vibration.....

[5.0Flareside]

well i have had this vibration for a while now and ive done several things to hopefully fix it which none have. this includes rotating and balancing my tires brakes and rotors fronts and checking the u-joints..... and the vibration is still there. and its only when im accelerating. when im WOT its worse than when slowly accelerating... and it goes away once i get to a speed and cruise and i got to thinking....


motor mounts or tranny mount.. which would explain why its worse when WOT. if im wot the motor is gonna be torquing more and so will the tranny. so whats the easiest way to check for loose or broken mounts... are there any dead give aways....

just let the woman drive it, and never worry about it again...

 

[5.0Flareside]

haha nope. even though i would love to swap motors with her.... that ***** dusts my *** when im running wide open and she is 3/4 throttle.

 

[nobodyspecial]

I was just saying, she may not complain about the vibration.....

 

[5.0Flareside]

hahaaha... no but she'd complain bout how slow my truck is compared to hers.

 

[nobodyspecial]

What has been done to the other 351?

 

[5.0Flareside]

not real sure. we've only had it since october. and its still speed density so its not a real serious build. but its supposedly got 3.55 ls but i think its more like 4.56 ls. havent checked yet... but mine also has 230k on the motor.

that motor would scream with 4.56's...

Did the problem exist before you swapped rear-ends?

The only real way to check em is to see if theyre seperated or cracked. Id also check for missin or loose bolts.

I have this same problem. it usually happens around 45 mph and up. when im on the gas or just cruising
