was out on drift day and car was shit

 

it actted like open diff and having read many posts everyone says it is lsd however they wear and either need ri shimming or change oil

 

some said it is open in first and lsd kicks in, in second gear which again mine was spinning on one side throughout

 

so what would you do?

 

don’t want to weld it as it is a daily car

 

secondly hicas has not being removed so it still has hicas but fuse pulled

 

could hicas even though off be causing it to work as open diff?

You don't say what kind of car you have. Never heard of an LSD which was "open in 1st" nor that a change of oil will fix it.

What would I do? What I did  for my car was to buy a rear end from an R32 GTR which gave me a mechanical LSD, GTR axles and brakes and in your case would do away with the HiCas.

Or you could just get a known good or new LSD and a proper HiCas delete kit.

Stock diff is a viscous LSD, changing the gear oil inside the diff housing won't so anything.

Your options are (starting from cheapest

1. Shim up it's mum up

2. Hit the centre with a welder, weld up it's mum 

3. Install a helical centre from a R34 GT-t Series 2 (rare as shit, but maybe you'll find one in the UK out of a stolen burnt out wreck because some lads took it for  spin)

4. Buy a proper LSD.

i quite like option 1 .

 

my car is r34 gtt 98.

 

don't want to buy the entire rear end from gtr as that will be expensive and too much work.

have seen following as well which i suppose involves removing my internal and installing this

As if you only have to buy from the UK.  You could get it something direct from Japan, you could probably call Quaife (if you wanted a helical) and get them to make you one right there in the UK.  You could go and watch them make it.

I wouldn't weld a diff....too crudo 1990s stylo for me. Horrible to live with too. As I said, do it properly, or don't do it at all.

    • I'll just reiterate that it's best to do all the wiring diagnostics, before even thinking about buying replacement solenoids ~ that is, be absolutely sure the solenoid is bad.....ie; bad connector(s), rodents chewed through a wire, etc etc. If you don't so this, you can fork out all the money for solenoids, only to find something else is wrong (this'll make you cry if you pull the valvebody only to find a broken wire is at fault... ...some more glue on the solenoid packs -- this is the RE5R01A shift solenoid assembly.... ...these are all shift solenoids ~ ostensibly they're the same as the shift solenoids from the 4-speed auto.... ...this is the RE4R01A solenoid set... ...with these, you have 3 shift solenoids attached to the plate, and the separate solenoid is the EPC solenoid (line pressure control) -- with both designs, the TC lockup clutch solenoid (also PWM so they could slide the clutch shut), is located on the lower valvebody half.... ...(story time)...back in the 90's, it was a common fault that the EPC solenoid (or TC-lock solenoid) would fail, but Nissan only sold them as part of the assembly (think ~$350 at the time) ~ thing was, Isuzu also used these boxes in light commercials, and you could buy the PWM solenoid as a separate part, so it was possible to buy/use that solenoid (around $65), and make it fit (remove the circlip, fit to old plate and deal with wiring)...making it a more cost effective repair. I've not seen the RE5R01A shift solenoid assembly, but with the 4-speed RE4R01A it was possible to hack/fit a single shift solenoid onto an other working set, using a donor solenoid from another set with failed EPC....(by rights the whole set should be replaced), but it ends up being a question of how much life is left in the box itself ; sometimes it's a viable repair to fix one solenoid, just to get another 100k of road miles out of it before it needs first overhaul...other times the box is that old/worn, you're as well doing first overhaul and replacing the solenoids and starting fresh... What Nissan did here with the 5-speed, was relocate the EPC solenoid to the lower valvebody (next to the TC lockup solenoid), and stuck the direct-drive clutch solenoid (for the extra gear) where the EPC solenoid used to be on the 4-speed....I can only imagine they did this for serviceability ; the PWM solenoids are most likely to fail, and it's a doddle to drop the pan and change these out (as opposed to dropping the valvebody itself to get at a top mounted EPC)... ...also keep in mind, that some BMW 3/5 series & Mazda (and maybe some Ford/Mazda rebadges, not sure), also used the RE5R01A box under a different name/part number...not saying parts availability is any better, but sometimes it helps to know this when it comes to NOS floating about in the EU....

    • FWIW, air jacks are actually pretty light and simple to add, they are just 4 hydraulic cylinders (often at the main cage A and C pillar points) and an externally accessible airline  - they make quick work a breeze

    • That is porn and I wish I could do it easily on my streeter.
    • Yes there is a front and back insertion point on each side, each point is tubed with supports into the car and tied to the cage/ floor mount point
