I have a LSD out of an 04 SRT-4, I will just need the install kit and it will work in my 03 tranny right?

Thanks for any info.

If you have everything from the 04 tranny i.e. Bearing and such you will not need the install kit. How many miles did the trannny have? It might be a good idea to buy the install kit anyway to have the new bearings.

I think that the tranny has 3K on it.

You should not need the install kit, as you are not taking off the ring gear, unless you want fresh bearings and races. You will need a large assorment of the shims for adjusting it if it's a self install though.

Do shims come with the install kit?

The only thing that I am not sure about is the shims. If it was just a matter of opening up the tranny and swapping in the new diff, I would do it myself. If it has to be measured and shimmed, I guess I will take the tranny out, and take it to a tranny shop.

The Phantom Grip install on my neon was pretty easy, figure this is about the same.

Yes it needs to be measured and the appropriate shim installed. The great thing about the T-850 is no need to remove the tranny! But find an experienced shop as it's worth the money of not having the aggrevation.

No tranny removal, sweet. I should do a clutch soon though.

The shop should have the right shims then? Sorry, this is new from the old neons I am used too.

Thanks for the info.

The shop should know the specs also, or what?

Thanks

First; Yes it will work, a lot of us '03 owners have the Quaffe installed. Since Quaffe's weren't avaible in '03 it's obvious you have to use the '04.

Second; The install requires a special tool that measures turning torque on the shaft, the turning torque is changed by changing shims. As far as I know the shims are only available from Chrysler. My Dealer had to order the shims from a Mopar parts warehouse. The specs are in the SRT4 manual.

I know that people have quaifes in 03's but almost all of them were new not out of 04's used. I read somewhere the there were 2 different part numbers for the LSD, one for 03's to use for the upgrade, and one for replaceing 04's. That is what the post was origionally trying to clear up.

So, the shims are not part if the install kit?

I am getting a whole tranny that had the flex plate shot through the front of it.

The 2 part numbers are because one is a replacement part (for '4's and 05's) and the other is the part number for the 03's (includes the ring gear).

I bought the diff and the "install kit". The install kit does not come with the shims.
The local Dodge dealer I bought the diff from told me I had to also buy the install kit AND they wanted $900 for just the installation of the diff, saying the entire trans had to be removed.

I told them F all that and argued that the trans doesn't need to be removed from the car.

Anyway....

ADJUSTMENTS
ADJUSTMENT - DIFFERENTIAL TURNING
TORQUE
NOTE: Differential turning torque should only be
measured with the geartrain out of the transaxle. If
measurement is taken with transaxle assembled, an
inaccurate measurement will result.
NOTE: All differential cover-to-case bolts and bearing
plate-to-case bolts must be installed and
torqued to obtain accurate measurement.
(1) If transaxle is assembled, remove geartrain
and leave differential in place. (Refer to 21 - TRANSMISSION/
TRANSAXLE/MANUAL - DISASSEMBLY)
(2) Install differential cover and torque differential
cover-to-case bolts to 54 N·m (40 ft. lbs.).
(3) Install extension housing and torque extension
housing-to-case bolts to 28 N·m (250 in. lbs.).
(4) Place transaxle on work bench so axle centerline
is parallel to the ground.
(5) Install turning torque tool C-4995 to differential
at side opposite extension housing.
(6) Using in. lb./N·m dial indicator, rotate differential
case multiple times and record measurement
(Fig. 100). Differential turning torque should be
within 2.3-3.4 N·m (20-30 in. lbs.). Refer to shim
chart for proper shim selection. If turning torque
measured is less than 2.3 N·m (20 in. lbs.), install a
thicker shim. If turning torque measured is greater
than 3.4 N·m (30 in. lbs.), install a thinner shim.

So, that means that I do have to take the tranny out and disassenble it totally to adjust it correctly. That sucks.

Sound like everyone that has installed the quaife with the tranny in the car has done it wrong?

Honda Hunter; Sure sounds like they were wrong to do the install that way. I know that I couldn't afford to replace a Quaffe because of incorrect installation so I had the Dealer's service department do it. I got lucky, the shop foreman (Viper Specialist) did the install by the book, even showed me the special tool and how the turning torque was measured. The peace of mind was worth paying the dealer $450 + fluids.

my quaife was installed without removing the tranny......I have put almost 10,000 miles on it since it was installed. No problems here! Works perfect! :thumbsup:

If you go by the book, the torque on the diff should only be measured with the geartrain removed from the tranny. You obviously don't want to take the geartrain out, so here is what you do. Measure the torque on the stock diff while it is still installed, then shim the quaife so that you have the same amount once its installed. Most of the time you can use the original shim, so I would start with that. Good luck its a tough install.

I will probably do it this winter since I don't drive it year round. I'll probably drop the tranny and do it myself. The dealer I used to work at has the tool and will let me borrow it. I need a clutch anyway, I'll do that at the same time.

anyone know a good shop for a Quaife in Texas. I live near a military base and there are nothing but shady people around here. I'm going to pull the tranny and was going to have it shipped to CA for the install but I would like to get it done somewhere closer to decrease my turnaround if possible.

Ryan, do you still have your 03 diff by chance?

What is actually in the install kit? Does the 03 ring gear have to go onto the 04 diff?
