Is it normal for gears to make a grinding/ noise while coasting no gas/no brake and on deceleration/ coming to a stop? is this the normal breaking in noise/s, backlash= .085 pinion preload= 20in lb (new bearings) wear pattern looked about right.

it has all new bearing/ races/ shims new gears.

any help would be helpful:nice:
 
My rear didn't make even the slightest sound when I had it rebuilt. I think most people are gonna say stop driving it immediately and check all of your measurements. I think I remember reading that incorrect backlash will cause noise, but I'm sure someone more knowledgable will post soon.

If the backlash is really .085", that's your problem. Depending what source you use, it should be between like .006"-.011". Now, if you have it set at .0085", that's not it. Only other thing I can think of is if the ring gear is not true to the carrier, or the ring gear bolts didn't get torqued evenly. Good luck, hope you figure it out!

I ran into some noise on the first one I changed. Brand of gears was my problem so I ended up going back with the FRPP brand.

I'm gonna go out on a limb and say that you're noisy gears were Richmond's?

I've got Richmond 4.10's and they whine on deceleration...always have
