Thanks Michel,

That is what I was planning to do.

New Lemforder with bushing. The balljoint should last about 80-100K (depending on driving style/road condition).
- If the Boge bushing is gone in 40-50K, then I will remove the arm and insert new bushing.
- If the arm lasts until 80-100K, well then another Lemforder thrust arm goes in.

By the way, the second picture in easyover's DIY is just a scrap piece of steel you need to push the old bushing out. I used a 1.4" thick piece of flat steel for mine."

They had some problems with their older design which were purple in color and softer than the newer, black versions. I had Powerflex on everything possible on my M3 and never one problem. I have had PF on my E39 for around 25K and no problems. They do need lubrication every so often, but this is negligible for the upgrade in steering response and overall feel. Also, from the post above, if that poster only installed one washer then the installation was not correct. So, you cannot blame the premature failure on the bushing itself to be fair - it is a result of improper installation not allowing the bushing assembly to do it's job properly. There is a way to install them with both washers, they just did not do it correctly.

My only complaints with poly bushings is they get very hard. If your weather gets cold at all they turn to rocks. Personally, I don't think they are necessary on a daily driver E39.

TRW is OEM and is just as good as Lemforder. You'll even find the same ball joints in some of them so there is not way you could feel a difference. I'd take the TRWs with HD bushings over Lems with OE bushings any day.

There are really too many variables to say. I started getting symptons of failure at 35k miles or so...but did not get a proper diagnosis until about 60k, and have them replaced with more oem. Have 122k now, so over 62k miles (with original ball joints!) and I inspect them everytime I perform an oil change or other service...they look fine so far. (knock wood)

Too many variables. I'd say MOST see some sign of failure at least by 30k.

So far everyone has been loving the OEM arms with the HD bushings. I wouldn't be scared to run the TRWs. Max is right, TRW is OEM on a lot of BMW parts. I sell a ton of them and have had zero complaints. I only have the Lems on the site because there are a few that still want them.

Pressing the bushings is a PITA and time consuming. You also run the risk of destroying your bushing and/or arms. If I could buy arms without the OEM bushings then I'm sure they'd be cheaper. What you are basically paying for is 2 sets of bushings. The OEMs I have to press out and then the HDs I press in.

Are the OEM bushings Lem's?

The bushings themselves are made by sachs/boge.

It seems a bit silly to be concerned with after market bushings if you do not have aftermarket springs or shocks or other such suspension pcs.

And even if you do have mods like above, like I have, I can not see a good reason to go to the bushings.

This is just my opinion. If you feel differently then go for them

The reason is not to supplement mods, it is to prevent the early failure. These are not poly bushings.

I personally like the thought of a thrust arm bushing that lasts more than say 20k miles- call me crazy.

Crazy!

LOL!

I can not see why there would be any question to these Meyle HD bushings...

Logic and common sense says these bushings are better than the OEM bushings.
But, there I go thinking again...
Don't tell my wife...

I've got around 220K miles and I'm on my 2nd bushing replacement, which means its the 3rd set in my car. I expect to get 80K miles per OEM set.

You can run them to 200k if you want. They are just shot far before then.

I'm not talking about supplement mods.

I'm saying that its silly to change to another brand of bushings if you have no other mods. If your suspension is stock or very close to stock then use the stock bushings. That was my point.

But hey, go knock yourself out if that suits you.

You seem to have a problem getting the point. I did not suggest to run them to 220K. My point is to share that I'm on the 3rd set that my car has seen, and that I am getting around 80K miles per set.

Simple.

You obviously didn't read my post. I never said you ran them that long. I said you could run them to 200k but that doesn't mean they are still good. Since this is not an imminent failure part it is hard to tell when they are gone. You're just keeping a worn out bushing in there until 80k and then replacing it. Doesn't mean it is in good shape. I'd like to see one that had 80k on it and wasn't cracked missing its fluid.

This is the same thing as when to judge your struts are shot. People usually run them FAR beyond when they are worn. That doesn't mean they are lasting that long though.
