recently took off my rear rack to get in my brothers shed for repairs and on the weekend noticed water in the bottom near the tailgate where the rear bodymounts are located?

have heard about roofracks somewhere here i think do most people silastic the bars in place as well?

You mean these 100's will take water through the roof racks factory pre-positioned holes in the roof?

What stops the water entry when you don't have a rack? and why the hell do they leak in the 1st place...surely the holes don't go all the way into body (cabin) without a water proof stop????

yes - 100s do take water through the factory installed mounting points. They come with (presumably sealed) bolts in place "filling" the holes.

The holes presumably go into the body without a water proof stop but I've not taken it apart, not looking inside.

I had this problem - when I asked numerous folks told me they had had the problem, and their solution worked. Since then I have had opportunity to help half a dozen others with the news.

Andrew - the vehicle comes from the factory with a soft, plastic waterproof seal over the roof rack mounting flanges - needs to be picked out to do a roof rack install.

Not having seen one from the factory, I've yet to see that - thanks Darian.

Cheers

Happens on the 120 series prados as well. Neighbour across the road has had all his hood lining replaced and front seat due to it leaving water marks, he wasnt a happy camper I can tell you. Toyota had to pull all the screws out and seal up then put back in. Regards steve M

They also crack due to either too rigid a roof rack or too much weight on the rack (s).
Just need a bit more silicon then ;-))

I had this problem too, after Toyota fitted factory roof bars.
Problem also shows up with much worse symptoms if the 100 is parked nose downhill. First thing I knew was the passenger seatbelt was soaking wet. Seems water had pooled in the bottom of the B-pillar and partially covered the retracted belt inside the pillar. On investigation, found water in the front passenger footwell.
Took it back to Toyota who refitted the roof bars after sealing the rack hole threads with Silastic.

I used pipe thread sealer out of a tube as opposed to sikaflex. Plumbers and aircon people use it to seal pipes under pressure so hopefully that works. Not as messy as sikaflex.
