This "Swap Solutions" series of Wiki articles is intended to help the
 +
customizer, swapper, shade-tree mechanic or junkyard crawler.
 +
 
 +
The idea is this: when you pull an axle, engine, tranny, driveshaft,
 +
bearing, or ANYTHING from your car, measure the heck out of it.
 +
 
 +
Countless times I've found myself wishing I had a source to know if
 +
this axle will fit that car, how much that ISB Cummins engine weighs
 +
or if a driveshaft already exists that fits my custom install instead
 +
of paying to have one fabricated.
 +
 
 +
This article is for Rear Axles. The basic idea is so that when
 +
shopping for a 9" Ford to put under a custom-chassis, the user can
 +
scroll through and review a listing of axles that will fit (or come
 +
close) and possibly avoid headaches.
 +
 
 +
Using the formatting below, start adding info. You can't add too much
 +
information. Make sure you give the application(s), year(s) and any
 +
possible tidbits you can. If someone can format this better than I
 +
can, please do, but basically use your codes to make columns for the
 +
following characteristics.
 +
 
 +
#Axle family (like GM 8.5 ten bolt, or Dana 44)
 +
#Application. What year, what vehicle, and any determining factor.
 +
For instance, if I want to find the same 12-bolt you described, it
 +
might be helpful in finding it to know that yours was found in a
 +
station wagon with a big block. Even if you only know YOUR axle's year
 +
it will help.
 +
#Type of brake, disk or drum and their diameter * Or if you will be
 +
able to use your factory brakes, if you like.
 +
#Type of suspension, coil or leaf, trailing arm or torque arm, etc. *
 +
Factory 9" housings do not have a torque arm, although an aftermarket
 +
one can.
 +
#Width from wheel mount to wheel mount
 +
#Width between spring perches, center to center (for leaf axles)
 +
#Width between backing plates
 +
#Width between shock mounts, center to center
 +
#Weight (and note if its with or without brakes)
 +
#Notes for additional information
 +
#Add columns as needed.
 +
 
 +
Pretty much if you are to swap a stronger rear end in to your car,
 +
you are probably looking at a Ford 9", GM 12 bolt, or Dana 60 (maybe
 +
44?).
 +
 
 +
The main item is what will it take to make your new rear fit? For
 +
example, If you want to swap a junkyard 9" in a 99 SS Camaro, the
 +
width of the housing would need adjustment, weld on the suspension
 +
control arm brackets, coil spring brackets, shock brackets. Special
 +
length axles are needed if the housing is narrowed.
 +
 
 +
Brackets for factory brake backing plates to use factory style
 +
brakes. Torque arm bracket (or go with ladder bars) and some people
 +
want to keep the Anti-Lock-Brakes. If you want to do that, you have to
 +
have a special diff carrier, and you have to drill a hole in the
 +
housing to mount the sensor to read the reluctor ring.
 +
 
 +
Your drive shaft yoke might be the same, but it might be different,
 +
so that is another thing that will attention. Most of the time you
 +
will need you will need a new driveshaft.
 +
 
 +
Once completed, a rear differential swap will have been completely
 +
worth it.
