So I just got my rear diff completely disassembled, and I used a string line and some creativity to check for housing straightness. Good news is my housing is straight, but I also realized how cruddy the inside of my axle tubes are, rust/sludge/metal chunks. Anybody have a good idea on how to clean em? My rifle bore brushes are to small, and my chimney sweep is to big, lol. Thanks guys.

 

Pressure washer. If that doesn't do it, call your local hardware store and see if they have any sewer pipe snakes. Some of them have a motor which rotates a head and will carve away at things. Stick with the plastic heads.

 

a round wire brush for cleaning boiler tubes?

You need a bigger bore rifle. Oh wait a minute thats called a cannon.

 

I went to the steel supply for a remnant piece of rod to shove down the tube, like scraping concrete, make sure you use the right seals to guide the axles back in without damaging the lips

 

Another trick is to measure the inner diameter and find some pvc that fits but isn't tight.. then apply pressure to the sides you want to clean. Maybe a pellet stove pipe cleaner would work as well.

 

Don't have the answer to that, but, on a similar note, I just finished putting in a new clutch pak on my Diff. and am wondering how long I should wait before the next drain/fill? Do the new steel clutches have a break in period where they lose material that should be flushed before the usual 40K maintenance?

Thanks for the replies guys. I never thought about a boiler pipe brush. It just so happens that my little brother has access to one I can have. And I think I will buy a pressure washer. I've needed one to many times lately not to have one. Plus, I'll be rebuilding my whole front end as soon as I'm done with the back end so I'll want it than too. Thanks again

 

they normally discharge metal, with heavier abuse, change it more often, I do mine at 20k mile intervals. buying a pressure washer is a great investment, youll use it on everything

 

Yes sir, that's about how often I do mine, (every spring) my latest metal chunks were because my pinion gear blew up. I limped it home on some back roads, (about 15 miles in 2nd-3rd gear) I wish now that I would have found a different way to get it home. It messed up the housing pretty good. All the important surfaces are ok though.

 

Paint thinner or brake parts cleaner,,,, ETC ETC ,,, Rag,,,, and a broomstick.

Keep it simple.
