Ring and Pinion gear install: How to install rear end gears. Ford 8.8 inch and other 3.55 4.10 3.73

[@fightthefarleft]

Danny Johnson Thank you. I did 4.10 gears my self on my 03 GT Centennial because of your videos. Much appreciated.

[@dannyjohnsonsgarage]

Very cool! Great job. It’s such a good thing to know and not be dependent on others with. It also assured you took the proper time. Great job!

[@roo-jitsu3449]

Hands down the best video of its kind on the internet

[@Flathead-fb5tk]

Wow, I had never heard of the shims for the caliper. I had my rear end rebuilt with 4.10s and a 31 spline setup. Babied the car for over 1000 miles before trying them out. A few months later I'm getting what sounds like metal on metal grinding from the rear. Definitely rotational and it sounds like it's at wheel speed. Doesn't show it's face till I get up to speed (around 30mph) but once it does, even when I creep to a stop I can hear the grinding, basically sounds like it's hitting at a specific point, not constantly. I'm thinking something in the rear is shot but I'd never heard of spacing the caliper brackets out. Might be worth checking out. Great video though man, thanks!!!!

[@c4llahan]

Really appreciate the video. I’m planning to swap in some 4.10s on my Crown Vic. So straightforward and informative vids like this are great. Btw, I dig the Mach 1.

[@davidw7080]

Good video overall however things to note, You can re use the crush sleeve! despite popular opinion to not, take the old crush sleeve slide it onto a socket that fits the inside diameter. On a hard bench use a hammer and rotate the sleeve while tapping with a decent amount of force around the sleeve to slowly cause it to increase its width, THIS SAVES a lot of grief. Removal of carrier bearings is easy if you have the ability to remove the ring gear (make sure you mark location if re using, not completely necessary but a good practice) use some large cutting pliers to cut the bearing cage and remove the roller bearings. Use of a press and or air hammer + torch (wear eye protection) will remove the race off the carrier. Installing them is also simple the use of a seal driver with old race and a big hammer gets the job done (hit like a man).

[@yannyfrag]

I haven't seen the video yet but you just read my mind. I was going to text you today to see if you could do a video just like this one. I want to take my 4:10 and pit the stock back on or 3:73 am not sure what to do.

[@G_Rapids]

Go 4.10. Much better acceleration, and not much of a hit on MPG. Get a tuner though to correct your speedometer.

[@yannyfrag]

@@G_Rapids my speedometer is perfect, I already have 4:10 on it and it's too much I don't like them I cant hook on 1st or 2nd and I have 315 drag radials. I can't even race a toyota Prius for the dig lol spinning is not winning

[@G_Rapids]

@@yannyfrag If you went from stock gearing to a 4.10 and 315 tires, without re-calibrating your speedometer, it's off. But if you just change out the ring gear you should be fine.

[@jasoncameron34]

@@dannyjohnsonsgarage that's awesome and I'm sure you will take care of the stuff it needs

[@THETOPGLOCK]

Old video but very detailed. Looks like you got away with just using the stock shims in original locations. I’m seeing that a lot especially if you stick with Ford performance gear set.

[@dannyjohnsonsgarage]

Yes, the pinion shim worked great. I remember moving something like .005 from driver to passenger side of the carrier or vise versa

[@genericdude6551]

How do you know which gear ratio is best without experimenting? My understanding is that traction could be an issue if you're using a supercharger.

[@dannyjohnsonsgarage]

There are a lot of factors. Tire size can even be one of them as it will change the overall ratio. A 4.10 in my mach 1 is great for all motor but with enough HP from a supercharger on my cobra and you want to push a slightly harder gear. Even transmission gearing plays a key role. Most transmissions on these cars have a 1:1 ratio for 4th. I found with 4.10s it ended each gear about 10 mph lower than the factory mach 1 3.55s. If the 1/4 mile is your goal and you’ll want to make sure you’re not shifting right before the end of the quarter mile. I will also say though that my mach 1 surprised me how well it pulls in 5th gear. kzbin.info/www/bejne/mKKmqJWvlJqtha8si=4hpqMspkX3nXxGuC

[@bosbear6525]

Will the entire rear end from the Mach 1 directly mount to the Grand Marquis? If so what years...

[@kevinvazquez1585]

Would 3.73 gears of a 2001 mustang fit a 1999 crown Victoria?

[@dannyjohnsonsgarage]

Yes, if they are both from the 8.8” rear end. The housing will not, but the internals will

[@TheDuck8679]

Dumb question, if I weld the spider gears for posi (dirt track car) would I still be able to change the ring and pinion gears out?

[@dannyjohnsonsgarage]

The ring and pinion should still come out if welded as long as they weld inside the diff only as they should. Every turn will screech the tires as you’re probably aware

[@hamper116]

Hey I need some help. My rear end feels really sloppy when going over imperfections on the road, it pulls left or right and I have to be precise with the steering. It’s a 2002 mustang gt, why does it do that. Also I have too much negative toe in the rear, my friend at the alignment shop said that the axle are bent. Please help if you can

[@dannyjohnsonsgarage]

I would look at the bushings on the control arms. If they are worn they could cause both the sloppy feeling and the bad alignment. It’s unlikely the axle is bent, but if so it would be your best option to get a whole new one from. salvage yard and swap it in.

[@dannyjohnsonsgarage]

Swapping in a new housing is pretty easy. Just make sure it’s from another GT kzbin.info/www/bejne/j3TFlqGqiL2La6M

[@oWolf0]

Could I just buy a rear-end that already has 4.10s and save myself this job?

[@dannyjohnsonsgarage]

The Eddie bower edition Ford Explorer came with 4.10s and 31 spline axles, but it’s otherwise hard to find it pre-assembled as an assembly

[@scrap_metal_magic]

Do you have to replace the pinion seal or can you use the old one when replacing gears ?

[@dannyjohnsonsgarage]

If all you are doing is the ring and pinion you could leave it, but as you’ll see in the complete video series for this it’s a good idea to replace the seal if you also redo the races and everything the master bearing kits come with.

[@TheJosephayal]

My 01 stang t45 with 130k original clutch has develped a bearing or whining noise only in 1st and 2d gear (between 3 and 10mph) my rear main seal is pretty bad, any ideas? my car runs perfect

[@dannyjohnsonsgarage]

Cody Koala The clutch issue may be the throwout bearing or some trannsision bearings for those gears going bad. You’ll need to remove the transmission either way. The rear end seal you’ll need to fix before it ruins the wheel bearings and differential bearings kzbin.info/www/bejne/gofWlaqpnZmon8U

Hey Danny, just got 373 gears installed in mine; what break in process do you reccomend to break the gears in?

[@dannyjohnsonsgarage]

Do a few heat cycles gently accelerating to 60, and let the car slow down gradually. Take it for a drive for 20 minutes and let it cool completely. Make sure you have friction modifier. Try not to stay at one constant speed if possible. Some people just go out and beat the heck out of them

[@XxXRage115XxX]

@@dannyjohnsonsgarage ah yes I see, for how many miles do you recommend doing that for? I see anything ranging from 100 to 500 miles on forums , it's hard not to go crazy with them lol

[@dannyjohnsonsgarage]

XxXRage115XxX A few hundred miles. I know there are people who go straight to the track and beat on it

Hey Danny, I've been having a hard time finding some info, i need to rebuild my differential in my 03 cobra, but can't seem to find the kit i need, is there one you recommend or could link me?

[@dannyjohnsonsgarage]

From my understanding, the differential portion is the same as the solid rear axle- just no c clips and you slide the half shafts right out when removed. Here is my video on that (you’ll need a 36mm socket), and I’ll try to get more info, but latemodel restoration should have it all with their master install kit for the 79-14 8.8 kit kzbin.info/www/bejne/aoeoomyIZZVjg5o

@@dannyjohnsonsgarage Thanks! ill check it out, one more question if you could, where can i get a trans mount for these cobras? I tried calling ford, they said it's discontinued, all the shops i've called do not have them, and i can't seem to find any on LMR or AM

[@dannyjohnsonsgarage]

That’s going to be a tough one. I’ve had several people ask and they are hard to find. You might find an aftermarket one or find one on ebay

[@G_Rapids]

@@dannyjohnsonsgarage Maybe ill just build one. It can't be worse than it is now...i have quite the shutter.

You’ll also want to remove the differential for this one in my opinion kzbin.info/www/bejne/marOiKBmo5VrfsU

[@spencerleeb]

Could I swap gears between a Crown Vic and IRS Cobra rear end? I know the rear ends are different but internally would the 8.8 ring and pinion be interchangeable?

[@dannyjohnsonsgarage]

Yes, the ring gear and pinion are interchangeable as a set

[@spencerleeb]

@@dannyjohnsonsgarage Awesome thanks! Opinions on using used ring and pinion?

[@dannyjohnsonsgarage]

@@spencerleeb You may get some gear whine from the old pattern. Some people say they are quieter, so it just depends on how they are set I guess
