If it does go away you may have the front diff vibe....Check out this thread..

 

Still there it seems, I am not surprised though, I only have 7600 miles on her. I would be really surprised if it was my front diff.

 

I just thought.. Maybe????it could be Its not really a front diff thing its the needle bearing giving the cv to much slop in there..... the ECGS bushing eliminates the slop.

 

Do you have the ECGS bushing and if so did it work for you?

 

yes and yes

 

I still have a slight take off vibe but the bushing eliiminated the rumble strip feeling in the front and gas pedal..30 -40 mph vibe went away in 4 wheel though before bushing install, so if vibe doesnt go away in 4 wheel Im not sure if the needle bearing is your problem..

 

I guess I am lucky in that sense. I checked the torque on everything and removed my overloads. It completely got rid of all the shuddering that I experienced on accelerate/decelerate and at 20-30 mph. I don't have any "rumble/shudder" just a sort of whirring/high speed vibration at 40-45. I looked closely at my front end and rotated with a stethoscope. I didn't feel any slop in my drive axle or hear any grinding to indicate a bad bearing. I am crossing my fingers that is the case. I did however notice that my driveline is slightly at an angle between the 1st and second drive shafts. I should be able to correct that alignment with a 3 degree shim or drop/rotate the carrier bearing. The thing that is really kind of throwing me for a loop is that after driving for about 30 miles it seems to have diminished significantly. Thanks for all your help. The link helped to (hopefully) eliminate the fwd diff (bearing) as the culprit.

 

Glad I could give you another insight.. Hopefully you will figure it out.. Nice looking truck by the way Good Luck....

 

Thanks Brother, You too...

 

You mean sister

 

yes that is what I meant......

 

Ordered steel 3 degree shims for the spring pack today, Crossing my fingers. Before ordering I did check with an angle indicator to determine if my pinion was that far off, surprising to me it is about 3-4 degrees off. Just looking at it I didn't anticipate that it was that far off. Well if it resolves the vibe or not I do feel better aligning the drive shaft to pinion angle.

 

I put 3 degree shims on with my dakars and everything is smooth, I think your on the right track.

(No CB drop)

 

That is good to hear, did you have vibes before the shims?

 

Based on research I did around Tacoma World (Shim vs CB drop) I decided to put them in with the leafs right away and opted not to do the drop; so no experience with out them. But everything seems good so far.

 

Sounds hopeful thank you

 

Tires are here

 

Now waiting on these to come on the barge,,,,,,

 

Love those how much were those? Think your gonna have any rubbing issues at all?
