locking hubs?

[yetiwarrior82]

ok. i have a 79 CJ7 and it has QuadraTrac . now i've never delt with QuadraTrac so idk how well it works so i was wondering is it possible to put in locking hubs instead of having the QuadraTrac ? if so how would one go about doing that

Yes, you can add locking hubs..

HOWEVER, you need to add those in addition to a 2x4 Transfer Case conversion kit!!! such as Milemarker

DO NOT just add the locking hubs. Doing so will tear up the TC.

It is meant to be fulltime 4wd, and by unlocking the front end, it really messes up the TC when there isnt any resistance when there is torque applied to the front output...

I got my kit in 1988 and paid $365 shipped...They arent as cheap nowdays. I recently saw a used kit for about $275 on ebay. Once in a while they come up for sale. That would have been a smokin deal.

Either leave it as is, or get the full 2x4 kit for it.

Brian is spot on. If you dont convert the Transfer Case you'll burn it up. Its not a bad idea if your Transfer Case is a bit sloppy to begin with. Theres a 16%Overdrive kit as well

Did some looking to find that old post.
It wasnt on ebay, it was from another jeep forum. A guy was selling a used full kit for $200..
But that was months ago, and I cant find it now.

If I run into it, I'll let you know.

And you're supposed to use their special fluid for the TC (maybe just the reduction unit)... They must think it is gold because the last time I looked, it was about $20 a qt.

I followed both of those, and it seems they are both discontinued

Actually found a kit on Amazon for $493

Way back in 1988, the part number for the kit was 95-15203 if that helps searching for one.
EDIT: Part numbers could have changed, so make sure it matches your application.

instead of having the quadratrac?

Yes, another option is to install another TCase but that's not going to be any easier. You will still need to install manual hubs in front. But the biggest catch to that plan is the rear axle. Your differential is off-set to the passenger side. Most TCase options would have a centered rear output (except the older Dana 18). That means you may also have to swap out the rear axle with one that has a centered diff (they are common) but then the gearing has to match.
I have seen a jeep that had a Tcase with a centered output and an axle that had an offset diff. The owner said he didn't have any problems but you still end up with much higher angles on the driveshafts than you should. It's not a recommended setup but it works (kinda).

thanks guys i'll keep looking for them because i just like having the control and the knowing that they are locked in. you know what i mean.

Also you would need some type of adapter plate if you want to keep your GM Turbo 400 . If you dont want to do the part time kit Id look for a donor Cj with what you want from the Transmission back.

thats a good idea. i'll have to look around for another jeep to get the stuff i need. does anyone have anything to say about the QuadraTrac ? like does it work good on the trails or is it worth going for the conversion kit

 

[BusaDave9]

QuadraTrac is a good TCase if you keep it well oiled.

If the oil has not been kept up to level you should replace the chain or a part time kit (it replaces most of the wear parts)
