Before you replace your carriers...
It should be known that normally theres a decent amount of movement in the carriers to begin with.
I went to replace them last night and the new ones felt just like the old ones. The old bearings were still packed with grease, no play and spun freely with no catching, rubber was in great shape w/ no dryrot at all, so i just replaced the u-joints.
So confirm that yours do in fact need replaced!
BTW, if anybody wants a set of carriers (MB505495), I'll sell both for $60, along with a u-joint (you only NEED to replace one).
I also have an extra transfer case yoke. $20.00
