Is that how you lubricated yours? Or did you just spray around the bushing area?

My bushings are only 14k kms old. That's very early for them to fail, especially since the originals lasted 140k.

imo doing what the guy did is a bit overkill, probably not that effective even on short term and overall, at this point just replace it.

I simple spray a shit load of chain grease on the busing. Did nothing the 1st few ride, then I spray a ton more, and this time gone, about a year ago !

But note I dont use my car often, I maybe did 6000 km since then.

Probably PB baster Surface shield should work too, this stuff is thick

Well, I guess that makes sense. Since it's noisy, that rubber boot is not sealing the bushing and water/dirt must be causing the squeak. So, it's compromised anyway already and the reason you were able to quiet it down just by spraying it over a period is that wherever it's compromised is allowing your lubricant to get inside and quiet it down. Poking a hole there just ensures a quicker lubrication then, but also faster time to have to replace it.
It's still bugging me that it failed this early and I remember that getting it out without proper toolkit wasn't fun since the brake shield is in the way... never a quiet moment in E9x ownership.

this is also my luck on some stuff like this on my german cars.

I always evaluate the effort before changing OEM stuff on jobs ''while I'm there'' knowing most of the time OEM part last longer than aftermarket.

If I remember rightly, the boots are held onto the joint with little spring clips. It's a pain of a job, but you should be able to get the clips and boots off entirely without damaging anything. Then clean, grease/lube, refit/reseal.

Yes, they have those clips. If I could do that, that may be the way to go. However, if I have to remove the big control arm to get to it, I might as well get a bushing toolkit and replace the bushing itself as I don't know whether regressing it really saves it, or just delays replacement. Rein is $10, Lemforder $20 and BMW $61.

Agreed. Go for lemforder, but send it back if it's not made in Germany.
