Vibration from new suspension

So I just finished installing my boss suspension kit from toytec. I went with new ome leafs and ome shackles. So my problem is driving from 5-20ish mph there is a very noticable vibration(no noise really). It's not like a loop from the engine it's a solid vibration. I installed the bpv bracket. I didn't install the diff drop yet could that be the problem??

 

also i installed my suspension in 2 phases. first the coil overs went in and i tried the leafs and couldn't get all the seized bolts out and gave up. i didn't get the vibration after the coil overs.. a week later got new bolts + shackles and installed the leafs. the vibration is mostly noticeable from 15-20 mph but is still there from 5-15 mph. its there wether my foot is on brake or gas.

 

Carrier bearing I would guess.....plenty of into on the drive line angle

 

Does it go away in 4wd?

 

good question.. not sure yet i haven't tried. in 45 mins ill have that answer since I will be leaving work any moment.

hmmm maybe just put some spacers on the carrier bearing? but yea that definitely would make sense since it only started happening after i put the rear suspension in.

 

I am guessing the new leafs changed your drive line angle .
Time to buy an angle finder and shim away

 

Thanks that sounds right. Anybody have any links on figuring out your driveline angle..? Can u get axle shims at auto stores?

 

Lotta great reading here on how to cancel those driveline angles

Some rule of thumb I was told once is 1 degree for each inch of lift. I went with 3 degree shims on my 3" rear lift and absolutely no vibes.

 

This is like the 3rd time ordering from toytec for this lift. Gettin screwed on all these shipping charges haha.. But yea I'm ordering those ones. I probably shouldn't drive it eh?
