Default Was Urgent RTAB help please, now Comedy of Errors

I've disconnected the RTAB console but the arms haven't dropped below the side skirts so i don't have enough space to remove the bolt that holds the console to the RTAB

What can I do to make the arms droop lower? I have both sides unhooked but that didn't seem to help.

Thanks.


EDIT: Note that the car has tein springs on it.

is it ok to move it into neutral and take it out of gear with it on the jack stands?

To unbolt the bottom of the shock should I just support the arm with the jack and unbolt the one bolt? Thanks!

Yes and yes. Then use a short length of 2x4 to wedge the front of the arm down from the chassis for easy access to the console/bushing.

It's a pain but doable.

well I seem to have gotten it low enough, but the existing bushings have the flange on them so the autozone rental bearing puller (C clamp) method won't really work.

I'm waiting on an e46fanatics member who has offered to let me borrow his rtab tool so I can continue.

Let this be a lesson to you and others: do not start this job without the rtab tool by your side!

I had really high hopes for the autozone rental method, but oh well.

You CAN do it with the flanges on the RTABs and the Autozone tool. You just take a screw driver and hammer and bend the flanges in so the bushing cup seats against the trailing arm. You can use a set of vise grips to tear off the flanges once you have bent them in with a screw driver. You wont dammage the trailing arm and you'll see how easy the flanges are to bend.

I explained it in more detail in this thread.

I also added my $.02 to this thread on E46 fanatics.

Also, I found a good way for dropping the trailing arm enough to work on it was:

1) make sure the parking break is off
2) I used my floor jack to lift in the bottom of the shock mount and compress the shock. This rotated the trailing arm without having to unbolt anything.

Be careful with the driveshaft, with the shock disconnected I believe it's possible to overextend the joints on the driveshaft and possibly damage it.

Why bother with the RTAB tool if you have 10 chisels, 3 extra thumbs, and a replacement rocker panel?! I can't understand why anyone would try this without the correct tool. Buy it, use it, sell it for $20 less than you paid. Done!

I got the proper tool from someone local on e46fanatics so I'll give that a shot tomorrow. Good idea about jacking up the shock to rotate things. I'm going to bolt it back up and try that since unbolting didn't really drop it much at all.
