can i grease bearings without lifting?

Just leave it alone, if you pump too much grease in through the EZ Lube axles you will blow out the seals and create a problem where there wasn't one. I have thousands of miles on my TT since I repacked bearings 3 years ago. If the seals aren't leaking and there is quality grease in there (I use Mobil 1 synthetic bearing grease) then you won't have a problem. I plan to repack the bearings this summer....if I get around to it.

Re-packing your wheel bearings every season is going the way of the 3000 mi oil change...just not needed.
