Front End Squeeking

[ok89]

Ok well I went offroading last weekend and got the rig all muddy. I used high pressure water to cleant the undercarriage. Now when I go over the wicked speed bumps (2 feet long and 8 inches tall) I hear some relly bad squeeks. It is coming from the front end. So now my questions.
1. could it be the shocks?
2. did i wash all the grease out of some joint?
3. is there mud stuck in a joint?
4. what do you think it is?

Its really annoying so please help.

Well when I do the shock test(pushing down on the corner of the vehicle) it doesnt make the sound so im thinking that it might be the lower control arm?
