What would you do

[98mustanggtkid]

Hey all,

Its been a while since I have posted anything. Now on to the Car stuff, on my Mustang the Rear End Bearings are whining pretty bad so my question is, if you have to replace the bearings would you just build the rear end while everything is out or would you just do a rebuild. My plan is to eventually have a quick street/strip car and I figure having a built rear end couldnt hurt any help would be great

Thanks
Chris :wave:

i had the same problem. completely rebuilt the entire thing. the only thing left stock was the axle housing.

it honestly depends on your wallet. you can do a simple rebuild if you are on a budget, or thrown in a set of gears for a couple hundred bucks. if you are rolling in the cash, fully-build it while you're there.

 

[98mustanggtkid]

Im not Rolling in cash but I have been saving to do this incase I decided on the build, I was thinking same thing you did, just keep the housing, new axles, new Diff, new bearings, Stronger Diff cover, dont know if I would need a new Ring and Pinion there is a 3:73 in there now which the previous owner installed is there anything else I would need or so you have a list of the things you bought

 

[MustangChris]

cost me $2,100.00 (if i remember correctly. that was 3 or 4 years ago) to buy all the parts and professional install.

i waited to install the diffy cover tho. kept the stock one for quite a while. i can look up my recipt tomorrow for you.


SVO Gears
Moser 31 spline axles
Eaton Posi diffy
fluid + additive
bearings

eventually i got the axle girdle.

 

[98mustanggtkid]

ok if you could that would be great, and ya I was Figuring it being about $1700-$2000 with all the parts and having them installed professionally What are SVO gears? and do they differ from the Motive gears in any way?

 

[MustangChris]

SVO is the brand. motive makes a good product (from what ive read on the interwebz forums)

 

[98mustanggtkid]

ahh on, ya I have read alot about Motive and My buddy has them in his cobra

you don't need to build it. just rebuild, and stuff some 28 spline moser axles in there and you'll be cake.They are 30% stronger then stock. If you want to be a hero, then yea get the girdle, bad boy 31 spline carrier and some 31 spline axles. Honestly though for what you may be doing, its a waste of money. Look at what your trying to do with the car. I have a stock rear end to the max with stock axles and slicks and mines still together. So don't take a chance of torching it after you rebuild it and just get some 28's and some quality seals and bearings and you'll be fine.

 

[98mustanggtkid]

I Guess I just want to be sure nothing will break I wasnt sure if i would go with the 31 Spline axles but I did want a Posi Rear end and make sure I get the Traction I want

 

[duff daddy]

is it a 31 spline or 28 set up?

 

[98mustanggtkid]

28

 

[98mustanggtkid]

here was my plan
3:73 ( which is in there now dont know if I need to replaced it or not)
28 Spline hardened axles
Detroit Locker 28 Spline Diff
Bearings
Rear Girdle

 

[MustangChris]

good point duffy...

if you arent going to see 500 HP, just rebuild it.

i spoke with a guy at the track and he was running the eaton 31 spline diffy and it failed at ~750 RWHP.

 

[98mustanggtkid]

hmm

Dint even bother with the girdle, unless you want to look cool, you may never use the car as that girdle will really gain what its meant to do.

 

[98mustanggtkid]

ok

 

[MustangChris]

+1 the girlde is actually a pain in the a**.... my gasket leaks, the drain plug leaks, you have to TQ the bolts to like, 4 ft pounds (i dont own a TQ wrench that goes that low, and my local sears doesnt sell one either. lol) plus to open the fill plug is a pain as well.

all these things are magnified when you lower the car as well.

 

[98mustanggtkid]

Hmm, well the car is lowered already actually whats what I did Last year was full suspension upgrade

Just put a normal cover on it and call it a day. Its like the people who DD their car and dont use it for anything track wise and have over kill suspension upgrades or who have 31 splines with an auburn in there who never see a strip... Waste of money

 

[98mustanggtkid]

Ya I get that, it has seen some Track time so its not like I wont use it there but mostly street just fucking with people but i figure While i was in there I would upgrade some stuff
