Ok where to start.. I found a set of 99 alero control arms for $35 a piece. These should be the aluminum ones correct? I have yet to call the place to ask if they are. If not i will call some of ther yards. Now i'm going to cut them down to j-body arm spec's. Now i also want to do the N+F+W body brake upgrade. So can i use the aluminum spindal found in the 99's with this swap? that would mean i need to use the lower alero ball joints for 99 right? Also i'm not sure on the wheels i'm using. They are 100x5 and then a bigger size but not sure as to which that is. From what i gather it is 114.5 but i'm also not using hub centric rings. So will these work with n-body hubs?
Now comes some info on the brake swap. I usually hang out on ls1lt1 or ls1tech since i also have a 95 ta. Now i was ready the N+W+F body swap and some one mentioned that the 95 calipers and brackets can be used since they are the same as impala and monte calipers. And that c5 brakes couldn't be used because of a different bracket. Well on my 95 i'm running c5 brakes.
So here is my why can't i use c5 brakes like my t/a. Don't the 93-97 caliper brackets have the same holes to mount to the spindal as the 4th gen camaro's and t/a's? On my t/a i had to do the following: Get the adapter brackets from umi null

Thank you Dave and JBO! 
so is the only thing hindering the n-body aluminum knuckles/hubs the bolt pattern and the ball joint size?
is there a way to install a 5X100 j-body hub into the n-body knuckle? i would think if you did that then all you would have to do is mod the 99 n-body control arms shorter but use the n-body ball joint.
yes? no??
You look so much cuter with something in your mouth.

yes? no??
Here are the specs for the 2000 Malibu LS which has the aluminum knuckle. Below are the specs for the hub assembly.
A= 4.921 in.; B= 3.937 in.; (C) BOLT SIZE (QTY) M12X1.5 (5); D= 2.244 in.; E= 2.295 in.; F= 1.749 in.; G= 2.894 in.; (H) BOLT CIRCLE DIA= 3.858 in.; (I) BOLT HOLE SIZE (QTY)= .510 in. (3); (J) SPLINE COUNT= 33; (K) FLANGE SHAPE= MODIFIED TRIANGULAR; KI
Here are the specs for the Cavalier hub assembly.
A= 4.921 in.; B= 3.937 in.; (C) BOLT SIZE (QTY) M12X1.5 (5); D= 2.244 in.; E= 2.295 in.; F= 1.749 in.; G= 2.894 in.; (H) BOLT CIRCLE DIA= 3.858 in.; (I) BOLT HOLE SIZE (QTY)= .510 in. (3); (J) SPLINE COUNT= 33; (K) FLANGE SHAPE= MODIFIED TRIANGULAR; KI
Notice there is no difference in the two?
I'd imagine that all the difference is going to be will be the wheel stud sizing of 5x115 compared to the 5x100 Cavalier size.
So why wouldn't the J-body hub fit the N-body knuckle?
This really has me thinking. *thinks*
I wish I could get to the junkyard to test this theory out.
If someone has tried this, please let us know.
So in theory we could have the J-body hub assembly mount into the N-body aluminum knuckle with an N-body ball joint along with an N-body tie rod end.
Any takers on this or anyone have more info on this concept?

Thank you Dave and JBO!
2000 Grand Am specs use the same hub assembly which would be identical to the Cavalier and Malibu.
So what's the difference?
I'm willing to say that someone hasn't tried to actually take a J-body wheel hub assembly and attached it to a N-body knuckle. This being the case, we could be on to a nice mod in which all we need are the parts as posted a couple of post up.
Please correct me if I'm wrong.
Thanks.

J-body hub will not fit malibu,99 newer grand am, alero, etc-- been there- checked years ago
The thing you don't state in your statistics above are that the Grand Am you got that hub assembly for is for the V6 engine. This would be normal because the drive shaft would be totally different in the design.
The specs I posted are for the 2.4 liter twin cam engine which would be the same as far as the spindles are concerned.
I've double checked this in several places and all hold this to be true.
I wouldn't want to have a hub that is for a V6 on my Cavy so why post that up?
Any other proof that the hubs for a 2.4 cylinder engine from a 1999+ Malibu or Grand Am won't fit or are interchangeable with the knuckles of the said vehicles?
The only other scenario I can figure out is that the aluminum knuckle was only used on the V6 which to be honest, has never been mentioned on the forums.
More information on this if it's out there, please.

Thank you Dave and JBO!
I've also taken notice that there are provisions for the hub to have 5x100 studs installed whereas you could remove the studs in the 5x115 pattern. Or, you could just get the wheel hub assembly for the J-body and not have to worry about it.
This has me really thinking and will do more research once I get some time at the junkyard. It rained this past weekend so I was not able to do any checking on the Beretta radiators either.
Again, more information would be great whether it's good or bad for the theories we have started here.

so what you are saying is that GM used a different hub bearing for the 2.4 engine?? instead of using the same hub for all models
where are you getting your info!!
listening
____________________________________
Primer Counts as Custom Paint Right?
BTW: This is my Sig.
This is the part number for the J-body hub and all 2.4 1999+ Malibu's and Grand Ams. National Bearing:
Part Number: 513017K
This is the part number for the N-body 99+ V6 models. Part No: 513137
Both are National brand.
The V6 will use a different tranny than the 2.4 engine and because of commonality of the 2.4 engine/ tranny combo in GM's lineup, they use the same hub as noted in the posts above.
This information comes from Advance Auto Parts but I've not checked the AutoZones or O'Reilley's.
So if this IS the case, then it's a simple swap and like ray Gardner stated, gives us the opportunity to continue with out hub assemblies with the 5x100 hubs while upgrading our knuckles to aluminum and our brakes too.
This is why I'm presenting this question to those that have done this swap for more information on what they used and why.
The only thing that would throw all this out the window would be if GM used a beefier knuckle for the V6 model that is being used for the NWF swap.
So far, nobody has disputed the information that I've presented but don't take this as gospel just yet as this almost seems too good to be true.
I really hope it is.

o reilly auto 2.4 grand am hub
all this info is in the nwf swap sticky but:
No the J hub will not fit a N knuckle. and the N hub is dual drilled for 5x 115 and 5x 110
Well after further research with the other car parts companies, I found a glitch in the AdvanceAuto parts menu.
It seems if you just change vehicles after you've already found your hub for say a Cavalier, that same hub will come up with the newer Grand Ams and Malibu's.
Chalk one up for a faulty search engine and I stand corrected.
I knew this to be good to be true and thank everyone for the corrections.
If I thread jacked, sorry for that too.
But I won't be discouraged because the NWF swap is in the plans for the 'blu.
Thanks everyone for the feedback on this.

sorry if im way off on this but wat a bout an older grand am with the 5x100 would that mabey work just a thought
ray gardner wrote:sorry if im way off on this but wat a bout an older grand am with the 5x100 would that mabey work just a thought
got a little deeper in the sticky and pretty shure i awnsered my own question they wont work
so exactly why wont the j-body hub bolt into the n-body knuckle??? im not to familiar with this area of suspension so please forgive me if its something stupid.
and really i see dont see why it wont work to do what you said, misnblu... just push out the n-body studs on the hub and put in the j-body 5X100 studs. seems to me that it should work....

You look so much cuter with something in your mouth.
z yaaaaaaa the other bolt pattern is 5X110 if i recall correctly.......
watch for flying sparks!!!
^^^ ah. thanks for clearing up the confusion. its something ive always wondered about doing.
and about pushing the n-body studs out and installing the j-body studs in the 5X100 holes? will that work?

boostNbags wrote:z yaaaaaaa the other bolt pattern is 5X110 if i recall correctly.......
because if boostnbags is right the other set (the non 5x115) are really 5x110 not 5X100 so even if you swap the studs to the other set of holes its still diffrent then the js
hmmm....
