the mehle droplinks seem well made. i bought a set 6mths ago. they are very well packed with grease under the rubber boots. i would not attempt to put more grease in them again as i tried. maybe the sringe idea will work but once the rubber boots have been disturbed, once on full lock they will keep slipping off.they have very weak boot retainer springs. an mot or advisory/ fail actually for allowing the ingress of dirt. to be fair to DMGRS his offerings are pretty good and do have excellent boot cover springs. i have put some new ones on from mat again now and will try to secure the boots on the mehle ones again. if you have already bought the mehle ones , just leave them alone and fit them as they are.
