Quadradrive Front Axle Swap to Quadratrac Front Axle Possible?
I have a 99 WJ 4.7 Limited with quadradrive and Vari-lok axles, can i swap to quadratrac full assembly so long as i use the same gear ratio?
The popping in my front is horrible, both axle boots have been torn for a while and the hydra-lok diff is chattering pretty bad. I just wanna swap the front over to quadratrac to eliminate the front hydralok , its expensive to replace. If i replace the shafts and the hydralok still chatters i'd be pissed. So i'll replace the whole unit, the parts place by me has 2 Quadratrac and 2 Quadradrive Front Axles for $400 each, all around 100K miles. This is just for a daily driver. Also is the Quadratrac front driveshaft a Rezeppa shaft or a U-Joint Shaft?

I don't have an answer about part swap compatibility, but have some other thoughts.
Personally, I really like the QD2 setup and the varilocks. They are great for the winter driving here in Utah, and do very well offroad. Replacing the axle shafts isn't too hard. And if there is chatter in the diff, add some friction modifier. That should fix your problem. If you swap to another setup, you will need to have the gears and pinion set properly. Unless you have the tools and experience, it will be expensive to have the gears set. You can't just bolt the parts in, they need to be shimmed and adjusted for the new axle housing they are going into.
In regards to your shaft, just get under and look. The Repezza has covered CV's on each end. The double cardan has a single U-joint on the axle Double U-joint uncovered CV on the t-case end. My Quadradrive II had a double cardan shaft when I bought it, but it could have been changed out.
400 each axle? thats a bit high... have they replaced anything on it? (like the pinion seal, shaft seals etc)
I dont know if all quadra tracks have the same front drive shaft but mine came with the double cardan. I think it varies with the year. All you would have to do is change pinion yokes to make yours fit im pretty sure.
I've got extra replacement differentials and an extra set of shafts if you wanna save a little. I'm not sure how much it costs to get diffs installed though.
I would honestly check your local junkyards for an axle cause 400 is awful high unless its literally ready to bolt on with all new seals and everything checked.
