WELDED DIFF??

Does anyone know if you can weld the diff on a mustang? I know every other 240sx has one. Just seeing since it has a trac-loc if it was possible.

Sure you can. All u gotta do is weld the spider gears to the ring gear- spin it 180, then weld that side- not that I'd know ... ha ha ha.
Sweet. Well thats what i figured but i was reading up on it and people were sayin diff things. I know its not the safest thing to do but i think that it would be ok for awhile.
you can also pick up a mini-spool for pretty cheap.
Mines been welded for........thinking......4 years? Not safe my ass- just wouldnt recommend it for a daily driver- those tight turns are bound to break something. Its also pretty hard on all bushings tieing into the rear end- but you can always do what I did- replace that with all sphearical bearings.-
The new car will be full-spool.
well the for right now is my daily driver. i was just looking and you can buy the mini spools for cheap. if i was to go that route would there still be a chance of breaking something? Do you haved to reset the whole rearend if you do a mini spool?
Geoff would know better than I would on that- it should be just like changing a pinion gear labor wise. If you're running stock rear end control arms, bushings, etc, they'll wear pretty soon- also, good luck driving that thing in the rain- and forget about ever pushing the car and trying to turn. A car with a welded or spooled diff turns from a 3,000 lbs car to a 5,000 lbs car as soon as you turn the front wheels just slightly. But, it kinda doubles as a park brake which is cool.
When the rear end is fully locked, you're trying to turn without slipping the tires (like drifting), it just binds up in the rear end- hence wearing hard on the only "giving" part, the bushings. For example, my buddy Calvin has a KAS14 with a rediculously aggressive 2 way LSD. Its so aggressive, normal street driving wore out all the rear sub frame bushings in a matter of about 6 months.
I've actually heard that lots of road race mustangs and even JRs mustang run a torsien- Geoff can you confirm?
This is the reason that I went with the air locker. Open on the street, spool at the track.
I have never met someone who was happy with their street car after putting in a spool.
You could try using the F-150 S spring and an extra clutch in you stock differential for a cheap track/street setup.
This week I've had my Diff welded :) Despite all the new sounds that appear and disappear after some minutes I TOTALY LOVE IT!! It has made such a big difference since the stock Diff. I realy sugest everyone to weld it if you don't want to spend lots of money on 2way's or air lock(i dont know how much does that cost)
The Air Locker setup was about $1200 by the time it was all together and in the car.
WOW now that's hell of money to spend on a diff! Mine costed me ~50$ :D
i would take an air locker any day over sacraficing my diff forever by welding it..
Fortunately stock mustang diffs can be had cheap. If I was building a pure track car I would have gone with a spool, but since I put about 15k street miles on the car each year, I needed to be able to open it up for the daily commute.
What about 2way LSD's are there some? Like for Nissans?
Yeah if you can find one let me know-
My Welded Diff broke down and the sad part is that It broke down in my first official event :((( The problem was the poor welding machine (not an electode one) and that it was welded while still in the car, was not taken out. So in the begining of the event before f'ckin up the first set of tires I noticed that the accelerator sensitivity was not that good so I went to check the diff and I noticed that It's open :( I was told that It's almost imposible to weld the same diff, so I'm shipping a new one or some from the scrapyard. Whitch one would you buy? How much does it weight?
that sucks ..............any one know whats the best kind of welder to use when welding a diff .............. because i plan on doing it when i get my project car ......im going to be on a buget
