I'm new here and just did the u joints on a friends 07 and they are squeaking. The new joints came with zerks to graese I did not grease figured the graese that they came with would be fine. Am I wrong on this? Oh sorry iF I hi Jacked the threat

 

the grease they came with is just for shipping and keep from rusting, should always put a pump or so of grease in there when you do them.

squeaking is bad...means its running dry..
