converted a/c to R134a and have problems....

i just converted the ac to R134a. i did the standerd prosedure, evacuate, vacume, oil charge(2oz),and refrigerent charge(about 2 3/4 cans). it works well at about 50 degrees out the vent. but when the system gets cold enough the recever/drier starts to shake and vibrate. i dont know what is making it do this.

if anyone has any ac experiense with 7s tell me what i did wrong!!

I am no A/C tech, but it sounds like you have moisture in the system
