Joined the broken Rear end Club
 

well the noise i have been hearing from the rear end on accelleration has finally been solved. my axel tubes are slightly bent, the carrier is bent causing runoff on the gears. a whopping 13 degrees at max. because of all of that the gears themselves have an abnormal wear pattern.


I need a new rear end.

so i priced everything out

A new 8.8 rear would cost the following:

$755 shipped for a stock rear end shipped to my door
$450 plus shipping for the detroit tru trac
$315 plus shipping for Moser Axels
$200 plus shipping for 4.10 gears
$180 shipped for the Axel Brace
$200 installation of the gears
$200-250 for instalation of the axels and other misc things.
------------------------------------------------------------
aprox 2300 for a braced 8.8 rear and that doesnt include welding the tubes to the pumpkin either


So i figured why not look into the 9" rear. its indestructable and ill never have to worry about it again, no matter how many passes i make at the track.

A complete Nodular Center Section, with a detroit Tru Track, 4.11 gears, fully assembled.


All of this is fully assembled and shipped to my door. Just needs to be bolted in and the oil added for $3500. Considering i already have a powerhosue driveshaft i sold for $600, this rear setup is gonig to cost $2900. Since there is no labor involved it stays at $2900




so the difference is aprox $2300-2500 for a replacement and braced 8.8 for added strength or $2900 for a complete indestructable 9" rear. IMO for a difference of $400-$600, the complete 9" is a stronger, better choice for reliability and a no worry setup.







sooooooooooooooo i went out and ordered the 9"+ rear from currie. Should have it in about 3-4 weeks as every order at the moment for the 05-07 mustang is built to order

Excellent choice! Should be nearly indestructable. Keep us updated with the install and review.

will do

Yeah, at this point what's another 4-600 bones. Piece of mind is worth that much :nice:

HUH!!!! I know you are supercharged and run at the track and all. But are these 8.8 rears that weak??? How in the world did you bend it????
Scott:dunno:

no idea how it bent. The 8.8 isnt that weak, but i have almsot 400-450 1/4 mile passes this spring/summer/fall and a lot of them with the supercharger, slipping the clutch at 5000rpm or higher with drag tires. i think its safe to say that a stock rear end without any bracing at all will not stand up to that for too long.

How much more does the 9" weigh?

i dont have the info in front of me at the moment, but it is a negligible difference, besides the fact that the added weight is in the rear of the car, where it is better off to help the weight transfer.

I am an old fart! Very familiar with the Ford 9 " rearend. Bet you can't bend it!!!!!!
Scott:grin: :grin:

ill do my best to try thats for sure haha but i kno i cant. not at my power levels, no way. I just want peace of mind, durability, and strength at this point. Which is why i chose a nodular center over aluminum

Just curious!!! Which way was it bent??? Was the pumpkim up high or was it low in the angle of bend? If up high... I would ask if you have been jacking the rearend via the pumpkin. If it is low I would I guess your awesome supercharger swat that did it. Were the rear tires toed in at the top or toed out??
Scott:dunno:

the funny thing is i didnt notice any tracking or drivability issues except for the acceleration at speeds under 40mph. it would sorta buck before i got to higher rpms. the noise i was hearing was from the carrier for the ring gear being totally bent and out of whack. the axel tubes were bent towards the rear of the car, suggesting that they bent from my launches on the track. the car was definatly jacked up by the pumpkin a few times. with it being lowered, its the only way to get the car on a lift that isnt a drive on type. the arms dont fit under the car with the lowering combined with the saleen side skirts.

I understand using the pumpkin to lift the rear of the car. Done it many times on many cars. Ford still says it is a NO-NO!!:nonono: :nonono: :nonono: The way your saying it is bent doesn't say much for the control arms now does it.
Scott

yea your right. well when i checked a few days ago my bushings are shot to hell in the lca's. BMR is not just sending me new bushings, but they are sending me new control arms. i have the old tubular ones. they are sending the upgraded design free of charge as a warranty replacement!

So :dunno:

It's only because of the lip on the diff cover. As long as you clear that, it's fine. Just covering thier butts is all thier doin, I'm sure plenty of people still jack it up there and crush the diff cover :-D

I agree Tony. I have done it many times. Just don't take your car in for warranty work if the pumpkin is bent upward. :grin:
Scott

,y car was on alift and someone bent my diff cover and oil started leaking out. great cover Ford!. i selaed it with silicone for a few days and then ordered the LPW one. with my new 9" rear i wont be able to use the diff cover nemore. anyone interested?

$$$$?

ok thread is back!!!

i dont even rememebr what it cost new? say 100 bucks for the diff cover? its basically brand new. only catch is i cant ship it till the 9" rear is in so it might be a few weeks
