VY Diff Cradle replacement option ?

[OZ38]

Gidday,

Anyone here know for certain if a VY SII Calais Diff cradle will fit into a VY SI ute as a direct no modifying replacement ?

Looking at utilizing the tie-rod option on the later VY calais series II cradle as even with the 4 point camber / toe kit installed on my lowered ute I still get the inside tyre wear problem. Replacing rears every 10,000 k's approx.

Here is a couple of pics of what I mean.

Cheers

Hey Deek, having fitted a VYseries 2 cradle to a VYseries 1 car I would say that utes and sedans (and monaros and wagons for that matter!) would be interchangeable.

As long as the cradle mounting points are the same it would fit. AFAIK any track vriations between models come from different wheel offset and tyre combos.

Yeah that basically what I'm asking - Are the mounting points between VY Utes & VY Sedans the same ?

The cradles look the same from from what I can tell in the pics, but I want to be certain before trying it.

I suppose I could ask Holden the part numbers for a VY sedan cradle & a VY ute cradle.

Holden would probably have different part numbers as per usual between the ute and sedan. Could you roughly jig the car on a hoist by hanging some plum lines from the bolts in the centre of the subframe mount locations and with a large piece of card underneath plot the mounting points by marker pen?

Then invert the new series 2 cradle on the card and measure the locating points. Big effort but well worthwhile mod IMO. Series 2 doesn't even need an aftermarket camber kit if you don't go ridiculously low. Look at my VY2 Deek, rears are straight up and down with plenty more adjustment available.

This is a question for commonut

they are the same.

there is some difference between vy2 cradles early and late, but only on some.

but its not mounting related.

check out my l67 thread for all the installs of bushes etc, i spent alot of time, money and effort doing this to my car.

Thanks Taz,

I did see your My L67 thread & the effort you went to on it with the bushes etc.

So you are positive the VY S1 Ute cradle & a VY SII Calais cradle would be inter-changeable (apart from the S1 not having the Tie-rod links) ?

Also on Nicks late VY2 cradle it had some extra damping at the sub frame bush location. We cross referenced it to my VY2 Calais (albeit 03, not 04) and mine didn't have theses dampers.

Nicks car is pretty low and the rear camber is a thing of beauty, not to mention the light weight handling.

Not real sure of what your meaning by "extra damping at the sub frame bush location" ?
Is that like maybe the big round plate like bushes were thicker, or there was more (numbers) of them ?

Don't suppose you guys took any pics of that difference ?

if you check my thread you might see them.

they are shaped like a D, and are infront and inside edge near the large subframe bush.

im very surprised the vy1 ute didnt have tie-rods. in sedans its standard from vx2 onwards

I really for the life of me can't see any reason why that wouldn't go into a VP/S irs too but everyone tells my they wont, it must be seriously a case of ALMOST

I agree, Holden doesn't change shit unless they absoloutely have to. i.e. mounting points on a floor pan

[OZ38]

Oh well it doesn't matter now as I took to long finding out about if it would fit, & someone else snapped it up on Sunday complete for $500.

Bugger as things like that are hard to come by in Perth W.A. or surrounding areas.

i got my cradle for $250 (no diff).

from a vy2 calais.

i have my old cradle. it has toe links, but i had a very light knock to the side, and it wouldnt align quite, (very minor).

after taking it out, i cant see ANY damage to it. if you were in melb, you could have it, ahaha.

Yeah thats about right. This one was $200 for the cradle & $500 complete with diff, disc to disc.

I raised the question about differences in the cradles - ute to sedan on SC in the LS1/Ls2 section.

Interesting comment from a member about the sedan shockies positioned different to the ute. So there maybe a reason the cradle would not fit. Still investigating it. Plus also they raised the question of those extra mounts on LS1.

Generaly you find that the rear suspension has to be altered for utes and wagons to reduce intrusion into the load area and permit the lower floor to the tray. The sedan suspension is more upright with regard to springs and shocks because the shocks can run up beside the wheel tub, inside the boot, but you can't do that on a ute or wagon because it would intrude into the load space.

The solution taken by the factory is to lay the shocks over at a steeper angle and often involves revised or different lower mounting points.

If there were any changes on this suspension, it would probably be to shock mounting points, as the previous post suggests.

Ok recently I was told that the VY utes & the VY wagons were the same cradle. Then added to this was that VY Berlina wagons had the cradles with Tie-Rods.
Can anyone confirm this is in fact true ?
