Replacing an axle that had abs with one without abs.

Today I took apart my rear axle because it was shot.. I found the driver side bearings all busted up and scattered every. There was also a ring that was broke inside. This bearing was inside the the cover but closer to the driver side. If I replace my axle with one without abs will it cause any damage? Would I need to do anything with the abs if I'm not using it in the rear? Will the abs still function in the front wheels? Any help is appreciated. This is my first time replacing a axle?
I went to napa and they had a rebuild kit that was around $185, so that's why I'm think just getting a whole axle at a JY would be easier? Anybody know what an axle goes for at a junkyard?

If you install an non-ABS axle in the rear of the vehicle, your ABS system will think the rear ABS sensors are non-functioning. This will cause it to throw a warning code and the light indicating a malfunction will illuminate constantly.

Unless you have experience in setting up rear axle gears (they need to be adjusted for proper lash and for tooth contact pattern), buying a JY axle is much better for your situation. Most JY's offer axles for your vehicle for less than $200

I went to to JU and found the same axle a Dana 35 3.55 gear ratio. We yankee it out and got it for $50 bucks. It came with the brakes and drums. It came off a 97 Cherokee with 197,00 miles but it was in great shape. The only prolblem we had was we had to cut the electrical wires that I beleive were for the abs. I could not find any were I could disconnect them. We took the cover off and every thing was in great shape. We spent the day tearing out the old one on my Cherokee and putting the one we got from the JY. What we did was cripted them together. My Cherokee runs great now but the only problem is that the abs light is still on.

1997-2001 you can disable the ABS by pulling out the ABS relays. Disabling 97-01 ABS will cause no harm, the brakes will function safely and normally. The ABS parts can remain in place, they simply won't function in the ABS mode.

If you are doing more than oil changes and brake jobs, you should own a Cherokee Factory Service Manual. Get a used one from eBay or find an on-line seller for a digital copy.

The ABS relay or relays are in the under hood fuse box.

Would I pull all relays 16-20? Or would I just pull one at a time till I find the one it is?

That is just showing the pin numbers. The actual relay encompasses all 4 of those.

Generally, an ABS axle may be swapped into a non-ABS application without difficulty.

Swapping a non-ABS axle into an ABS vehicle is generally not recommended - but I don't like ABS. I find it useless and limiting (and I've yet to meet an ABS system I wasn't able to lock up the wheels on with only minimal effort.)

The primary difference between ABS and non-ABS axles is simple - there will be one or two "tone rings" and sensors to go with them (depends on whether ABS is implemented at the wheels or at the differential. If it's a four-sensor system, there will be a tone ring and sensor at each wheel. If it's a three-sensor system, each front wheel will have its own tone ring/sensor and the rear axle will have the tone ring mounted under the differential ring gear, with the sensor screwed into the centre section.)

Often, the ABS may be swapped over to the non-ABS axle, as long as the housing ends match up (the ABS shafts are swapped in if they'll fit, and the sensor bracket is usually screwed to the brake assembly or stamped into the backing plate.)

You can also drop the non-ABS axle directly into the ABS application (if it's mechanically compatible,) but expect a persistent ABS fault due to the inability of the system to read the rear axle sensors (because they're not there.) This can usually be corrected by removing the pilot lamp in the IP - although I am unsure of the effect on regular inspections of your vehicle (probably depends on the inspection programme,) and it will need to be corrected if you sell your vehicle. Also, it can cause you headaches with your insurance company, if they're still listing you as getting an "ABS discount" on your policy, and you have a claim, and they find out your ABS is disabled; they can both deny coverage of the claim and pursue you for back premiums (making up for the discount) back to when the ABS was "knowingly disabled" - and/or pursue a claim for insurance fraud.

(I hate it when safety systems get mandated, because those of us who learned to drive without them do quite well, thank you very much. I don't need ABS, I don't want airbags, ...)

The ABS system may be depowered by either removing the connector at the control module or removing the relay that provides power, I'd have to look up which is better. The ABS lamp may be disabled by removing the IP and removing the lamp (just like I need to do with that wretched TPMS in my wife's car. I refuse to pay $40 - or more! - for a sensor just because a two-dollar battery has gone flat, and I catch low tyres before it does anyhow.)

And concur on using a pulled axle over doing an overhaul, if you're a neophyte. An axle is relatively simple (mechanically) to overhaul, but it requires attention to detail, some thinking, and some experience to get done properly - I figured this out when I did my first one (at eight.) The specifications for setting up an axle are fairly tight and definitely unforgiving - set the gears up too tight, and they won't get enough lube. Too loose, and they'll destroy themselves. Contact patch on the wrong place? Teeth will strip, and you're hooped. Break it in wrong? You'll get stress risers, and the gear will grenade on you sooner or later (the housing should still be fine - unless it's an extreme case - but I've seen pinion gears blow up and it's not pretty.) Wheel bearings are pretty easy, carrier bearings just require making sure the shims get put back right, but pinion bearings and gear setup is horribly easy to screw up - and then you've just wrecked the gearset.

I specifically noted 1997-2001 ABS because I have experience with those years, and I know for a fact that the ABS system is stand-alone and can be disabled or even removed.

Earlier Bendix ABS systems, are set up differently and defeating the ABS function can result in no brakes at all.
