Bentley is the one I think that makes a point of saying that the rubber should get stuck to the CA. I recall they say to let it set for an hour or longer after install before driving or danger can occur.
I thought about this when I put on my Powerflex, which does not bond to the CA's. I wonder if their advice is worth anything?

I did this job today (I used a kit with the bushings already installed in new mounts) and I have to say it was totally worth it to buy a $27 three jaw puller. I'll definitely get future use out of it and it made this install very easy indeed.

This was SO much easier than OEM, also I got the plate tool from Bimmertools and it's also totally worth it. The hardest part of this job is now pulling the brace. I recommend preinstalled brackets. I couldn't believe how easy the Powerflex went onto the control arms compared to OEM!

Yes, if you replace your CA's. But not if you want to reuse them; then you'll have to pull off the old bushing.
Need an alignment after you do the job.

Here's how to test the CAB's


And to test the CA, you're really testing for ball joints.
Need to get car up in the air and use a prybar to check for looseness. Look up any ball joint test on youtube. It's universal.

If the control arm is not bent, you can just replace the bushings. I just did mine today. I'm not reading 11 pages to see what all has been said but a few points that I came across on my day in the garage:

-2002 325i
-I did not remove the frame stiffener. No problems either.
-On the passenger side, it was easier for me to remove the inner mounting nut from above with a socket, extensions and a u-joint.
-My pickle fork was not big enough to separate the LCA so I used two pickle forks at once on the same mount. This separated it enough to pop it out.
-When working on the drivers side, turn the wheels all the way to the right to give yourself more room to hammer the pickle forks. Visa verse for the passenger side.
-I installed the control bushing/mount and then slide the LCA into it. I was having a hard time installing the two 16mm bolts when it was all pre-assembled.
-I have a press that I used to install the Moog bushings into the LCAs. They went in with no issues. I only used silicone spray lube on them.
-The whole process took me about 6 hours and I've never pulled an LCA before. However, I've turned a lot of wrenches before including replacing ball joints in solid axles. It saved me $400 from buying new LCAs and mounts. I did not even bother getting shop estimates.

Replaced LCABs with OEM parts today on my son's 2001 330i. Could not have been easier:
- Removed the brace/skid plate
- Removed the bush carrier mounting bolts and angled the control arm and attached bush down to create some clearance
- Removed the carrier using a three jaw pulller. They come off with the bushings intact which was surprisingly easy.
- Fitted the new carriers and bushings using some lube on the control arm, a block of wood and a dead blow hammer to drive the bush onto the arm
- Locktite on all bolts, bolted up, torqued everything, DONE in around an hour and a quarter.

His 330 had failed a state inspection because of the LCABs. Shop quoted him $700 to replace them with the cheapest crappiest chinese rubbish available [$56/pair].

Is the rubber on the control arm bushings suppose to stick out?

I just replaced the lower control arm bushings and weeks later i notice the rubber sticks out, i just want to know if its normal?

Not typically, but we don't know what brand CAB you have there, so we don't know what's normal.
Have a pic of the bushing before you installed it?

There is not supposed to be any strain on the in and out direction.

The brand I purchased was Dorman, I don't have the pic of it before I installed it. What reasons do you think could cause it to pull out like that?

Not an expert on this

Maybe installed and let dry in one position and then the suspensions shifted when the wheels hit the ground.
Did you install with weak soap solution to slip them on?

I installed with a specialty tool for bmw e46 bushing extractor and installer, i use silicone as lubrication before installing it in, it looked good until like a month later i notice the rubber is sticking out a little. Im assuming its the brand and maybe i should of bought the more expensive oem ones. Im not sure. I don't know how long its going to last before the whole thing is cracked though.

Generally good advice never to cheap out on parts. You're already saving the most expensive part of any job (Labor), so get the job done right.
Don't think Dorman is a good brand.
If you see signs of cracking, time to replace before complete fail.
