Diff bush replacement

Hi, I have a 2010 370GT skyline coupe, CKV36, with a ruptured differential bushing.  The local Nissan dealers tell me their answer is to replace the entire sub-frame, which includes considerable man hours, on top of the parts costs.

It all looks identical to the G35/G37 Infiniti, as described in the below YT vid,  where there is a suggestion that an aftermarket replacement bush can be inserted, rather than replacing the entire sub-frame.  What is the preferred way to deal with this?  Has anybody found a satisfactory alternative bush and successfully had it replaced?

Given that Whiteline have a poly bush kit (https://www.ebay.com.au/itm/Whiteline-Rear-Diff-Mount-Front-Bush-For-Nissan-Skyline-V35-V36-Stagea-M35/192741676619?fits=Model%3ASkyline&epid=1847214044&hash=item2ce04c964b:g:MS0AAOSwOI5dVAQV&frcectupt=true) available, I'd be sure that all the other usual suspects would too. Thus there should be no doubt that you can just flick the old Nissan elastogoosh bush and replace with something else.

Good to know.  I would like to hear some people's experiences with these tho.  The original had two chambers inside the rubber filled with silicone, which would have given a certain amount of movement.  I don't know the effect of going to something firmer or softer.

I have taken the temporary step of injecting some silicone based caulking, which is firm but I expect it will crumble away quite fast.  It seems to have got rid of a slight knock it usedta have anyway.

For the bushings I bought this:

For removal I bought this:

https://www.z1motorsports.com/transmission-driveline/z1-motorsports/z1-motorsports-rear-differential-bushing-removal-tool-370z-g37-p-11086.html

I didn't have time to remove it myself but when I had the clutch replaced, had it swapped at the same time.

My old sub frame bushing was well torn. The replacement made a difference. The tool to remove helped as well (I still have my old one, just lost one part of it).

I got it when Z1 Motorsports had a sale.

If it is the same as the V35, you can only buy an aftermarket bush for the rear mount, I tried to find rubber bushes, but  had no luck, so Poly bushes might be your only option for the V36 too.

I am not a fan of Poly for a daily either, it falls apart too quick and causes all kinds of squeaks and creaks when it gets a bit dirty

      Need AC Compressor for R32

      By GTSBoy · Posted

      R12 has not been not available for....decades now. Propane is not a great replacement. (I mean, it's a great replacement, but it is a bit too flammable). R134a being the only way to go forward with an R12 system. The design pressures etc, are close enough to R12's to work. The ability to move heat around is close enough to R12's to work.

      Out of curiosity, what's the reason for converting? I think @R3N3 might have the Frenchy's kit in the R33? I somehow think of you as the ambassador for realistic and clean street-driven setups nowadays

      V35 Overheat + Coolant Boil & Overflow + Engine not Starting

      By V35_Paul · Posted

      careful when running the car after a boil over. Ive heard you can lose enough coolant that it won't show the right temps because of too much air in the system (or something like that). Make sure the levels are good before trying again.  Maybe a mobile mechanic can come have a look with their scan tool ?

      OK, just for some extra clarity - there is more than one option at Frenchy's. 1. You can buy the whole kit - with or without the actual compressor. The whole kit includes mounts, hoses, condensor, etc. That's either ~$2200 or ~$2800. No surgery required with this option. 2. You can buy just the bracket (~$600), or the bracket with the compressor (~$1200). Either of this or the above option "without the compressor" is if you already have an Echo comp or you are able to source one locally. Whatever the case, in this option, you will need surgery done on your hoses to adapt to the new compressor. When I said "the Frenchy's kit", I meant the whole kit in option 1. It is obviously somewhat more $$ than a $1500 OEM compressor. But if I had to spend $1500 on an OEM compressor, I would certainly consider spending double that to renew and significantly update everything forward of the firewall. Another option is to rebuild your original compressor. My R34 comp is currently dead and I will be most likely doing that to it if the spare one in the shed is also leaky.
