If you drive a Jeep Grand Cherokee and need extra space for gear, a roof rack is a smart choice. Whether it’s for camping, biking, or road trips, a Thule roof rack lets you carry bulky items safely. Many owners worry about installation, but with the right steps, you can fit a Thule rack yourself in about an hour. Here’s a simple, practical guide to help you do it right—plus tips to avoid common mistakes and maximize your new setup.
What You Need Before You Start
Gathering the right tools and materials will save time and prevent frustration. For most Thule racks, you’ll need:
- The Thule roof rack kit (bars, feet, fit kit)
- A tape measure
- Torque wrench or Allen key (usually included)
- Step stool or small ladder
- Clean microfiber cloth
Check your Grand Cherokee’s roof type. Most models have either flush rails, raised rails, or a bare roof. The installation steps are similar, but the fit kit will match your roof style.
Here’s a quick comparison of Grand Cherokee roof styles:
| Roof Type | Features | Compatible Thule Kits |
|---|---|---|
| Flush Rails | Rails sit flat, no gap | Evo Flush Rail, Edge Flush Rail |
| Raised Rails | Gap between rail & roof | Evo Raised Rail, Edge Raised Rail |
| Bare Roof | No rails at all | Evo Clamp, Fit Kit |
Tip: Double-check your Jeep’s year and roof style when buying the rack. Fit kits are not universal.
Step-by-step Thule Roof Rack Installation
Installing your Thule rack is straightforward if you follow each step. Here’s how to do it:
1. Prepare The Roof
Start by washing the roof area where the rack will sit. Use a clean microfiber cloth to remove dirt and dust. This prevents scratches and helps the rack sit evenly.
2. Assemble The Rack
Unpack all Thule parts. Assemble the crossbars with the feet according to the Thule manual. Most racks use a simple slide-and-click system. Make sure each foot is facing the right direction.
3. Position The Feet
Place the assembled rack on the roof. For flush or raised rails, attach the feet onto the rails. For bare roofs, position the feet at the recommended distances.
Use a tape measure for accuracy. The crossbars should be parallel and spaced evenly—usually about 27 to 32 inches apart for most Grand Cherokees. Check your Thule manual for the exact spacing.
4. Attach And Secure
For rail-type roofs, tighten the feet clamps to the rails using the included tool. For bare roofs, fit the rubber pads under the feet and clamp the feet into the door frames.
Apply even pressure as you tighten. Don’t overtighten—this can damage the rails or the rack. Thule recommends specific torque settings, usually 5-6 Nm (Newton-meters). A torque wrench helps get this right.
5. Double-check And Finish
After securing all feet, give each bar a gentle shake. They should feel solid, not loose. Install any end caps or locks included in your kit. These protect the rack and prevent theft.
Wipe down the rack and your roof again to remove fingerprints or smudges.
Common Mistakes To Avoid
Many first-timers make small errors that can affect safety or rack life. Here are some to watch out for:
- Ignoring the fit guide: Thule’s fit guides are specific for a reason. Using the wrong kit can damage your Jeep.
- Incorrect bar spacing: Bars that are too close or far apart make your load unstable.
- Skipping the torque check: Under-tightened racks may loosen at high speeds. Overtightening may dent rails or strip bolts.
- Loading too much weight: The Jeep Grand Cherokee roof is rated for about 150 pounds total (including the rack). Check your manual for the exact number.
Here’s a quick comparison of weight limits:
| Model Year | Roof Load Limit (lbs) | Thule Rack Weight (lbs) | Max Cargo Weight (lbs) |
|---|---|---|---|
| 2014–2021 | 150 | 15–18 | 132–135 |
| 2022–present | 165 | 17–20 | 145–148 |
Insight: Always subtract the rack’s weight from the total roof limit to find how much gear you can safely load.
Tips For A Better Rack Experience
- Check your rack before every trip. Vibrations can loosen bolts.
- Remove the rack when not in use to reduce wind noise and improve fuel economy.
- Use Thule locks for theft protection, especially if you park outdoors.
- In winter, clean under the feet to prevent salt buildup, which can corrode metal parts.
Many Jeep owners forget that an empty rack still affects gas mileage. Tests show a roof rack can reduce your Grand Cherokee’s fuel economy by 5–15%, even when not loaded. So, take off the rack if you don’t need it for a while.
