i have posted once or twice about a suspicious rattle and/or vibration in my front end. (95 f150 4x4 351 5.8 ifs)... with all the responces it seems to be narrowed down to a susspension issue. i took a look at my system and nothing seemed blatently obvious as to a problem. so i went for a drive and tried to note as much info as possable... with regard to questions from earlier posts.

only vibrates around 115-125kmh
tires recently balanced (problem was there before and still there after)
rattle or vibration is worse going downhill and almost eliminated going uphill
seems as though it is coming from front pass
my vss is still hooped... and my O/D light does not flash

in the case that it is not susspensin related it also seems as though it is throttle related. whether that is do to accel and decel i dont know, but i was also concidering something drivetrain or axle related...

cv
ujoint
driveshaft

all guesses, driveway mechaninc 101...

any and all help is highly appriciated, vibrations make me not drive too fast so that keeps the cops off me but also, everyone hates the guy doing less then the speed limit on the road...

 

Do you have a carrier bearing in the middle of the driveshaft? Also check to make sure that the front axles are not locked.

 

i could lie and say i knew what a carrier bearing was but i think you would know i was lying. and yes the first thing i checked was that my axles arnt locked... im an apprentice and that kinda gas consumpton is beyond my paycheck
