greetings all. my dilemma is this. 1999 toy tacoma 4wd with 70200 miles. purchased the 3.5 basic fabtech kit and had it installed by 4wheelparts. i have developed a bumping noise at slow speeds and while making turns. noise is made when truck rolling on own weight, but not when off the groung and free wheeling.

7/8/04 pulled off manual hub and to might suprise, a 12mm bolt was floating inside the manual hub assembly. i have 4wheel parts to thank for that as well as a list of other problems since they touched my vehicle.
chiltons manual states that a retaining bolt on the end of the front cv axle is supposed to be there, but i do not have this bolt on either side. am i supposed to? sorry for the noob question. i am at my last thread of patience with what is wrong with my truck. PLEASE HELP ANYONE!!!!!
