Thule Complete Roof System for Volkswagen Installation

Video Transcript for Thule Complete Roof System for Volkswagen Installation

The roof of your vehicle is a great place for extra cargo, bikes, kayaks and more. Many vehicles come with factory installed racks but if yours did not it does not mean you have to miss out on the fun. Thule believes this as well and has designed after market racks for many different vehicles. Our video here shows how to install the rack on a VW Jetta and provides a better idea on what is required no matter what type of vehicle you have. It is time to get your car, van, SUV, truck decked out and start getting yourself out there!

Essentially this kit consists of three pieces. First you have your crossbar here, next is the aero-foot which connects the car and the crossbar, and finally the fit kit. The fit kit converts the aero-foot to match the type of vehicle you are using whether it be the Volkswagen we have here or your Ford pickup. Now we will show you how these components fit together, first off you want to take the fit kit foot and put that on the bottom of the aero-foot which has a little peg to help you line up everything. It simply fits together by press fit. Now we can put our aero-foot onto our bar. First we need to pull this cap off, and then we will just slide it onto the bar. This part here has to be pulled out to keep it as loose as possible. Now we will just slide it on, once you have it put on the bar the way you want it, this part needs to be pushed back in by squeezing these two together.

Next we need to install the rest of our fit kit, that sits in like so, then you re-install the bolt. We will leave it like so because we need it loose to install onto our vehicle. Now we will put our cap back on the bar. Now that we have it assembled, we will go ahead and install it on our car. Depending on the application you catch the roof edge or below the seal like this one does. In our case we are going to have to peel this back and our pad will sit about right here and the fit kit will grab one of these screws hanging out from the roof here. We will install it now, it is a good idea to have someone stand on the other side to catch it and make sure it does not scratch up the paint. Just work it into place sometimes the seal comes loose a little bit too. Now it needs to catch in there and we need to repeat for the other side. At this point it is just a simple process of tightening it up. We will clamp everything into place and you might want to turn a couple of times and give a few more turns because every time you tighten it down it brings it toward you a little bit. Once you get it tight the way you want it, the lever itself snaps into place and locks. Now we will install the front half of it again same thing applies, it is just on the front. There you have it the install is complete, it is a reasonably easy install that may take a couple of extra hands. Those are the basics of all the Thule roof racks whether it is on a car truck or SUV, it is the same components that just vary in size and the fit kit for the particular vehicle.

  • Parts Needed to Install a Roof Rack System on the Roof and Camper Shell of a 2006 Toyota Tundra
  • Since you are not adverse to drilling your vehicle roof and your camper shell I would recommend going with a Thule Podium Roof Mounted Foot Pack. You can use the square load bars, # THLB58, with the # TH460 Foot Pack or the Rapid Aero Load Bars, # THARB60, with the # TH460R Foot Pack. To mount the foot packs to the sheet metal roof on your 2006 Toyota Tundra you will need the Thule direct mount system # THKIT3114, which does require drilling into the roof of your vehicle.

  • Installing a Box on a 2012 Toyota Sequoia to Support a Roof Top Tent
  • If you are wanting to remove the factory side rails that run front to back on your 2012 Toyota Sequoia, I do not recommend doing so. These rails were meant to be permanently installed on your vehicle and should not be removed. These rails are bolted and sealed to the roof and water could leak into the vehicle if they are removed and other damage could occur such as denting and scratching on the roof. If you are wanting to remove the crossbars that run from side to side and attach to the side

For a Whispbar system you will need the following parts: Whispbar Flush Bar Roof Rack, # WB-S11 Rain Gutter Fit Kit, # WB-K324 The only issue is that with the available roof racks, the crossbar spread is so close, at most 20 inches wide, that there are not a lot of accessories

  • Roof Rack Recommendation for a 1995 Volvo 960 Wagon Without Factory Roof Rack
  • Since you say your 1995 Volvo 960 Wagon did not come with a roof rack, I assume it has a bare roof with no side rails.

I have attached a generic photo showing the difference between a bare roof and factory side rails. I have attached a link to all of the roof rack options available for your 960 wagon with a bare roof. Of the available options, I would recommend the Thule

The LB are very well built and sturdy. My set up with the bars, feet, and two sidearm bike holders is quite heavy. It is difficult to lift the whole thing off the top of my truck cap by myself. I would have considered the aero bars had I thought weight was going to be an issue. At least I think they are lighter. Overall very happy with my setup. Etrailer was excellent, great prices, quick and efficient service. 12336

The roof rack I ordered for my husband was what he wanted for Christmas. He wanted to mount fishing pole holders on the crossbars so when he goes fishing with his buddies he does not have to stuff his poles inside his Jeep Rubicon. I really don't understand why he needed them, but this is what he wanted, the old saying of needing and wanting. He was mounting them yesterday to make sure they fit, he was so happy, now we will have to wait till we go up to our summer home in Utah to use them. I also ordered a pole holder from Cabella's which mounts on the bar, it looks real good.29178
