Are all 8.8 rears the same?
- Thread starter 351 82GT
- Start date
The differential is about the only thing in common with the 8.8 solid axle. There are many different variations that come with different spring perch locations, track width, leaf springs if that's what was used, disc brakes as opposed to drums, additional mounts such as the quad shock or stabilizer bar additions, and so on. So yeah, there are many variations out there. Your best bet is to measure the width of the axle, there's still a chance it could have come from an lx mustang, but all 5.0 stangs had 2 things in common: all had locking differential and a quad shock design to prevent windup problems.

If it's an 8.8 and doesn't have the mounts for the quad shocks, it's not out of a Mustang.
Traction-lok was an option on many different vehicles. If you turn one brake drum and the other turns in the same direction it's traction-lok. If the other drum turns in the opposite direction it's an open diff.
8.8's in trucks and 4x4 4.0V6 rangers got 31 spline axles and coresponding traction-lok (if optioned). Cars got 28 spline axles. Crown Vic's probably have 31 spline axles too (especially cop cars I'm sure).
Are you certain? I was strongly under the impression that after the 85' model year not only was the 8.8 offered, but trac-lok was standard because it's a necesary saftey device for that kind of power - correct me if i'm wrong someone.....tjm73 said:
On another note, only the fx4 ranger has the 31 spline axles, all others came with the 28 spline (including all 4.0-based 4x4's) as well as many other vehicles.
Also, you don't need to take the drum off to rotate the assembly, the drum is mounted to the axle, therefore it turns with the axle and the wheels as well. It should spin freely.
my car has an 8.8 and i can only get 1 wheel to spin.
i saw the 5.0 that my step dad pulled it from. it was an 89 or 90 (had mass air) and was white with blue interior. i think thats the one he pulled it from. It IS an 8.8 ford rear. whats inside it, i dont know.... you will when you open it. i even included the stock control arms/sway bar/ brake cables....and lug nuts

I have nothing productive to add!
ALL (every single one) V8 Mustangs that have an 8.8 have a Trac-Lok. It is not an option, nor was it. It is standard. That's the way they all come (came).

If that 8.8 does not have quad shock mounts -- it is probably not from a fox body, and you will probably want to get your money back. There's no telling what it is.

Nope...I looked for one.
All I know is that this rear has no quad shock mounts and has the smaller .69 swaybar as opposed to the later .79 swaybar
The lower control arms have a large oval shaped bushing as opposed to the round style.
No disrespect N8miller , but that's not a 5.0 rear...it can't be.
It's an 8.8 rear but I don't know what it's out of.
You said you "thought" your step-dad got it from an '89-90 5.0.
Ask him and see what he says

thats straight from your email. you wanted a 8.8 rear....i delivered. it doesnt say, 'hey, i want a trac-lok posi' or 'it has to have 31 spline axles'..... you simply put you wanted a 8.8 rear.....and you got one.
im not trying to start anything, but you asked for it, i delivered..... end of story.
N8Miller said:
Again..no disrespect but most people would assume someone would want an 8.8 trac-loc rear...especially if they knew it was going under a worked 351 powered mustang...I could be wrong though.
Anyway....it's my fault.. I should have checked to make sure it's what I wanted before any money exchanged hands.

Claim what you want, but I saw it on the window sticker and I drove it and it was not a traction-lok. I remember quite clearly because I was shocked it was not a traction-lok car. It was a 2.73 open diff car. It was brand new on the dealers sales lot. I know what I saw and I know what I drove.
I don't remember what exactly I asked in the email but that's pretty much what I asked for. I just thought that since he knew I had an '82GT mustang with a worked 351w that he would assume I would want a trac-loc rear.
I don't know.....I got the drums off just now and it is an open differential.
What size are the rear brakes on the '87-93 mustangs because this thing has 9" drums.
I'm not sure if I am going to keep it or not yet. I might have to eat $150 I spent on this. I know where there is another 8.8 rear thatIS a trac-loc rear from a mustang. I have to think about this now.
