I got a set of Richmond 4.10s installed about a month ago and I have notice that at free way speeds there is a very high shrill 'tone' that comes at light throttle. I dont want to call it whine just yet..

It comes on at specific freeway speeds and I had to get a second opinon that it was even there and I wasnt hearing things. The shop that did the install went for a ride with me and said there was no gear whine and I have been told that Richmond gears just make noise

What do you guys think??

Sounds like whine to me, let guess from 45-70 or so in 5th or sixth gear.

Min only does it at about 62ish and then again somewhere in the uper 70. It doesnt sound like the gear whine that Ive heard befor.

Doesn't sound like a problem to me though. I had the same symptoms, and loved my Richmond gears.

Often it is more of a harmonic whine which is normal. When you get to a certain speed, the sound frequency transmits from the differential. If it gets louder, that may be something, but I will bet you are going to be ok.

Yea it will be ok as long as it doesn't get to load. I like my richmonds to and i don't mind that litlle sound cause its nothing that my exhaust and sterio can't drown out.

From the way you describe it, it doesn't really sound like a problem. kind of hard to tell via the internet though. If it starts to get louder then I'd be concerned

Just put your ear up to the monitor and...

My stock gear was sounding like that after a while. Gears were fine though when we pulled them at 23,000K. Only thing was the nut holding my pinion gear in was pretty loose.

I think its just what 4.10s do. After the first couple WOT passes you put on them they are going to wine a little, doesn't mean you rear is about to go.
