Front Gears same as Rear Gears / HUM??
So I just put 4.10's in my rear (8.8) and I had ordered my Richmond Gears from Summit. I thought that the front and rear were the same ring and pinion set. But apparently, they aren't. I was also going to replace my bearings and seals and the like. I know that the gear sets are not the same for the front and rear because the bearings don't fit.
BTW, I'm not talking about different ratio's (3.73 vs 4.10), I'm talking about the actual size of the ring and pinion
Do you guys know if they are the same ring and pinion set? and I'm just on crack
How many shims did you guys have to put on your rear pinion? Any suggestions for when I do the front?? I first put (on my rear gears) 2...not enough....then put 3......still not enough.......then put 5 (becuase of the wear pattern, it needed A LOT more), ........crap...too much it doesn't spin. So I now have 4 on there now, with a little hum.
Does the hum ever go away??
Thanks for the input !!

What about the hum?? I heard it will go away, but I don't see how it could go away.

The hum indicates an out of tolerance mesh pattern. It won't go away unless you correct the pattern on the gears. If you've put more than 100 miles on your gearset then you'll be stuck with the hum forever, unless you buy new gears and set up the new set correctly. Its just an indicator of an out of tolerance setup, you could have just gotten a less than true ring gear which will hum as well even if setup perfectly. Either way the noise isn't going away.
As for the pinion not having enough shims.....are you sure you have the pinion preload within its tolerance range, and are you sure the carrier has the proper amount of shims for backlash and the proper carrier bearing preload? If those settings are out of spec its going to throw off your pinion depth.

My buddy and I put the gears in. He has done a ton of 4.10 gears. The tread pattern is almost exact. Thats why I think the hum is still there, its not super perfect.

You gotta start somewhere!! Thats why I had my buddy help me, who is a mechanic. Thanks for the concern though.
