i have a 94 gt with stock 3.23s

 

i have a question about setting up my rear end on my 92 mustang. my friend recently wrecked his rear end and had to buy a new one. he had 3.55 in his car and gave them to me for free. i know a little about the specs and i can easily access a press, but my question is about the crush washer. the first attempt i made failed miserably, i guess it was because the crush washer wasn't crushed completely. i had play front to back with the pinion. i know the pre load for used bearings are around 15 ft lbs and new bearings 25-30 ft lb. does this mean when i apply the 15 ft lbs it will crush the crush washer completely? thanks

 

thanks anyways guys i figured it out. hit with a 1/2 impact till there is no play and you get a slight drag when turning the yoke. check the blacklash.(mine was .10). and mark the gears.the pattern looks good, gonna put back together on weds. hope it works

 

Sorry to cut in, but I have a question about gears. This may sound stuipd but, I have never own a car. If I were to buy Ring gear and pinion set on line would a shop install them for me? I found an set on newtakeoff.com and was not sure if this would work to buy my own parts.

 

depends on the shop. i would ask them first before i bought anything. i know i looked into that before i decided to do it myself and it basically didn't save me money at all. remember they're in that business to make money so they want to use their own parts.

 

The door tag on my AOD 92 LX 5.0 is "M = 2.73". The "Fox-body Mustang Recognition Guide" states that all 5.0 Liter1992 AOD carscame with 3.27gears only because it was the only ratio available to 5.0 AOD's? Is there anyother simple way of confirmingwhat gearswere really installed in my cars rear from factory?

 

I run 325s in my ranchero and love them, perfect for street and highway with a non world T5, 1st gear is real low as you know and the 325s give me a lot of top end 160+ last weekend next to a Viper, of course the motor Ibuilt helps a lot, a little ol 302 block / 289 hipo internalsbalanced& shaved and only 410 HP eats chevy's like a garbage disposal eats celery and sucks the head lights out of those ever present rice rocket's.

 

a friend of mine just switched from 3.73 to 4.10. His quarter mile times pretty much stayed the same yet oddly enough his mile an hour went up.

 

OK, I am building a 91 notch strictly for the strip. I am going to go with a 3.73. The question that I have is: Did Ford ever make a 7.5" limited slip with a 3.73 and rear disc brakes? The reason I ask is that I have that very axle and when I throw a tape across the ring gear it measures closer to 8" than 8.8" which leads me to believe it may be a 7.5"

It is an axle for a fox body because it has the pucks for the upper control arms. I just cant imagine Ford would make that axle in a 7.5. As far as I recall, the only cars that had the disc brake rears prior to 94 were the cobra's, the lincolns and some of the t'birds.

If you KNOW the answer, please reply. I really need to have an 8.8 as opposed to the 7.5

 

7.5" = 4 cylinder car. You can also check the VIN. But, an 8.8" rear does measure closer to 9" than 8".
