How to check 4wd vacuum canister ?
I am also stuck with 6" of snow and no 4wd. We just bought this and have read several pages of these posts. While I would like to replace the vacuum system hubs with the manual, I really don't have 150.00 to spend right now, so i was hoping for a cheap repair till later. I have replaced all of the vacuum lines from the wheels to the vacuum canister and that didn't help. I know the transfer case is working because i can see the axle turning but not the wheels. So to try and fix the original system where do i go from here? How can you tell if the canister is working itself? And if its not how do you tell if its bad or if the celenoid that I read about sending the signal is bad ( thats if I'm understanding how this works to begin with lol). and if those are working does that mean the hubs themselves are bad? Would taking them apart and cleaning them help any? Also, i read one post that said when these go bad that dirt, etc. gets in and cause the wheel bearings to go bad. When I got it inspected the other day the mechanic said the one wheel gearing ( front DS) was borderline passable and should be replaced. Would that be an indication that the hubs vacuum was bad automatically or are there other factors? Thanks in advance for your help. If Momma doesn't get out of the driveway and to the mall Santa might not make it this Year. Happy Holidays !
