Help with rear suspension

Major vibes after 3" block. Looking at axle shims. What degree d I need for 3" blocks?

 

I read on here the cb drop is more for high speed vibes. So I should go ahead and do the cb drop first? Then try shims or the opposite?
Also, the blocks have a slope in them. Do they slope downward toward the front or toward the back of the truck?

 

Generally a slope would go up towards rear of vehicle, but 3" block.....i personally wouldn't run that on my tacoma. Crappy ride, axle wrap, etc, etc

 

So am I better off doing toytec 3" aal?

 

see this post for source of problem; though with a 3"block you likely hav axle wrap problems as well changing the driveline angle during acceleration.

Ok read up on the thread. Thanks for that after all the searching I didn't see that one. I've got the cb kit in and shims on the way. My leaf looks like shit! Guess this is axle wrap? Looks like an "~" instead of a "u".. So should I go with the add a leaf now or should I just go down and buy some clamps (I've seen this as an easy fix). It will be another week before I can get the aal too. Is it gonna hurt that much to drive around for a week like this?

Thanks again guys for all your help

My leaf

 

Ya, that's caused from axle wrap. I wouldn't be surprised if you break a main leaf. Be easy on the throttle if you drive any more like that. Do it right and order a set of replacement 3" lift springs from deaver or alcan. Shims won't fix bent springs.
