Half Shafts! *snap*

Recommended Posts

ok....

 

broke my first half shaft in the 1via yesterday :( not sure if its a common place but it was a super clean snap just before the spline near the outer end.. will put pics up tonight

 

now ive been running my car witha S14 rear subframe etc.. and i have the 6 bolt style half shafts. are these S14 ones? as i got spare half shafts but they are from a S13.

 

my old 180 has the 5 bolt half shafts so im guessing the 5 bolt ones are s13 correct??

 

just wanted to ask what half shafts are what?? and whats the strongest 6 bolt half shaft you can get?? if you can??

 

any input would be great

 

Cheers

Jake

 

oh and i wasnt even drifting when i broke the half shaft... was putting the car in the shed <_>

im surprised it took this long for you to snap a half shaft as I was snapping them pretty quickly with a relatively similar setup (rb26+s14)

 

the only half shafts that are thicker are gtr ones

 

s14 are the same size as r33

yeah i was shocked when it did :lol: and i think the biggest half shaft killa is people not releasing the handbrake when they go to put the power back on when drifting... thats what i think anyway!!

 

so S13, S14, R33 all the same?? just diferent styles? 5 bolt and 6 bolt etc..

S13 have both 5 and 6 bolt shafts... unsure if s14/15 have both kinds also.

the 6 bolt shafts are weaker if they are the 6 bolts in 3 places

if they are the 6 bolts spread out evenly then they are gtr

the 5 bolt ones are skyline and late model silvia

 

just get gtr ones they are thick as f**k and strong as hell

but you will need to change hubs and diff

 

otherwise go 5 stud as they are stonger then the factory s13 6 bolt

and the half shafts and driveshafts are the same size

Everyone knows I'm an expert at this problem after breaking two at the same time on national TV.

 

I broke more after the show too.

 

You have three solutions.

 

1. Change to 5-bolt shafts. They are only marginally stronger but still slightly stronger.

 

2. Buy billet driveshafts or custom driveshafts from the drive shaft shop. I jsut got some from the US but they cost around $1200AUD plus delivery. I havn't used them yet but from looking at them and based on being rated for 850hp they should be fine. They aren't cheap but at least you dont have to buy new diff, centre etc to suit GTR. The ones I have use Porsche competition CVs with thicker shaft ( GTR size) and seem to be pretty awesome.

 

3. GTR rear end. Need GTR diff, new GTR diff centre, GTR driveshafts. Bolts in but must change spline in the knuckle to suit. Virtually un-breakable but they are second hand so depends what they've been through. Pain in the arse as have to chagne a lot.

 

 

I went for driveshaft shop as I already have 4.3 diff with Nismo centre and Trust cover extension so easier jsut to get replacement shafts.

 

 

I'll post up pics soon.

hmmm seems like a fair enough idea with the billet shafts but seeing as though its taking me almost 1 year to break a half shaft with 320rwkw i think i can deal with that fro now haha...

 

and yeah ill chuck in 2 more half shafts this week before winton.. ive got 5 bolt half shafts sitting here also but dont have the things that go into the diff lol..

 

should be right :) im still shocked at how clean the snap is... it look like its suppose to be like it :S

a very wak way thats for sure... dropped the clutch with the hdanbrake still on. stalled!!! started it up and took off with 1 wheel spinnin... :S so i done a test skid/burnout and yeah... it was 1 wheelin haha...

 

must have been on the way out coz i couldnt see how that was too much force??? but the snap in the half shaft was so clean... it doesnt look right thats for sure :(

 

lucky it happened in my shed instead of winton this weekend :)

I broke one set on a launch

broke another one pulling second

broke another one clutch kicking 2nd

 

I have a very aggressive clutch though.

 

5-bolt are stronger but only marginally. CTS car used 5-bolt for a whole season but changed them every event to be on the safe side. then they went GTR rear end and never touched them.

 

5-bolt is only a very small upgrade but if you have 320rwkW there is a good chance youll break them too.

 

it really comes down to how you drive and how much time and money you want to spend on changing them

its taking me almost 1 year to break a half shaft with 320rwkw i think i can deal with that fro now haha...

its more to do with savage clutches and jarring than KWage, thanx fot the mention too btw :P

 

When I got JV's old S14 [but fitted with 5 bolt] I broke the only half shafts I've ever broken at Parklands

running with the super savage HKS clutch it had in it, it made a loud noise

so I did exactly what you did [and any normal drifter would do]

and skid tested it :lol:

 

and broke the other side as well... :o

After fitting the softer Nismo Coppermix clutch I've not broken one since

 

I've often wondered what makes the 5 bolt stronger than 6 as the shaft size seems the same and its not the bolt holes it breaks through.

I've also wondered why in early S13's [most CA18's] 6 bolt were fitted, then they went to 5 bolt, then towards and including S14/15

they went back to 6 bolt......

 

Maybe just purely cost cutting? :huh: nfi

your right fro

 

my clutch is one of those NPC twin un-sprung 5-puck clutches

 

very savage.

 

Im gonna try a Nismo clutch in my 14 next ( have single in my 13 and its 110% awesome)

 

I hope the Coppermix twin plate can handle the power though. 400rwkW on E85 is adequate for time attack

yeah im only using a extreme heavy duty thingo.. single plate that slips very easy... cant do stand stills as the clucth will just slip etc... thats why i started doing the whole 360 burnout thingo haha... no brake skidz FTW

 

anyway im sure as all hell i would have broken heaps if i had a strong clutch.. kinda happy i dont :)

 

new half shafts are going in tonight.. just some random 180 6 bolt ones.. if anyone in adelaide has anymore lying around let me know and ill buy them ;)

 

Cheers for the words everyone :D

I snapped both sides at the same time in my old onevia, brand new tyres, new twin plate, 300kw. Went bang!

 

I've got a set of GTR rear half shafts and GTR rear hubs here to go in my new car but I've got more coming if you want to upgrade Jake! Just need the output shafts from a GTR diff I'm pretty sure.

wow, you realise you don't need to pull the whole hub assembly apart to get the shaft out right?

Also snapped the left 5 bolt halfshaft whilst push starting. Went around the track twice with a constant thump in the rear, couldn't figure out what it was until i noticed i couldn't get sideways and smoke was only coming out on the right side...
