4 Wheel Drive Question

I recently purchased a 2000 Sahara that came with aftermarket REAR locking hubs for towing behind an RV. The hubs have been a pain ever since I bought the car. They are now coming unlocked when I drive, every time I drive. I am planning on gutting them and going back to a standard hub but need to get my Jeep to the shop to do it. Is it safe for me to drive on the street in 4 wheel drive using the front wheels, but keeping the rear ones unlocked, or will this cause more damage?

Thanks in advance!

Just use 4Hi and you should be fine, as long as the back in not locked in. You can even remove the rear drive shaft if that makes you feel better.

Thanks!

Thanks for the quick reply. I thought I would be okay, but have never driven in 4 wheel drive on dry pavement before. I'll be sure to check that the rear driveshaft is completely unlocked before driving though.

Thanks again.

Unfortunate that the previous owner made such a poor decision on that mod. Although I would not recommend driving in 4wh on pavement for extended periods of time,it should be fine in a pinch.

Thanks again for the additional replies. I just unlocked the rear hubs, put her in 4Hi, and made it to the shop with no problems. It did feel like I was eating a ton of tread anytime I made a turn though!

Just get drive flanges for the rear axle.. Having a full float rear end is a good thing, don't convert it back to a semi float.

The last Wrangler to have that characteristic was the 1995 Wrangler YJ. The Wrangler TJ doesn't have that problem.

Well learn something new everyday, thanks jerry, didn't know that I've always been told not to remove the rear shaft and drive it

Why is having a full float a good thing?

Thanks!

The axle shafts bare no weight of the vehicle on them like a semi float axle. They are inherently stronger because they see no shearing forces
