so i replaced the 4 ball joints on the truck not too long ago, but since then, when i turn the steering wheel to full lock while in reverse, i feel the ball joints popping. there's no quick fix for that aside from replacing them again, is there? a side note which may help diagnosis: i didn't have my grease gun around when i finished installing the uppers, and drove less than a mile down the hill to the local oil can henry's and asked that they lube those for me. the guy then sprayed grease all over the top of the fitting and didn't get any into it. i drove it for a week like this before i figured it out. aside from this problem what could I have done wrong? how likely is it that this ruined the new joints? also, it only pops when in reverse at full lock, never in forward direction gears. in 4wd, it still only pops in reverse, but much more substantially - you touch the wheel and it starts popping. thanks for the help.
