You were informed wrong. Motive brand 4.30’s are hit or miss for slight whine. Even that dates back quite some and I could only imagine it has been addressed.
4.10’s are cake. I did my own with the proper tools except for an inch pound torque wrench for setting the pinion. However I use a solid spacer so no crush washer to worry about. It’s been quiet as can be for 18,000 miles.
