Its pretty simple, do you want to know what size wrenches you will need?

be careful with the old springs, they are dangerous if your not careful, other then that its a matter of taking the old one out and bolting the new one in

Thanks Hollywood. That will be helpful.

You know guys it was a serious question. I didn't know if I had to worry about my front end allinement moving. Or things like that. I thought asking on this site I would get good honest advice. But unfornately I seem to get a bunch of wise remarks. I am sorry if me asking a question about doing I have never done/seen done is to belittling for some of you to take seriously

To everyone that has given serious advice....I want to say THANK YOU

okay then I apoligize....guess I read it the wrong way. I tought it was made as a sarcastic comment...so I am sorry.

just having a bad day.

I would want alll the help I can get.

is it really as easy as unbolt and bolt up the new one? Do I need to worry about exact placement when I put it back? I ask because the bolt holes are elongated.

The K-member bolt holes to the frame only goes to side to side, It does not go forward and backward,

it is easy as unbolting the old one and put new one in, If you are using stock arms, It might have an interference with your k-member, you will need to grind off some metal on your stock control arms.

I have also heard the control arms bolt do not line up well, The link i gave you the guy actually took the time and grind off the supplied bolt, but you can always go get same size bolt with smaller washer from hardware store, Make sure they are grade 8 and above.

I personally have AJE K-member and install was very easy. While doing your K-member, do the oil pan gasket if it's leaking and other little stuff, look for thing that are worn out and out of order, you are going to be under the car for a while so make the time useful :)

Good luck:nice:

Yes you will have to have an alignment done on the car after the install.


IIRC the control arm bolts are grade 10.8 not grade 8.

Here it says 10.9, but I think that's a typo.

FWIW if they are anything like mine you'll have to replace most (I replaced all) k member and a arm bolts. The salt rusted half of them through, and several snapped in half upon removal. They're not cheap, but might as well do it right the first time.

I'd say thats a good thing and a bad thing, its good cause there is nothing in the way. Its bad because the old springs become more of a hassle to remove. When you try to jack up the a-arm its just gonna lift the whole car up. The hardest part for me was getting the old springs and a-arms off. The stock springs make me nervous

You can take the whole assembly out in one piece, However you will need 2 other friends to help you out.

But since you are using stock arms, I suggest you take out the springs and arms with stock K-member still attached to the car.

Why does "Stock" springs makes you nervous? I usually lower the control arms slowly with small hyd jack and pop them out :) It never shot out at me, lol

Good luck :nice:

I did myne with the strut still attached and it didnt go so well, i ended up getting hit in the head with the jack handle, i just dont like messing with them, crappy design and they are definitly dangerous, they store a ton of energy. Im glad i switched to coilovers so i dont have to deal with that nonsense. The jack method would have worked for me if the motor was in the car, but without the motor, even the slightest tension with a jack cause the car to move off the jackstands

:stupid:

**** the stock springs, those piles of **** are just that, when i was taking my car apart i got hit in the ****i chest with one of them, and people here are saying that you need 2 or 3 or 4 people blah blah you dont, i built my entire car by myself, just attach everything to the k member before you put it in the car and everything will work much easier
