What's a good place to get a new rear end

 

Dem Brazilian butt doctors

 

Sorry, you meant rear axle assemblies. Junk yard is your best bet and have professional shop rebuild. That will be close to new that you'll get.

 

Not new, but "new" to you

It searches local wrecking yards(your Zip Code) for used parts

Use your year
Ford Ranger
Axle Assy Rear(w. housing)
Zip code

Search

It will then ask you
7.5" or 8.8"
9" brakes or 10" brakes
Ratio, 3.45 or 3.73, or 4.10
Limited slip or open

If you don't know what you have then open drivers door and look at the "Build Label"(Safety Standard Certification label) on its back edge, Take a Picture of it, at the bottom you will see AXLE and under it is a two digit Code like 86 or 96 or R6

Look up your code here: https://www.therangerstation.com/tec...ag-door-codes/

1993 thru 2009 use the same width and mounting points for 7.5" or 8.8", so interchangeable
If 2WD then you can use any Ratio you want
9" or 10" brakes don't matter since you will most likely want new brakes anyway, so go for 10"

Limited slip(L/S) is better but will cost more

2010/11 Rangers axles will also work, they have rear disc brakes, so a bit more work and they cost more, but they are much better
