I call it a 98-1/2 because it look like a 1999 (4 door), and has a manufacturer date of 8/98
2 problems.
1.) Will not engage auto locking hubs all the time (VERY Intermittent ) The Sticker says there's Pulse Vacuum Hublocks, the Chilton manual says there's a "vacuum disconnect axle lock ass'y" But I cant seem to find it. An internet search found an interesting answer

A vacuum leak?? This would answer why it sometimes works. But if I can't find the vacuum lines or axle lock ass'y, I'm lost. Anyone else heard of the vacuum leak problem? Should I go through the hassle or should I just replace them with Warn Manual Hubs?2.) Antilock kicks in during deceleration at 5mph, even though the tires aren't locking, I can assume it's an antilock sensor because the vehicle pulls slifghtly to the right when my brake is applied and the antilock kicks in. Any suggestions other than buy a new truck?? :-)
