Do I need shims? if not what do i need?
hello everybody i recently installed 5.5" trail gear shackles on my 93 toyota pickup. as soon as i try to pull out of my shop. i start to steer and realize that my rear end is binding up and acting like i have a locker in the rear (tire chirp). i then put it in 2 wheel drive. and the problem is solved. why would this only do it in 4 wheel drive. it makes it so i cant steer at all in 4wd. please help. do i need to shim under my leaf pack or what?

Front tires have to move farther than the rear to complete the turn. The front and rear diffs are connected via the transfer case. It is not a limited slip transfer case.
This is why you are never supposed to use 4wd (without unlocking your front hubs if avail) on hard surfaces. The tires need to slip.
Look at your pinion angle, is it bad? I doubt it is. Longer shackles rotate the axle to give you a better pinion angle.

yea i realize that whole concept. I know that your not supposed to use 4 wheel drive on hard surfaces, but i live in alaska and spend most the year in 4 wheel drive and on plenty occasions use 4wd on turns on hard surfaces (parking lots, dry patches of road .etc.) and ive never had an issue other than the normal tire bite on sharp turns... but now with the shackles i cant turn at all without horrible binding and lunging and tire burnout marks from the REAR tires of my truck, even if the wheel is only turned the slightist amount the truck ..doesnt want to move .someone please help! thanks for all ur input

It was likely having problems all along. The geometry change just made it more obvious.
4wd and hard pavement don't mix. It puts a lot of strain on the drive line.

try going back to stock shackles?? i know that sucks , also with the shackles did you recently add tires?? or anything els, doesent really make sense with just the addition of shackles, all you did is change your pinion angle..

also if you put five inch shackles on yo mostlikely went with larger tires which would give more traction inturn cause thus problemto be more noticed than before. rather than just sliding along as usual now the truck tries to stick to the ground and binds up.
