HP Dana 30 find today - possible to keep anti lock brakes?

I just got back from the junkyard a little while ago with a HP Dana 30 sticking out of the back of my Neon for $90 out the gate. I had to pull it and lift it into the back of the Neon myself but it was worth it. I also grabbed a NP242 last week for my rig from the same yard for $45.

I still need a trans for my Jeep so no crap about driving a Neon please.




I'm moving up to 33's next week (they are on their way) and figured the HP and 4.10's would be a good move while I'm at it. Plans are to install an 8.8 as well out back and I was wondering if there was any way I could keep the anti lock brake system? What do you guys do about the tone rings?

If not, is it just a matter of pulling the relay? Anything else that needs to be done to disable the anti lock brakes?

You can certainly keep the front ABS. Swap the knuckles from your LP D30 onto the HP D30 - it's a straight swap. Then, put in your ABS axles, and you're done.

I don't know about the 8.8 though. I think if you search for this, you'll find people simply pull the relay and forget about it.

Yeah, the only problem is my ABS axles are CV which I'd like to get rid of in favor of the stronger U Joint axles that are already in the HPD30. I guess I could pull a set of ZJ axles that are U Joint and have tone rings and use those.

Either that, or ditch the ABS all together and just forget about it. It may be more trouble than it's worth.

Not quite. Quadra-Trac ZJs are the only ones that came with the CV front axles. The ZJs equipped with the 242 came wit the 297X series front shafts. I got lucky enough to go pull the 297X style front shafts from pullapart for $35. Also any front shafts out of a TJ or later XJ will work. I would recommend the TJ shafts as they are about 20% stronger(bigger U-Joint.) Hope this helps. Oh, and buy a breaker bar and WD-40 to take the wheel bearings off. The JY ZJ was rusted to sh*t and it bent the heck out of the wrench i was using.

EDIT: The wheel bearing bolts are 13mm 12-point. Be careful.

I'm just going to reuse the XJ shafts that I got with the axle.

It looks like it's not worth the trouble to keep the ABS.

Won't be able to keep it. In the zj if one sensor isn't working the whole system stops working.

The 8.8 will eliminate your ability to use rear abs.

No need to pull a fuse or anything.

The 8.8 can be modified to use ABS. It's a pain thought.

I didn't take the time to look at the production year.

I was just happy to find one that had 4.10's. There was another one there (older) as well, but it had the passenger side vacuum disconnect.

They don't last long in the Pick and Pulls around here.

Stumbled across a couple NP231's and a few more NP242's too. They were laying on the ground from someone taking the transmissions out.
