When you squirt grease into new front end components, do you fill em all the way up?

If by 'all the way' you mean the grease coming out all over - No. graemlins/clonk.gif
New components should have nice tight fitting dust (grease) boots and zerks. They should be filled with several pumps of grease until the boot just starts to 'inflate' a little - maybe halfway full. To much grease will not do any good and could cause one of the new boots to blow off (come unseated not all the way off). I've seen this happen several times.

The new parts usually have a small amount of assembly lube left on them so they do need some more - just not filled all the way. If you have any doubts about them you can always check in a month or so and add a little more if needed.

thanks man

With tie rod ends the grease goes right past the boot easily. Many older ball joint boots had a small vent hole to allow excess grease to vent. On those, it's a good thing to grease it until you see clean grease come out. This flushes dirt, water, old grease from the joint.
The newer ball joints and many replacement joints no longer have the vent hole but my Camaro boots are not held down by anything but the tension of the rubber and would easily unseat a bit to vent the old grease.

I usually pump till I see a bit of old grease coming out, then stop. The tie rod ends I grease till I see clean grease come out.

I don't ovedo the uppers as the boot may be damaged.

I'd figure yes for the new components. Just keep and eye on the rubber boot swelling. Some real tight ones can ballon and it's no good to pop a boot or when they do allow the grease to release a bit it can be a major mess since the stuff is under preasure from the balloning. Yah I just got a chuckle out of remembering some major runaway grease ejection. Have a few rags handy or on the hand holding the grease gun to the zerk.
