CAB's failure after 10k miles ECS

Hello fellow fanatics, I purchased these control arm bushings from ECS along with other parts, however these ones as I looked at them when the car was lifted I found the red part sticking out of the bracket. I also hear cracking noises at turns as if I had a messed up axle on a FWD car. Has any one experience this before with this kind of CABS, do I need to buy new ones now or just replace the internal parts with new set from tuner motor sports, is it risky like it would totally come out and I loose control of my car. Any help would be appreciated guys. ECS I would like to hear from you on what's the warranty on this product. I'd ont track my car and I don't drive aggressively.

If I buy this set http://store.bimmerworld.com/powerfl...hing-p281.aspx, can I press it in the stock housing I took off when I replaced by the above mentioned CABS.

Simmer down man, its a Sunday, give it time and people will respond.


To answer your question; yes and you'll need a hydraulic press to do it. I went with the Rogue Engineering bushings for my FCABs and love them but anything is better then broken ones. I hear good things about Powerflex too.

Good luck and get them replaced ASAP

You can press out the old bushings and reuse the housing. It is very difficult though and you'll need a press or special tool. You can get powerflex prepressed into the housings for $150. I bought mine from Bimmerworld too and I have no problems. (Powerflex).

You know it is possible to install the bushing too far onto the control arm. There is a certain distance you are supposed to slide them on (at least for the OEM rubber ones). I simply slid mine on so that only a small bit of the control arm stuck out the back.

Just to clarify since you have a 323i, which type of control arms have you got? #5 or #6?

The bushings you bought look like they are made for the new type of control arms (#6)

hopefully you didn't stick 66mm bushings on 60mm arms. i dont think the fitment is the same. either way, i'd probably not trust generic poly stuff. if you must go poly, choose a name brand. though honesty id recommend meyle hd

Meyle parts are the worst car parts Ive seen in my life. Their hydrobearings dont even have fluid inside. Therefor -> no hydrobearings. Just buy the original parts made by Lemförder. They are the best you can get.

I don't know which one i have , and when I changed them I took the old cabs completely out n replaced them with the on in the first post, red n black, I guess I'll do the power flex ones since I have a stock housing, ill measure before I order. Thanks for all who replied though with their inputs, I appreciate it

I have heard about lots of problems with the poly ones. I have also heard a lot of people who swear by them.
The Meyle ones are sort of similar, lot of people swear by them but you also hear a lot of people complaining about defective ones.

I rarely if ever have seen anyone complain about the Lemforder ones though, they may not be the best but they are certainly the most consistent.

If Lemforder is OEM, then everyone complains about Lemforder. They are destroyed after less than 50,000 miles.

I think most people complaining about the Meyle HD ones do not install them properly. They must be slid on the control arm a certain distance. If you put them on too far, they will get ripped out. You also have to wait for your lube to dry up (used to slide them on) before driving.

Poly bushings are pretty much fool proof. I have Powerflex and they have been great so far after several thousand miles.

I think you are right. It is possible to make mistakes installing any CAB, poly or conventional. I put some Meyle HD CAB on my car and absolutely love them. The front end is tight again. Best $79.00 I've spent in a long time.

If by consistent you mean guaranteed to fail in <45,000 miles, then yes, they are consistent.

Well - then I guess either american roads are much worse than german roads or the parts on export cars have a lower quality than those used on cars for the german market. Of course - you can also be wrong or you have simply exaggerated.

I changed mine at 100.000 km (about 62.000 miles) and they were not destroyed nor leaking at the time - just a bit soft. I know a whole bunch of poeple who have 150.000 km (about 93.000 miles) on the speedo and they still run the original hydrobearings that came from the factory - not destroyed nor leaking.

Say those bearing make it to 60.000 miles -> thats the cars halftime. I usually change all my shock absorbers and bushings and stuff (hydrobearings) after 60.000 miles. After all - those are wearing parts. How long do you expect them to last?

Go to e46fanatics.de (german site) and people will tell you that Meyle Parts arent just cheap but also really really bad (they ought to know). IMHO - Meyle is not even a manufacturer...

BMW engineers designed the hydrobearing as such for good reason. Without the "hydro" (like on Meyle HD parts) those bearings dont work the way they are supposed to. On e46fanatics.de there are lots of people who have complained about those Meyle parts. They dont just make the ride stiffer - they can also cause the steering to vibrate and so on. In my opinion there is no better BMW parts manufacturer than Lemförder. Go to any german BMW forum and thats what people will tell you.

Lets be honest - people only use PU bushings and Meyle parts because these parts are cheaper. Anyway - there is a reason why PU bushings and Meyle parts are mainly sold on ebay...

How about all the complains from people who buy the whole thing (Meyle control arms with hydrobearings already installed)?

Been there - made my own eperiences - dont believe in PU bushings anymore. Ive seen Powerflex bushings fail after a few thousand miles -> deformation due to overheating -> yes Im serious.

Our roads may be worse. I know our highways are much rougher than your Autobahn. With a 70 mph speed limit, there can be bumps and some potholes in the road without killing anyone. I also doubt the quality is different. They are identical parts between exports and cars that stay in Germany

I changed mine at 100.000 km (about 62.000 miles) and they were not destroyed nor leaking at the time - just a bit soft. I know a whole bunch of poeple who have 150.000 km (about 93.000 miles) on the speedo and they still run the original hydrobearings that came from the factory - not destroyed nor leaking.

That's honestly not believable. I bet their cars drive horribly and they don't even know it. I had 65K on my car and it needed RTABs, FCABs, and a steering flex disk desperately. I put on new control arms too.

Say those bearing make it to 60.000 miles -> thats the cars halftime. I usually change all my shock absorbers and bushings and stuff (hydrobearings) after 60.000 miles. After all - those are wearing parts. How long do you expect them to last?

Longer than that. My father has a Lexus GS300 with almost 150K on it. It still drives very tight and he hasn't done any extra maintenance to it. The E46 suffers from accelerated bushing wear. There is absolutely no denying that. Most car's shocks last 100K miles and that's what is expected.

Go to e46fanatics.de (german site) and people will tell you that Meyle Parts arent just cheap but also really really bad (they ought to know). IMHO - Meyle is not even a manufacturer...

This makes no sense. Why would a German know more about these cars than us? Also, Meyle is a manufacturer. That isn't a matter of opinion. Some of their other parts are suspect, but their bushings have a good record.

BMW engineers designed the hydrobearing as such for good reason. Without the "hydro" (like on Meyle HD parts) those bearings dont work the way they are supposed to. On e46fanatics.de there are lots of people who have complained about those Meyle parts. They dont just make the ride stiffer - they can also cause the steering to vibrate and so on. In my opinion there is no better BMW parts manufacturer than Lemförder. Go to any german BMW forum and thats what people will tell you.

BMW engineers designed the oil filled bushing (it is not a bearing) to absorb vibration to reduce road noise and feel in the cabin. Meyle's and PU bushings simply stiffen it up at the cost of noise and vibration. It's not like this is hurting the chassis.

Lets be honest - people only use PU bushings and Meyle parts because these parts are cheaper. Anyway - there is a reason why PU bushings and Meyle parts are mainly sold on ebay...

PU bushings and Meyle bushings are sold on almost every single parts site on the internet, not just Ebay. I would also be willing to bet 90% of people on this forum do not buy theirs from Ebay.


How about all the complains from people who buy the whole thing (Meyle control arms with hydrobearings already installed)?

I don't know. Show me some of those complaints. There aren't any recent ones on this forum at all.

Been there - made my own eperiences - dont believe in PU bushings anymore. Ive seen Powerflex bushings fail after a few thousand miles -> deformation due to overheating -> yes Im serious.

Whoever had theirs deform did not properly grease the bushings then. I drive on some of the roughest interstate roads in the nation and I have no problems with Powerflex FCABs or RTABs. My car is louder, but I don't care.

Those are the MTC Polyurethane Front Control Arm bushings (LINK), they carry a one year warranty from time of purchase. Shoot an email to customerservice@ecstuning.com and they'll get you taken care of.

Did you grease the poly bushings prior to install? If not they do have tendency to make noise under all driving conditions.

Thanks for chiming in, I did grease them and they were fine when first installed until recently they start doing that cracking noise like I mentioned a broken FWD axle noise and sticking out from the black part. too bad I’m past the year but I will post a pic of how they look now may be someone will tell me what should be done, as of now I ordered some powerflex and I will press them in the old OEM housing I got..
