Thread: most common problem with 4x4 vacuum acuator system?

One off the reasons this is such a problem is that the bolts that keep the whole unit on the front axle are twisted off and once i break the seal and take it off will i ever get it to stop leaking ,and its a big job to drill out those broken small bolts. i don`t know how the cable works but i assume that you have to dissassemble the complete vacuum system from the axle.

CAD cable manufacturer site. Another option would be to go with the '02 solid right axle shaft and put a plate over the CAD opening. That's what the pullers do. There is another option on that page that I haven't seen before. It's a new cover and a bolt assembly (Perm-Lok) that locks the axles together permanently. If my truck goes off-road (other than pulling the snowmobile trailer to a lake race site), I'm in...

My stock set up works ok, only had a 4x4 light issue with a broken wire. CAD actuators are on ebay for $65 if I remember corectly.

Purchase the cable system. If the bolts are stripped or broken, addrss it. Drilling and tapping is not that hard. Just do it. You will be glad you did. (This was a motivational speach)

Water in CAD?? see posts RE: replumbing and moving vent up to firewall. I know it sounds like witchcraft but no system intended to siphon relief air in should be positioned less than 2 feet off the roadway!! Knock wood Mine is working great for quite a while—my vent is at the firewall/hood gasket… if I'm taking water there I have BIGGER problems!!
