Ok, I'm confused...I was browsing the JC whipme catalog and ran across these manual locking hubs:

http://www.jcwhitney.com/webapp/wcs...&Ntx=mode+matchallany&langId=-1&storeId=10101

I was under the impression that with the 77 Jimmy/blazers that have the full time tcase (NP203) that in order to go "Part time", you had to install a MM kit in the tcase - AND that you could NOT just install manual locking hubs on the front axle and have the SAME part-time capability...I thought if you put manual locking hubs on, the tcase would try to send more power to the front wheels and thereby causing the vehicle to become immobile (Unless you had the Tcase in any LOCKED position)....

Am I missing something here?

I think the "manual coupling gears" part is the blocks that go into the transfercase. Those hube for half-ton are ussually cheaper than that.

I think that is the whole kit.

Hmmm, OK I think I "may" have it now...I think I read the part where you don't have to remove the tcase and got all excited about this...lol

So, If I understand this, "basically" - you have to remove the rear of the tcase and install the "coupling blocks" then install the locking hubs - correct?

Lastly, is something like this even worth the time and trouble? This isn't my daily driver and its only used for my hunting vehicle (when its running) .... :roll:

Your thoughts on this? Anyone? ('cept Payge!!) :mrgreen:

I think it might be worth it. It will save wear and tear on the front end and the front driveline.

It is real easy to do. We did my buddies in his front lawn.

Having the hub setup could be helpful if you do have problems with your front end. It would be easier to isolate it out.

Just keep in mind that you need to throw it in 4X4 real regularly for a bit and drive a ways to splash oil up into the works, or else you have way more problems than you do now. When these type of kits first came out, one of my instructors told me that he made gobs of money hand over fist by first installing the kits, then replacing the transfercases and hubs and gears when the new owner didn't read the fine print and throw it in 4X4 often enough to keep it all lubed up good.... :deal:

If this is the case (no pun intended), then I wouldnt bother with it. If it was driven on the street often then it might be worth it to save a little gas and prevent wear and tear.
