Things To Tackle When Doing Brake Conversion...

So what else should I do when I do my disk brake conversion.

I am gonna have the axel open, so what else should I be thinking of doing/replacing?

Worth it to re-gear? Have the 8.25 (00 cherokee sport), will be running 33x12.5"s on a 3.5" lift. If I do re-gear what else is involved in that.

What else should I replace when I do the brake conversion, bearings? Joints? Wanna get as much handled as possible.

Thanks

Re-gearing is a totally seperate issue and to try and do both while you are working on the axle is going to turn it into a mammoth task. As you are asking this question I guess you don't have the experience to re-gear yourself? Just keep it simple and do the disc conversion as a stand-alone project. All you would be saving by doing both together would be the oil used to refill the axle.

If your axle is sound now then all I would replace is the hub seals as they might start leaking once they have been disturbed and that can lead to oily handbrake shoes and pads (ask me how I know?).

Here's a pointer on the hub seal change - 8.25 hub seal replacement

By the way, I cut my own paper/card gaskets from a big sheet of gasket paper off eBay and if you grease it before using it it can often be reused many times and is a lot easier and more reliable than RTV sealent.

Are you pulling the disk brakes from a ZJ? That's what I used a while back. Recently I went to the JY and pulled the E-brake cables from a ZJ even though everyone said they can't be used... They can't w/ the current XJ "mix box". I used the ZJ "mix box" and mounted it in the DS tunnel under the rear seat and it worked pretty well. Something to keep in mind and save from buying Liberty cables.

Now, to steal a little on the threat:
What lubricates the rear axle bearings? Is is grease or Gear oil?

yeh, I am pretty much scrapping the e-brake for the time being. I need to redo the entire system, it's F****D.

Actually talked with a local brake shop and the guy who runs it might be helping me with the conversion cus he has been wanting to do it himself for ages.

The bearings in the C-clip axles (Dana 35 or Chrysler 8.25) are lubricated by the gear oil from the pumpkin that sloshes around the axle tubes while cornering and on sideslopes. I have never seen one but I believe the none C-clip Dana 35 axle from the earlier models (1980's?) have greased bearings that are seperate from the axle oil.

someone recommended I change those bearings out when I do the brake conversion. Just have little idea of how to do that myself. It makes sense though given I am sure they are somewhat worn.

It was probably me. They're pretty easy with a slide hammer.
