off the ground already but for your safety I urge you to use stands like # UF48-979003 any...

  • Troubleshooting Tandem Axle Boat Trailer Equalizer Contacting Frame on Rear Spring
  • There are a few things I would recommend checking before you start swapping parts. First will be to check the weight distribution with the boat on the trailer. Typically when the rear is hitting the frame like you have the weight may be to much on the rear of the trailer and the boat should be moved forward or gear on the boat moved to better evenly distribute the weight across the entire trailer. Second I would ensure that the boat trailer is pulling level when connected to the tow...

  • What can I do to Decrease the Vertical Wobble on My Swagman Trailhead 4 # S63381?
  • I am sorry to hear that you are having issues with your hitch pin on your Swagman Trailhead 4 # S63381. One of the troubleshooting methods that we recommend for the looseness issue is to wiggle the rack up and down as you install/tighten the hitch pin. This can help with tightening. Also, another route is to purchase the etrailer Anti-Rattle Hitch Stabilizer for 2" Hitches # e99007 for some additional support. I went ahead and attached a video of the stabilizer to give you an idea about...

  • Replacement Switches for a Bulldog Electric A-Frame Trailer Jack
  • It sounds like there may be a short in your Bulldog jack which could have been caused by excessive moisture from the rain. Also I recommend checking the wiring from the jack to the ground and power sources. The jack grounds through the mounting hardware so you may need to temporarily remove the jack (be sure to support the trailer another way) and sand away any corrosion. Also check for corrosion or damage to the power wire and where it connects to the battery. The light switch itself...

  • I Have Replaced Parts Before With No Issue, Why Is My Superchips Flashpaq F5 Not Working Right Now
  • I would first check to see if there has been an update for your Superchips Flashpaq F5 Performance Tuner - GM - Gas/Diesel, part # SU2845. If so, you should update your software. Once completed, try the tuning process again. According to Superchips, your battery will need slightly more than 12V of power, closer to 12.5V, to make changes to your tune. They recommend you charge your battery, hook it up to a charger, and then try and run the process. The extra power should help complete the...
