Steeds rear subframe irs alignment kit

[Little Guy]

I’m a newbie to doing my own installs but love the satisfaction of doing something myself. The Steeda IRS alignment kit looks easy enough to install. My fear is once I pull out the cradle bolts, is there a chance that I can’t get them back in. I would hate to get into a situation that I can’t fix.

I would assume that if you had to you could use something like round aluminum stock to pry the cradle back into close enough alignment to get the real bolts started. I'm thinking soft stuff like Al so you're less likely to damage any threads. I've never had to do this, it's just the direction my own first shot at such a situation would take.

Using a transmission jack would probably be a better idea than a general-purpose floor jack.

There is a hole just next to where the bolt goes in on the rear(on the "bracket" ). There is a hole in the chassi as well.

If need be you can use those to pry the subframe into place.

How do I know.... I did it today

Thanks for the tips. I just don’t want to call a mobile mechanic if I mess something up.

Are there any benefits to installing this on a stock car?

Just do one at a time and see how it goes. If yours is already in alignment, then the bolts will go right back in. If it is out of alignment, then just loosen and not remove 1 side at a time and then pry the whole cradle as needed to get each one started. I felt the same way before I first went in there to do it and had 0 issues. All my bolts started right back up and I have had them out 3 separate times now, with and without pins.

Don't forget to support the cradle before taking the bolts out.

No, none.

Don’t drop both sides of the subframe at the same time if you don’t have to. If you only drop one side at a time, the subframe will stay it it’s original alignment. Doing work one side at a time is the easiest way to avoid subframe alignment issues in the first place, and you can do almost any job one side at a time, including removing the entire rear control arm.

No, none.

Unless your subframe is off from the factory and your wheels don't line up side to side. Probably not as noticeable with stock wheels being how tucked in they are though.

Thanks. I plan on lowering the car soon tho. Will it be needed then?

By "support the cradle" you mean a jack under the differential? I assume loosen both sides and only remove one bolt, do the job and move to the other side. Then torque them up when you are done?

edit; I'll be adding mine with the BMR kit and GT rear sway bar.

It's not really a "needed" part for anything, but it is complimentary and ensures that your cradle goes back centered which is a good thing.

@dguzzi
I supported the right side with a jack placed in between the front and rear bolt on the cradle.

Then loosen or remove only the right side cradle bolts. If needed slowly lower the jack to give yourself enough room to slip in the bushing. Rear ones can suck to install one side took me a hour to slip in otherside was instant.

Jack the subframe back up, but be careful it may not be flush to the car and you might start jacking the whole car off the jack stands. Insert bolts and tighten to suck the subframe back to the car. Then repeat on the other side.

Could that strain the left side bolt? Maybe bent it slightly buy lowering the right side to much? Thanks for the reply, I'll be doing this soon!

I dont think it will bend the bolt, it's a thick ass bolt. Just dont just let one side hang, lower the jack and if you go to far and its hanging just pump it back up until you connect. I've had mine hang for a while and had no issues. Theres a YouTube video from CJPP on the install, they also do it this way.

I also took my wheels off so I had more room which will also take some weight off if your concerned still.

I also had to remove my catback to be able to lower the cradle far enough.
