Hoped you might have had it resolved by now. There was more to the grease type and the caliper lube than I mentioned.
Mine actually had the same problem for years, left turn silent, right turn loud. Drove it at 55 for several years due to this because beyond that it got louder. Mine even included an added benefit of pulling to the right.
I won't even include the problems of my own making which came along with learning the system and extreme ADHD, but it all came down to proper bearing grease and caliper lube.
I do not believe improper bearing torque played that large a part in it, as I tore it down time after time, mostly on the right, and did not realize success until all three factors were in place, torque, grease, and caliper lube.
I had gone through an entire can of wheel bearing grease, told the kid at Napa what I needed and he handed me one off the shelf, even though I had looked at the book and told him what it had called for, he said something like "that's what everybody uses on those" so I took it, used it up before I'd figured it all out.
Tore those assemblies apart so many times I can't remember, but the last time, the time when it all came together I had all the necessary ingredients together and well knew how to use them. I'd recently gone to auto parts place and asked for the proper grease(in my case, what the book calls for that model, high temp lithium) but he was having probs locating anything as I kept reminding him the lithium high temp, then saw some higher up and looked at the label, there it was.
I'd also been around the block a few times with the caliper lube and had gotten away from the counter packs and gotten the shop size from off the shelf.
Put it all back together with proper grease, caliper lube on the verge of excessive(but Not sloppy) and torqued with the greatest of care.
The caliper lube got put liberally on anything in the caliper-brake pad-slider/bolt areas where metal touches metal.
And for torquing I simply used my old stand-by's, not really sure which one of these it was but either will do the job if one can grasp the idea of what 35 lbs would be at a foot's distance
One is an old Air force tool and the other a large slip-joint pliers
