No,
Check the torque values and make sure they were not tightened excessively. Assuming all is good there, lube the uniball with triflow and the bushings with the proper lube for that application.
I'm positive the creaking noise is from the uniball, use teflon lube or triflow and spray down the uniball top and bottom and the noise will go away. The noise will come back, just spray again.
yup, I usually turn the wheels to get better access, wipe down the uniballs up top and under with a rag and spray both sides.
