new hub bolt length

'75 Cj5...

I had original lock-o-matic front manual hubs on. I ruined one and ordered new Warn hubs from Car Quest. The original 6 bolts that held the lock-o-matics in are 3inch bolts, the hub itself it self is about 2 1/4inches long, leaving about 3/4 inch of thread going into the hole.
The new Warn hubs are only 1/5 inch long (where the bolt goes through), so my factory bolts are way to long.
Has anyone else run into this?

Do I need to get 1 1/4 inch bolts with the same thread?

 

Yup........or 1 1/2" Or better yet, use studs with nuts. They never get loose. The studs I used were coarse thread on one end and fine thread on the other. About 1" of thread on each end. I used Locktite on the threads going into the hub and used a nut and lock washer to hold the Locking hub to the wheel hub.

 

:iagree: The holes on my hubs are backbored about 1/2 inch, I bought bolts with a shoulder/body length that is long enough to go through the locking hub and into the backbore then cut off the threads just short of bottoming out, In my case due to bolt shoulder/body length and available length selections I had to run a die up the bolt a few threads so they would tighten up properly.

I chose this option because the locking hubs I have would require a little over two and one half inches of stud, I thought it would be better to have the larger body of the bolt in the softer aluminum hub than the smaller threaded portion of a long stud ( studs with a long shoulder were not readily available or I would have give them some consideration ) The hubs did show some movement wear from the short shoulder bolts the PO had in them and they had been overtightened a number of times in an attempt to stop the movement to a point that the locking hub castings were distorted. I got lucky and ran across some that were like new and was able to obtain them.

If you do not choose to run studs a custom fit long shoulder/body bolt is a workable option, I have had no problems with them working loose.

 

Hey, do you want to part with one warking lock o matic that you have left over? I wouldnt mind having a spare.

Where in upstate NY are you? I go up that way quite often.

 

You have a PM.

 

I got the right size bolt, and they fit fine, but they dont work.. I put the front left one on. I turned it to lock,, jeep on jack stands, put the transfercase in 4wd and spun the wheel. The drive shaft doesn't turn :?. Do I need both on for them to work? what is going on here:? I attached some pics of the new hubs, it almost seems like I am missing something....

What is that little black bar on the left for??

 

yes, the both need to be locked for it to work, otherwise the differential sends all the power to the one that easiest to drive, which would be the axleshaft with no wheel to turn, the one you cant see. If you watch the ujoint that attaches to the opposite wheel it should be turning in the opposite direction that you spin your tire.


thats a different upstate NY than I'm used to. I head up to Saratoga/Albany region quite often. I was out in Elmira for christmas though, and My brother goes to school in Rochester.
