I have a 07 GT 5 spd with Breenspeed tune/BBK, CAI Pypes H pipe, Mac Boomtubes, and really want to finish it off with the 4.10s. My question is, I live in a small town around Memphis,Tn and I just have no clue who would be able to do this for me. I cannot do it, don't know **** about gears. I know I do have the 3.31 gears and can't stand missing out on the fun fron the 4.10s. How do I know if I can trust the mechanic to put them in for me? If I buy the 4.10s, What else do I need to purchase? I want to make sure when I drop it off with mechanic he has what he needs to swap them. My car has 38,000 miles on it now, so I'm thinking all I need are the 4.10s and mechanic to put them in?

 

Have you checked with your local Ford dealer service dept?

 

I'm also sure if you post your location, people around the area will have great advice

 

Well, I have an H pipe on my car and worried it will void my warranty if they see what i've done.

 

PM Eaglestroker. He's a good guy and is from the Memphis area and he could probably recommend a mechanic to you.

 

Your warranty can NOT be voided if an aftermarket part is installed. However, Ford can simply choose not to honor a claim if your modification(s) cause(s) a failure with a factory part. It must be a direct cause/effect relationship, as provided for in the Moss-Magnuson consumer protection legislation.

Ford dealers are an excellent place to have a gear swap done. Most have a technician that specializes in differential repairs, and they'll have all the correct parts on hand that you might forget to provide (crush sleeve, bearings, shims, traction-lok additive, fluids, etc.). I've had our Ford dealership do several gears swaps for me and they are always done right the first time and they only cost a tad bit more than an independent shop would charge, in most cases.

 

Shoot me a PM, ill also link you to our local car clubs and give you my preferences in tuners as well as some of the local scene, need to come out to the blue plate cruise tomorrow night, see anywhere from 100-300 cars depending on the weather!
