driveshaft issue after lift

not 100% sure if this is the right spot to post this, never posted in this section. I have a 96 f250 ext cab long bed PSD. I swapped in a d60 solid axle and did a 4in lift at the same time. ended up with a little over 7in of lift. after i got everything in and test drove it i had a vibration. checked everything was tight so i dropped the carrier bearing 2in thinking it would help, it did help as long as i dont race someone or lay into it then i get a bad vibration which im sure is probly some axle wrap because in order to get the back close to the front height i added a 3in block under the stock 2in block and added a rear add a leaf.
what should i do about the add a leaf and blocks? can i run like a 6in lift leaf and the stock block? I was doing some research and found that you are sopposed to have a positive angle on the drive shaft joint after the carrier bearing and i have a negative. would a one piece drive fix this problem? thanks

You shouldn't need a one piece. I still have a 2 piece and ZERO vibration with 12+ inches of lift. You really want the driveline as straight as possible.

Take a picture of yours..

well once again for some reason it wont let me load pics on here. but i took my angle finder and the front section is at 12 to 13 degrees, and the rear is about 3 to 4 degrees. I saw somewhere that they should be with in i think 3 or 4 degrees of each other dont know how true that is. I am in the process of making ladder bars for the truck but i would really like to know more about the angles they should be at.
thanks

Like I said, you want it as straight as you can. Since you mentioned all the blocks is your pinion angled up slightly?

thanks

One Up Offroad Drive Line Drop

Get one of these. Fully adjustable for pretty much all lifts.

They are kind of spendy at 175 ish.
