I have a 83 cj7 and I am looking to see if anyone can help
with a problem?  

My rear end is in need of wheel bearings. I am told that it is needed to pull the hubs in order to change these. There also is a 50
50 chance that we can harm these hubs by pulling them.

I am also told that I could get an after market part to replace both
sides. I think it is called Hub eliminator axle kit.   Not sure.

Can anyone help or send me to someone ? 

Thanks

Allen Drew
