3.73 noise!

2tonestanger · Nov 18, 2006

When i first got my stang it had stock gears in it but i bought some 3.73s from the guy who owned it before me- he said he got them and hadn't installed them yet. After they went in they whined like crazy so i replaced them with a brand new set of ford racing 3.73s and they did not whine... till recently. Anyone else notice that 3.73s wear and whine over time? Do i have to get new gears or what is the problem?

Also I have aftermarket headlights and they constantly gather moisture in them, what can i do about that? Obviously seal them but first how do i get the moisture out?

My 373's have been in for over 100K and no problems... its prolly how someone installed em...

ive heard of people putting thier headlight in the oven on a low temp to unstick the lense from the housing... then clean em out real good and re seal em back together.... but i dont know what you want to set the oven at.. i just cut mine apart with a utility knife...

oh you said aftermarket... meaning that the housing is prolly not the same stuff as fords.... so i wouldnt put em in the oven lol... i would just use a heatgun and a razor blade... and then just RTV seal them back together...

check the pinion for play, you can do this by removing the driveshaft and wiggling the pinion flange up and down if you feel play in it then the bearings are shot. This is caused by improper installation most of the time.

Quality gears shouldn't wine if installed properly.

i agree with svt tech check the pinion for play, becasue a good gear install should not whine with the pinion depth and backlash set correctly

yeah if installed properly no noise should occur

No noise on mine. I have about 30k on mine.

Mine had a slight whine between 45-60 and i think after a couple thousand miles I don't have it anymore. I really haven't heard it that much.
