ABS Pump replacement for 2006 Jeep Liberty Limtited

Hi all,

This is a separate post about an issue with my Jeep that I've separated into two threads (for the two separate-but-related issues). About 8 months ago I bought a used '06 Liberty Ltd. Overall it's in great shape, and all of the features work really well... Obviously well taken-care-of by the previous owners.

It IS having an issue with the ABS that caused me to take it in to the dealership for service. Long story short, after a bunch of checking things out, they say that there are 2 problems... the ABS controller is broken and needs to be replaced (which I'll address in a separate thread for clarity), and the rear wheel bearings are failing and need to be replaced.

The ABS pump is apparently broken and loose, which is causing an "ABS pump low voltage" code to come up, and causing the ABS system to disengage (which also disengages the Cruise Control).

If I were to get the parts online, can I just bring them to any regular mechanic to install? One guy I talked to said that only dealerships can do ABS work because of the computer-calibration that needs to be done, but the dealership I brought it to said they couldn't fix it because they don't have the parts. I realize that brakes are tricky because they're so integral to safety, so I don't really want to try and install the ABS controller myself (which I do like to do usually), but I don't want to just leave it as-is.

Any advice would be appreciated!

Thanks,
Joe

Maybe you can delete the ABS entirely with some junkyard shopping? Our '05 has none at all (factory).

 

Cheap parts... basic Dodge stuff. Get yourself a slide-hammer with the right attachments, and a seal driver kit.

Unless ABS models are different?

 

Yes, as a worst case scenario you may have to pull the axle, take it to the garage and get them to press the old bearings off, and the new on as they can be pretty stubborn, but everything else is well within the reach of the average home mechanic.

Just remember to be careful when reassembling the ABS to line the sensor up properly when you mount it otherwise you might have to fiddle with it after.

The Dodge 8.25" is a C-clip axle.... bearing sits in the housing, not on the shaft.

^ He covers seal replacement around the 10min mark.

Thanks for that, I work on several different types and forgot which one the Liberty has as ours hasn't needed any work for years. [emoji846]

Thanks for the advice everyone. I don't have a lot of my own tools or equipment at home, but I found a nearby "rental garage" that lets you use all of their tools and equipment if you rent out one of their bays. I think I'll do that if I can get the parts delivered, since I'll also have to change the differential fluid and gasket glue when I remove the axle, plus I think they have bearing pullers and presses there too. I'm going to give them a call and see if they've got what I'll need.

On the topic of the ABS, I've read that the the system needs to be "flashed/programmed" by the Dealership after it's installed. If I do the work myself (reinstalling the ABS Control Module, flushing the brake fluid, etc.), will the brakes work to get me to the Dealership, or will I need to have it towed there, or how does all that work?

They should work fine (perhaps without any ABS ability) for a short drive to a dealership to get the reprogramming done.

Yes, after watching a few YouTube videos and such, I do see that the bearings are in the shaft housing near the wheel. You do have to open up the differential though so you can get the c-clip off to get the axle out. All in all, it seems very straightforward, so I'll likely do this myself when I can get the parts ordered.

Thanks again!

 

Is there something actually wrong with the backing plates? They're quite robust (cast) unlike some others with a stamped tin plate that rusts away.

A hardware kit, shoes, and some elbow grease is usually all it takes to have operable parking brake again. BTDT.
