I had my 4.10 gears installed today and all I can really say is wow. Through researching what to get, I had read alot of the arguments for and against doing 4.10s and I'm here to say, 4.10 are def the way to go, lol, just awesomely fun...

 

Glad you like them.

 

I just put 200 miles on mine since I had my 4.10s installed and I have a slight whine around 45 mph+

 

Awesome, congrats.

 

Hmm... I might try to record the sound my car is making at ~45mph. Its definately a whine when I give it alittle gas...I bought the car used so don't know if new gears where put in

 

Nice.. I want some 4.10's....

 

I haven't noticed a whine and I was definitely listening for any kind of abnormal sound. I picked up the car around 5pm and drove around til 7:30ish, running errands, windows down and stereo turned off. Nothing usual so far, crossing my fingers lol...

 

+1

 

Hey machnjo, did you do anything else to the rear besides the gears?

 

Nope, I just wanted the car to be a little more fun to drive.

 

I have a very slight whine only from 40-50mph. Still I love them and wouldn't chage them for anything.

 

Mine do the same thing at the same speed. I think it is normal.

 

mine have the whine at 45-50mph aswell,normal?

 

its normal with motives i take it. i have the same whine from 45-50 decel is worse though. o well

 

Mine are FRPP, I've heard that it's just because the gears have a pretty straight cut.

 

Can't wait to get mine in. Damn holidays will slow me down. I'm getting the control arms in next week.

 

Mine are FRPP gears as well, and still no whining yet.

 

my old roommate had FRPP 373's installed by the same guy that did mine and his never made a noise. my gears just like to make noise.
