sound like what i am experiencing,4wd light is off but cad not fully disengaged.wheels still grab and over 30 mph i get a shudder and noise from front end.put it back into 4wd and everything works the way it should.
hurry up and get here posi-lok,cant wait to get it installed.

 

okay,so i couldn't wait for part to arrive.i removed the old cad 2 bolts were tight like hell,put the heat to em though and they came out no problem.really sucked laying in the snow but to bad EH,welcome to canada.

 

Bent axle ... damaged u-joint ... bent shift fork? That scraping sound you're hearing ... does it sound like a brake pad dragging?

 

that happend to me, it would not fully disengage...it was a really cold winter here tho so it was kinda froze, i had ice and a lot of crap all over my hub and what not too. I can't fit my truck in the garage so it sucked that I couldn't keep it warmed up. But we hada warm week and it got into the 50s, so i cleaned it all out, replaced my hub and now its fine. I hope all the stuff works out for you man, let me know.

 

i hope its nothing major, it doesnt do anyhting wierd in 2wd but in 4wd it is goofey when turning and we can rule out brakes cause i know they are in perfect working order

 

also what does this hub thingy look like to replace?

 

LMAO, just noticed... the "shocker" in your signature image.

update #1. someday when you really need 4wd to get unstuck and you pull on the cable and it won't move... the too small of a cable tie broke and the posilok cable has fallen onto the exhaust manifold and melted the plastic into the spiral wrap. damn. so you get to remove the whole thing, strip the plastic from the melted area, and sort of work it back and forth until it frees up. then put it all back together. tip- tie the damn thing away from the manifold.

 

update #2. my mysterious and sluggish cad engagement is solved. while replacing axle u-joints and seals, i also replaced the 2 bushings at the cad. the larger one is at the inner housing. i replaced the bushing with the bearing. the smaller bushing is where the 2 halves meet. both of mine had a little wear and play.

the bigger problem was burrs on the splines of the inner axle and the collar. this created a very tight fit to engage, and explained why it was so hard to get it lined up right. i filed the burrs off with a hand file. now it engages smooth and easy.

the vacuum cad still sucks. get a posilok and you'll love 2wd low.

 

Hey do you still have the images stored somewhere, I can't see them on the thread but I'm considering doing this mod and would like to see how you did it.
