jacking an R33

[(B1) MR_fanny]

yeah ive buggerd my rails too using a trolley jack and theres no way of gettin it back to orignial for too...sigh. i was thinkin of making an insert on a lathe to sit in the trolley jack to make it fit like a normal jack.

as for jackin points....the manual says diff and crossmember.

[supra]

all rails are stuffed i was told, as it comes into aus, they use folk lifts to get them off the carrier. i don't know, don't quote me for it!

[(B1) MR_fanny]

mine were factory perfect untill i went at them with the trolley jack.

supra,

My rails certainly aren't stuffed and I refuse to stuff them myself.

I refer to my earlier post if you are doing an oil change, by running up on one car ramp sideways !?

If I had to jack it, it would be by the crossmember /diff as mentioned by others.

ok, my bad! mine are stuffed =)

This is another manifestation of analness and stupid arguments with no evidence to back it up.

Those of you who say you are wrekcing the structural integrity of the car - do you actually know what the sills do? the little thin metal flap will just get flattened onto the sill. The sill itself does not actually get damaged, just the little metal flap gets bent. Have you actually felt it? it is so thing and weak and it does almost nothing.

I'm not saying jack up by the chassis rail, because that does get bent, and that is important. If the fatory jacking point it the sill, then it can take it. Does the standard jack bend the sill? NO! therefore by jacking it by the sill, the only thing you bend is that stupid flap that does nothing.

Besides, like i said, a lot of car garages hoist the car by the sill, and that flap does get flattened. Skylines are not special in this sense. All cars have that little metal flap and it gets bent. If you went up to your parents and told them about that on their car would they care? NO

:werd: I think you'll find *any* shop with a hoist lifts your cars by the sills. Some places put rubber pads where they lift but thats just how hoists work.

Floor jacks on the other hand should use the diff, gearbox or engine crossmember or a suspensions mounting point

um, that is what we were talking about wasn't it?

Scary Story!

I have got a 1350kg trolley jack which the handle was so short that I can't even pump it outside the car. (as in the handle's length is still can't be seen if you look from the top of car down). I've got it in the air how ever, it's extremely hard to lift it very high. I used normal jack to jack up more, then trolley up again, then jack up again then trolley until the stands fit under the sills.

At this point, I placed the stands underneath each side's sill. and let go of the trolley jack, but oops, did it too fast with the release hydrulics... the car thumped down on to the stands! made a loud noise!!!!!! i was so freaked out!

i thought it stabbed right through the cabin or something!

But it didn't, I was pretty sure the gap b/w the stands and the sills weren't more than 2cm! I had real trouble getting the stands underneath the sills in the first place. When I did, there was hardly enough space for me to place a piece of wood in.

I realised the noise came from the metals hitting each other, as in the sills and the stand, there was no visual damage!

Can you guys tell me if there will be structual damage?

The reason i am jacking the car up is for service, change oil etc.

after this incident, I dropped the car back on ground! scared it would have done more damage! I found that I don't need to jack the car up for me to get to the sump plug, how stupid me!

=( Still shaking from that noise, it's like, ****, there goes my car!

Amazingly no damage noticed!

[supra]

and yes I did use the trolley to jack at the front cross memeber! with a block of wood, hardly any noticeable change after it's down.

But take my advice, do not purchase the 1350kg jack from super cheap auto! the handle is too short, go for the heavy duty ones... like the next grade up! i fink this trolley jack is for little starlets! not skylines!

any one can suggest a good trolley jack with a longer arm?

[predator]

sounds like you weren't careful enough with the release screw do have to be careful other you are right.

you generally always have problems with the big chunky one on lowered cars, even worse with a bodykit. I have great trouble even getting it under my sideskirts. And front similar story of getting to gearbox cross member due to 400R bar.

You can get a special "slim-line jack" which is better suited to our sorts of cars, but can cost a fair amount. I guess you only have to buy one once though and you will always have it.

[supra]

so was it actually alright to use a 1350kg trolley jack the whole front of the car? or is that already going overboard, cause I already heard noises from the trolley!

[predator]

yes it should be fine.. remember the actual jack load will be less than 1350kg as you are only jacking one, or at most two wheels. The rest of the weight will be distributed to those other points as the car is jacked.

You just have to make sure that screw is tight as buggery when you go to jack it up.

I also use a supercheap auto jack :Oops:

[Duncan]

fatz also had one of those super cheap jacks, we had my GTR up on it and the jack twisted, bent and dropped the car.

Also inconvenient coz we didn't have another jack to rescue the bent jack from under the car. Not happy.

As for 1350kg, that should be heaps....how many wheels lift off the ground when you jack a car. The jack's only holding all the wieght if all4 wheels are off the ground

I'm currently getting one of these, $315 delivered.

[wrxhoon]

dont buy that $ 30 rubish they are dangerous !! i've seen them twist and the car just drops .

spend like 150-200 and get a proper one ( still a cheapie ) i use proper commercial jacks that i've had for 20 years and still going strong ( i've changed the seals though )

supra dont put the stands under the sill put them under the rail you wont bend that .

the jack that comes with the car you put under the sill cause its made for it . and its only meant to be used to change a flat tyre thats it .

you say you can get under the car to undo the sump plug , sure you can but what about checking things like gear oil , cv boots , uni joints , oil leaks and what ever you got to jack the car up to do a proper service its much easier and you dont want to use el cheapo stands either ( made out of 1.6 mm steel ) they are to flimsey .

[wrxhoon]

duncan ,

are these alloy jacks ?

[supra]

wrxhoon, yes, i take your word for it mate! it didn't sound right as soon as 2 wheels are off the ground, the spring was like , grung grung grung, gurnk ... and i can not lift it any more!

it was so hard to pump it cause the stupid handle wasn't long enough! god damn! I just hope there wasn't any structual damage to what I did today! =(

[supra]

duncan: can i borrow it , haha

or even have it!

=)

j/k

[(B1) MR_fanny]

any industry trolley jack thats worth about 200 or so will do the job. compare that to 25bucks from someplace like supercheap and it pretty much answers all questions:D

yeah i agree that bending those flaps will do shiit all to the integrity of the car but boy do they look terrible when u do bend em.

and yes u dont need to jack the car up to change the oil:D:D
