How to replace muffler bearings?

Hey guys, I was driving my jeep last night and the muffler was starting to get really loud. I looked under it this morning and opened up my muffler and the bearings were worn out. I bought a new set of bearings but I'm not sure how to install them. Here's a pic .any help would be great. Thanks

Oh, those are easy to replace. the pain is that you also have to replace your flux Capacitor along with the new muffler bearing.

Them flux capacitors I tell ya! So that would mean I'd have to drain the hydraulic oil from my leaf springs to be able to reach where the flux capacitor is , right??

You are soooooo lucky to have the Special Snap-on Tool to remove those bearings !
That tool alone is worth it's weight in gold....
I used teflon sliders in my leaf springs so I don't need to drain em anymore, smartest thing I ever did !
So far I been pretty lucky, haven't had a Flux cap. go bad yet, i found if ya keep em dry they last forever... "BH"

Check your blinker fluid while you're at it, you'll need a left handed screwdriver for it though.

The biggest problem i've had when replacing muffler bearings is finding the right size o-ring stretcher for the job. after that it's all easy.

The stealership will send you a how to dvd but the only problem is you have to buy a dvd rewinder to be able to watch it more than once.

Don't forget to add the bearing brands stickers to get the bearings full potential. I'd hate for u to pay for the promised 25 hp and only get 10 hp.

Once one replace those bearings...make sure ya plastidip the hell out your jeep to make it cool. Then be sure to start a new post "Hey look what I plastidipped today" for every component that has been sprayed When it peels, don't worry, just buy 14 more cans of plastidip.

Oh, and someone already started a thread once about plastidipping Jeep seats, so you don't need to start a thread on that.

Might as well do the Catalytic Converter Bearings as well. If the ceramic inside is not cooked evenly at 210-230 degrees on all sides it will not take the necessary particles out of the exhaust and set off a O2 sensor or destroy your cat.

Definitely an interesting and helpful thread. I think that the only thing that I need to know about now is when is the right time to change air in my tires from Summer air to Winter Air.

Don't forget the wind repellent for the windshield. I always keep a bottle in the Jeep. Works great for keeping all that bug kill off my windshield.

The sky hooks have to be big enough to keep the Johnson rod from contacting the muffler bearings, if not they will disintegrate !

If the cooling fan for the Johnson rod is not functioning correctly it may not extend far enough to open the oil pan flap to release all your oil. But make sure when that happens to refill your oil using the refill cap on your headers

Couldn't find a good how-to video on the muffler bearings but here is one on the blinker fluid.

Just wait until you have to replace the O-Pipe before the muffler. That's a real doozie!

Also don't forget when doing your disc brakes to pick up a gallon of rotor wash...
