A grease needle.
Yep, a big bore hypodermic needle, mated to a grease nipple. It fits on the end of the grease gun, and one of it's uses is to inject grease into bearings with rubber seals.
You don't puncture the seal, but work the needle thru the sides.
$7, and of course they are located next to the grease guns.
Whilst doing some work on the timing belt, I took the opportunity to grease all the A/C bearings (Including the compressor bearing), serpentine belt tensioner and most importantly the fan bearing ( the one pressed into the front cover of a 300 Tdi - also the one really hard to replace)
It is easy to use and does not damage the seal - provided you are gentle about it of course.
A note for other 300TDi owners: Give thought to greasing the fan bearing on a regular basis once you get around the 250 - 300K mark. Whilst my bearing was OK, it was obvious that the bearing was empty of any sort of grease. Had I left it for another 50K, I imagine it would have seized up.
