yeah. lock washers.

i ended up solid mounting mine. it just so happend there a 3inch bush.

a trip down to edcon steel for some 3 inch round plates.

it was abit tricky getting the whole lot centalised. (car at home and subfame at work.

i ended up putting nismo diff bushes in to. old ones werent there lol.

it moved the subframe up around 1 inch. wich is a nice handy roll center adjustment hehe.

Thats what i've found with the rest of my suspension bushes. I don't have a press and couldn't budge any of the stock bushes with a bench vice and dies, but pressing new ones in with the vice was a piece of cake.

Except the front upper control arm bushes. Hammer and screwdriver got them out easily enough :happy:

yeah cutting them out aint a problem. i was worried about putting them in. i dont wanna buy a press for 1 job.

i suppose ill have to try to hammer them in, i got a mini sledge i could use. maybe if i grease them up theyll slip in easier.

steve

dont hammer them in, use 2 plates with holes in the centre, i piece of tube, and 1 long threaded rod with 2 bolts.

U put 1 plate on 1 side of the frame, put the bush where u want it pressed in, then fit the tube on top of the bush, then the plate. (this stops u pushing the centre out of the bush itself) Put the rod through the centre of it all and screw the nuts on either end..

Basically u do the nuts up to press it on...

freeze the bush before hand to make it easier and use a long wrench to tighten the nuts...

can't a portapowa be used for this?

Yes, but with special tools that you would have to make first.

Of course I left one possibility off;

#4, customer loyalty, where he does it for a good price because you are a regular customer

Until a 100 guys from the SAU forum turn up asking for the same price :huh::(:no:

Then he hates you and you won't get a good price ever again :P:):)

:D cheers :D

sweet idea!! those things i do have i the shed.

thanks for that.

For sure, but then you can take the press to the subframe instead of the other way around, it might save dropping the whole subframe. Of course this would only work if you can get sufficient clearance, never done it so not sure if this is possible.

My Noltec subframe bushes are in. They can be had from Unique Autosports for ~$190.

Here's how I went about it.

In short the process of removal:

Wheels

Callipers and sat them on a box so they don't hang

Sway Bar (makes life easier)

Tail shaft

Exhaust cat back

Removed hicas lines from rear steer rack and tucked them out of the way

Disconnect Hand brake lines

The hicas wiring ran under the hand brake line, unplugged and replugged so it ran over the top

Diff (easy as, simply ran 2 ropes around under neath it (front and rear) attaching to the subframe and secured to my club lock on the other end, dropped the jack then let the ropes down slowly so it lowered the diff)

Placed a car jack (scissor) under each side of the subframe

Removed bolts and slowly let the subframe down.

Once it was at a reasonable hight I lifted each edge, kicked the jack out and placed the subframe back down

Dragged the subframe out and argggg... now for the bush removal.....

Bush removal

I didn't have enough material on hand to make a solid support for the subframe when pushing bushes out.

The 2 rear bushes are really easy as they are just simple rubber bushes.

The 2 front silicon filled bushes are a pain in the arse as they have 3 parts that need to be cut and then pushed out in succession. I tried cutting all the way through with one but the bush just didn't budge. I had to remove each ring in succession.

post-382-1172145167.jpg

It was quite easy simply drilling out the old rubber bush then using a hack saw to cut 2 small cuts completely through the metal roughly a cm apart. Then hit it with a suitable cold chisel and the metal simply peels back, roughly 3/4 the way down the bush starts to push out.

post-382-1172145179.jpg

Doing it this way they take roughly 1hr maybe a little more to remove all 4 bushes.

----

Bush Install

The 2 front bushes pressed in quickly and easily.

The rear 2 I was unable to get the press in without removing all the control arms etc so I grabbed a piece of 3" exhaust pipe, cut it down and smacked the sh*t out of it with a small sledgy. They went in fairly quickly to my surprise. Towards the end of the second the pipe began to fatigue and crush quickly with each hit.

post-382-1172146326.jpg

Bolt the diff in to the subframe before putting it back in to the car, use a trolley jack under the diff, 2 sizzor jacks under each side of the subframe and slowly raise the subframe. Easy as. :(

The hardest part about the whole thing.....

Removing those damn tail shaft bolts.

Everything else was fairly straight forward.

It’s definitely not hard and can easily be done by one person.

The subframe with axles etc all attached is light enough to be lifted by a single person so fear not peoples.

It’s really not as difficult as one (I) would think (thought). :D

I'm sure we can come to an arangement. :(

I believe you have just finished your brew. So a shortage of beers during the job won't be a problem. :D

-----------

It shall be interesting how the bushes increase NVH, especially as the R32 GTST diff's are solid mounted not bush mounted like the GTR's and R33's+

    • Hi. A little bit of an update. It maybe(hope not) looks like i would need a new tranny(it would be "maybe" a cheaper or better option anyway) So i need some info. I know i need a different propshaft(i can make custom one) LSD is not a problem cuz the engine will be still(for now) N/A RB20. So if i buy RB25DET NEO tranny...is there something else i need? I read something about push/pull type but i do not know if i need to "change" something or i can just plug n play onto my engine a go? Thanks for the advice  
    • Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance
    • My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..
    • The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.
    • Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????
