Mine are really tight to turn, I pulled off the driver side one and pulled it apart totally. I cleadned it and re greased it. The problem in in the turning mech. thare is a rubber seal/boot that covers it on the inside. Is this part replacable? I want to remove it to clean and lubricate the mechenism. I have a buddy that used to have the same problem and he did the same thing i just did and it did'nt help him either.

I noticed on my 2007 SD it is super easy to engage. what changed? is it interchangable to my 99?

 

What do the axle bearings look like?

 

thay have no play. somooth and not hot.

did not pull apart
