Thank you for this. I did a previous repair and sealed the rack bolt holes and retaining clips but never knew I had to silicone the seam. So thanks again for this. Cheers
Take care of it...mine was neglected by the previous owner,both A pillars are destroyed, the floors has been rusting fron inside the pillars the roof leak was folowing the seam and destroyed a foot of structure behind the airbags....a nigthmare....1 month later , getting closer to fixing it...prevention would have helped 😂
im having the exact problem right now, i thought i fixed it like 10 times already, but this time i got fed up and removed the entire headliner. i also thought its from the bolt holes. ill have a look at the entire seam to check that like you were saying. i put some seam sealer on some of it already, but i may have todo the entire thing like you showed. any other advice you can offer?
yes make sure you clean the outer edge well... I used a wire brush wheel attached to my cordless drill.. use clear 100% silicone and allow it to dry 24hrs before full assembly
Good to know whats in store for 5th gen 4runners as they age... especially for peeps that overload the roof w aftermarket racks/tents w 400-600lbs on top sleeping people lol.
Silicone goes on the outside not the inside. if you seal it on the inside it will just work its way around it. Need to do it like a roof on a house with overlapping protection so the water always is directed out and away.
if you paid attention I did silicone the entire exterior drip rail after cleaning the area 1st. then I also sealed the interior edges.. Zero leaks since.. but thanks for the comment..
@@dclarke2814 I did but just trying to help anyone else who has the same problem. Because like at the beginning where you had siliconed around the inside of the roof bracket. If it was leaking there all that's going to do is push it several inches down the road and it'll leak there. So much easier to use the structure of the car and other items like a house.
@@dclarke2814 because from the top of the house to the bottom of the house everything is overlapping to keep the water going away from the inside of the house because as we all know there's lots of things in a house that will not tolerate water. I get it you didn't know any better but at the same time who else is going to watch your video and then slather silicone on the inside of their roof of their FJ thinking that it's helping.
First, thanks for the video. Have the same issue. Second, how do I remove the strips? Are they just sitting there under the roof rack mounts? Glue? Will they bend or break? Do I pry them up? Are they metal? Thanks for any and all info!
G’day from down under! How did you manage to spread the silicone so evenly? Im looking at using Sikaflex, however, it’s quite thick and not runny, so tricky to apply.
What were your tell-tale clues it was leaking ? I have a dampness sometimes after it rains on the floor mat that I can't figure out where it is coming from.
I had watermarks on the headliner just above the A pillar. I'd say pull the kick panels & a pillars then look for dried watermarks.. if u cant find any. pull the seats out an have someone DRENCH the fj while u crawl around to find the water..... sounds silly but it works
arcadebrat I used the same molding.. but I cleaned it as well... it doesn't seem to stop the water.. but more designed as a trim.... the "seam sealer" is what failed.. it's an adhesive/ gasket type materiel applied during manufacturing to bond the 2 pieces as well as male it water tight.. as u can clearly see pinch weld points up & dn the channel... my thought is over time the suns heat caused expansion & contraction which led to it's failure
actually I did.... i used a wire brush wheel to clean the area as well as mineral spirits. But seeing as I was not about to repaint the entire roof. I didn't strip down to bare metal...
something I left out.. let the silicone cure at least an hr before putting the drain rail covers back on.. after 1hr it will be dry to the touch. if possible let it cure 24hrs before exposure to water..
Shibumi1 Well I'm hoping that the newer models have been improved because I'm sure they got word of this problem and have made the necessary improvements.
Greg Wallace well it was the seams sealer that failed.. its pretty universal stuff.. I'm surprised it failed so badly (on both sides)..but silicone did the trick...
Greg Wallace well my mom owns a 14' an no issues so far.. I literally just purchased my 2nd 07 yesterday... believe me I'm looking at that 1st. (regardless of condition I'm going over it with silicone) Oz of prevention as it were

I will be tackling this job this weekend. I just bought an 07 FJ and have the same issue I suspect. Thanks for the great video. 👍
how did your roof turn out?
Thank you for this, I have an 07 and haven't had the problem "yet" but when I do, I'll know right where to go and what to do.
How well has this repair lasted? I have an 07 with the EXACT same issue.
Thank you for the video. My 2014 is starting to leak.

Glad to help... Sucks that people don't take better care of their FJs!!!

Glad to help.... inexpensive fix... just a lil time consuming..but my results have lasted yrs so far

yes they are pressed in.. not too tightly..
I use a plastic pry. I bought a full set on Amazon for $15 they come in handy for nearly everything
@@dclarke2814 Alright, thanks for the info. Just didn't wanna break anything! 😃
G’day from down under! How did you manage to spread the silicone so evenly? Im looking at using Sikaflex, however, it’s quite thick and not runny, so tricky to apply.
Should have used a product called seam sealer..made for that application
well the original seam sealer failed... so why would I use it again? its been years now an the silicone is holding up 100%....
Very helpful!!! Thanks
Just noticed on my 2007 drivers side above my door
Is this an 07 problem or does this happen to every FJ ? ....I have a 2010 with 250,000 km & I've never had this .
Just bring back the gutter roof, never had a problem!
What were your tell-tale clues it was leaking ? I have a dampness sometimes after it rains on the floor mat that I can't figure out where it is coming from.

How long did it take to do this?
Did you use the same old molding or did you have to buy new molding? Was the molding easy to remove and how did you remove it? Thanks.
arcadebrat I used the same molding.. but I cleaned it as well... it doesn't seem to stop the water.. but more designed as a trim.... the "seam sealer" is what failed.. it's an adhesive/ gasket type materiel applied during manufacturing to bond the 2 pieces as well as male it water tight.. as u can clearly see pinch weld points up & dn the channel... my thought is over time the suns heat caused expansion & contraction which led to it's failure
You didn’t clean the metal before adding silicone?!
actually I did.... i used a wire brush wheel to clean the area as well as mineral spirits. But seeing as I was not about to repaint the entire roof. I didn't strip down to bare metal...
What type of silicon did you use?
GE Silicone II clear 100% silicone rubber sealant (not caulk after awhile caulk will crack)
something I left out.. let the silicone cure at least an hr before putting the drain rail covers back on.. after 1hr it will be dry to the touch. if possible let it cure 24hrs before exposure to water..
what year is your FJ?
Greg Wallace 2007.. but i assume they're all the same structures
Shibumi1 Well I'm hoping that the newer models have been improved because I'm sure they got word of this problem and have made the necessary improvements.
Greg Wallace well it was the seams sealer that failed.. its pretty universal stuff.. I'm surprised it failed so badly (on both sides)..but silicone did the trick...
As long as you fixed what you need to fix, that's all that matters. I just hope I do not have to do the same with my 14
Greg Wallace well my mom owns a 14' an no issues so far.. I literally just purchased my 2nd 07 yesterday... believe me I'm looking at that 1st. (regardless of condition I'm going over it with silicone) Oz of prevention as it were
