I have 92 f150 2wd 4.9 litre just the other day im driving home from work and i hear this pop under the truck and now theres a rattle in the front of the truck seems like right under my feet.not sure what it could be everything seems to be intact,just not sure what could have happened.has anyone experinced this before?

If your radius arm looks like the 1st pic, then the bushing has broken apart and that could have been the pop you heard.
