Can anyone please give me some info on "Warn Manual Hubs". I would like to change the factory vacuum hubs with Warn Manual hubs. What are the advantages and disadvantages in switching over? Where can I buy them? How much are they? Do I need special tools? Any information is greatly appreciated.

I got mine from Advance Auto Parts. They had to order them but they came in like 2 days. $104

Just follow directions that come with them.
Un-bolt old ones, when bolting on new ones only use the lock-washer, leave flat washer off.
Then, disconnect the plug from the vacumn solenoid.

Only draw back is you have to get out and lock them in.

However, at least when you lock them in they are locked. On vac ones, if solenoid went bad, no 4x4. If a vac line broke or leaked, no 4x4. The manual are to me more reliable.
(unless you forget to lock them in and rolled backwards down into a tree. not me , friend in a nissan p/u)

Anyways, they will work for you.

If forsee that you will need them you can lock them before ( say 10 KM prior - what I do ) (eventhow some say that you can make more distance with them locked and with 2wd) with the dissadv. of increased drag and gas consumption.

I had my mother-in-law in the sporty when I discovered my vaccuum hubs failed, need I say more?

Got mine at Carquest for about the same $105ish, haven't missed a shift into 4-wheel since. 6 10mm bolts per side.
