5th Gen 4Runner Sliding Cargo Tray Swap – Install & Parts List

5th Gen 4Runner SR5 Cargo Tray Install – Complete Sliding Cargo Tray Swap

The sliding rear cargo tray for the 4Runner wasn’t something I ever thought I would need let alone want, but here I am using it all the time.

Now there was nothing wrong with the cargo area in the 4Runner at all, it’s plenty spacious and does the job well, but the cargo slide tray does have its perks. Saving my back by using the slideout tray is one of the main perks. Having to jump inside the cargo area to grab something can be a pain sometimes. Having a slide tray allows you to pull out the tray and easily access heavy items. Yes, it works for sitting on as well. And yes, it works for other creature comforts like setting up snack plates while hanging out by the lake and river.

We love the slide tray now and can’t imagine a world where we wouldn’t use it.

Where to find a sliding cargo tray?

If your 4Runner did not come with a sliding tray then you have a couple of options. While you can contact Toyota and buy a tray directly from them, it’s easier and way more cost-effective to find one on Marketplace or from another 4Runner owner looking to get rid of theirs. I see them listed for around $300 – $500 on there and if you source all the parts on your own, they can be upwards of $2,000 with all the included hardware from Toyota. I actually picked this one up from Brenan @Trail4R in exchange for this post because he was getting a new drawer system and had no use for the slide tray any longer. I would recommend finding one on Craiglist, Facebook marketplace, or just hitting a lot of guys up on Instagram.

Step 1. Remove Cargo Tie-Downs

First, we are going to remove your old factory cargo liner. Start by removing the cargo tie-downs closest to the rear seats. There is an access cover you will flip up (flat head screwdriver or pry tools will do the trick) and access and remove the bolts. Once you have both screws and sides removed the entire panel will pop off and be able to be removed.

Step 2. Remove Trim Piece and Weather Stripping

Now make your way to the weatherstripping at the back of the hatch.  Gently remove the weatherstripping from around the plastic trim piece holding your carpet down. Mine was dirty and sticky so this would be a great time to wipe it down and clean it.

Once the weatherstripping is removed grab yourself a flathead and start popping out the plastic rivets that are holding your plastic trim piece down.  These pop out super easily and don’t require much force.  I found out that you do not need to remove the plastic trim piece from the back,  just pry it out enough to be able to unclip the carpeted liner (use the flathead to assist).

Step 3. Remove the Old Floor Liner

Remove the carpet and carpet pad because now you are done with this entire removal step. Now that you have your carpeted liner out and you are looking at bare metal, you might as well take a minute and vacuum this thing. Mine was very dirty and to be honest I’m quite ashamed at how much debris was attached to my liner because I generally find myself to be a clean person.

Step 4. Install New Floor Liner

Let’s start by putting in our new floor liner. The sliding cargo tray floor liner has a raised ‘U shape’ in the middle of the floor. This step is fairly easy and should only take a few minutes. The new liner plops right down into place and only requires a little bit of maneuvering to get it to sit under the sides by the wheel wells.

Next, clip it back under the plastic trim piece (where you unclipped the old liner), pop the rivets back into place and you are good to go.  Carefully put the weatherstripping back into place and make sure it is secure as it is prone to tearing.

Step 5. Install New Tie-Down Brackets

Next, we will go back to where we removed the rear tie-downs and replace the bracket bolted to the floor.  Your old brackets will not work and the new ones will be much larger and have a piece that will come off the side.  Make sure the long angled side points away from the center of the 4Runner and the arrow is pointing towards the front of your Runner. The new brackets will fit in the same spot the old ones did but are directional.  Your natural instinct tells you to complete this step and install the entire new top cargo box, but don’t do that quite yet.

Step 6. Install Track Rails

Now is time to assemble the slide assembly. I like to make sure everything fits before I start to put in bolts and tighten so bear with me here. The two long heavy slides will go on either side of the upside-down U-liner. Make sure to place them with the locking edge side out. (you will know what mean just by looking at it).

Next lay the long track piece with the rollers at the base by the rear of the assembly. There is only one way this fits and you will know it when the holes line up together. Lastly, there is a long thin metal bar that will go at the top of the assembly and this is going to slide over and attach with 2 nuts on either side (4 in total).  Once I tightened these down I started to start bolting everything back down. Do it in this order and I assure you everything will line up perfectly. 2 bolts attach the top to the floor and then 2 bolts on either side at the bottom attach the rolling portion to the long sliding rail assembly.

Step 7. Drill Hole for Slide Assembly

This is the part where I second-guessed myself!  In order for the sliding assembly to attach to the 4Runner at the bottom, you have to drill. Now not all 4Runners are made the same but apparently, they all have a threaded hole in the same spot and we are going to find it. Seriously tho, there is a threaded hold hidden under the floor pan and the only thing in your way is a pesky thin metal sheet.

If everything previously is lined up (which it is) you will have the exact spot where to drill. If you have a step-up drill bit… good for you because you’re going to use it. At this point, a step-up drill bit is worth every penny you have paid for it; if not, then you are going to use a 3/4″ drill bit and slowly step your way from a pilot hole to a 10mm hole.

Seriously… don’t rush this. It will not take long to get through the thin sheet metal of the floor pan and you don’t want to strip the threads because you rushed it.

Celebrate this accomplishment by putting in the final 2 bolts and knowing your sliding cargo tray assembly is secured like no other.

Step 8. Install Rear Storage Box

At this point, I then went back and installed the rest of the top cargo box. Remember the bolts holding down the old tie-downs previously?  You are going to use them again right now. Put the cargo box on and the two bolts will line up and secure everything together.

The cargo box ends up overlapping 2 spots on the cargo tray slide assembly that would otherwise not fit snugly if you had installed the cargo box before this step. I know this because I was eager earlier in the install and had to remove it when I found out I messed up. This probably is one of my favorite parts of the whole thing, to be honest. It’s a super nice spot to put your jumper cables or some tie-downs. Do your own thing with it but extra storage is always appreciated.

Step 9. Install Cargo Tray

Lastly, slide your cargo tray onto the sliding assembly. It is attached by 2 bolts on either side and locks that bad boy into place. Before I secured them I made sure that the locking portion of the tray worked and engaged and disengaged the whole thing. Once I made sure I didn’t mess up, I tightened everything down. There are 2 black carpeted covers that fit over the assembly (mine didn’t come with those so I used a cargo tray liner to cover them)… and you’re done!

Final Thoughts

In conclusion, I absolutely love this thing. It’s not a mod I had originally planned on doing but I’m glad I did it. Would I have bought one from Toyota a paid a fortune to get it? Absolutely not. But would I buy a used one for cheap? You bet.

Toyota states the cargo tray can hold up to 440 pounds while it’s extended. I weigh about 200 pounds and put all my weight on the end of it and so far there are no issues whatsoever. The sliding cargo tray is going to be perfect for spending days at the lake, or just hanging out on the trail.
