rear end rebuild

[marauder410]

getting 4.10 gear installed

got 118,000 on the clock

i kno there gonna wanna do a whole rear end rebuild new seals,bearing

so what exacually is the process, when you say i got my rear end rebuilt

new axles,seals,bearing,gear right?

[ctrlraven]

You may not need new axles.

I would def replace the seals and bearings for sure. The tech can look at your axles and see how they are, you may need new ones you might now.

Unless you need axles they shouldn't be part of a rebuild.


Bearings - pinion, carrier and axle
Clutches (I'd go with carbon fiber clutches)
"S" spring (maybe)
Seals - pinion & axle
Crush collar - for the pinion


Good time to look at the ring and pinion gears. I'd replace them with 4.10's if not already done.

Use a synthetic fluid to refill. Most synthetic fluid doesn't require any additives. 75w-140 is the weight you want.

[marauder410]

ok thanks guys and yea i already have a brand new set of 4.10's and royal purple 75w-140 full synthentic gear fluid

[marauder410]

if they look at the axles and say i dont need to replace them what is a estimated price range you guys think im taking it to woodbine motorsports performance shop

like i said i already have gears and fluid

when i do put the gears in im gonna most definiantly have the rear end rebuild since it bout that time and have 115,000 n car

already had my motor rebuild at 112,000 miles so have bout 4,000 on rebuild jasper motor

also have my trans rebuild at 108,000 miles so have bout 8,000 on a jasper trans

now i need a build rear end and the suspension done

What is the difference of a 4.10 vs. a let's say 3.55 what difference I note from one to other ?

You'll need the FMS-M-4210-A which is the basic install kit for the 4.10 gears and I would replace the axle bearings/seals which are FMS-M-1225-B.

[marauder410]

Carbon clutches M-4700-C

If you wait two weeks my newish axles are coming out for 31's I bought them from Ford probably 15-20 thousand miles ago tops. Also I have a carbon clutch kit coming out with approximately 40 miles on it. Yes, 40 miles. Not sure what shipping would run but figure $250 plus ship if your interested.

[marauder410]

why you taking those axles out and replacin with 31

i was really thinking bout upgrao 31 spines since in doin a rebuild mwell put new upgraded axles too

Yes, the clutch kit contains all the clutches and spacers.

There are rear end rebuild kits that contain all the parts except the axle bearings and seals (no clutches) which you can get at any FLAPS.... just go with the more expensive bearings... the cheap ones will fail on you.

[ctrlraven]

You can get all the parts from summitracing.com as well, that's where I ordered all my parts from.

If you decide to go 31-spline axles you can order new ones from the 2006 and up CVPI which came with them stock. You will also then need a 31-spline carrier aka diff, which if you get a new diff you would want to get the master install kit which comes with the axle seals and the cone/bearings for the new diff.

When I had my 4.10s done I kept my stock 28-spline axles, changed out the axle seal/bearings, bought a new Ford Racing 28-spline diff cause my old one was toast, bought the master install kit which is (FMS-M-4210-C http://www.summitracing.com/parts/FMS-M-4210-C/), threw in the new Ford Racing 4.10 gears and new T/A performance rear diff cover which has a drain plug.

Unless you have bad axles or even soft axles your 28-spline axles are fine, a lot of people upgrade them because down the road they plan on making 400+ rwhp and going to beat the crap out of their rear (burnouts, launching with slicks/drag radials, etc etc).

M-4700-C is ONLY a carrier/diff rebuild kit, you still will need an install kit for the gears. I went through all the options and waited a long time to have my 4.10s put, any questions let me know.

[marauder410]

ok thanks or all the information

so i have

ford racing axle bearing and seals

ford racing axle installation kit (witch are carbon clutches) right

ford racing master ring and pinion installation

ford racing 4.10 gears royal purple full synthentic gear fluid

WHAT ELSE

[marauder410]

i might as well go 31 spline since i plan on doing a supercharger

what is the part number for the ford 31 spline axle

[ctrlraven]

Expect to pay more, with doing the carbon clutches the rear diff is almost being rebuild minus the spider gears in it which COULD need to be replace but wont know until it is taken out and inspected by whoever you are going to have the work done by.

FMS-M-4210-A is the basic ring and pinion gear install kit
FMS-M-1225-B is the axle bearings and seals
M-4700-C is the "cobra" clutch pak which includes the "S" spring

Providing your axles are still good and the spider gears in the diff are still good that should be everything you need since you already have the gears and you'll need at least 4 quarts of 75W140 Royal Purple gear fluid since axle housing holds 3.5-3.75 quarts of fluid.

If you plan on going to 31-spline axles you will need a new 31-spline carrier/diff.

M-4204-F318C is the Ford Racing 31-spline carrier that already has the cobra clutch pak and S spring in it.

If you buy a new carrier then just get this ring and pinion install kit FMS-M-4210-C, it includes the axle bearing/seals and the new carrier bearings which will be needed to install a new carrier. I got this kit when I installed my new carrier and 4.10 gears.

Yes if you want to upgrade to 31-spline setup that will work. You can get the install kit from Sparta or if you choose to from somewhere else but most places will be about $110 shipped so it's really only maybe $10-15 difference between Sparta and some place else.

[marauder410]

thanks so much guys really appriciate all the input and helping me understand everything i need to do a rear end rebuid. Im gonna get all the items needed ready so when summer comes ill be ready and should have enough funds together by then to get it done
