Without going into a long thread, just going to try and give you what i think could be the problem and see what is thoyght by the group. Here is what i know. '95 land crusier. Just rebuilt the knuckles and got the preload finally right (thanks kernal). About a week ago igreased the front and rear Ujoints and slip yoke. Since greasing the driveshafts i have started getting a noise that sounds like its coming from the right front wheel. Ill try and describe the noise the best i can. It has happened at speeds over 60mph and usually when i let off the accelarater. The noise sounds like something trying to turn that isnt being able too. Like trying to push a heavy desk on a wood floor making the desk grab and then lungh forward sometimes once sometimes 2or 3 times in a row and yesterday drawn out . This probably doesnt make any sense and ill probably be taking it to a toyota dealer but am hoping to resolve this issue without the dealer and with the mud community. Sorry for the terrible description and thank you for any and all help
