Axle Swap from narrow track to wide track

I have a 1979 CJ7 with the narrow track axles. Can I swap those out for the wide track axles from an 82-86 CJ? If so, what else must i do to finish the job?

yup, should be plug and play. They are identical except for the width.

Steering linkage isn't identical. The wide track linkage must also come with the wider front axle.

Shock mounts are also different on wide tracks.

Correct me if I'm wrong but couldn't you just change wheels from an 8" wide to a 10" wide with the same back spacing and gain almost the results as using a wide track with 8" wide wheels? This is assuming that you are currently using 8" wide wheels and something like 33x12.5 tires.

Does the widetrack rear axle come with 2 piece axles just like the narrow track did?

I think the NT hubs are also stronger, if I remember correctly the later CJ's had weak 6 bolt compared to the earlier 5 bolt design...or the other way around. I ran wheel spacers for years and it was good. I recently went back to stock width for nostalgic reasons.

yeah the old NT's had the 6bolt hubs and I know my WT has the 5bolt. But there is a thread for switching the WT's back to the 6bolt hub somewhere on here. I dont feel like searching for it though.

No. You aren't spacing the wheels any further from the frame doing this. You'd have to go to a wheel with less backspace to do what going to wider axles does.

I just swapped out my NT axles to WT just over a month ago. Everything is a clean swap. I removed the hubs, rotors, brake horns and calipers from the NT which were 6 bolt and swapped out the hardware on the WT. The only other part you might need is the longer steering link for the WT axles, I actually have one from the donor vehicle still. Also, I don't know if it matters i changed the U joint straps (screw type) on the WT to the U-bolt style that the NT had.

I just swaped the narrow tracs out of my 75 for wide tracs out of an 84 and did have to mount new spring mounts on the rear I have a T18 4 speed I had 4:27 in it and went to a 2:73 so I could drive it faster than 45 miles per hour plus the ring and pinion in the front was gone. Now I am shifting different does the T18 have syncronizers in it
