im getting a ton of vibrations when i let off the throttle, and sometimes when accelerating some.

i just installed my rb 2" bl, with new poly bushings, and new front rotors and pads.

the vibes were present before these two things but not as bad.

they started after my suspension lift, OME and tundra up front, alcan pack and bilsteins in the rear.

it is really violent sometimes, and i also hear a slow rotating thudding sound when im slowing down, which i believe to be my CV's. i did do a 1" diff drop with the susp lift though.

anyone have any ideas and or suggestions on what to check
?

thanks.

 

You can remove front drive line from the transfer case to the front axle and if it still vibrates it may be the rear drive line or differential or axles.

 

like take the front driveshaft out?

 

dunno the source of the vibrations, but the poly bushings are probably what amplified them.

 

possibly the u joints? from the changed angfle of both front and rear?
they would be semi-binding twice per revolution and it would cause it to jerk...
