EASY! I recently(today) replaced my hubs after buying my warn premiums and worrying about what i could f* up with this job as there were no guides with photos so i(kinda a noob, had rebuilt one engine and worked some on a dirt track modified car) wouldnt know what to look for. i had read the posts on here but still had some questions as i started. heres how easy it really was! i had never worked on axles before and thus the doubts i had. TO BE USED IN CONJUNCTION WITH THE HUB MANUFACTURER'S INSTRUCTIONS( OF COURSE!) I guess. 1991 k5 sliverado with everything stock(10bolts then) what's in the package: http://www.bowlingballexchange.com//upload_files/broncograveyardwarnpic.jpg The auto hub cover: http://www.bowlingballexchange.com//upload_files/P3260011.JPG 1. Jack truck up by the axles tube and put a stand under the tube also just in case. 2. remove hubcap cover: http://www.bowlingballexchange.com//upload_files/P3260012.JPG 3. using a T25 torx socket remove the cap screws. The cap might pop off as the spring inside might force it off(not really that strong of a spring though), it might not pop off http://www.bowlingballexchange.com//upload_files/P3260013.JPG 4. Spin the wheel till you get this piece up http://www.bowlingballexchange.com//upload_files/P3260016.JPG 5. using a pair of snap ring pliers pull the clip out from the middle: http://www.bowlingballexchange.com//upload_files/P3260018.JPG 6. Where the clip used to be compress the two pins to be able to pull out hub: http://www.bowlingballexchange.com//upload_files/P3260019.JPG 7. Pull out the hub: http://www.bowlingballexchange.com//upload_files/P3260020.JPG you can insert a screw into the hub if it doesnt come out easy, mine came out pretty easily. 8. deep in there by the axle shaft is a snap ring http://www.bowlingballexchange.com//upload_files/P3260021.JPG ...look for the two holes and use the snap ring pliers to pull off the snap ring: http://www.bowlingballexchange.com//upload_files/P3260022.JPG 9. Pull out the washer that was behind the snap ring: http://www.bowlingballexchange.com//upload_files/P3260023.JPG 10. install warn hub(you may need to jiggle it to go in all the way). you may need to pll out the axle shaft a touch out of the carrier from underneath the truck: http://www.bowlingballexchange.com//upload_files/P3260025.JPG . 11. if you have the outside groove on the axles shaft out far enough that you can get the snap ring on put it on using the snap ring pliers: http://www.bowlingballexchange.com//upload_files/P3260024.JPG 12. install locking ring on outside of hub(it just snaps in): http://www.bowlingballexchange.com//upload_files/P3260026.JPG 13. put cap on and use an allen wrench to screw in the cap screws(dont overtorque the screws!!!!): http://www.bowlingballexchange.com//upload_files/P3260027.JPG (i had put the hub cap cover on already sorry) 14. having the hub n the locked position spin the wheel to see if the driveshaft turns, if it turns set the lock to free and jiggle the wheel(POP!) and spin the tire to see if the lock disengages. if the drive shaft doesnt turn youre all good!. the crap that got pulled out and not put back in: http://www.bowlingballexchange.com//upload_files/P3260028.JPG DONE.. http://www.bowlingballexchange.com//upload_files/P3260029.JPG took only about 20 min each side does that look correct?
