Muffler bearing inspection

There was a long post on the toy bbs about muffler bearings, and it never was really resolved, I did a little research on this very obscure subject, so just in case anyone over here is interested, here is the way to check out the function of your muffler bearings.

Maybe on a Bronco but, aren't they on the driver's side on a CJ?

Why drive a luxo-box SUV when you can lay in the dirt busting your knuckles under old iron? '77 CJ-5, '64 S2A Land Rover

Re: Muffler bearing inspection

It's because the seals aren't high temperature. You need to specify them when you get the new bearing.

Re: Muffler bearing inspection

http://www.kalecoauto.com sells new muffler bearings and they're a great source for other need to own parts. They also have a forum for help on vehicle use and maintence which is frankly speaking superior to any currently on the web.

ExtinctJeep beat me to it. If you have not been to kalecoauto.com you owe it to your self to take a look at it.

Re: Muffler bearing inspection

I'm glad for that link. My local part store has been selling them to me for $100 a crack. The worst part is I'm not sure they fit right and they won't refund my money. All I've been able to do was to keep going back and buying more hopeing to get the right one. I'm kinda mad since I've bought 8 and none of them have fit. I'll try this place and see if they can do me any better. If anyone needs any, maybe mine will work for you..........I'll sell them 1/2 price. $50 ea.[img]/wwwthreads_images/icons/tongue.gif[/img]

Re: Muffler bearing inspection

Mine were giving me the worst time. But I found the solution. You need to buy the special muffler bearing packer. Eliminated all of my headaches.

Re: Muffler bearing inspection

You guys crack me up! . I have found that the easiest way to instal them is to stick the muffler in the frezzer over night and put the bearing in the oven for ten minuits then you dont' even need them pressed on. LOL

Re: Muffler bearing inspection

The reason your muffler bearings keep failing is improper maintenence. You are probably using "wheel bearing" grease instead of the extreme hi temp muffler bearing grease. The grease is kinda' spendy ($60 a tube) but I have some extra if anyone needs some. The guy at Checker Auto told me it was mislabeled as lubriplate but it is the gen-u-ine stuff we need for our problem. I'll let anyone have a tube at the above cost.
