Also looks like you pressed the top bushing frist using the lower upside-down correct?

I don’t think he answered this part of your question but I believe that’s what he did. Looks like it to me anyway!

I want to tackle this soon myself!

I did the BMR cradle lock out kit. Seems to help on track. I'm sure not as much as the solid.

I did tops first to make sure they fully seated. In the rear there was a tiny gap and imo it's best for the gap to be on the bottom.

It's not a hard job if you have the right tools, took me and a friend about 5 hours to do that, new brake lines and a couple other little things, was on a lift with 3/4'" drive impact, both help a lot.

I would assume any gap up top would go away after driving as the entire weight of the car presses back onto the subframe. (Requiring retightening of the bolt too)

If there’s gap on the bottom, I would imagine an impact gun would take car of that…. Or maybe jack the rear of the car under each bushing one at a time. The 2k weight should press that bottom bushing in.

This is all speculation of course!

Yeah, that's incorrect. As I said, we had a 3/4" impact, it's used to work on diesel trucks... The bushings meet just before the shoulder of the 2nd bushing pressed in hits the subframe, so the gap is permanent. The force required to press these bushing in far exceeds the weight of the car on the bushings, so if the gap is on top it will remain there, the install is permanent.

Interesting that they touch before mating against the subframe. Thanks for the explanation. Really good to know!

That means if one were to install the bottom first, you’d inadvertently have a lgap on top which translates into greater wheel/fender gap plus throwing off suspension geometry a tad. Correct?

Whether to install the top or the bottom bushing flush has been discussed many times with strong supporters on both sides.
The instructions that came with the kit I got state to install the bottom bushing first. IMO this mimics the rubber bushing installation, its flange is flush on the bottom side of the cradle also.

I do believe it doesn't make much difference, because they are in place very tight and most likely will not move.

Instructions attached, step 45, pg 11

Just installed the bushings! Almost gave up at one point!

Still have to put everything back together. I’ll try to put up a video and images for there to reference. Really hope this upgrade is worth it!

Btw, why do my links not work with a preview. Obviously doing something wrong! Lame

For previews to work, need to post links with the full address like www. youtube.com/whatever

Nice videos. I dropped the whole cradle to the floor, while leaving the driveshaft connected, and used pullers to push the bushings out, and used the same method to install the new ones. I was a chicken about the torch, but that method, probably, saved 5-hours I bet. I think either the front or rear bushings are hydraulic or something though... Regardless - it's obviously affective, and has been done several times with no reports of big issues.

Thanks bud! I contemplated dropping the subframe but didn’t want to disconnect the LSD coolant lines and such. I felt more comfortable using the torch with some tin foil to protect nearby wire harnesses
