8.8 rear end axle assembly question
Hello Everyone,
Currently I have a 2001 v6 automatic mustang and the 7.5 rear end is about to give out. I have taken to 3 mechanics and they have told me it will need to be replace soon. My friends have told me to upgrade to an 8.8, which I intend to do. Everywhere I search it states its direct swap except for one post where it talks about a flange.
Do I need to order a flange? If so, would it be a 2001 GT flange?
Does the speedometer need to be adjusted? If so, how much is it off by?
Anything else that would be needed for this swap?
Thank you guys for your help, it is greatly appreciated. My knowledge is limited and want to be well inform.
Thanks,
David

8.8 is an excellent choice!
Not sure about the flange. I was under the impression that the driveshaft flange yoke would bolt up to both 7.5 and 8.8 pinion flanges.
Speedometer discrepancy will depend on what gears are in your new axle. I believe your car came with a 3.27 gear ratio, so if you can find an 8.8 with the same ratio, you shouldn't have to calibrate anything.

Why does it need to be replaced soon? 97% of the 99-04 8.8 were 3.27, the Mach 1 had 3.55 and few 99/00 autos had 3.08. You could also rebuild the 7.5 with your choice of gears and a Detroit true trac and have all new parts under the car and not possibly swap someone else's headache in to your car

When I first bought the mustang back in 2012, it came with 20 inch rims. I decided to put 17 inch mustang rims and notice my vehicle was shaking terribly. I found out that the axle was bent so it was changed.The mechanic told me he was unsure if the axle itself was bent. Now its starting to make a lot of noise when it runs, squeaks when i go in reverse and shakes when it runs so I dont know if maybe the rear end is bent. The 3 mechanics i took the car to told me it needed to be replaced.
Do you think its possible to be rebuild? I found a cheap 8.8, it includes disc brakes, struts, springs for 350. Is that a good deal?
Thank you for the info, it is greatly appreciated.
