[Healeys] Rear end noise

My Lempert set is noisy, too, and I've heard from others that have noisy gears. Some gearsets--maybe it's certain ratios?--are noisy. My dad used to be a Ford service rep, and he said the early Mustangs all had noisy rear ends. 

Redline now has a 75W-110 diff oil, which they claim might help cut the noise, without the thickness of a 140. I'm going to give it a try.

I had the Lempert gear set installed in my 1966 BJ8 this year put about 2000 miles on it. 

I have a pretty loud hum at about 35-45 mph………the hum only occurs when accelerating…..when you let off it goes away. 

Can someone tell me what is causing it ? can the new gears be readjusted if that’s the problem? 

Thanks in advance
