For the life of me I can't seem to find "jcassity's" list of information! I am trying to read the axle information tag and I cannot find the correct codes. I would appreciate it if someone could help me.
Tag reads: V4978
3L45 75 5C18
Thanks!
Looks to me like you have a 7.5" rear w/ 3.45 gears.
x2. must be a turbo bird/cat?
Yea the l stands for limited slip but don't recall a 3.45 gear you sure it's not a 5 .......3.55
Perfect! Yep, it's a limited slip with 3.45 gears from a turbo coupe. That's what I paid for. Thanks!
Did they make 3.45 gears ? I have done a few just did a 3.73 swap for a buddy 7.5
Just never herd of a 3.45
1st generation Rangers had lots of 7.5" rears w/ 3.45's in them......that's where I'm framiliar with them. My fox cars have all had 8.8's.
If my memory serves me right, (just don't ask the wife about that LOL) That's what I had in my 86 TC before the LSC swap.
Right now all I have in my possession is a set of factory Ford Mustang shorty's and this rear axle then I can start working on the interior. Being my car has an AOD transmission I doubt that I will have much wheel hop. I am seriously considering Aerocoupe's suggestion to buy a set of CHE control arms for this axle. I still need to find out who sells the horizontal shocks. Thanks!
I think local parts stores carry, or can bring in, the quad shocks. 4-5 years ago I picked up some from Autozone. I think they were Monroes or Gabriels.

Looks like they are easily available. I'm going outside to start getting this axle cleaned up for installation. I can't wait to see what a difference it will be from my stock 2.73 gear axle to this limited slip 3.45 gear quad shock axle will be like! Thanks!
I put a track lock and 3.73 in my buddy's 96 v6 auto mustang
He had stock 2.73 and the 3.73 woke the turd up ..... Still a turd though lol
I'm sure you will enjoy the difference don't forget your speedo will be off some
My poor car hasn't had a good cleaning in about a year when I started this project, cool thing is the engine compartment is cleaner than the rest of the car for a change. My new rebuilt "87" Mustang HO engine has about 200 miles on it now. I had the front end aligned along with rotation and balance today. I took off most of the garbage off the axle, so now it's about ready to clean up and paint. I'm trying to figure out which "CHE" package I should buy for this axle. I like having the option of being able to raise and lower the rear end. I bought the stiffest springs I could find (cargo on rear) so that I could cut 1/2 - 1 coil off to lower my car, then put 225/(50 or 55)/16 tires on it. An suggestions are appreciated! Thanks!
Just a point!!!
Pull the cover count the teeth and devide. This will accomplish 5 things
1 The rear ratio
2 If it has POSI
3 Change the cruddy oil and gasket and flush out all the particles. There is always some
4 Measure the ring gear for size. Should be a 7.5 and 3.45 ratio by the tag
5 Check the unit for wear and back lash
A 10 dollar gasket is all that is needed with a couple QUARTS of 75-140
Win Win Situation and problem solved !!!
Tom,
That's the fun part of cleaning, I get to open it up. I also take a can of brake cleaner and clean it out. I've noticed that the new gear oil is synthetic now and like you said 75-140w not just 90w.I did notice some oil dripping from the front of the pumpkin yesterday (where the u joint connects). Is there a seal there that will need to be replaced? Thanks for your help!
That's the pinion seal
Early SVOs came with 3.45 ratio.
Ron
Learn somthing new every day lol
I had the axle upside down and laying forward on the ground, so that is probably why it leaked. Thanks!
Pinion seal needs to be replaced. But special procedures are required not to mess up the crush sleeve!!
No 7.5 came with 3.55 final drive ratio as far as i know!
Along with all '83 to '86 Turbo coupes and no doubt some 4cyl Stangs......
every 4 banger stang I've seen was 3.73 locker.
7.5 ratio rear only has 3,45 gears. 8.8 has 3;55. has to do with tooth count on the rear.
The mustang 7.5s also had 3:08s
should have specified...
the closest 3,55 ratio for a 7.5 is 3.45...
has almost every other 8.8 ratio.
Autozone had the Gabriels listed at $24.99 w/3 month warranty, O'reilly auto parts had the Monroes for $27.99 w/lifetime warranty. I bought the Monroes. They also come with shock boots.
LOL every gear ratio has to do with TOOTH COUNT!!!!!!!!!!
