Exclamation PLEASE HELP.. Leafs, blocks, driveshaft?

Ok, so i have a 98 frontier. It had been lowered with 3" blocks when i got it. Was not low enough for me, so i pulled the middle leaf and had the 3" blocks in. All was well for a couple days, was really happy with how it sat. After a couple days, the truck started making a really loud "clunking or popping" noise. Its the worst when i take off kinda fast or on hills. I added another leaf and just put 4" blocks back in, didn't fix the problem.. Any ideas on what the hell is going on? I've now been told replace the bearings on the leaf hangers, shorten the drive shaft, replace the carrier bearing... Ive searched the forum and haven't really found anything.. Should have left it alone

Look at the carrier bearing. See if the rubber is intact. See if the driveshaft flange is hitting the carrier bearing bracket. Are the 4" blocks angled?

Would angle blocks actually make much difference? Should i try that before having the drive shaft cut?

Check carrier bearing, check u-joints, and ya need angled blocks for anything over 2"s for the blocks. Ya also might need to put spacers in to raise the carrier bearing for the driveline angle isn't putting u-joints in a bind.

Thanks guys, what exactly ya mean by spacers? How would i go about doing that. Id like to be able to do most of the work myself and save on taking it somewhere because apparently I've spent a lot of more i didn't need to on different blocks and such and buying new leafs.
