| Transfer Case
My transfer case will not lock. It appears to have a vacuum leak at the differential. 1. Can I replace the vacuum diaphragm while still in the truck? I think that I have enough clearance to pull the cover without dropping the entire unit. 2. What parts should I order in combination with the diaphragm? See attached image...

See if that comes as a rebuild kit with the spring etc kind of like the kits for the axle lock solenoids. You may also need a gasket for the cover. |

I did this a couple of times because the diaphragm had torn. All I needed was a new one, part no 23. You can remove the housing, no 38, without removing the transfer case. The most fiddly aspect of the job is making surs the new diaphragm sits properly against the transfer case body. There is a recess in which the diphragm ring needs to rest. You can use a bit of vaseline to hold it in place while you tighten up the bolts. |

Could this be the fault in mine, dash display says TC in neutral, it will not shift, but stays in high and will still drive? |

Can't moon problem indicating that the TC shift motor or gear is getting ready for service.
Do a Search here. Not here is a way to get it working properly again on a temporary basis. |

| RE: Transfer Case
I did this today and it was a bit of a pig removing the housing from the diaphragm as the bottom of the housing gets caught behind the flange of the fwd prop shaft, I finally got it off but couldn't get it back together easily enough to be sure I wouldn't cut the new diaphragm.
I ended up removing the front prop shaft which helped access but it still did t easily clear the the front flange for the prop shaft on the transfer box. I ended up filing the bottom of the housing to clear the flange and it works a treat, if I need to do the job again it will be far easier I only had to clearance the housing by around 1/4 inch. |
