It’s finally come time to install the new 8.8 differential in the #FairmontProject. There were only a couple of snags along the way. For the most part this seemed to go pretty smoothly. Much easier than setting it up.
You can also do this job on the ground with floor jacks and jack stands. I’d recommend 2 floor jacks and a level surface.
I have a LOT of links for this video so I’m going to keep this part of the description short. If you decided to do this job, good luck. Otherwise, thanks for watching!

Who did the welding, Helen Keller?
I'm excited,,,nice work
Cutting oil the best,,,to save on bits
So what if you had modified the brake lines of the differential to land the splice on the passenger side to retain a similar hook-up to the main line like it was stock? Anything I'm not thinking of? Is it bad that there would be unequal length lines to each caliper after the splice? Also, how did the diameter compare of the brake line main that goes through the cabin to the rear disc brake lines? On mine there's a noticeable difference in line diameters of the old (stock Fairmont) drum brake lines and those on my Lincoln Mark VII rear.
use silicone grease on bushings, and fill diff before installing cover while it was on the bench
I got same type of tubular control arms on my 88 Stang . First had square tube now got round tube control arms. couldn't get new bushing for the square tube ones.
WOW! Great self confidence! and what a shop you have and the thickness gauge for the shims was impressive! Good Job!
HOW IN THE FUCKING WORLD CAN YOU NOT TORQ…. ok I'm calm
doesn't royal purp have friction modifier in it already?
Cool vids, my fun is coming next spring. Slowly collecting all the parts. 4th gen parts / LS, into 3rd gen. Zoom Zoom.
Love your videos Eric. So simple and real !!!!!
Hooking up the lower shock bolts first helps a lot, the factory manual actually tells you to leave the shocks connected to change the springs 😉
17:00 fold up 3-4 shop rags, place on pole jack, place pole jack in the nook where the sway bar mount is welded, boom. Just installed those same arms today, worked like a charm, no scratches. May have to draw axle in/out a little but way safer 👌
Why not just weld a cap on those instead of putting drain holes in?
This is me actively making fun of your welds. Ha.
i love the flare tool
Eric, what is that vise, and why the extra fixed jaw?
The fixed jaw on the back side.
steve
Eric you are the best dude!! Great vid!!
As you said , Keep making videos Eric! Thanks
Those solid control arms are why the front mounts break. No provision for articulation.
Wow that rear end is sweet,I`ve never known anyone to invest in a Fairmont.
I drag raced for over 30 years. For 800HP you should have used a 9 inch Ford rear end. That 8.8 is way to weak if it ever hooks up. No c clip eliminator for the axles?. You gonna learn the hard way my friend. You always set up your rear end with the new bearings also. Sell that 8.8 and get a 9 inch. Keep up the video this should be good. Over the years I have seen so many broken axles without c clip eliminator. The car gets wrecked and seen people die from this mistake. For what you paid for parts you could have bought a new 9 inch ready to install. You need a spool and at least 33 spline axles. I have 35 spline in my camaro with a 8.5 rear end. All my stuff is Mark Williams stuff. Never broke any rear end parts in over 30 years. My car weight is 4200 lbs with me in it. Good luck Eric and we all learned these lessons the hard way. Even me.
You live 3 hours drive from Moser Engineering headquarters. Buy some Moser Engineering race parts.
i have that same damned LED light. one would think the manufacture would make it any color but black.
Vacuum pump oil works very well for drilling and and works pretty well for an Assembly lube in my experience
eric loving the… The Fairmont Project…keep it up …ive learned so much from all your videos …thanks man
Wtf..premium membership wtf is that
Eric great work and video. But i have to ask what is the norm as far as price for this whole job minus the upper and lower arm job? Thank looking for more of your videos
What's that blue sprayer thing that use use to clean off parts?
I done this on the floor a little while ago, same process just a lot harder lol
I've been watching your videos for quite some time, and always enjoy them. For some crazy reason, your videos always show up on recommended, and on "reminders"…but I just noticed I never subscribed to your channel! Anyway…proud to be a new sub to your channel as of today. Keep up the great work brother! ðŸ‘ÂÂ🇺🇸ðŸÂ»

Do those new control arms that you used use ball joints? Please answer
I love your videos,and good camera man.
Those look like SVE brand control arms, kinda cheap to be honest I have a set on my 93 Mustang.
pretty sure royal purple already has friction modifier in it
Why did you go with the 8.8 and not the 9 inch.
love the videos eric these butt holes that bitch can eat a quart of used oil lol
