bmr cb005 install question

[Bartly]

So I was getting ready to install my cradle support and was hoping to pull it off without an alignment by keeping some of the bolts tight. After removing one of the large bolts I saw that my cradle is not centered very well at all. The bolts look to be shifted to almost the worst non centered positions. Guess I will be needing an alignment after all. Figured I was going to order some of those Steeda centering pins and re do it when I get some more time. I was kind of confused on where to support and jack the cradle. Seems the only way to really center a jack under there would be to lift right on the differential, but didn't know if that would work very well. Where do you guys lift and support the cradle. I was looking and saw the harbor freight cross beam thing that attaches to a floor jack and am considering buying it to support the cradle on the beams left/right of the diff. Anyone used one of these or have a suggestion on where to lift/support the cradle.
Another question, if I do end up installing the Steeda pins, in theory, would I ever need to have the rear aligned again after any other mods down the road. Kind of thinking that it would be fixed and shouldn't ever need an alignment after the cradle is centered?

Thanks for any suggestions/comments.

Thanks.

The bmr piece centers the cradle... No need for steeda parts. I raised it from the diff and used Jack stands on the pinch welds in front of the rear wheels.

CB005 will center it for you, its built in

Okay, thanks guys, saved me some bucks on he Steeda parts. I saw that the front braces look like they center the front end, can't recall if the rear pucks did the same for the rear bushings.
So sounds like it's okay to just put a jack under the differential housing to raise/lower the cradle as needed, wasn't sure on that one. Didn't know if that was okay for he diff bushings. Saved me some bucks on the harbor fright thing too. Thanks!

BMR CB005 = Steeda IRS support braces + steeda alignment kit + steeda IRS bushing support system

Nice, I should be good to go. Appreciate the info. Can I ask did you lift/support the cradle at the pumpkin too?

Since you're centering the front two points, and the cradle is one piece, you have the rears centered by default.

Question: is there an issue setting alignment specs on a misaligned / less than square sub-frame? The idea behind the BMR and Steeda solutions depends on the fixed subframe mounting nuts in the frame being centered. This hasn't been true in all cases. That's why some folks are having to manhandle the subframe back in. The factory alignment process depends on aligning the centering holes on the frame with the centering fittings on the rear of the subframe using a fixture of some sort. This approach eliminates the need for high tolerances in how the subframe mounting points are fixed in the frame (cost savings?). The one thing the BMR and Steeda solutions will do is give you a consistent alignment of the sub-frame. Hence my question. I'm running the BMR Delrin bushings and that subframe is solidly fixed in position. But if the subframe is not square to begin with not sure if that could be a problem for folks.

i lifted the rear by the pumpkin with a low profile jack and a hockey puck

I tried using the Steeda centering pins with BMR CB005 and they won't work together. I put the back two in then cut one in half to put in each of the front holes. If I put both in I could not finish installing the bracket so I only used one. Several months later I not have weird wear on one of my rear tires showing I have positive camber. I am actually going out to the garage in an hour or so to remove the three remaining centering pins and then I will be dropping the car off for an alignment.

I installed my CB005 kit this morning.

Some notes to make installation of the CB005 kit a whole lot easier:

Follow the BMR instructions regarding loosening/removing the 21mm subframe bolts and supporting the cradle.

USE A COUPLE OF WRATCHET STRAPS TO HELP GET THE CRADLE ALIGNED, AND JUST AS IMPORTANT, TO HOLD IT IN PLACE.

After installing the BMR upper bushing cups, I then partially threaded in the two 21mm subframe bolts, front & rear, without any of the lower BMR parts, so I could see how badly the mounting holes on the cradle were mis-aligned. I used the wratchet straps to move the cradle so that the bolts were centered in the cradle mounting holes. I then removed the bolts, and installed the BMR rear lower bushing lockout & front cradle support.

Doing it this way allowed me to easily hand thread the 21mm bolts (you can use your pry bar in one hand to easily micro-align the holes so the bolts thread in nice & easy with your other hand). No need to fight getting the cradle lined up.

Once all the BMR parts and all 4 of the 21mm cradle-to-frame bolts are installed, and the cradle is lightly tightened back up to the frame, then start installing the 4 front 13mm bolts, using the pry bar if needed to micro-align the front cradle supports so that you can very easily hand thread all 4 of the 13mm bolts into place.

Finally, torque the 21mm and 13mm bolts down per spec.

This process makes the installation so much easier, with no sweating, cursing, or cracking knuckles.

Thanks for the replies and all the info.

Is this something that can be done by the mechanically challenged? I installed a strut tower brace, steeda irs braces, and BMR CB006 myself but this seems to be in a different league. Thanks!

You will have to get it aligned. I installed mine and took it straight for an alignment. The thrust angle was over 3 degrees so my car was now essentially crab walking down the street. Get an alignment.

This made me laugh way too hard haha
