It's my work truck so I'm not positive on the details but here goes. I believe it's a 2001 f-350 supercab (1 1/2 doors). Even if I slam the back door the two don't close tight anymore and you can see air between them from inside the truck. Is there a way to adjust the latches or something to get them tight again? The whistling noise is driving me nuts!!
Thanks for any help guys.

 

I don't think there's any adjustment on those doors. You might need new door seals.

 

I'm not sure I'm reading this right. Are you saying the rear doors close good but the fronts don't seal all the way? My 02 F250 s/c had this problem. The strikers for the front door is bolted on the rear rear door and is not adjustable....but you can make it adjustable. You unbolt the striker off the rear door and you will see it uses counter sunk bolts. You just drill out the counter sink, go buy regular bolts and washers and you will be able to adjust your striker in so your front door closes up tighter. I hope that helps. Good luck.

 

That sounds like it should work, now i just need some nicer weather so I can make a mess.
Thanks
