I noticed that my V cross members don't have a drain hole, they fill with salt water.
Would I cause any structural weakening if I drilled a small hole at the bottom of each?
My two cents worth. When rinsing at home water will stay in the cross member. No driving after it is parked. Good question as I have wondered that myself. I actuall run water into the crossmember on purpose to get the salt out. If left in it will rot out the metal (aluminum).
I have been running the hose in the ends when I get home.
I went ahead and drilled an 1/8th inch hole in the center of each one, I bet at least a half gallon of water came out.
Thanks for the input guys.
