need help with Axel Blocks

Just recently got a 2000 tacoma . i know when i installed my blocks on my Silverado they had to go one way. The guy that did the intall on the yota has one way and the other different. My question is which side faces the rear? The fatter part of the skinner part?

 

Fatter part of the block should be at the back, it is tapered to allow for correcting the driveline angle.

 

thats what i thought what a retard he is lol how could you not notice that? i was trying to diagnose this horrific clunk when leaving from light when letting off the break nad decided to take a look at the blocks to make sure there were right and they were wrong... thanks for your help.

 

i was thinking of doin the u bolt trick in front of the axel i heard that helps? Im goign to start by flipping the one block then grease the slip yoke see where that gets me if not i will be trying this u-bolt trick heard it helps greatly. i would like to get rid of this stupid 2 piece driveshaft what a stupid design.

 

Just another thought, if you still have a clunk after you correct the blocks, you may also have a bad U-joint, try to grab the driveshaft at each U-joint and yank it around to see if there is any play, there shouldn't be.

 

ya im going to replace them to pretty much goign to replace from the tranny mount back get everything fresh
