Replacing Rear End

[SmileForTheRearView]

So my rear end is growling when I’m on the highway and let off the gas. Shop I talked with said they would just put in a whole new rear end instead of trying to diagnose the part that needs to be replaced.

I have a 15 GT automatic with 3.15 gears though. Should I just buy this from LMR and get the 3.55 gears or does anyone know where I can buy a rear end with the 3.15 gears?

3.55 gears

I don’t track my car and do a good amount of highway driving so I would prefer the 3.15 ratio for MPG

eBay had many good used rear ends from wrecked cars.

yeah I found a few but I was hoping to get a brand new one since mine only has 60K miles. Not too confident in a used one

Do you hear any noises when the car has cooled down some while backing up and making a sharp turn ?
That’s what I experienced and it was the diff clutch plates.

I just bought a 15-17' auto 3.55 geared center section from Ebay myself for $420.00

BTW, these rear ends are NOT very quiet. ESPECIALLY if there's ANY suspension upgrades with harder poly/solid bushings.
