my jeep had a little vibration going down the road.

started at 30 mph, and was done by 40-45 mph


when i would set the cruise at 55, i would hear or feel nothing, until i tapped the brakes and then it would vibrate down to about 30 again


well, i decided to have a look at the u joints in the drive shaft....

They were tight, not much play in them at all, so i decided to have a driveline guy look at it (maybe im missing something?)

Turns out the u joints are fine, but b/c my jeep has a 2-3 inch lift, it pulled the driveshaft further down the shaft coming out of the torque converter

it was on by only a 1/4 inch

needless to say they are making it longer...so im hoping that takes care of the vibration

He (the expert drive line guy) said that it would b/c its not on far enough

just a little heads up for everyone with 2-3 inch lifts...check to make sure your drive shaft is long enough (keep it clean guys and girls )

But seriously...if you have a slight vibration and you have a lift..check it

 

Ah you've discovered why people buy SYEs

 

didnt think i needed one for a 2-3 inch lift

anyway, extending this was about 100 dollars, sye is a little more expensive

anyway..that should solve the issue regardless
