Clunking after putting on Meyle HD control arms and bushings
 
My original bushings went bad (~80K miles), so I replaced them with Meyle HD control arms + bushings. Soon after the Meyle were installed, the front suspension started to develop a metal clunking noise that can be heard and felt (through the floor board) on both sides. It also can be heard outside. It sounds like a metal-to-metal pop/snap.

The noise is mostly successfully reproduced by turning the steering wheel when accelerating/decelerating. Sometimes an abrupt take-off in a straight line can produces the noise too. However, going over bumps does not produce the noise.

I have searched intensively and extensively in here and other BMW forums. Two of the most helpful and relevant threads are these:
http://www.e46fanatics.com/forum/sho...d.php?t=490479
http://forum.e46fanatics.com/showthread.php?t=587245

I had couple BMW techs inspect the suspension. Nothing could be identified as the culprit. However, as BMW techs, they don't like any part that is not OE. In one occasion, while car was driving off the edge of the garage floor to the pavement (steering wheel turned), we could hear the clunk coming directly from the area behind the front wheel. We have inspected the tie rods too. They are fine.

I contacted the vendor. While they firmly refuted the theory that Meyle causes the clunk, they admit once or twice a year, out of the hundreds of sets of Meyle arms they sell, a customer would report such a problem. They attribute it to install error and the notion the improved/tighter ball joints/bushings would exacerbate the symptoms of the weak links in the suspension. With that said, they are willing to give me a full refund.

It's about 3 months now after the Meyle went in. The clunking has gotten worse. I now also have a steering wheel shake between 60-70 mph. When I take my hands off the steering wheel, I can actually see it shimmying.

I am without a job right now. Therefore, I don't have the money to follow some of the members who replaced strut mounts, struts, brake calipers, sway bar bushings, namely the whole suspension, to chase down the root of the problem. What I have decided to do is to buy a new set of OE control arms and bushings to put back in, and then ship the Meyle to the vendor. I believe it's the most financially feasible move at the moment. Hopefully it'll return my suspension to good form and ease my anguish.

probably the struct bearings are bad?

Did you remove the end links at all? If so go back in and tighten them again. Even if they feel tight with your hand get your wrenches out and do it.
You'll need two wrenches. One to hold it while you tighten.
13mm I believe.

So many Meyle went bad stories on the forum lately... not saying it's your Meyle parts that's causing it... just really making me want to go OEM forever. :(

Is this good or bad?

It's your endlinks. Tighten them well. You may need a zap of an impact wrench if you can't do it by hand.

As far as your shimmying goes, you need to get a good balance job done with a place that has their machines calibrated regularly. Not all balancing jobs are equal. You also need to remove the wheels and lightly sand all hub to wheel mounting surfaces. They need to be perfectly clean. You aren't using cheapo aftermarket wheels right? And tires, what condition are they in?

I assumed I would be auto subscribed to my own threads. Apparently not...

E46Mango, brand new OE end links had been installed while trying to pinpoint the problem. The clunk was the same before vs after.

Last night, a new set of Lemforder control arms and bushings went on the car. The clunk went away immediately! The whole front end is now quiet as a mouse. It feels tighter too (which may be subjective). The day before, I followed the advice of balancing the wheels. That cured most of the steering wheel shimmying. With the OE control arms/bushings installed now, the shimmying is virtually gone.

My car is back ^_^ Alignment is in order tomorrow morning.

This experience made an OE(M)-only believer out of me, especially when your financial means are stretched. Thanks to Max @ oembimmerparts for his understanding and commitment to customer satisfaction, I was able to return the Meyle HD.

Tex323GripIsKey 05-17-2012 05:16 PM

Yeah man I ordered some stuff w max, he didnt have crush washers on his site. He threw them in for free when I contacted him on FB!!! Great service. That guy is on to something..

Mango 05-17-2012 05:48 PM

Yep. Got my Meyle HDs from Max. They've been perfect.

Just curious, were you able to identify any play in the ball joints or anything else that might have been causing the noise after you had the Meyle parts off the car?

I got the same clunking after installing Meyle HD bushing. After 2 days triple checking everything I did; torque everything to spec over again; and checking forums to identify what did I do wrong?
The problem boils down to Meyle bushing design is not same as the OEM. The Meyle bushing outer metal cylinder where the control arm is inserted, the edges are not slightly bent out as the OEM. The control arm and the metal cylinder touch every time I hit a bump. I will replace with either a polyurethane version or OEM (not sure yet). BTW, I did a temporary fix to this by cutting pieces of the old bushing rubber and inserted in the open gaps between the metal cylinder and control arm (it's holding really good so far).

Check your caliper clips!! After I did my entire front end suspension, I had the same noise. I had a bad caliper clip

I'm guessing End Links as well.

17mm or 16mm depending on which brand you have.

OP, make sure to safely get both wheels off the ground before you tighten the end links...while you're there you may as well take them off, and inspect the ball joints on the end links (they should be pretty firm, a blown end link will be floppy), and will need to be replaced.

Good Luck.

Steering rack coupler?

boyguan 11-27-2012 02:07 AM

On my car the bolts for the lollipops came slightly loose and just needed a turn. Could be the loose splash shield

WDE46 11-27-2012 06:04 AM

Guys look at the OP date...he solved it already too.

Bad quality control on the Meyle HD parts seems to be the issue here. I would bet a second set of Meyle HDs would be good, but I understand not buying another set and just going back to OEM. My Meyle HDs are great.

I am experiencing the same issue of a "clunking"sound during speeds of 70+and turns.

Recently replaced both control arms and the right one is secure yet the left one is able to move up & down.

Retorque your bolts.

Place a block of wood directly under the balljoint you are tightening then jack that block of wood up a decent amount to get some weight of the car on it. Then torque the nut. i hope you're using genuine bmw nuts (brand new) i think the torque is around 48 ft lbs. (don't quote me on it though)
