We had a shload of rain and the streets were flooded with about 8" of water. No I have an annoying squeek/vibration from the front passenger area that only happens when the suspension is moved a little. Flexing the front end doesn't produce the sound until the very last little bit of travel before the car stops moving. Needless to say, I do all city driving so the 25 mph speeds really hit the sweet spot for the squeak/vibration.
I think it may just be the bushings in the suspension, but I've never heard of the bushings needing to be lubricated.
