anyone out there with 4.56 gears with noise . mine were installed at a chrysler dealer which i work at and good bit of noise but what a difference in accel wow!!!!!!!

 

What kind of noise?

Grinding?

Whining?

On accel or decel or both?

Most rear noise is improper ring/pinion lash, or an issue with carrier bearings.

 

ON ACCEL AND DECEL, WAS TOLD ITS NORMAL WITH THESE GEARS. AND TO ANSWER IT IS A WHINNING NOISE I AM HEARING

 

I guess the whinning is really loud since you have to yell out what you are writing.

 

Whining is more noticable when gears are a striaghter cut (angle of the gear teeth) then stock gears. The straighter cut makes them stronger, but noisier.

How noisey, or "normal" your is depends on the extent of noise.

 

How much did it cost you to have them installed

 

So do 4.10's on mega cabs whine as you drive them off the lot?

 

sorry bout the caps my computer at work requires cap letters. i foorget some times. as far as cost nothing i work at a dealership my lead tech did it for me. i understand about the cuts, just wondering if anyone else out there had any noise.

 

4.10 to 1 gears should be quiet off the lot. In my personal experience anything steeper than 4.30 tend to whine a bit for the reasons stated above. most gears in the 4.30 and up range are strait cut, some super heavy duty trannys have strait cut gears and tend to whine also. Listen to a NASCAR sometime.

 

The 4.30:1's in my Demon whine a bit when not accellerating, but the wear patern on them is perfect.
