There is no rebuild. If viscous diff, then the viscous cartridge is gone. It never was any good, but now it is just completely useless. If helical diff, then no rebuild available there either, but also very unlikely that it would stop working, therefore probably viscous.

Do not listen to anyone who tells you about "shimming" the diff as they do not understand what they are telling you to do. I don't care if it "works" because all it is doing is creating a wear surface where no wear surface was intended to be.

Not entirely true, You can rebuild it but is a lot of work for minimal gain. If your curious have a look at post 154 in this thread http://www.skylinesaustralia.com/forums/topic/164288-diydiff-shimming-for-r33-gtst/page-8?hl=%20shim

But as above don't shim it, it's dumb and doesn't actually make the LSD part of the diff better. it just puts more pressure on the spider gears in he middle causing it to lock.

If its a street car, just grab yourself an r34 Helical. if skids get a mechanical.

Very impressive job, I wonder how the LSD functioned long term.

That air pocket he spoke of is interesting. My understanding is that the air pocket in viscous couplings is necessary and must be a carefully measured volume, making the process of building them beyond a DIYer.

None the less, if it does the job, it does the job.

      Cleaning my wheels 😍

      By PranK · Posted

      A little follow up here on the ceramic coating.  We've had storms galore here and I've done a few ks, enough to gross them up  Consensus is that they didn't get as dirty as usual, the coating definitely repelled a little of the dirt and I think they kinda snowball. They get a little dirty and then they get dirty faster which makes sense. Cleaning them regularly would allow them to protect better.  Cleaning was a breeze. I tried first to just hose them off which, unsurprisingly, did nothing. But, making the wheels wet and then just wiping them over with a used but clean microfibre cloth was all that was required. I didn't need any cleaner at all, just water and a cloth. The wheels look amazing again.

      Gave her a nice wash today and took extra time to clean off the tree sap and tar and crap. We have a usable garage now so she'll stay cleaner longer. Took a few snaps in some nice light afterwards.

      Duncan's V37.......race car?

      OK, solid mount Z1 diff brace is in, pretty straightforward, it picks up 3 diff hat bolts and ties them to 2 support bolts on the subframe. Pretty sure someone else on here said they had reduced axle tramp with this but mine was already pretty good for smooth wheelspin, and still is....will see you this goes over time and whether I end up with a broken rear diff hat

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      Ah yes, but the part in my hand was actually painted and fitted by me! I knew any front lip was likely to be sacrificial but I've had to fix it twice already... by the time I buy a fibreglass fixing kit, sort out sandpaper blocks, buy some fibreglass filler, body bog, spend the time and effort for a 'Greg' result... a new one being $290 seems like it's the better way to go and spray that with bedliner/raptor coat and we're all pretty again.. Would have preferred it last more than a month though. Them's the breaks I suppose.

      I find it funny that the USA is finding out all this really really weird stuff, and people from the USA are coming here treating it like gospel, yet, all the info on solving those issues is here on these forums for the last 15 odd years... Also, I know how much heat it takes to ignite the hood lining of an R33 skyline. I worked it out myself... It also took a LOT of time, and heat for it to do it... Big single, and I needed to drive the car, so retarded the timing off to "protect it". Yeah, that was a bad move for cruising on a freeway with only 15 degrees of timing on it. That was a lesson I learned around 2009. So that's over 15 odd years ago. Aligning water and oil, that's identical for any turbo engine, it's not Japanese specific. If a shop doesn't know how to make sure the core is rotated the right way, then they shouldn't be touching any turbo engine. That's not a matter of "We haven't had Skylines for that long here"...
