Need a DIY for diff swap

[smocan]

thanks for that thread, but its very general on the taking out, and puting back in part, and thats what i need. I'm just taking out the entire diff and puting the stock one back in. i dont need anything on the inner parts of the diff...

i gotta ask, why are you pulling the welded diff and re-installing the stock one?

I posted this on another thread in here, applies the same:

Unbolt the crossmember on the driveshaft, unbolt the driveshaft from the differential. It makes life easier to take off the swaybar if you want to because it gets in the way of lowering the differential a bit. Once that is all done, unbolt the axles and push them up and out of the way. Then put a small floorjack or jackstand under the differential and proceed to unbolt the four bolts in back holding the differential to the frame. Everything should be free now, lower the jackstand or whatever you used and you're done.

Reverse that for putting it back in.

**** if i were near you i would do that with the quickness.and that **** is heavy if you havent held a diff before, so if you try it without a jack under the diff, be prepared for where it will land.

Usually, it wont pass inspection with the welded diff in, normally because its considered unsafe for road use. I need an inspection now so it needs to come out. Plus, its ripping my tires up like no other. But let me tell you, if you own a 240, you have to drive a welded atleast once, its fun to say the least, but for me, i need my car more on the practical side for now... i will be selling the welded soon if anyone is interested for pick up, definitely NO SHIPPING.... i dont think many people realize how freaking heavy these things are. But i'm taking it out tomorrow.... so who ever wants it, let me know

Hi 2 all….

I am looking to weld the rear diff on my newly purchased late 1993 s13 180sx (240sx) with SR20DET. (Non ABS)

There seems to be a lot if confusion about the S13 rear diffs, some being non VLSD and some having factory fitted VLSD.

I am pretty sure that my car has VLSD purely due to the way it drives and feels, plus I have lifted the rear wheels and YES they do turn together at the same time…

I have had a look underneath the car, and noticed that the output shafts had 5 bolts and not 6 which confused me even more as I was expecting it to have 6 bolts…..

I need to know….

1. Is the current diff in my car a factory diff…..??

2. If not then, which diff is it and which car is it from….??

3. Can I weld a VLSD diff and where do I make the welds….??

4. If i don’t weld my current VLSD, Can I use the internals from a S13 OPEN DIFF to weld and place them in the currant diff casing on my car, saving myself time from changing the whole diff casing as well as the shafts?

What ever info you have please keep me posted as I will be starting work on the car soon.

Thank you…………

All the time you have spent posting, you could have searched and found your answer. Read up on welded diffs before you decide you want one. It is very dangerous on the street, plus since it is always locked, your tires will chirp everytime you make a turn.If you already have an lsd why do you want to weld? If you want a true locker then buy one, there are many choices

Undo driveshaft bolts... undo axle bolts... jack under diff... unbolt the 4 rear.... bolts.... and bam there she is.no precautions except heavy as h3ll
