Rear axle id Reply #8 – April 19, 2013, 10:28:58 AM 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! Quote Selected

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.Edit:Gabriel 14039http://www.autozone.com/autozone/parts/Gabriel-Steering-Damper/1988-Ford-Mustang/_/N-ihy8aZ8oxi5?itemIdentifier=8593_481907_20203_http://www.amazon.com/Gabriel-14039-Steering-Damper/dp/B001AM5P48 Quote Selected

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! Quote Selected

Still a turd though lolI'm sure you will enjoy the difference don't forget your speedo will be off someMy 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!

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! Quote Selected
