Question for owners of welded diff - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Kouki · 05-04-2005, 07:34 PM

I was going to weld my diff this weekend(can't afford nismo 2-way

), and I was talking to my dad, and he kept telling me not to do it cuz I'll break axles if I drive it on the street. Well I searched and couldn't find anything about people breaking axles from having a welded diff.

So my question to all owners of welded diffs, have you ever broke axles, or tore up anything else in the drive-train that was caused by the diff being welded? Help me decide what to do. Should I weld it? Should I leave it open for now? Should I just wait till I can afford a 2-way lsd?

infinitexsound · 05-04-2005, 07:51 PM

your gonna break axels with a 2 way also.......................................

Flybert · 05-04-2005, 08:32 PM

Your tires will break traction before you break your axles.

JDMark · 05-04-2005, 11:03 PM

tons of people up here running welded diffs, from what i hear its very predictable and isnt as bad as people think for daily driving. dont worry about breaking the axles just weld it and go driving. i havent heard of anyone yet thats broken an axle from it.

racer98 · 05-04-2005, 11:39 PM

also from what others have said it will tear up the clutch! and its not fun when your on a slick or wet road.

sw20>>s14 · 05-05-2005, 12:00 AM

not good in the wet...if its welded properly, it wont break

007jpang · 05-05-2005, 12:08 AM

there's hella fear and bullshit on the internet of people saying
that the 240 will whip out if it rains with a weld diff...and
that axles will break...
it will lock up on a turn...

well i have had my weld diff for about 2-3 months drove in the rain plenty of time fast too... and this weld diff does not whip out if i don't want it to...

the diff is very predictable and yes axles will break ( just don't use super sticky tires in the back and burn out doing donuts for 1100000000 times)... but as mentioned above they will also break if you have a 2 way... either way if your drifting shit will break.

and since it is a weld diff that shit is always locked up... basically a weld diff just make both wheels spin at the same time all the time. So it like a 2 way that's always engaged]]

And if anyone wants a bullet proof welded diff in the bay area just
call up LUKE 1-408-515-9598
New price

$120 for Welded diff (bead blasted, cleaned,new gasket, like new) I think you need to exchange with you open diff not sure though... just ask him
or

$75 weld it up front, but you need to drain the oil your self

ghostuss · 05-05-2005, 12:28 AM

since when you had a welded diff John? I remember we went to stockton event and you had an open diff.

Oh btw, yea welded diff will break axle. More than a 2 way cause it's always engaged = constantly putting stress on the axles. But fuck the axles are cheap. With that 600-700 dollar difference you can buy as much axles as ur car will last.

i dont think 2 ways lock up on neutral and they dont spin exactly, all the time...

edit: nv, i somehow read your post wrong...havnt had much sleep lately...

He said it's LIKE a 2 way that is always engaged. He didn't say a 2 way diff is always engaged.

infinitexsound · 05-05-2005, 01:28 AM

If u WELD it, things will break....save money get a vlsd.. like whoa im selling one i might add... = ) but will not ship unless u wanna pay a 80 dollar shipping fee..

007jpang · 05-05-2005, 01:30 AM

hey infinitexsound if you did not get a vlsd yet , don't get it cause if the fluid gets too hot it will not grab and that will make it act as an open diff.

nigel1 · 05-05-2005, 01:35 AM

I think I need to weld my diff... but what I am worried about is when I drive in the mountains. will it hinder my performance on mountain roads??? because thats the only thing holding me back. I wana be able to rip around corners with grip too without having to worry about crashing because the ass end came out when I didn't expect it or want it to...

r thizzel · 05-05-2005, 01:44 AM

wat welder did everyone use on their diff? I have a "stick" welder..strong enough?

AeBaSupLook · 05-05-2005, 01:45 AM

I remember talking to Luke at the track and the first thing he told me was he was running a welded diff. I was surprise and thought he was joking... But then I saw him pull his car off the trailer and see the wheels both wheel just fighting each other. I didn't get to talk to him at the test day event because we were all busy tearing shit up... Yea, talk to Luke about welded diff, I'm sure he will educate you all about it.

A arc welder is good and offer a good and deep penetration. However its hard to get inbetween the spider gears and get a good weld. Try using a good mig welder.

infinitexsound · 05-05-2005, 02:24 AM

stick, runs to hot but wouldnt doubt it for getting the job done... but warpage is a criteria for using it....200amp is deep penetration.. 160 would be least i say...migs are nice ill buy a 210 when im done with school and its able to weld alluminum..

s13gonwild · 05-05-2005, 03:55 AM

Things break when you drift period...if your going to bitch about it dont drift at all. And make sure you weld it good. Ived had mine for couple of weeks...love it for the price i paid FREE hahaa...also maybe you should get a spare diff to weld....(i did that) so when rain/winter weather comes by, you can swap out the welded and throw the good ol open diff in.

Good luck

m0rex · 05-05-2005, 01:03 PM

It gets really slick when its cold around here. If you weld your differential tell me how it goes i might do the same as soon as i get done finishing my quarter panel.

infinitexsound · 05-05-2005, 02:49 PM

yeap if u build a 240 it will break... nope im not purchasings a vlsd.. cause i already have one...i want a welded diff because i want something solid for the events this summer... cant afford da clutch cause me no have no big faces....and i just wanna get rid of it because i have 2 spare diffs... and would like the extra income... yah smell me? pop my collar !

raging panda · 05-05-2005, 03:35 PM

i have a welded, if you have bald tires, and you break hard into a turn, it will lose traction when you dont want it to, i know that for sure. otherwise, it just makes squeaking noises around tight corners and makes you want to understeer into every curb in front of you, but when you slide its nice. If you like grip, i wouldnt do it though. For drift, its great. I havent heard of anyone first hand breaking any axles ever, but there might be one or two people on the net with 240s that have snapped them. I also have spare axles and a spare open just in case one of the two break.

verdict: thumbs up here

When you say" If you like Grip, than dont get one" What do you mean? Could you ellaborate on this subject?

How would a mig welder make access to the gears any easier than a stick welder. A stick welder would be easier, but since its no problem to get a mig's gas cup in there, what you said makes no sense.

Drunk Bastard · 07-02-2005, 10:33 PM

ok, i've been running a welded diff DAILY for almost a year now. nothing has broke. it will ONLY slip out in the rain if you have bald tires and come in hot. otherwise, it drives fine once you get used to it. oh, and if you ever switch back to open diff...hahaha....you're gonna realize even MORE how good welded diff or 2way really is....all in all open diff SUCKS, just weld it and get it over with.

Being as both tires are 'engaged' 100% of the time, it'll b alot easier to make the tires break loose. Grip racing isn't so safe with a welded diff, being as most turns are meant to have different turning revolutions for better cornering. So with a welded diff, while cornering, one tire will grip (inside) and the other tire will not have much traction and might squeak.

Drunk Bastard · 07-03-2005, 12:47 PM

^^ i think y ou have the tires mixed up. the inside tire will "squeek" and the outside will grip, considering that they are both moving at the same speed and the inside tire has to travel less distance with the same amount of rotations... its like making a u-turn. inside tire will always skuff

raging panda · 07-03-2005, 02:46 PM

i meant grip racing, no good, understeer everywhere, it will probably hurt more than help. I didnt mean anything about safety, i dont see why it wouldnt be as safe but it would suck for track racing. For drifting, its a 2 way while you are sliding as far as im concerned.

HyperTek · 07-03-2005, 03:26 PM

dont worry, the axles wont break, its not a honda =D

SochBAT · 07-03-2005, 09:22 PM

Bastard, you are right. Its the inside thats the squeaker. And Panda, understeer??? i'd think with the welded diff, it'd be oversteer, for loss of traction from one tire while the other is still gripping. I really don't see how you'd really increase chances of understeering with a welded diff.

On another note, anyone thinks there doesn't need to be gear fluid inside? Me n the guys argue about it alot.
