While this may have been discussed before. It may be worth bring up again.

As all of you know these modern cars does not have grease fittings to grease the parts under the carrage.

Option 1: Do nothing. The manufacturer said it is a "lifetime lube"

Option 2: Drill a hold/tap put in you own grease fitting

Option 3: Use a syringe puncture a hold in the boot and lube.

What would you do and why? all have down sides.

Option 1: "lifetime lube" do you really believe that? The more important question will lubing it prevent the joint from going bad.

Option 2: I am concern if I drill metal parts from the drilling will go into the joint that I can't clean out. Is it better than not lubing at all.

Option 3: It is the easiest way to lube the joints but you pouch a hold in you boot. I suppose you can tape it up but.....

If there are more options that would be great.

But the way my cars have high years but low mileage. My 2000 ML only have 55K on it if this information helps.
