[silvertaco4x4]

thanks for the suggestion, i had actually been considering that. but, i must have jinxed myself with that last post because this morning, the truck was knocking despite warmer weather. disheartening to say the least...not sure if its the same knock or different one now. this morning it almost sounded lighter and lower down on passenger side. it only ever happens if i actually drive off before the truck warms up, and doesnt really last long enough to do a decent job of trying to locate it.
