can you tell if the driveshaft is from a non lsd or an lsd turbo gearbox.? theres a guy that has some driveshafts but not the gearbox.

excellent thread alan and one that needs addressing! moving to technical.
Here is the stuff ive managed to gather up to now,bear with me as the info on the net is a bit misguided and confusing,hopefully this thread will clear a few things up.
On the supported output shaft,these are the dimensions at the diff end..
And heres LSD (left) v non LSD (right) supported shafts,there is a difference between them at the spline but its very little and both shafts work in LSD and non LSD box's,although from what i gather some people machine 1/10th of an inch off each step on the non LSD shaft so that the splines sit 1/10th further into the diff,but its not needed.
Ive no pics as yet of short side stub axles for comparison between lsd and non but heres a useful piece of identifying info...
On the stub axle theres a lock ring near its end...lsd axles have 1/4 inch from lock ring to tip of shaft(diff side)
non-lsd axle have 1/8 inch.
I'll update as i find more,if anyone else can do the same preferrably with pics it would be great.
As you all know, I've been having major problems with my gearbox; specifically the limited slip diff unit, since installation. I've been unable to buy another lsd gearbox anywhere and the current plan was to get another LSD unit and install it... or bang Pauls non-lsd box in and take my to get reconditioned.
Well my dad began taking the driveshafts out and partially disassembling the gearbox today in preperation of me buying the new diff from Mark Edwards on IMOC. In addition to the non-lsd box from Paul, he also lent us a LSD input flange to try... here are some worrying results:

The three driveshafts are (from top to bottom, and the same order right to left) - my long side driveshaft, my short side driveshaft, Pauls shortside flange.
It's immediately apparent that the driveshafts that I have got with my limited slip gearbox are not the same as the ones Paul has pulled from his LSD 'box.

Note that the splines on Pauls LSD flange are much longer than those on mine... the entire end of the driveshaft is a good 5mm in length from the third metal shoulder to the end face. The circlip is in almost exactly the same place on both ends, but on mine there is only 2-3mm of splined shaft, whereas on the other flange there is quite obviously much more.
My dad also said that our short side driveshaft was extremely difficult to remove and the circlip on the end was broken when it came out (whether that was the cause or an effect is unknown).
The diff itself appears fine, from what we can see - there are no nasty bits of metal or shavings in the casing.

At this point I'm not entirely sure what to do.. I do have a feeling that we are getting somewhere though. It just didn't make sense that the gearbox should be fine and the diff working great at times but not at others.... but if the driveshafts are to fault, then it could well explain it; perhaps the splines not all the way in when you put lock on (and thus the inner wheel tries to pull itself out of the diff)
I'm not sure. But whatever the case, I don't think a new diff will solve it.
New driveshafts?

looks like i have just bought some turbo non lsd driveshafts from a guy on imoc - so i should be abble to help maybe, that will also mean that i will have a spare set of st185 drive shafts if anyone requires them?
Check out my 'Driveshaft Hell - Revisted' thread... It looks suspiciously like my 'lsd' driveshafts are not... going on Pauls description above.

by going from what paul said in the other thread, maybe it sounds like your short-side shaft is actually not an lsd one? someonce could compare for u
john just read this...you have def got non lsd shafts! now i suspect this is exactly why you have been having a problem.Which is bloody good news! all you have to do is get your mits on a LSD output flange for the left short side,the supported output shaft is practically the same for lsd and non (1/8th " difference in splines but shouldnt make a difference)
Do you mind if i move this post to al's one on shaft comparisons as you have some excellent pics in this thread.
threads merged to keep all the shaft pics in the same place.
John does this mean there is a rev1/SC LSD going spare now then ? nudge nudge wink wink !
sam you're a feckin vulture sittin on his garage roof just waiting...lol noit just means he needs an lsd output flange (throws a big stick at said vulture to scatter it)
