Ok so this is my THIRD time going back to the shop to have my whine go away from the new 4.10's that were installed. I bought brand new ones again ( the shop is reimbursing me ) i got the ones from American Muscle.com the FRPP ones. They installed the first set at .008 and they whined so i went back and they set it tighter to .004 and now its unbearable. I am driving down to North Carolina for the 4th of July and i need to know what I need to tell this guy to set my car at and everything. Please Help me out!

 

I do believe factory should be .015

Correct me if i'm wrong....

Why doesnt this guy have the know-how and resources to look this up himself?

 

It says you're in CT. Who's doing your install? The guy sounds like a ****ing retard.

 

Make sure whoever is doing it pays attention to the pinion bearing preload specs for either a new or used bearing.

Torque Specs SAE
Pinion Bearing Pre-load, used 8-14 in/lbs.
Pinion Bearing Pre-load, new 16-29 in/lbs.
Ring gear bolts 70-85 ft/lbs. (in stages)
Main bearing bolts 70-85 ft/lbs.
Pinion shaft lock bolt 15-30 ft/lbs.
Driveshaft bolts 80-90 ft/lbs.
Gear Setup
Backlash .008-.015 “

Mine is at .015 and not a single noise.

 

theres more to setting up a set of gears than just backlash , does the idiot have the pinion depth right ?....is the contact pattern right ?....you better get to someone that knows what they're doin !!....and now that you been driving for so long with them set up wrong and whinning like crazy , theres a chance that even when they're right they still may whine....you better get away , and STAY AWAY from this person

 

find another shop, and have them pay you back since their going to for the gears anyways.

 

I'm definitely not going back to this guy ever again, but while doing it for free supplying the fluids and everything I'm gonna go with this one last time. I am from CT so if there is anyone who works on Mustangs and won't kill me for any thing like I've been with these guys PLEASE let me know i would be more than happy to give you my business. Thanks again guys.

 

once a set wines 90% of the time they will always wine cause the gears will actually
machine themselves in the improper setting which will stay and cause wining with whatever setting they do to them
you most likely need a new set of gears i would make the guy that installed them buy you a new set cause he f'ed up

 

That is not true. My gears whined for 4 years do to letting somone else work on my car other then me. Once I installed the new aburn with the same gears there isn't a single sound.
